G-SYNC is showing some signs of defeat as today NVIDIA announced that several Adaptive Sync monitors have been tested and rated as G-SYNC compatible. Adaptive Sync is the official VESA technology which is present in AMD's FreeSync monitors and it offers a definitive financial advantage over NVIDIA's G-SYNC as the module required for G-SYNC can add hundreds of dollars to the price.
So far only a dozen monitors out of around 400 tests have been rated as G-SYNC compatible, so don't expect to be mixing your monitors quite yet but it does imply in some cases the extra controller is not required for variable refresh rates with either NVIDIA's or AMD's GPUs. The results of this test give AMD bragging rights for implementing adaptive sync in the most attractive way but this change could hurt GPU sales as users can now opt for an GeForce card paired with a FreeSync display.
Even if your display is not listed in those models, you can try enabling adaptive sync over DisplayPort and see if it works, though your results may vary. Ars Technica lists the models here.
"Besides being unexpected good news for gamers who already own one of these FreeSync monitors, this is also great news for gamers that want to add VRR to their Nvidia graphics card setup without breaking the bank."

While we tend to focus on PC Gaming-oriented displays here at PC Perspective, they don't necessarily represent the highest-end of the PC monitor market. Often professionals working in photography and videography areas have stricter requirements for the displays they use.
Just imagine, if you are mastering video in wide gamut color spaces like DCI-P3 for HDR playback, you need to be assured that the source image on your PC is being accurately represented on your display. While the highest-end production use reference displays that can cost upwards of $20,000, there's a growing market for more modestly priced displays for prosumers that can also provide reasonable assurance of color accuracy.
This is the type of consumer that ASUS targets with their "ProArt" lineup. Today, we are taking a look at the ASUS ProArt PA32UC, a factory-calibrated 32" 3840x2160 display capable of 99.5% AdobeRGB coverage.

Yes, this is the product Ryan mentioned, a curved 37.5" IPS adaptive sync display from Acer. As opposed to yesterday, today Quad HD refers to a 3840x1600 2300R curve ultra wide screen resolution, making shopping for a monitor even easier, before you even try to type in the model number. It supports Adaptive Sync, with a refresh rate that tops out at 75Hz; sorry G-SYNC fans.
As with yesterdays model it has as slimmed down bezel, called ZeroFrame in this case. It supports HDMI 1.3 10-bit colour, or at least states it offers 1.07 billion colours as well as a 100,000,000:1 contrast ratio and 300 nit brightness. The monitor also includes DTS Sound speakers and has a USB 3.0 Type-C port. You can read a bit more about it here.

The HDMI Forum has introduced an update to the HDMI specification, bringing the video standard to version 2.1. The updated specification, along with its accompanying new "48G" (48 Gbps) HDMI cable, brings support for higher resolutions refresh rates, and color spaces along with new features such as dynamic HDR, a variable refresh rate "Game Mode VRR", and eARC for audio device detection and object oriented audio (e.g. Dolby Atmos).
Specifically, HDMI 2.1 adds support for 8K resolutions at up to 60 Hz and 4K at up to 120 Hz along with HDR (high dynamic range). The specification is even a bit future looking in that it allegedly supports 10K50/60/100/120 modes! The 8K@60 and 4K@120 (and higher) profiles do require the new 48 Gbps cable though lower resolutions can still get by with the older High Speed cable. The specification also supports BT2020 color spaces with 10, 12, and 16 bits per color component which I expect Ken and Allyn will appreciate.
Perhaps the most interesting new feature though is the Game Mode VRR which appears to be HDMI's take on DisplayPort's Adaptive Sync (which AMD uses for FreeSync). At last year's CES AMD was showing off FreeSync over HDMI (video) with AMD doing FreeSync over HDMI as an extension of the specification. It now appears that HDMI is rolling some manner of that variable refresh technology into the base HDMI 2.1 specification. Variable refresh rates being supported with HDMI is a good thing as it means that future game consoles may see their own FreeSync/G-Sync like variable display output options as I do not see game consoles and living room devices (TVs, receivers, et al) adopting DisplayPort any time soon if only because of the huge install base and foothold HDMI has on that market.
Notably, HDMI 2.1 remains backwards compatible with earlier specifications, cables, and devices based on older HDMI standards including the Ethernet channel and inter-device communication. Existing devices will be able to use HDMI 2.1's 48 Gbps cables but will not be forwards compatible with all of the new features (though partial new feature support might be possible with firmware updates though in no way guaranteed).
The new specification is expected to officially drop in early Q2 2017 at which point it will be available to all HDMI Adopters for testing.
I estimate that, following the compliance testing and device QA, products using the new specification should start shipping as soon as next year (at CES 2018 perhaps!). It is harder to say when graphics cards or game consoles will start supporting the new output though. I would hope that AMD and NVIDIA would be able to sneak it in before Vega and Volta based cards launch respectively but the timing may not have lined up like that. And on the game console side of things, Microsoft and Sony have already launched their revised consoles this year save Scorpio so it might be awhile before they sport variable refresh. Perhaps JoshTekk and the crew will have some thoughts on the podcast next week!
What are your thoughts on HDMI 2.1? Will it lay the groundwork for interesting displays and better living room gaming?

Tagged: TN, ips, g-sync, AOC, AGON, AG271QX, AG271QG, adaptive sync, 1440p
AOC has announced two new 27" 1440p gaming monitors specifically designed to minimize input lag and to support the higher refresh rates than many gamers now demand. The model numbers are similiar but the monitors themselves are very different and each wears a red or green stripe proudly.
The AG271QX is a TN panel with a 1ms response time and a top refresh rate of 144Hz, it supports Adaptive Sync for those using AMD GPUs. This panel is great for those who place zero lag ahead of colour reproduction and viewing angle. It is to retail at $600.
The AG271QG is an IPS panel with four times the response time, still a mere 4ms, a top refresh rate of 165Hz and support for G-SYNC. This one should have a better colour gamut and truer blacks for those more concerned with fashion over function. You should expect to see this model at $800.
Full PR below the specs.

ASUS has announced three new monitors from their Republic of Gamers division, all of which feature Adaptive-Sync variable refresh rate displays.
ASUS ROG MG28UQ
The monitors include a 28-inch model (MG28UQ), and a pair of 24-inch displays (MG248Q, MG24UQ). Looking first at the MG28UQ, which is a 28-inch, UHD/4K (3840x2160) display featuring a 1ms response time. Inputs include DisplayPort (1.2), one HDMI 2.0, and two HDMI 1.4 ports.
One of the 24-inch displays, the MG24UQ, is also UHD/4K but features an IPS display (and consequently loses the 1ms response time of the 28-inch version).
ASUS ROG MG24UQ
Finally there is the 24-inch MG248Q, which offers a high 144 Hz refresh rate and 1ms response from its TN panel, but this model offers only FHD (1920x1080) resolution - though still adequate for gaming (especially at higher detail settings) depending on your preferences.
ASUS ROG MG248Q
As far as availability goes, ASUS states "ASUS MG28UQ and MG24UQ are available immediately worldwide. MG248Q will be available in April 2016", though pricing was not announced.

Two 4K monitors were announced by ASUS at the show. Both use VESA Adaptive-Sync for variable refresh rate (VRR) gaming, which means they are compatible with AMD FreeSync, but not NVIDIA G-Sync. If you want to use the latter VRR standard, then you would be more interested in the ROG Swift PG348Q monitor that was announced in September. There was talk that Intel would be implementing a VRR format VESA Adaptive-Sync in a future GPU.
If you're still here, then you either don't care about variable refresh, or you are looking for an AMD-compatible one. The first one is the 24-inch MG24UQ. It is based on an IPS panel, which are used for vibrant, precise colors and wide viewing angles. They tend to be a little slower than traditional “gaming” panels, but that is so low for the last couple of years that IPS is considered a pure upgrade. The second monitor, the 28-inch MG28UQ, is not IPS, though.
Again, no pricing or availability yet as it varies by region.

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.

Tagged: LG, 34um67, ultrawide, 21:9, CES, ces 2015, freesync, adaptive sync
Let the variable refresh rate monitor battle begin! This week LG has announced a gaming-specific 21:9 aspect ratio monitor that features support for AMD's FreeSync variable refresh rate technology. LG joins Samsung as monitor vendors that have officially thrown in hats with the AMD-backed and VESA standard Adaptive Sync technology rather than NVIDIA's G-Sync (or maybe in addition to).
The new 34UM67 is a flat, 34-in 21:9 aspect ratio display; a style that is becoming increasing popular among enthusiast and gamers as they offer expanding views in some games without the need to use multiple monitors in a Eyefinity or Surround configuration. LG has not announced the resolution yet but I assume that since they aren't bragging about it openly, that we are looking at a 2560x1080 screen rather than 3440x1440. Still, coupling that resolution with support for a variable refresh technology should provide an impressive gaming experience.
Here is what the official press release has to say about the new LG 34UM67 being shown next week at CES:
LG's UltraWide Gaming Monitor (34UM67) is the company's first 21:9 monitor specifically developed for graphics-intensive gaming. AMD's FreeSync technology eliminates the screen tearing that occurs when the monitor and graphics card are out of sync. Furthermore FreeSync technology guarantees the smoothest and most seamless gaming experience, generating fluid motion without any loss of frame rate.
"AMD FreeSync technology is an innovative monitor technology, based on free and open industry standards, to eliminate the tearing and stuttering that has plagued PC gaming for 30 years," said Roy Taylor, corporate vice president of ISV/IHV Partner Group, AMD. "We are pleased that LG Electronics stands with us with truly exciting AMD FreeSync-ready displays like the LG UltraWide Gaming Monitor."
The 34UM67 also has an exceptional UltraWide field of view (FOV), allowing gamers to gain the upper hand by revealing hidden spaces that were invisible on regular 16:9 monitors. The monitor's Black Stabilizer illuminates dark scenes and helps to clearly define the deep black areas where objects and enemies could be hidden. The Dynamic Action Sync mode minimizes input lag, enhancing users' real time gaming experience. Many popular games such as Battlefield 4, World of Warcraft and ArcheAge currently support 21:9 resolution with more games expected to support this resolution in the future.
Support for 21:9 resolutions is still spotty in most PC titles and can result in the same kind of FOV scaling issues we see with Eyefinity. More games are including direct support for these monitors and hopefully 2015 will see a focus on that with each game release.
I still have a lot of questions about AMD's FreeSync technology and how it will stand up to the effectiveness of NVIDIA G-Sync, but I am eager to see it first hand. CES will provide the first opportunity for us but we will obviously need extended time with panels in our offices to make a final decision.
