When we mention 4K monitors, they typically have a resolution of 3840x2160. Digital Cinema 4K adds an extra 256 pixels horizontally, yielding 4096x2160 (an aspect ratio between 17:9 and 19:10). LG Electronics has just released a monitor at this resolution for video and graphics professionals, and its feature set is strongly focused on that market.
First, with a Digital Cinema 4K resolution, the monitor is capable of previewing content in that resolution without scaling or cropping. Alternatively, software could preview consumer 4K ("UltraHD") and have a little leftover room for user interface elements.
What really sets this apart from other monitors is its color space features. This is an actual IPS panel, providing wide viewing angles, and it supports 10-bit color input for smoother gradients. Its color space is large, too. Beyond sRGB, it also covers 99.5% of the AdobeRGB color space and 97% of the DCI-P3 gamut. LG even has a mode that splits the monitor into two, one side in AdobeRGB and the other in sRGB. This is intended for artists and publishers to see content both in the color space of professional printers (AdobeRGB) and websites on consumer displays (sRGB).
While I believe this panel is rated at 60 Hz, it does not explicitly say that anywhere (that I found). I emailed LG for clarification and I will update if/when they reply. Update (Nov 4 @ 7:45pm EST): Still no word from LG, but one reader pointed me to an Overclockers UK product page that claims 60 Hz over DisplayPort and Mini DisplayPort. A second reader claims to own one of these monitors, which is running at 60Hz over Mini DisplayPort. It sounds like it supports 60Hz SST.
If it is a 60 Hz panel, this is an interesting, 31-inch display, especially at an MSRP of $1399.99. It undercuts competitors, like the Dell Ultrasharp 32, by over a thousand dollars. The LG 31MU97 is available now at a few online retailers.
Here they come - the G-Sync monitors are finally arriving at our doors! A little over a month ago we got to review the ASUS ROG Swift PG278Q, a 2560x1440 144 Hz monitor that was the first retail-ready display to bring NVIDIA's variable refresh technology to consumers. It was a great first option with a high refresh rate along with support for ULMB (ultra low motion blur) technology, giving users a shot at either option.
Today we are taking a look at our second G-Sync monitor that will hit streets sometime in mid-October with an identical $799 price point. The Acer XB280HK is a 28-in 4K monitor with a maximum refresh rate of 60 Hz and of course, support for NVIDIA G-Sync.
The Acer XB280HK, first announced at Computex in June, is the first 4K monitor on the market to be announced with support for variable refresh. It isn't that far behind the first low-cost 4K monitors to hit the market, period: the ASUS PB287Q and the Samsung U28D590D both shipped in May of 2014 with very similar feature sets, minus G-Sync. I discussed much of the general usability benefits (and issues) that arose when using a consumer 4K panel with Windows 8.1 in those reviews, so you'll want to be sure you read up on that in addition to the discussion of 4K + G-Sync we'll have today.
While we dive into the specifics on the Acer XB280HK monitor today, I will skip over most of the discussion about G-Sync, how it works and why we want it. In our ASUS PG278Q review I had a good, concise discussion on the technical background of NVIDIA G-Sync technology and how it improves gaming.
The idea of G-Sync is pretty easy to understand, though the implementation method can get a bit more hairy. G-Sync introduces a variable refresh rate to a monitor, allowing the display to refresh at wide range of rates rather than at fixed intervals. More importantly, rather than the monitor dictating what rate this refresh occurs at to the PC, the graphics now tells the monitor when to refresh in a properly configured G-Sync setup. This allows a monitor to match the refresh rate of the screen to the draw rate of the game being played (frames per second) and that simple change drastically improves the gaming experience for several reasons.

Tagged: esports, asus, vg248qe
I am a little torn about the term "eSports". Yes, I've used it. It is the accepted name. According to the definition, it mostly fits its role. Grammar and language are also fluid concepts, too. They can mean different things as time passes. I guess my real problem is that it attempts to snuggle up to "sports" for acceptance, but maintains a single-letter divider (unlike golf and, to some extent, curling). In my opinion, it is either a sport or it is something else entirely (a game, maybe?).
Apparently they support StarCraft, too.
Also, it should be considered legitimate. Spectator sports are for entertainment, and "eSports" are entertaining to watch. Sure, it is not for everyone -- but neither is any other sport.
Two organizations that do consider it legitimate is ASUS and Robert Morris University (RMU). The college has recently announced scholarships for the top League of Legends players. After all, a sports scholarship is just an advertisement expense from the university's view. That applies to any sports scholarship. The point is to lure students to your campus and spectators to sporting events. Consistent winnings and great players gets your name out there on both fronts. There is nothing wrong with that, as long as they uphold a high standard of education, too.
Today's news is that ASUS partnered with RMU to provide "over three dozen" monitors to the university. Specifically, the VG248QE 24-inch, 144Hz display. This is almost $10,000 USD of hardware at current retail price. The press release is unclear whether ASUS donated the panels, or if they were sold at a discount. I reached out to the university over Twitter for clarification.
Honestly, I find this interesting and an innovative extension on old practices.

Tagged: Oculus, VR, crescent bay, oculus connect
As they progress toward a consumer product, Oculus announced another prototype at their Oculus Connect developer conference. Dubbed Crescent Bay, the headset contains a new display, with a higher refresh rate and higher resolution, better optics, and 360-degree head tracking. It is also lighter and includes built-in speakers.
Of course, these features were not quantified with hard specifications.
Brendan Iribe, CEO of Oculus, stressed that this is not the consumer product yet. He claims that this is an increase over DK2 that is equivalent to the increase DK2 saw over the original Oculus Rift. It is not all about hardware, though. This company is engaged in hardware and software, video and audio. This should make sense considering their early acquisition of John Carmack and hundreds of other engineers. They, rightly, see themselves as a platform and, while they see game engines as necessary for VR, due to the ability to reposition the camera in milliseconds of notice, compared to film's never, they are not limiting themselves to just "games" (but yes they consider it a big part of it).
Honestly, months ago, I was sitting at my desk with its five monitors, each with bits of news posts, chats, reference material, and maybe a StarCraft tournament live stream, and Oculus was being discussed. I started to wonder if monitors, especially multiple displays, are just an approximation -- our current best effort -- of how to receive video cues from a PC. I could see a VR platform take on entertainment and even productivity with its infinite, virtual environments.
Currently, there is not even a hint about pricing and availability (as far as I found).

Tagged: amd, freesync, DisplayPort, adaptive sync
MStar, Novatek, and Realtek, three vendors of scaler units for use in displays, have announced support for AMD's FreeSync. Specifically, for the Q1'15 line of monitors, these partners will provide scaler chips that use DisplayPort Adaptive-Sync and, when paired with a compatible AMD GPU, will support FreeSync.
The press release claims that these scalar chips will either support 1080p and 1440p monitors that are up to 144Hz, or drive 4K displays that are up to 60Hz. While this is promising, at least compared to the selection at G-Sync's launch a year earlier, it does not mean that this variety of monitors will be available -- just that internal components will be available for interested display vendors. Also, it means that there are probably interested display vendors.
AMD and partners "intend to reveal" displays via a "media review program" in Q1. This is a little later than what we expected from Richard Huddy's "next month" statements, but it is possible that "Sampling" and "Media Review Program" are two different events. Even if it is "late", this is the sort of thing that is forgivable to me (missing a few months while relying on a standards body and several, independent companies).

Tagged: Acer XB270H, XB280HK, 4k, g-sync
The Acer XB280HK is a 28" 4K G-SYNC display which will launch next month at expected price of US$799 or $849.99CDN. The XB270H is a 27" 1080p display also with G-SYNC support and is currently available at $599USD or $649CDN. As both are rated with a 1ms response time it is likely these are backlit TN panels but with the recent advances in TN panels the viewing angles should be much better than the original generation.
SAN JOSE, Calif., Sept. 18, 2014 – Acer America is bringing its new XBO series gaming displays featuring NVIDIA G-SYNC technology to gaming enthusiasts in North America. This cutting-edge line delivers significant performance advantages that infuse gaming with incredibly smooth, realistic and responsive visuals, elevating game play to a new level of stunning realism.
The two XBO series display models for North America include the Acer XB280HK boasting a 28-inch 4K2K Ultra HD (3840 x 2160) display with a @60Hz refresh rate and the Acer XB270H with a 27-inch screen and a maximum Full HD 1080p @ 144Hz resolution. Both models provide a quick 1ms response time, further enhancing in-game performance. They also feature revolutionary NVIDIA G-SYNC technology, comfortable ergonomics and excellent connectivity.
“We’re excited to bring these first-rate gaming displays to gamers in the United States and Canada,” said Ronald Lau, Acer America business manager. “The incredibly sharp and smooth images provided by NVIDIA G-SYNC technology are sure to thrill the most avid gamers. Combined with Acer’s highly flexibly ergonomic stand, non-glare ComfyView panel and low dimming technology, users are assured long hours of both comfortable and visually stunning game play.”
NVIDIA G-SYNC: Picture-Perfect Visuals
NVIDIA G-SYNC technology ensures that every frame rendered by the GPU is perfectly portrayed by synchronizing the monitor’s refresh rates to the GPU in a GeForce GTX-powered PC. This breakthrough technology eliminates screen tearing and minimizes display stutter and input lag to deliver a smooth, fast and breathtaking gaming experience on the hottest PC gaming titles. Scenes appear instantly, objects look visually sharp, and gameplay is more responsive to provide faster reaction times, giving gamers a competitive edge.
“NVIDIA G-SYNC technology dramatically improves the way gamers see their games, by delivering images that are fast, sharp and stutter-free,” said Tom Petersen, distinguished engineer at NVIDIA. “This is the way games were meant to be played, and gamers will absolutely love these new Acer XBO monitors.”
By making gaming as comfortable as possible, the XBO series monitors help extend game time with three Acer innovations. Acer flicker-less technology reduces eye strain via a stable power supply that eliminates screen flicker. Its low dimming technology provides users the ability to adjust brightness down to 15 percent in low-light environments and Acer ComfyView non-glare screen reduces reflection for clearer viewing, a significant benefit for gamers.
A flexible, multi-function ErgoStand extends a wide range of options for maximum comfort and viewing perspectives. For finding the best angle, the screen tilts from -5 to -35 degrees and the height can be raised by up to 5.9 inches. In addition, the base rotates 120 degrees from left to right for easy screen sharing during game play and collaboration with others. Plus, the screen pivots from horizontal to vertical to accommodate two entirely different gaming scenarios.
Both new XBO series monitors deliver wide viewing angles up to 170 degrees horizontal and up to 160 degrees vertical. The Acer XB280HK delivers 1.07 billion colors and the Acer XB270HL provides 16.7 million colors, while both offer a native contrast ratio of 1000:1, a 300 nits brightness and a 72 percent NTSC color saturation, a combination that delivers exceptionally vibrant, detailed and high-quality imagery.
The displays come with DisplayPort as well as high-speed USB 3.0 ports (1 up, 4 down) that are located on the side and down of screen for easily connecting a mouse, keyboard, gaming headset, joystick and other peripherals. One of the USB ports is equipped for battery charging.
EPEAT Gold registered, the highest level of EPEAT registration available, the displays meet all of EPEAT’s required criteria and at least 75 percent of EPEAT’s optional criteria. They’re also mercury-free and LED-backlit, which reduces energy costs by consuming less power than standard CCFL-backlit displays. ENERGY STAR 6.0 and TCO 6.0 qualified, they adhere to strict environmental, performance and ergonomic design standards.

Tagged: displayport 1.3, freesync, 5k, vesa, dockport
It is official, DisplayPort 1.3 has finished VESA approval and should be hitting the streets in the near future. Freesync support came with 1.2a which is why it was not mentioned, however DockPort has been enhanced with the higher 8.1 Gbps link rate for each of the four lanes present which means you can support a 4k monitor using two of those lanes, leaving the other two available for USB, audio or even power.
This also means that 4k and even 5k monitors can function over a single DisplayPort 1.3 cable without any compression and with the use of VESA's Coordinated Video Timing you can have a pair of 4k monitors function in multi-monitor mode ... assuming you have the graphical horsepower to run 7680 x 2160. It is rather impressive to see this jump to 32.4 Gbps combined link rate that can deliver 25.92 Gbps of uncompressed video data.
Newark, CA (15 September 2014) The Video Electronics Standards Association (VESA) announced the release of the DisplayPort 1.3 audio / video (A/V) standard. An update to the widely used DisplayPort 1.2a standard, this latest version increases the maximum link bandwidth to 32.4 Gbps, with each of four lanes running at a link rate of 8.1 Gbps/lane a 50% increase from the previous version of the DisplayPort standard. Allowing for transport overhead, DisplayPort's 32.4 Gbps combined link rate delivers 25.92 Gbps of uncompressed video data.
The increased bandwidth enables higher resolution monitors, including recently announced 5K monitors (with pixel resolutions of 5120 x 2880) using a single DisplayPort cable without the use of compression. It will also enable higher resolutions when driving multiple monitors through a single connection using DisplayPort's Multi-Stream feature, such as the use of two 4K UHD monitors, each with a pixel resolution of 3840 x 2160, when using VESA Coordinated Video Timing.
DisplayPort 1.3 continues to support video conversion to VGA, DVI and HDMI. DisplayPort 1.3 adds support for HDCP 2.2 and HDMI 2.0 with CEC (Consumer Electronics Control), which enhances DisplayPort's utility for television applications, including 4K video with copy protection. The new standard adds support for the 4:2:0 pixel structure, a video format commonly used on consumer digital television interfaces, which enables support for future 8K x 4K displays.
DisplayPort 1.3 also enhances DisplayPort's value for multi-function interfaces that combine data transport, A/V transport and other capabilities on a single cable. It further refines protocols that enable DisplayPort to share a single cable with other data types. With its higher 8.1 Gbps per-lane link rate, DisplayPort 1.3 can support a single UHD monitor with 60Hz refresh and 24-bit color over two lanes, while assigning the remaining two lanes to increase capacity for alternate data types, such as SuperSpeed USB data, as allowed in DockPort. DisplayPort is the A/V transport standard used by DockPort, Thunderbolt and other wired and wireless multi-function interface standards.
While becoming a mainstream video standard, DisplayPort continues to be at the cutting edge of A/V transport, said VESA Board of Directors Chair Alan Kobayashi, Fellow & Executive R&D Management for DisplayPort Group at MegaChips Technology America. These new enhancements to DisplayPort will facilitate both higher resolution displays, as well as easier integration of DisplayPort into multi-protocol data transports, which will satisfy consumer's desire for simplicity and ease-of-use.
The DisplayPort standard is offered to VESA members without any license fee. For more information about DisplayPort, please visit http://www.displayport.org or connect with us on YouTube.

Tagged: dell, 5120 x 2880, 5k, UltraSharp 27 Ultra HD 5K
That's right, Dell is releasing the Dell UltraSharp 27 Ultra HD 5K Monitor with a resolution of 5120 x 2880 for a mere $2500 just in time for Christmas. That is just under 6.5 million more pixels than 4k which is an impressive jump and should look very interesting on a 27" display!
While we may not have TV content to justify this resolution gamers with extreme GPUs should be able to take advantage of it as soon as it is released. You will probably be able to turn your anti-aliasing settings down with pixels that small. It will also have 16W integrated Harmon Kardon speakers and quite likely a few USB ports. Surround setups are going to need every PCIe lane you can toss at it though, good thing those 295X2's are on sale right now! They've also added some information about their 4K displays here.

Earlier today we had NVIDIA's Tom Petersen in studio to discuss the retail availability of G-Sync monitors as well as to get hands on with a set of three ASUS ROG Swift PG278Q monitors running in G-Sync Surround! It was truly an impressive sight and if you missed any of it, you can catch the entire replay right here.
Even if seeing the ASUS PG278Q monitor again doesn't interest you (we have our full review of the monitor right here), you won't want to miss the very detailed Q&A that occurs, answering quite a few reader questions about the technology. Covered items include:
- Potential added latency of G-Sync
- Future needs for multiple DP connections on GeForce GPUs
- Upcoming 4K and 1080p G-Sync panels
- Can G-Sync Surround work through an MST Hub?
- What happens to G-Sync when the frame rate exceeds the panel refresh rate? Or drops below minimum refresh rate?
- What does that memory on the G-Sync module actually do??
- A demo of the new NVIDIA SHIELD Tablet capabilities
- A whole lot more!
Another big thank you to NVIDIA and Tom Petersen for stopping out our way and for spending the time to discuss these topics with our readers. Stay tuned here at PC Perspective as we will have more thoughts and reactions to G-Sync Surround very soon!!

Tomorrow at 12pm EDT / 9am PDT, NVIDIA's Tom Petersen will be stopping by the PC Perspective office to discuss some topics of interest. There has been no lack of topics floating around the world of graphics card, displays, refresh rates and tablets recently and I expect the show tomorrow to be incredibly interesting and educational.
On hand we'll be doing demonstrations of G-Sync Surround (3 panels!) with the ASUS ROG Swift PG278Q display (our review here) and also show off the SHIELD Tablet (we have a review of that too) with some multiplayer action. If you thought the experience with a single G-Sync monitor was impressive, you will want to hear what a set of three of them can be like.
NVIDIA Live Stream with Tom Petersen
9am PT / 12pm ET - August 22nd
The topic list is going to include (but not limited to):
- ASUS PG278Q G-Sync monitor
- G-Sync availability and pricing
- G-Sync Surround setup, use and requirements
- Technical issues surrounding G-Sync: latency, buffers, etc.
- Comparisons of G-Sync to Adaptive Sync
- SHIELD Tablet game play
But we want your questions! Do you have burning issues that you think need to be addressed by Tom and the NVIDIA team about G-Sync, FreeSync, GameWorks, Tegra, tablets, GPUs and more? Nothing is off limits here, though obviously Tom may be cagey on future announcements. Please use the comments section on this news post below (registration not required) to ask your questions and we can organize them before the event tomorrow. We MIGHT even be able to come up with a couple of prizes to giveaway for live viewers as well...
See you tomorrow!!
