The staff of Rtings has embarked upon their own in-house testing of G-SYNC compatibility with FreeSync monitors (introduced with GeForce driver 417.71), and have released a video to introduce this new project:
While their choice of NVIDIA's Pendulum demo might be up for debate (since let's face it, any time NVIDIA anything is used to test, well, anything, there will always be a conspiracy theory) they have made some noteworthy observations about their experience vs. an AMD FX 580 with the same monitors. Still, as they point out in the article, "This test is by no means exhaustive, and your results may vary depending on the specific games you are playing, and your specific graphics card."
"We test FreeSync on a custom built PC, with an NVIDIA GTX 1060 6GB. Each monitor is connected via DisplayPort, as NVIDIA's FreeSync implementation does not currently work over HDMI. We use NVIDIA's Pendulum G-SYNC demo to test for tearing, stuttering, screen blanking, and other artifacts. We start at the monitor's standard refresh rate, and gradually decrease the sliders until we could see any issues. From there, we gradually increase the sliders until we start seeing tearing or other issues. The results of both of these tests give us the effective variable refresh rate range. We repeat the test at least twice to confirm our findings.
We use the results of this test to subjectively assign a result, based on how well the monitor supports NVIDIA's FreeSync implementation. The possible results are:
- Yes, NVIDIA Certified: This is reserved for monitors that are certified by NVIDIA as being compatible with NVIDIA FreeSync.
- Yes, Native: This is used to differentiate between monitors that support NVIDIA G-SYNC, instead of NVIDIA FreeSync.
- Yes: These monitors are confirmed by us to support FreeSync with no major issues, but are not certified by NVIDIA.
- Partial: These monitors at least partially support FreeSync, but we experienced some issues during testing. See the review for details of these issues.
- No: These monitors either do not support FreeSync at all, or are unusable with FreeSync enabled."
There are currently 25 test results available to help out with your variable refresh-rate monitor selections for use on NVIDIA hardware.

ASUS has their most advanced HDR monitor so far on display at CES 2019, and the ProArt PA32UCX combines a 4K resolution panel with a mini-LED backlighting system offering a whopping 1000 individual lighting zones. Another advantage of the powerful backlighting system is overall brightness, and this can reach a maximum of 1200 nits and exceeds VESA DisplayHDR 1000 requirements.
The very best LED-backlit LCDs employ a technology called full-array local dimming to improve their contrast ratios. The LEDs are arranged in zones, with each zone corresponding to part of the screen, and dimming individual LEDs makes it possible to display an image with bright and dark areas while preserving detail in both.
Our ProArt PA32UCX expounds on this technology with Mini LEDs. These physically smaller LEDs are packed in more densely, which increases the granularity of our brightness control. Less space between the LEDs means small details, like a white cursor on a black background, can be illuminated more precisely. The halo effect that’s common with coarser LED arrays normally manifests as light bleed around bright points, but that’s minimized when there’s a higher number of smaller LEDs.
The ProArt PA32UCX packs 1,000 zones into its 32” form factor, compared to other monitors that use 384 local dimming zones. This is no small achievement, and we had to work closely with the panel and scaler manufacturers on a custom design for controlling all those lighting zones. This technology didn’t exist before, and it took months of testing different proposed solutions before it could be perfected. As a result, the PA32UCX is one-of-a-kind. It offers 1,200 nits of luminance and offers improved whiteness and color uniformity compared to larger OLED panels.
The ProArt PA32UCX, which supports the HDR10 standard, also offers 97% DCI-P3 and 89% Rec. 2020 color space coverage, connecting via USB Type-C as well as the conventional DisplayPort and HDMI 2.0. Pricing and availability have not been announced.

Lenovo has added two monitors to their Legion line of gaming devices.
The Lenovo Legion Y44w is a 43.4” gaming display. Most of that size is horizontal, however, because it has a 32:10 aspect ratio. If you have ever used a 1920x1200 monitor, which was the PC equivalent of 1080p while PC manufacturers believed that 16:9 was too wide so they settled on 16:10 for the Windows Vista era, then you should imagine two of them side-by-side in a single monitor. In fact, the Y44w supports two separate video inputs if you wish to split the monitor down the middle into two side-by-side 1920x1200 displays. It can also operate as a single, 3840x1200 display, of course. This resolution is a little over half of a 4K panel, so it should be easier for second-tier GPUs to feed.
Beyond the resolution, the color gamut is listed as “99% sRGB, BT.709, DCI-P3” and it is certified as VESA HDR400. If the slide deck is correct and it can do 99% DCI-P3 at HDR400, then it should have an amazing picture. It can also do 144 Hz with FreeSync 2, so you do not need to compromise refresh rate to get those beautiful colors. The also have an optional speaker from Harman Kardon that can be attached to the display.
The Lenovo Legion Y44w will be available in April 2019 for $1199.99 USD.
Lenovo also announced the Legion Y27gq gaming monitor. This one is a standard 16:9, 1440p, TN panel that can be driven up to 240 Hz. It supports G-Sync, but not HDR. Despite not supporting HDR, it still covers 90% of DCI-P3, which is quite wide for a TN panel. Lenovo is listing it as an “eSport gaming monitor”… so you can probably guess that high refresh rate and G-Sync are the focus.
If you gotta go fast, then the Lenovo Legion Y27gq is available in April 2019 for $999.99 USD.
BenQ EW3270U Review
The HDR craze continues to heat up in the PC display market, and while some manufacturers are aiming at the high end of performance and price, BenQ is targeting a much more attainable price point with the recent launch of the EW3270U, a 32-inch 4K HDR display.
The EW3270U touts support for HDR, FreeSync, and both DCI-P3 (95 percent coverage) and sRGB (100 percent) but its relatively low price of $699 means that buyers can expect some compromises. We tested the EW3270U to find out if its performance and limitations were worth the price, and discovered a display with very good color accuracy that may be just what mid-range 4K buyers are looking for.

Ultrawide monitors have become an enormous trend in PC gaming over the last 3-4 years. In late 2014 when LG launched the first PC monitors with a 21:9 aspect ratio, I indeed was a skeptic. To me, it seemed like such a radical new aspect ratio would be wrought with game incompatibility, and wouldn't offer much of an advantage over two monitor setups for productivity.
And in the beginning, this was mostly the case. In 2014, games didn't even enable the option for 21:9 aspect ratio resolutions, and those that did, generally resulted in distorted image and FOV settings.
However, gamers wanted these ultrawide aspect ratio displays, and the game support soon followed. Now, ultrawide monitors are a staple of every monitor manufacturer's product lineup.
What we are looking at today though, is the most intense of all of the ultrawide monitors, the 49" Samsung CHG90. And it just so happens to be one of the first AMD FreeSync 2 displays.
Still in the ultrawide category, the CHG90 moves away from the more traditional 21:9 ultrawide aspect ratio to a wider and squatter 32:9. This aspect ratio allows Samsung to maximize the width of the CHG90 while keeping the display short enough not to engulf your entire wall.
Essentially, you can look at this display as two 27" monitors sitting side-by-side, without the pesky bezel in the middle. Similarly, the resolution of the CHG90 matches the effective resolution of two 1080p monitors sitting next to each other, with a total resolution of 3840x1080.
To achieve such a big display size in a still relatively usable form factor, the CHG90 display features a 1800R curvature. This figure refers to the measurement of the resulting radius that the display would make if it continued to make a full circle. For example, a 3000R display would have less of a curve than a 1800R display.
The curve on the CHG90 isn't quite like any other display we've seen, however. Due to the immense size of the display, the entire panel isn't curved. The curve stops about 6 inches from the edge of either side of the screen.
When PC monitors made the mainstream transition to widescreen aspect ratios in the mid-2000s, many manufacturers opted for resolutions at a 16:10 ratio. My first widescreen displays were a pair of Dell monitors with a 1920x1200 resolution and, as time and technology marched forward, I moved to larger 2560x1600 monitors.
I grew to rely on and appreciate the extra vertical resolution that 16:10 displays offer, but as the production and development of "widescreen" PC monitors matured, it naturally began to merge with the television industry, which had long since settled on a 16:9 aspect ratio. This led to the introduction of PC displays with native resolutions of 1920x1080 and 2560x1440, keeping things simple for activities such as media playback but robbing consumers of pixels in terms of vertical resolution.
I was well-accustomed to my 16:10 monitors when the 16:9 aspect ratio took over the market, and while I initially thought that the 120 or 160 missing rows of pixels wouldn't be missed, I was unfortunately mistaken. Those seemingly insignificant pixels turned out to make a noticeable difference in terms of on-screen productivity real estate, and my 1080p and 1440p displays have always felt cramped as a result.
I was therefore sad to see that the relatively new ultrawide monitor market continued the trend of limited vertical resolutions. Most ultrawides feature a 21:9 aspect ratio with resolutions of 2560x1080 or 3440x1440. While this gives users extra resolution on the sides, it maintains the same limited height options of those ubiquitous 1080p and 1440p displays. The ultrawide form factor is fantastic for movies and games, but while some find them perfectly acceptable for productivity, I still felt cramped.
Thankfully, a new breed of ultrawide monitors is here to save the day. In the second half of 2017, display manufactures such as Dell, Acer, and LG launched 38-inch ultrawide monitors with a 3840x1600 resolution. Just like the how the early ultrawides "stretched" a 1080p or 1440p monitor, the 38-inch versions do the same for my beloved 2560x1600 displays.
The Acer XR382CQK
I've had the opportunity to test one of these new "taller" displays thanks to a review loan from Acer of the XR382CQK, a curved 37.5-inch behemoth. It shares the same glorious 3840x1600 resolution as others in its class, but it also offers some unique features, including a 75Hz refresh rate, USB-C input, and AMD FreeSync support.
Based on my time with the XR382CQK, my hopes for those extra 160 of resolution were fulfilled. The height of the display area felt great for tasks like video editing in Premiere and referencing multiple side-by-side documents and websites, and the gaming experience was just as satisfying. And with its 38-inch size, the display is quite usable at 100 percent scaling.
There's also an unexpected benefit for video content that I hadn't originally considered. I was so focused on regaining that missing vertical resolution that I initially failed to appreciate the jump in horizontal resolution from 3440px to 3840px. This is the same horizontal resolution as the consumer UHD standard, which means that 4K movies in a 21:9 or similar aspect ratio will be viewable in their full size with a 1:1 pixel ratio.
Non-profit standards association VESA has put forth a new open standard called DisplayHDR for defining HDR specifications and performance for PC laptop and desktop LCDs. The new test specification, dubbed Display HDR 1.0, defines a transparent testing methodology and definitions along with specifying three tiers of HDR system performance that will identify displays as being certified for minimum, mid-range, and high-end HDR with their respective badges of DisplayHDR 400, DisplayHDR 600, and DisplayHDR 1000. Consumers will be able to easily identify which panels have HDR and how they stack up.
The new HDR standard was devised by VESA with input from over two dozen of its member companies including major OEMs of displays, panels, graphics cards, CPUs, display drivers, and color calibration providers. DisplayHDR is reportedly a fully open and transparent standard with automated tools that end users can download and run to verify the results for themselves. The standard includes three peak luminance tests, two contrast measurement tests (native and local dimming), color testing and validation of BT.709 and DCI-P3 color gamuts, bit-depth requirement tests (see below), and HDR backlight response time measurements.
DisplayHDR 400 represents the minimum entry-level tier of HDR per the VESA specification and specifies that a LCD display must feature at least 400 nits brightness (both short, local bursts and full screen flashes), 8-bit color depth, HDR-10, and global dimming. VESA notes that many non-HDR displays that advertise as supporting 8-bit colors, it is actually a 6-bit panel that uses a dithering algorithm to achieve a simulated 8-bits. DisplayHDR specifies true 8-bit at a minimum, and for DisplayHDR 600 and DisplayHDR 1000 displays must achieve 10-bit depth using 8-bit panels combined with 2-bit dithering at a minimum.
Display and PC manufacturers have reportedly had their hands on the DisplayHDR test specification for some time now and are working on validating their displays so that they can offer products with the DisplayHDR logos. New product announcements and demonstrations are expected during CES 2018 next month with DisplayHDR compatible products showing up as early as Q1 2018. VESA notes that while DisplayHDR currently only targets LCDs, it hopes to extend the open standard to include OLED displays in the future.
I think this is a good thing as there is a lot of confusing and conflicting advertising out there when it comes to HDR. A vendor neutral specification and badge that can also be independently tested may be just what the display market needs to push HDR into the mainstream.

Acer announced a number of products at their next@acer press event in New York yesterday, but this new monitor might take the cake: a 4K HDR display with a 144 Hz refresh rate. The Predator X27 combined just about every conceivable feature for a gaming monitor and combines it into one product, but don't expect this 27-inch monitor be released at a budget price (pricing has not been announced).
"Acer’s Predator X27 portrays astonishingly vibrant visuals without motion blur thanks to a high 4K (3840x2160) resolution at a 144 Hz refresh rate, a fast 4 ms response time and a 1,000 nit peak brightness. Featuring Acer HDR Ultra technology, it offers the best possible contrast quality of the high dynamic range with advanced LED local dimming in 384 individually-controlled zones that shine light only when and where it is required. It not only delivers a broader, more deeply saturated color gamut, but a luminance range several times greater than that of traditional dynamic range monitors. By dimming the backlight behind parts of the screen displaying black, blacks appear deeper and darker on those parts of the panel, a significant bonus for people who play games with darker scenes."
Acer has posted a video about the Predator X27, imbedded below:
Acer also announced a new curved gaming monitor with the Predator Z271UV, which offers a 1800R curve from its 27-inch display, but for HDR you'll need to stick to the X27. Quantum dot technology is incorporated into both display for wide color, and both feature NVIDIA G-SYNC variable refresh-rate tech featuring ULMB (ultra-low motion blur) along with with Tobii eye-tracking.
"Acer’s Predator Z271UV provides WQHD (2560x1440) resolution on a curved 1800R panel that puts every corner of the screen at the same distance from the gamer’s eyes – this creates more immersive gameplay with a wider field of view and increased perceived area of peripheral vision. It features a ZeroFrame edge-to-edge design perfect for use in multi-monitor setups, and provides spectacular color breadth covering 125% of the sRGB color space. It’s extremely fast with up to a 1 ms (3 ms native) response time that nearly eliminates motion blur and supports overclocking up to 165 Hz."
We await pricing and availability information for both monitors.
