Tagged: asus, ASUS ROG, ROG Swift, swift PG27AQ, ips display, 4k, 60hz
The 165Hz G-SYNC compatible ASUS ROG Swift PG279Q was recently on the PCPer review bench, garnering a Gold Award for its performance. Kitguru recently wrapped up a review of a slightly different model, the ROG Swift PG27AQ. Like the other model it is a 27" IPS display which supports G-SYNC, however only to 60Hz as it is a 4K (3840×2160) monitor. The bandwidth required to provide adaptive refresh at higher than 60Hz on a 4K display just isn't really available yet, so you have to make a choice between a high resolution or a high maximum refresh rate. Next year we will see monitors capable of this as the DisplayPort interface is updated. For now take a look at the review to see which you prefer between resolution and refresh rate.
"The ROG Swift PG27AQ is a 4K gaming monitor from Asus that supports Nvidia G-Sync up to 60Hz. It’s a 27-inch IPS display with a 4ms response time and a 10-bit colour panel. Add on a flexible stand with pivot, tilt and rotate support, with a redesigned software interface, and it could be a contender for the best gaming display on the market."

In the comments to our recent review of the ASUS ROG Swift PG279Q G-Sync monitor, a commenter by the name of Cyclops pointed me in the direction of an interesting quirk that I hadn’t considered before. According to reports, the higher refresh rates of some panels, including the 165Hz option available on this new monitor, can cause power draw to increase by as much as 100 watts on the system itself. While I did say in the review that the larger power brick ASUS provided with it (compared to last year’s PG278Q model) pointed toward higher power requirements for the display itself, I never thought to measure the system.
To setup a quick test I brought the ASUS ROG Swift PG279Q back to its rightful home in front of our graphics test bed, connected an EVGA GeForce GTX 980 Ti (with GPU driver 358.50) and chained both the PC and the monitor up to separate power monitoring devices. While sitting at a Windows 8.1 desktop I cycled the monitor through different refresh rate options and then recorded the power draw from both meters after 60-90 seconds of time to idle out.
The results are much more interesting than I expected! At 60Hz refresh rate, the monitor was drawing just 22.1 watts while the entire testing system was idling at 73.7 watts. (Note: the display was set to its post-calibration brightness of just 31.) Moving up to 100Hz and 120Hz saw very minor increases in power consumption from both the system and monitor.
But the jump to 144Hz is much more dramatic – idle system power jumps from 76 watts to almost 134 watts – an increase of 57 watts! Monitor power only increased by 1 watt at that transition though. At 165Hz we see another small increase, bringing the system power up to 137.8 watts.
Interestingly we did find that the system would repeatedly jump to as much as 200+ watts of idle power draw for 30 seconds at time and then drop back down to the 135-140 watt area for a few minutes. It was repeatable and very measurable.
So, what the hell is going on? A look at GPU-Z clock speeds reveals the source of the power consumption increase.
When running the monitor at 60Hz, 100Hz and even 120Hz, the GPU clock speed sits comfortably at 135MHz. When we increase from 120Hz to 144Hz though, the GPU clock spikes to 885MHz and stays there, even at the Windows desktop. According to GPU-Z the GPU is running at approximately 30% of the maximum TDP.
Though details are sparse, it seems pretty obvious what is going on here. The pixel clock and the GPU clock are connected through the same domain and are not asynchronous. The GPU needs to maintain a certain pixel clock in order to support the required bandwidth of a particular refresh rate, and based on our testing, the idle clock speed of 135MHz doesn’t give the pixel clock enough throughput to power anything more than a 120Hz refresh rate.
Pushing refresh rates of 144Hz and higher causes a surprsing increase in power draw
The obvious question here though is why NVIDIA would need to go all the way up to 885MHz in order to support the jump from 120Hz to 144Hz refresh rates. It seems quite extreme and the increased power draw is significant, causing the fans on the EVGA GTX 980 Ti to spin up even while sitting idle at the Windows desktop. NVIDIA is aware of the complication, though it appears that a fix won’t really be in order until an architectural shift is made down the road. With the ability to redesign the clock domains available to them, NVIDIA could design the pixel and GPU clock to be completely asynchronous, increasing one without affecting the other. It’s not a simple process though, especially in a processor this complex. We have seen Intel and AMD correctly and effectively separate clocks in recent years on newer CPU designs.
What happens to a modern AMD GPU like the R9 Fury with a similar test? To find out we connected our same GPU test bed to the ASUS MG279Q, a FreeSync enabled monitor capable of 144 Hz refresh rates, and swapped the GTX 980 Ti for an ASUS R9 Fury STRIX.
The AMD Fury does not demonstrate the same phenomenon that the GTX 980 Ti does when running at high refresh rates. The Fiji GPU runs at the same static 300MHz clock rate at 60Hz, 120Hz and 144Hz and the power draw on the system only inches up by 2 watts or so. I wasn't able to test 165Hz refresh rates on the AMD setup so it is possible that at that threshold the AMD graphics card would behave differently. It's also true that the NVIDIA Maxwell GPU is running at less than half the clock rate of AMD Fiji in this idle state, and that may account for difference in pixel clocks we are seeing. Still, the NVIDIA platform draws slightly more power at idle than the AMD platform, so advantage AMD here.
For today, know that if you choose to use a 144Hz or even a 165Hz refresh rate on your NVIDIA GeForce GPU you are going to be drawing a bit more power and will be less efficient than expected even just sitting in Windows. I would bet that most gamers willing to buy high end display hardware capable of those speeds won’t be overly concerned with 50-60 watts of additional power draw, but it’s an interesting data point for us to track going forward and to compare AMD and NVIDIA hardware in the future.

The new Acer Predator X34 claims a “world's first” as a curved 34-inch IPS G-SYNC gaming monitor, and from appearance to specs the new display looks very impressive.
- Curved 34-inch IPS 21:9 ultra-wide QHD display
- 3440x1440 @ 60 Hz resolution
- 4 ms response time
- 100,000,000:1 max contrast ratio
- 300 cd/m2 brightness
- 1.07 billion colors (10-bit)
- 100% sRGB
- Panel supports overclocking to 100Hz
- NVIDIA G-SYNC technology
- Two 7W speakers enhanced with DTS Sound
- Zero frame design maximizes viewing area
- Tilt from –5 to +35 degrees, height adjustments up to 5 inches
- Connectivity includes HDMI, DisplayPort 1.2, and 4x USB 3.0 ports
The 60 Hz native refresh rate might cause comment, but the adjustable overclocking up to 100 Hz should satisfy those looking for a better high FPS experience, though at 3440x1440 it would be difficult to max out even 60 Hz with the newest games at ultra settings if you're running a single GPU. And if you do play at the highest settings the included NVIDIA G-SYNC variable refresh technology will certainly help with those moments when the game is outputting much less than 60 FPS.
So how much will the new Predator X34 set you back? Acer says the monitor will be available “at leading online retailers in the United States” for a cool $1299.

Okay, we see a lot of monitors here at PC Perspective...but this is probably the current "most coveted" of them all. The ASUS ROG Swift PG279Q looks nearly identical to the first generation ROG Swift display but with a couple of key modifications. Yes, this is still a 27-in 2560x1440 monitor but this time...oh this time...it holds a 165 Hz IPS screen.
Moving away from the world of TN screens and into the image-quality-improvement of IPS, the PG279Q not only brings ASUS' first G-Sync capable IPS 2560x1440 panel to the world but also ups the ante more than any other screen we have seen when it comes to the maximum refresh rate: this beast will top out at 165 Hz! High performance gamers that have taken to the 144 Hz market will surely see the advantages of stepping up yet again though I am curious how ASUS is able to drive an IPS screen at this speed without artifacts or issues.
Interestingly, this panel not only includes a DisplayPort connection for 165 Hz 2560x1440 throughput but also an HDMI 1.4a input that can run 2560x1440 at 60 Hz, should you need that kind of thing. If you prefer ULMB over G-Sync, you have that option as well.
I'm not sure yet, but I can feel Allyn's trigger finger on the BUY NOW button...if it existed. We don't have pricing and we don't have any update on availability, but if our past experiences with the ROG Swift line are any indication, I have a feeling this display is going to impress.

Tagged: asus, ROG, swift, pg27aq, 4k, g-sync, gsync
Back at CES we first got to see the ASUS ROG Swift PG27AQ, a 4K resolution IPS G-Sync enabled gaming monitor with all the fit and finish we came to love with the first ROG Swift display. Today, as part of the ROG Unleashed event being held in San Jose, the monitor has been officially unveiled.
The build and specifications remain pretty much unchanged though pricing and availability are still up in the air.
The ASUS PG27AQ updates and changes the ROG Swift design and style in small areas including adding an illuminated Republic of Gamers logo to the base along with the red circle. The stand includes supports for height adjustment, rotation, and tilt - basically mirroring the capability of the original ROG Swift.
Seeing a 4K IPS G-Sync monitor warms my heart though I wonder if we will need the next generation of NVIDIA GeForce GPUs to be able to power it effectively with a single card. G-Sync variable refresh rate technology does mean that gamers will be able to run at lower frame rates without the worry of screen tearing or judder.
Finally, even though the display has support for HDMI, it will only run at 4K / 24 Hz or 1080p / 60 Hz - there is no true HDMI 2.0 support to be found. The full resolution and refresh rate, as well as G-Sync support, are enabled through the DisplayPort connection only.

Tagged: UP3216Q, ultrasharp, UHD, monitor, ips, HDMI 2.0, display, dell, calibration, Adobe RGB, 4k
While not officially launched in the U.S. just yet, on Thursday Tom's Hardware reported news of a trio of upcoming UltraSharp monitors from Dell, the largest of which - the UP3216Q - I was able to locate on Dell's Bermuda site.
For anyone looking for a 4K display for photo or video editing (or any other color critical work) the new Dell UltraSharp UP3216Q looks like a great - and likely very pricey - option. Just how much are we talking? The existing 31.5-inch 4K UP3214Q carries a $1999 MSRP (though it sells for $1879 on Dell's site). For this kind of money there are probably those who will never consider a 16:9 option (or ever give up their 16:10 30-inch displays), but the specifications of this new UP3216Q are impressive:
- Diagonal Viewing Size: 31.5 inch
- Aspect Ratio: Widescreen (16:9)
- Panel Type, Surface: In-Plane Switching
- Optimal resolution: 3840 x 2160 @ 60Hz
- Active Display Area (H x V): 273,996 sq-mm (424.7 sq-inches)
- Contrast Ratio: 1000 to 1 (typical), 2 Million to 1 (dynamic)
- Brightness: 300 cd/m2 (typical)
- Response Time: 6ms fast mode . GTG
- Viewing Angle: 178° vertical / 178° horizontal
- Adjustability: Tilt, Swivel, Height Adjust
- Color Support: 1.07 billion colors
- Pixel Pitch: 0.182 mm
- Backlight Technology: LED light bar system
- Display Screen Coating: Anti-Glare with 3H hardness
- Connectivity: DP, mDP, HDMI (MHL), 4 x USB3 with one charging port, 1 x USB3 upstream, Media Card Reader
With the 60 Hz 4K (UHD) IPS panel offering full sRGB and 99.5% Adobe RGB, and a factory calibration that promises to be factory color calibrated with a deltaE of less than 2, the UP3214Q sounds pretty much ready to go out of the box. However for those inclined to strive for a more perfect calibration Dell is offering an X-Rite i1Display Pro colorimeter as an optional accessory, providing their own Dell UltraSharp Color Calibration Solution software.
A couple of points of interest with this monitor, while it offers DisplayPort and mini-DP inputs it also supports 4K 60 Hz via HDMI 2.0. Color support is also listed as 1.07 billion colors, but it's not specified whether this indicates a 10-bit panel or if they are implementing 10-bit color processing with an 8-bit panel - though if it's in the $2k price range it would probably safe to assume this is a 10-bit panel. Lastly, in keeping with the UltraSharp branding the monitor will also carry Dell's Premium Panel Guarantee and 3-Year Advanced Exchange Service warranty.

Tagged: ROG Swift, PG348Q, monitor, ips, IFA 2015, gaming monitor, g-sync, asus, 3440x1440, 21:9, 100Hz
The latest ROG Swift monitor from ASUS is the PG348Q, which features a curved 34-inch IPS 21:9 display.
The ROG Swift PG348Q offers 3440x1440 resolution from its 100 Hz IPS panel, and includes NVIDIA G-SYNC technology. The new ROG Swift is said to have a "frameless curved design", but as we saw with the recently reviewed ASUS PB258Q monitor this might not be quite as frameless after all, but we shall see.
The ROG Swift PG348Q features full tilt, swivel, and height adjustments, and offers a couple of ASUS-specific features including GamePlus, which "gives users four different crosshair options, an in-game timer and an FPS counter for an added advantage in first-person-shooter and real-time-strategy games", and GameVisual, which "provides six preset display modes for optimized gaming visuals".
Pricing and availability of this latest ROG Swift has yet to be announced.

Tagged: Predator Z35, IFA 2015, gaming monitor, g-sync, curved, acer, 2560x1080, 21:9
Acer has announced a pair of gaming monitors, beginning with their first curved NVIDIA G-SYNC monitor, the Predator Z35.
This 21:9 UltraWide display features a 2560x1080 resolution and supports overclocking for up to 200 Hz refresh. The Predator Z35 certainly looks the part, with angular styling and a dramatically curved (2000R curvature) screen that promises to help provide immersive gameplay.
Next up is the Predator XB1 Series, which consists of both 27-inch and 28-inch models.
All monitors in the Predator XB1 Series feature NVIDIA G-SYNC technology, with resolution the differentiating factor between the two 27-inch models.
The 27-inch models (XB271HK / XB271HU) feature a ZeroFrame edge-to-edge design with 4K UHD (3840 x 2160) or WQHD (2560 x 1440) IPS panels that support 100% of the sRGB color gamut, while the XB271HU supports NVIDIA ULMB and refresh rates of up to 144Hz. The 28-inch model (XB281HK) features a 4K UHD panel that has a fast GTG (gray to gray) response time of 1ms, rendering fast-moving actions or dramatic transitions smoothly without smearing or ghosting.
Pricing for the Predator Z35 will be $1199, with XB1 starting at $799. The Z35 will be available in the U.S. in December, while the XB1 will be available in November.

Dell announced a new 27-inch WQHD gaming monitor yesterday, and while the 2560x1440 resolution and TN panel are nothing new the real story is
the inclusion of NVIDIA G-Sync Gen II that there was a typo in the release.
Dell provides these details about the S2716DG monitor:
- Nvidia’s G-Sync Gen II support feature synchronizes GPU and monitor to minimize graphic distortions and screen tearing
- Quad HD resolution of 2560 x 1440 with close to 2 times more onscreen details than Full HD
- A full range of adjustability features, like tilt, pivot, swivel and height-adjustable stand allow for long hours of comfortable gameplay
- A wide range of connectivity features, including DisplayPort 1.2, HDMI 1.4, four USB 3.0 ports, USB 3.0 upstream, Audio line-out & Headphone-out
- 144 Hz maximum refresh rate and 1ms response time
Pricing is listed as $799 and the S2716DG will be available October 20.
UPDATE: Looking at the Dell announcement page, the company links to a Quadro PDF using a technology called G-Sync II. The problem is that technology was releaesd in 2011 and served a very different purpose than the G-Sync we use for gaming monitors today. We always knew that re-using that name would haunt NVIDIA in some ways...this is one of them. So, that means that Dell's reference to a second generation of G-Sync here is simply a typo, or the naming scheme is correct but the writer of the press release linked to something unrelated.
It is possible that a new version of the G-Sync module is on its way with updated features and possibly support over other display outputs, but I haven't heard anything official as of yet. I'll keep digging!
UPDATE 2: Just confirmed with Dell, this was a typo! The S2176DG "was incorrectly listed as "G-Sync Gen II" and the accurate name of the technology is NVIDIA® G-SYNC™." There you have it. False alarm!

Tagged: Intel, freesync, DisplayPort, adaptive sync
DisplayPort Adaptive-Sync is a VESA standard, pushed by AMD, that allows input signals to control when a monitor refreshes. A normal monitor redraws on a defined interval because old CRT monitors needed to scan with an electron gun, and this took time. LCDs never needed to, but they did. This process meant that the monitor was drawing a frame whether it was ready or not, which led to tearing, stutter, and other nasty effects if the GPU couldn't keep up. With Adaptive-Sync, GPUs don't “miss the train” -- the train leaves when they board.
Intel has, according to The Tech Report, decided to support Adaptive-Sync -- but not necessarily in their current product line. David Blythe of Intel would not comment on specific dates or release windows, just that it is in their plans. This makes sense for Intel because it allows their customers to push settings higher while maintaining a smooth experience, which matters a lot for users of integrated graphics.
While “AMD FreeSync” is a stack of technologies, VESA DisplayPort Adaptive-Sync should be all that is required on the monitor side. This should mean that Intel has access to all of AMD's adaptive refresh monitors, although the driver and GPU circuitry would need to be their burden. G-Sync monitors (at least those with NVIDIA-design modules -- this is currently all of them except for one laptop I think) would be off limits, though.

The response to Al's review of the ASUS MG279Q was, to be polite, somewhat energetic. While not much was learned a lot of opinions were voiced and occasionally they were even on topic. The Tech Report, not dissuaded by the response just posted a 10 minute video offering their thoughts on the new Freesync technology in general and this monitor specifically. The Closed Caption feature offers some rather amusing translations of what is being said but you should pay attention to what is actually being said as the video offers a good overview of what FreeSync is.
"Asus' MG279Q is a 27" FreeSync monitor with a 144Hz, 2560x1440 IPS panel for an appealing price. Our own Gyromancer, Nathan Wasson, has spent some quality time with the MG279Q, and he's collected his impressions in video form."

availability of the beta version of their GameWorks VR. As mentioned on this podcast, until now your GPU has treated the Oculus as a secondary monitor but with this update your graphics driver will directly talk to the Oculus as a separate device, which should help greatly with latency and development of the tricks and treats yet to be discovered when programming for this type of interface.
Tagged: nvidia, oculus rift, gameworks vr
NVIDIA's Gameworks VR, as well as AMD's LiquidVR will provide a platform for developers to program for the Oculus Rift as well as the competeing products from other companies. The new beta SDK from NVIDIA has been updated to support VR SLI and is compatible with the new 350.60 Game Ready drivers. Programmers working with the Maxwell architecture will benefit from Multi-Res Shading which should increase the performance of your current programs. Follow the links if you are interested in developing for Oculus, otherwise wait patiently for the day you can pre-order them.
If you live somewhere you can visit or order from a Microcenter and consider a great value enough reason to use a TN based display then check out this deal on an AOC U2870VQE 28" 4K LED display. Currently only $349+taxes you can get a 4k display for your computer or to stream to from your mobile device. Again, at this price you cannot expect either adaptive refresh rate technology but for roughly the same price to pick up an IPS based FreeSync or G_SYNC monitor of comparable size you can grab three of these displays. Connectivity includes VGA, DP, Mini-DP and HDMI (MHL), the latter of which is compatible with mobile devices.
The display is sold as a 10-bit panel, in fact it is an 8bit panel which uses Frame-Rate-Control to up the number of colours to 1.07 billion but frankly unless you are using this for professional purposes you are not going to notice any difference; except the price of course. You can see the full news release below the fold, or just click on that link to order one for as you might expect, the supplies at this price are limited. Otherwise you can keep saving your pennies for a 4k IPS display with true 10bit colour and one of the two adaptive refresh rate technologies.

At Computex this week ASUS is showing off a prototype of the new ROG 3800R monitor, a 34-in curved display with a 3440x1440 resolution and G-Sync variable refresh rate capability. ASUS claims on its PCDIY blog that the 21:9 aspect ratio was the one of the "most requested" specifications for a new ROG monitor, followed by a curved design. The result is a gorgeous display:
Here's a list of specifications:
- 34” optimal dimension for QHD resolutions with 3440×1440 resolution
- 21:9 ultra-wide aspect ratio for increased immersion and improved horizontal workflow
- IPS based panel for superior color reproduction, black levels and reduction of color shifting
- NVIDIA G-SYNC equipped offering smooth, fluid and tear free gaming with improved motion clarity. Additionally equipped with ULMB operating mode for outstanding motion clarity.
- Frameless design for seamless surround gaming
- ASUS exclusive GamePlus feature and Turbo Key
- Ergonomic adjustment including tilt, swivel and height adjustment
Hot damn, we want of these and we want it yesterday! There is no mention of the refresh rate of the display here though we did see information from NVIDIA that ASUS was planning a 34x14 60 Hz screen - but we are not sure this is the same model being shown. And the inclusion of ULMB would normally indicate a refresh rate above 60-75 Hz...
Another interesting note: this monitor appears to include both DisplayPort and HDMI connectivity.
This 34-inch 3800R curved display features wide-viewing angles, a 3440 x 1440 native resolution, and 21:9 aspect ratio. It features NVIDIA® G-SYNC™ display technology to deliver smooth, lag-free visuals. G-SYNC synchronizes the display’s refresh rate to the GPU in any GeForce® GTX™-powered PC to eliminate screen tearing and minimizing display stutter and input lag. This results in sharper, more vibrant images; and more fluid and responsive gameplay. It has extensive connectivity options that include DisplayPort and HDMI.
The above information came from ASUS just a few short hours ago, so you can assume that it is accurate. Could this be the start of panels that integrate dual scalars (G-Sync module plus something else) to offer more connectivity or has the G-Sync module been updated to support more inputs? We'll find out!

In conjunction with the release of the new GeForce GTX 980 Ti graphics card today, NVIDIA is making a handful of other announcements around the GeForce brand. The most dramatic of the announcements center around the company's variable refresh monitor technology called G-Sync. I assume that any of you reading this are already intimately familiar with what G-Sync is, but if not, check out this story that dives into how it compares with AMD's rival tech called FreeSync.
First, NVIDIA is announcing a set of seven new G-Sync ready monitors that will be available this summer and fall from ASUS and Acer.
Many of these displays offer configurations of panels we haven't yet seen in a G-Sync display. Take the Acer X34 for example: this 34-in monitor falls into the 21:9 aspect ratio form factor, with a curved screen and a 3440x1440 resolution. The refresh rate will peak at 75 Hz while also offering the color consistency and viewing angles of an IPS screen. This is the first 21:9, the first 34x14 and the first curved monitor to support G-Sync, and with a 75 Hz maximum refresh it should provide a solid gaming experience. ASUS has a similar model, the PG34Q, though it peaks at a refresh rate of 60 Hz.
ASUS will be updating the wildly popular ROG Swift PG278Q display with the PG279Q, another 27-in monitor with a 2560x1440 resolution. Only this time it will run at 144 Hz with an IPS screen rather than TN, again resulting in improved color clarity, viewing angles and lower eye strain.
Those of you on the look out for 4K panels with G-Sync support will be happy to find IPS iterations of that configuration but still will peak at 60 Hz refresh - as much a limitation of DisplayPort as anything else though.
Another technology addition for G-Sync with the 352-series (353-series, sorry!) driver released today is support for windowed mode variable refresh.
By working some magic with the DWM (Desktop Window Manager), NVIDIA was able to allow for VRR to operate without requiring a game to be in full screen mode. For gamers that like to play windowed or borderless windowed while using secondary or large displays for other side activities, this is a going to a great addition to the G-Sync portfolio.
Finally, after much harassment and public shaming, NVIDIA is finally going to allow users the choice to enable or disable V-Sync when your game render rate exceeds the maximum refresh rate of the G-Sync monitor it is attached to.
One of the complaints about G-Sync has been that it is restrictive on the high side of the VRR window for its monitors. While FreeSync allowed you to selectively enable or disable V-Sync when your frame rate goes above the maximum refresh rate, G-Sync was forcing users into a V-Sync enabled state. The reasoning from NVIDIA was that allowing for horizontal tearing of any kind with G-Sync enabled would ruin the experience and/or damage the technology's reputation. But now, while the default will still be to keep V-Sync on, gamers will be able to manually set the V-Sync mode to off with a G-Sync monitor.
Why is this useful? Many gamers believe that a drawback to V-Sync enabled gaming is the added latency of waiting for a monitor to refresh before drawing a frame that might be ready to be shown to the user immediately. G-Sync fixes this from frame rates of 1 FPS to the maximum refresh of the G-Sync monitor (144 FPS, 75 FPS, 60 FPS) but now rather than be stuck with tear-free, but latency-added V-Sync when gaming over the max refresh, you'll be able to play with tearing on the screen, but lower input latency. This could be especially useful for gamers using 60 Hz G-Sync monitors with 4K resolutions.
Oh, actually one more thing: you'll now be able to enable ULMB (ultra low motion blur) mode in the driver as well without requiring entry into your display's OSD.
NVIDIA is also officially announcing G-Sync for notebooks at Computex. More on that in this story!

If you remember back to January of this year, Allyn and posted an article that confirmed the existence of a mobile variant of G-Sync thanks to a leaked driver and an ASUS G751 notebook. Rumors and speculation floated around the Internet ether for a few days but we eventually got official word from NVIDIA that G-Sync for notebooks was a real thing and that it would launch "soon." Well we have that day here finally with the beginning of Computex.
G-Sync for notebooks has no clever branding, no "G-Sync Mobile" or anything like that, so discussing it will be a bit more difficult since the technologies are different. Going forward NVIDIA claims that any gaming notebook using NVIDIA GeForce GPUs will be a G-Sync notebook and will support all of the goodness that variable refresh rate gaming provides. This is fantastic news as notebook gaming is often at lower frame rates than you would find on a desktop PC because of lower powered hardware yet comparable (1080p, 1440p) resolution displays.
Of course, as we discovered in our first look at G-Sync for notebooks back in January, the much debated G-Sync module is not required and will not be present on notebooks featuring the variable refresh technology. So what gives? We went over some of this before, but it deserves to be detailed again.
NVIDIA uses the diagram above to demonstrate the complication of the previous headaches presented by the monitor and GPU communication path before G-Sync was released. You had three different components: the GPU, the monitor scalar and the monitor panel that all needed to work together if VRR was going to become a high quality addition to the game ecosystem.
NVIDIA's answer was to take over all aspects of the pathway for pixels from the GPU to the eyeball, creating the G-Sync module and helping OEMs to hand pick the best panels that would work with VRR technology. This helped NVIDIA make sure it could do things to improve the user experience such as implementing an algorithmic low-frame-rate, frame-doubling capability to maintain smooth and tear-free gaming at frame rates under the panels physical limitations. It also allows them to tune the G-Sync module to the specific panel to help with ghosting and implemention variable overdrive logic.
All of this is required because of the incredible amount of variability in the monitor and panel markets today.
But with notebooks, NVIDIA argues, there is no variability at all to deal with. The notebook OEM gets to handpick the panel and the GPU directly interfaces with the screen instead of passing through a scalar chip. (Note that some desktop monitors like the ever popular Dell 3007WFP did this as well.) There is no other piece of logic in the way attempting to enforce a fixed refresh rate. Because of that direct connection, the GPU is able to control the data passing between it and the display without any other logic working in the middle. This makes implementing VRR technology much more simple and helps with quality control because NVIDIA can validate the panels with the OEMs.
As I mentioned above, going forward, all new notebooks using GTX graphics will be G-Sync notebooks and that should solidify NVIDIA's dominance in the mobile gaming market. NVIDIA will be picking the panels, and tuning the driver for them specifically, to implement anti-ghosting technology (like what exists on the G-Sync module today) and low frame rate doubling. NVIDIA also claims that the world's first 75 Hz notebook panels will ship with GeForce GTX and will be G-Sync enabled this summer - something I am definitely looking forward to trying out myself.
Though it wasn't mentioned, I am hopeful that NVIDIA will continue to allow users the ability to disable V-Sync at frame rates above the maximum refresh of these notebook panels. With most of them limited to 60 Hz (but this applies to 75 Hz as well) the most demanding gamers are going to want that same promise of minimal latency.
At Computex we'll see a handful of models announced with G-Sync up and running. It should be no surprise of course to see the ASUS G751 with the GeForce GTX 980M GPU on this list as it was the model we used in our leaked driver testing back in January. MSI will also launch the GT72 G with a 1080p G-Sync ready display and GTX 980M/970M GPU option. Gigabyte will have a pair of notebooks: the Aorus X7 Pro-SYNC with GTX 970M SLI and a 1080p screen as well as the Aorus X5 with a pair of GTX 965M in SLI and a 3K resolution (2560x1440) screen.
This move is great for gamers and I am eager to see what the resulting experience is for users that pick up these machines. I have long been known as a proponent of variable refresh displays and getting access to that technology on your notebook is a victory for NVIDIA's team.
LG Australia published a product page for their LG 27MU67 monitor, which the rest of the company doesn't seem to acknowledge the existence of. It is still online, even after three days worth of time that someone could have used to pull the plug. This one is interesting for a variety of reasons: it's 4K, it's IPS, and it supports AMD FreeSync. It is also relatively cheap for that combination, being listed at $799 AUD RRP.
Some websites have converted that to ~$610 to $620 USD, but it might even be less than that. Australian prices are often listed with their federal tax rolled in, which would yield a price that is inflated about 10%. It is possible, though maybe wishful thinking, that this monitor could retail in the ~$500 to $550 price range for the United States (if it even comes to North America). Again, this is a 4K, IPS, FreeSync panel.
Very little is posted on LG's website and thus it is hard to tell how good of an IPS panel this is. It is listed as 99% SRGB coverage, which is good for typical video but not the best if you are working on printed content, such as magazine illustrations. On the other hand, this is a gaming panel, not a professional one. Update (May 29, 2015): It also has 10-bit (per channel) color. It sounds like it is true 10-bit, not just a look-up table, but I should note that it doesn't explicitly say that.
Again, pricing and availability is up in the air, because this is not an official announcement. It is listed to launch in Australia for $799 AUD, though.
Ryan wasn't the only one to test BenQ's XL2730Z 27-in 2560x1440 144 Hz FreeSync Monitor, The Tech Report also had a chance to test one, as well as talk to NVIDIA's Tom Petersen about their competing technology. They also had a chance to discuss FreeSync in general with AMD's David Glen who is one of the engineers behind FreeSync. Their benchmarks and overall impression of the displays capabilities and FreeSync in general are a major portion of the review but the discussion with the two company representatives makes for even more interesting reading.
"AMD's FreeSync is here, personified in BenQ's XL2730Z monitor. We've gone deep into the display's performance and smoothness, with direct comparisons to G-Sync using 240-fps video. Here's what we found."
