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 their PE320QK professional display several months ago, but it is now available. Before we get too far into the specifications, and there are some things that need to be discussed about them, the MSRP is $1199.99 USD, but it’s apparently above that in practice. The third-party seller on Newegg, TELeasy, is currently sold out at a listed price of $1330.17.
As for the specifications? Here’s where it gets interesting. First, the press release states that the PE320QK can do 130% of sRGB. This is nonsense. sRGB is a color space that you calibrate down into. You cannot cover more than it, because otherwise you wouldn’t be calibrated to it. Either your potential color space covers the whole gamut, or it doesn’t. It doesn’t matter what else it covers, just that it doesn’t miss anything inside the fenced-in area that the spec cares about. In fact, saying that it’s 130% makes me question whether it will end up less than 100% of the post-calibration gamut.
That’s not a concern that you want to have with a $1200 monitor.
The other issue is with the contrast ratio, although this is a number that every display manufacturer, especially TVs, screw with. It is listed as 100,000,000 : 1. Yeah… no. That number is meaningless. Again, it hasn’t meant anything for over a decade at this point, so I can’t really knock on Acer too much for this.
That said, the monitor is probably good. I just can’t quantify how and why from the information we’re given. I do like the light-hood flaps on the side, though.

Tagged: vesa, displayid 2.0
This year has seen a lot of change in the technology used in monitors, with 4K, adaptive refresh rates above 120Hz and HDR becoming common features. These new features did not exist when DisplayID first replaced the veteran Extended Display Identification Data and so there were no overarching standards governing their implementation. We have also seen the advent of consumer VR and AR which also lacks a standard for companies to follow.
The new DisplayID 2.0 standard is specifically for these new devices, with the previous standards remaining to govern the compatibility of legacy products. The new standard describes how manufacturers can use the modular data block design to send clear information about their devices capabilities to the hardware powering the display. If followed this will greatly enhance the compatibility of variable refresh rate technology, screens with 4K or higher resolution and wearable displays.
This will help you avoid experiencing the frustrations early adopters have experienced and will hopefully restore displays to a state where they simply work when plugged into a compatible GPU. We won't see huge jumps in performance but this will certainly help in the development of 4K displays with high refresh rates, once the power of our GPUs catches up.

The AGON sacrifices 4k resolution to provide refresh rates of up to 144Hz; instead the 31.5" curved display offers a 1440p resolution, demonstrating its focus on gaming. The monitor also includes a QuickSwitch control, a physical keyboard which you can control the settings on your monitor, an extremely effective alternative to navigating an OSD with the buttons build into monitors. Kitguru tested the monitor out found it to be great for large screen gaming, but perhaps not for movie viewing as all the presets are gaming focused. The inputs were another point of contention, while comprehensive with two HDMI 2.0, two DisplayPort 1.2, VGA, headphone and mic jacks as well as two USB 3.0 ports, the placement is not the most convenient for some. Drop by for a look.
"Curved screens are really starting to come of age for gaming. We are seeing more and more of these, in many different sizes, and the latest to grace the KitGuru testing table is the AOC AGON AG322QCX. It’s pretty sizeable at 31.5in, but unlike many larger screens it’s still packed with features to please the serious gamer."

To start with the particular specification which will upset some people, the ASUS XG37VQ is a 1080p monitor; so if life starts at 1440p then feel free to move on. For those still reading, this Freesync monitor supports refresh rates from 48 to 144Hz and can display 95% sRGB coverage. Techgage were impressed with the quality of the display but when it came to the RGBs present on the monitor they had some questions; the ROG logo that is projected from the bottom of the monitor only comes in red, while the glowing circle on the back of the display supports a full gamut of colours which no one will ever see. Pop over for the full review.
"Let's cut right to the chase. The Asus ROG Strix XG27VQ is a $350 gaming monitor, 27 inches in size, with a resolution of 1920 x 1080 and a refresh rate of 144 Hz. We're looking at a VA LCD panel here with FreeSync support, sporting an 1800R curvature."

Philips recently revealed a massive 49” ultra-wide monitor slated for release in the second half of next year. The so-called Philips 492P8 takes the bigger is better approach with its 32:9 aspect ratio ultra-wide monitor based on the same VA (vertical alignment) panel as Samsung’s more expensive (and feature-full) CH90 QLED. With a planned MSRP of $1,077, Philips has cut a few features in its model namely support for AMD’s FreeSync 2 and Samsung’s QLED backlighting. It Is not yet clear whether or not the monitor will retain the same 144Hz refresh rate and high dynamic range (HDR).
The 49-inch diagonal monitor features a 3840 x 1080 resolution and a 1800R curvature. The 492P8 is rated at a maximum brightness of 600 cd/m2 and a contrast ratio of 5,000:1. The monitor is based on a VA panel which is a compromise between the fast response times and refresh rates of TN and the colors and viewing angles of IPS (and PLS) with strong contrast, good viewing angles, decent refresh rates (response times can be an issue in gaming as far as possible motion blur), and the ability to crank up the brightness. With the axing of FreeSync 2 support, this may not be the best option for gamers wanting an ultra-wide, but this monitor is sure to find a place in the corporate world with lots of side-by-side windows open in brightly lit office environments. Depending on reviews it could also be good for flight sims, 4X games, and other gaming as well.
The monitor features DisplayPort, HDMI, VGA, and USB Type-C display inputs (one each) as well as (using the USB Type-C port to connect to a PC) a two port USB 3.0 hub, one Ethernet jack, and two 3.5mm audio jacks (one headphone and one microphone).
The Philips 492P8 32:9 VA monitor is slated for a Q2 2018 release with a MSRP of $1,077 (C899). OF course, there is plenty of time for specifications and pricing to change between now and then, but it seems Philips is aiming for a budget option under $1100.
I would have liked to see more vertical resolution (I mean, why not at least 1200p? heh) but you can’t have everything, especially for cheap. What do you think about the 32:9 aspect ratio? Also, would you put a 49" ~34 pound monitor on your desk?
Acer Predator Z271T With Tobii Eye Tracking
It seems like it's never been a better time to be a PC gamer. With new technologies like VR, AR, HDR, adaptive sync, and high refresh rates being introduced or improved upon at a rapid pace, there's always something new and exciting right around the corner.
Today, we're taking a look at one new technology that promises to bridge the gap between traditional monitors and full-blown VR or AR setups: eye tracking. Originally developed for its use as an assistive device for users with disabilities, eye tracking is making a big jump to gaming, as it can both provide an additional method of control input as well as alter the way the user experiences the game.
We first took a look at Tobii a few years ago with an early standalone eye tracking device. Now Tobii eye tracking is starting to make its way directly into monitors, and we spent some time with one such monitor: the Acer Predator Z271T.
Specs & Box Contents
The Acer Predator Z271T -- which I'll refer to as "Z27" going forward -- is a $700 27-inch monitor with a curved VA panel, 1920x1080 native resolution, and 144Hz refresh rate. The complete technical specifications:

Tagged: Samsung, PLS
And, naturally, things break right when you make a big purchase. The day after I set up the Oculus, one of my monitors had a wobbly backlight and buzz, quickly going black-screen despite the on light showing it was connected. I revived it by turning it off and on again, but it was clear that it was dead. That said, I bought it back in ~2005-2006, so it lived a long life.
Its replacement? A 24-inch mainstream Samsung PLS, 1080p display. It was surprisingly difficult finding a cheap (but solid) monitor that also had a wall mount, but this one was luckily $80-off at Staples ($169.96 CDN before taxes until August 15th). It was also compatible with FreeSync, but my GPUs are NVIDIA so it’s not a feature that I can comment on. It doesn't have a high refresh rate or anything, but it seems very good (for its price) so far.
One thing that I will note, however, is that you need to be careful with your wall mounts... there’s a stub for the stand that will not come off, and there’s not much room between it and the VESA mounts. Unless you have holes at pretty much the very bottom of your mount, which I luckily did, you will need to buy a new mount (or do some hacky thing with standoffs or whatever).
