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.

New HDMI 2.1 Specification Supports Higher Resolutions, Refresh Rates, and Game Mode VRR

Subject: General Tech | January 6, 2017 - 04:22 AM |
Tagged: vrr, variable refresh rate, HDMI 2.1, hdmi, g-sync, freesync, adaptive sync, 48G

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). 

HDMI Cable.jpg

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?

AMD FreeSync 2 Brings Latency, LFC and Color Space Requirements

Subject: Graphics Cards, Displays | January 3, 2017 - 09:00 AM |
Tagged: srgb, lfc, hdr10, hdr, freesync 2, freesync, dolby vision, color space, amd

Since the initial FreeSync launch in March of 2015, AMD has quickly expanded the role and impact that the display technology has had on the market. Technologically, AMD added low frame rate compensation (LFC) to mimic the experience of G-Sync displays, effectively removing the bottom limit to the variable refresh rate. LFC is an optional feature that requires a large enough gap between the displays minimum and maximum refresh rates to be enabled, but the monitors that do integrate it work well. Last year AMD brought FreeSync to HDMI connections too by overlaying the standard as an extension. This helped to expand the quantity and lower the price of available FreeSync options. Most recently, AMD announced that borderless windowed mode was being added as well, another feature-match to what NVIDIA can do with G-Sync.

slides-3.jpg

The biggest feather in the cap for AMD FreeSync is the sheer quantity of displays that exist on the market that support it. As of our briefing in early December, AMD claimed 121 design wins for FreeSync to just 18 for NVIDIA G-Sync. I am not often in the camp of quantity over quality, but the numbers are impressive. The pervasiveness of FreeSync monitors means that at least some of them are going to be very high quality integrations and that prices are going to be lower compared to the green team’s selection.

slides-14.jpg

Today AMD is announcing FreeSync 2, a new, concurrently running program that adds some new qualifications to displays for latency, color space and LFC. This new program will be much more hands-on from AMD, requiring per-product validation and certification and this will likely come at a cost. (To be clear, AMD hasn’t confirmed if that is the case to me yet.)

Let’s start with the easy stuff first: latency and LFC. FreeSync 2 will require monitors to support LFC and thus to have no effective bottom limit to their variable refresh rate. AMD will also instill a maximum latency allowable for FS2, on the order of “a few milliseconds” from frame buffer flip to photon. This can be easily measured with some high-speed camera work by both AMD and external parties (like us).

These are fantastic additions to the FreeSync 2 standard and should drastically increase the quality of panels and product.

slides-17.jpg

The bigger change to FreeSync 2 is on the color space. FS2 will require a doubling of the perceivable brightness and doubling of the viewable color volume based on the sRGB standards. This means that any monitor that has the FreeSync 2 brand will have a significantly larger color space and ~400 nits brightness. Current HDR standards exceed these FreeSync 2 requirements, but there is nothing preventing monitor vendors from exceeding these levels; they simply set a baseline that users should expect going forward.

slides-16.jpg

In addition to just requiring the panel to support a wider color gamut, FS2 will also enable user experience improvements as well. First, each FS2 monitor must communicate its color space and brightness ranges to the AMD driver through a similar communication path used today for variable refresh rate information. By having access to this data, AMD can enable automatic mode switches from SDR to HDR/wide color gamut based on the application. Windows can remain in a basic SDR color space but games or video applications that support HDR modes can enter that mode without user intervention.

slides-15.jpg

Color space mapping can take time in low power consumption monitors, adding potential latency. For movies that might not be an issue, but for enthusiast gamers it definitely is. The solution is to do all the tone mapping BEFORE the image data is sent to the monitor itself. But with varying monitors, varying color space limits and varying integrations of HDR standards, and no operating system level integration for tone mapping, it’s a difficult task.

The solution is for games to map directly to the color space of the display. AMD will foster this through FreeSync 2 – a game that integrates support for FS2 will be able to get data from the AMD driver stack about the maximum color space of the attached display. The engine can then do its tone mapping to that color space directly, rather than some intermediate state, saving on latency and improving the gaming experience. AMD can then automatically switch the monitor to its largest color space, as well as its maximum brightness. This does require the game engine or game developer to directly integrate support for this feature though – it will not be a catch-all solution for AMD Radeon users.

This combination of latency, LFC and color space additions to FreeSync 2 make it an incredibly interesting standard. Pushing specific standards and requirements on hardware vendors is not something AMD has had the gall to do the past, and honestly the company has publicly been very against it. But to guarantee the experience for Radeon gamers, AMD and the Radeon Technologies Group appear to be willing to make some changes.

slides-18.jpg

NVIDIA has yet to make any noise about HDR or color space requirements for future monitors and while the FreeSync 2 standards shown here don’t quite guarantee HDR10/Dolby Vision quality displays, they do force vendors to pay more attention to what they are building and create higher quality products for the gaming market.

All GPUs that support FreeSync will support FreeSync 2 and both programs will co-exist. FS2 is currently going to be built on DisplayPort and could find its way into another standard extension (as Adaptive Sync was). Displays are set to be available in the first half of this year.

AOC Announces AGON AG251FZ 240Hz FreeSync Monitor

Subject: Displays | November 25, 2016 - 08:29 PM |
Tagged: AOC, 240Hz, freesync

This is just getting silly. While TN, 1080p monitors have been fading into the background, they are fast switching, and AOC is pushing that advantage. The AOC AGON AG251FZ is a 25-inch FreeSync display that can support up to 240 Hz refresh rates. They’re not the first monitor to reach this milestone, as Acer made a similar announcement back in August, but this display should be bright and smooth, especially for our readers with AMD GPUs.

AOC-2016-240hz-freesync.jpg

If you like to smoothly scroll documents, then you may also appreciate that its stand can pivot into portrait mode. I doubt it will have the best color representation, though, so those who want to photo edit, especially outside of sRGB, may want to look elsewhere. In fact, they don’t even list their sRGB (web and video) or AdobeRGB (video and print) coverage. I’d hope it would at least have 100% sRGB, but I can’t say for sure.

TechPowerUp claims that it will launch in January for about £449 GBP.

Microsoft updates Windows 10 UWP to support unlocked frame rates and G-Sync/FreeSync

Subject: Graphics Cards | May 10, 2016 - 12:11 PM |
Tagged: windows 10, windows, vrr, variable refresh rate, uwp, microsoft, g-sync, freesync

Back in March, Microsoft's Phil Spencer addressed some of the concerns over the Unified Windows Platform and PC gaming during his keynote address at the Build Conference. He noted that MS would "plan to open up VSync off, FreeSync, and G-Sync in May" and the company would "allow modding and overlays in UWP applications" sometime further into the future. Well it appears that Microsoft is on point with the May UWP update.

According to the MS DirectX Developer Blog, a Windows 10 update being pushed out today will enable UWP to support unlocked frame rates and variable refresh rate monitors in both G-Sync and FreeSync varieties. 

windows_8_logo-redux2.png

As a direct response to your feedback, we’re excited to announce the release today of new updates to Windows 10 that make gaming even better for game developers and gamers.

Later today, Windows 10 will be updated with two key new features:

Support for AMD’s FreesyncTM and NVIDIA’s G-SYNC™ in Universal Windows Platform games and apps

Unlocked frame rate for Universal Windows Platform (UWP) games and apps

Once applications take advantage of these new features, you will be able to play your UWP games with unlocked frame rates. We expect Gears of War: UE and Forza Motorsport 6: Apex to lead the way by adding this support in the very near future.

This OS update will be gradually rolled out to all machines, but you can download it directly here.

These updates to UWP join the already great support for unlocked frame rate and AMD and NVIDIA’s technologies in Windows 10 for classic Windows (Win32) apps.

Please keep the feedback coming!

Today's update won't automatically enable these features in UWP games like Gears of War or Quantum Break, they will still need to be updated individually by the developer. MS states that Gears of War and Forza will be the first to see these changes, but there is no mention of Quantum Break here, which is a game that could DEFINITELY benefit from the love of variable refresh rate monitors. 

Microsoft describes an unlocked frame rate as thus:

Vsync refers to the ability of an application to synchronize game rendering frames with the refresh rate of the monitor. When you use a game menu to “Disable vsync”, you instruct applications to render frames out of sync with the monitor refresh. Being able to render out of sync with the monitor refresh allows the game to render as fast as the graphics card is capable (unlocked frame rate), but this also means that “tearing” will occur. Tearing occurs when part of two different frames are on the screen at the same time.

I should note that these changes do not indicate that Microsoft is going to allow UWP games to go into an exclusive full screen mode - it still believes the disadvantages of that configuration outweigh the advantages. MS wants its overlays and a user's ability to easily Alt-Tab around Windows 10 to remain. Even though MS mentions screen tearing, I don't think that non-exclusive full screen applications will exhibit tearing.

gears.jpg

Gears of War on Windows 10 is a game that could definitely use an uncapped render rate and VRR support.

Instead, what is likely occurring, as we saw with the second iteration of the Ashes of the Singularity benchmark, is that the game will have an uncapped render rate internally but that frames rendered OVER 60 FPS (or the refresh rate of the display) will not be shown. This will improve perceived latency as the game will be able to present the most up to date frame (with the most update to date input data) when the monitor is ready for a new refresh. 

UPDATE 5/10/16 @ 4:31pm: Microsoft just got back to me and said that my above statement wasn't correct. Screen tearing will be able to occur in UWP games on Windows 10 after they integrate support for today's patch. Interesting!!

For G-Sync and FreeSync users, the ability to draw to the screen at any range of render rates will offer an even further advantage of uncapped frame rates, no tearing but also, no "dropped" frames caused by running at off-ratios of a standard monitor's refresh rate.

I'm glad to see Microsoft taking these steps at a brisk pace after the feedback from the PC community early in the year. As for UWP's continued evolution, the blog post does tease that we should "expect to see some exciting developments on multiple GPUs in DirectX 12 in the near future."

AMD adds panel types and frequency ranges to their FreeSync page

Subject: Displays | May 2, 2016 - 05:53 PM |
Tagged: freesync, amd, about damn time

Better late than never, our friend Robert Hallock has informed the world that AMD has updated their FreeSync display list with response ranges and panel types.  Having the physical size of the display, the resolution and the accepted inputs are necessary but this update offers a much better look at the displays you will be getting.  If you are unwilling to give up the colour reproduction of a IPS panel for the speed of an TN this is invaluable to you, as is pointing out the few VA based monitors.

FreeSync_technology.png

Listing the top and bottom frequencies of the variable refresh displays is arguably even more important.  We now know that currently only the Acer XR341CK and BX340CK, the Nixeus NX-VUE24 and the Viewsonic XG2701 are capable of dropping to 30Hz and that a total of 17 models can reach 144Hz.  Check out the list for the available 4K displays as well as regular 1440p and ultra-wide 1440p displays in the list and refer back to it regularly as there are a few monitors awaiting final specifications and more coming out in the near future.

Samsung Curved 1080p Monitors First with AMD FreeSync over HDMI

Subject: Displays | March 2, 2016 - 05:17 PM |
Tagged: amd, freesync, hdmi, Samsung

Earlier this week Samsung formally made a couple of announcements for new monitors due out this spring. The CF591 and CF390 range in size from 23 to 27 inches, mating a 1920x1080 resolution with an 1800R curvature and an attractive design. Even better news for gamers, all of the monitors in these two series will offer AMD's variable refresh rate technology known as FreeSync over HDMI.

cf1.jpg

The specifications of the monitors are interesting in their own light. The CF390 will be available in both 23.5-in and 27-in varieties, with a 1920x1080 resolution on a VA panel, a 4ms response time rating and a maximum brightness of 250 nits. The VA technology allows for solid viewing angles and color reproduction though all of them are limited to a 60Hz maximum refresh rate. The CF591 monitor is only available in a 27-in variety, shares almost all of the same traits, but sheds the glossy black design for a silver and white color option. 

cf2.jpg

Samsung CF390

The CF390 features only VGA (D-Sub) and HDMI inputs while the CF591 overs VGA, dual HDMI and a single DisplayPort connection as well. Only the CF591 allows for audio input through a 3.5mm connection.

cf3.jpg

Samsung CF591

The supposed value of HDMI-based FreeSync is ubiquity and lower cost. Unfortunately, we don't have any pricing information from Samsung on either the CF390 or CF591 monitors, leaving a big question mark for AMD Radeon gamers that might be looking for a new display. Also, while the CF390 directly benefits from the addition of HDMI support on FreeSync, the CF591 still has a DisplayPort connection, meaning the value of HDMI-based FreeSync is lessened.

cf4.jpg

They 60Hz maximum refresh rate is disappointing in a world where 75Hz, 90Hz, even 165Hz monitors are being released left and right. Will the AMD driver-based frame doubling technology work on these displays? I have an inquiry in to AMD to verify but it might be difficult with the VA panels' minimum refresh rate. To be fair to AMD and Samsung though, this isn't marketed as a gaming monitor, just a monitor that happens to have a very gaming friendly option.

Both of these monitors look pretty sexy though; we need to see and test them in person to see if the image quality and FreeSync performance meet our expectations. Hopefully we'll be able to do so soon, but until then, let's hope that Samsung is able to release these at very competitive prices to help drive down the cost of VRR.
