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.

The response to Al's review of the ASUS MG279Q was, to be polite, somewhat energetic. While not much was learned a lot of opinions were voiced and occasionally they were even on topic. The Tech Report, not dissuaded by the response just posted a 10 minute video offering their thoughts on the new Freesync technology in general and this monitor specifically. The Closed Caption feature offers some rather amusing translations of what is being said but you should pay attention to what is actually being said as the video offers a good overview of what FreeSync is.
"Asus' MG279Q is a 27" FreeSync monitor with a 144Hz, 2560x1440 IPS panel for an appealing price. Our own Gyromancer, Nathan Wasson, has spent some quality time with the MG279Q, and he's collected his impressions in video form."

availability of the beta version of their GameWorks VR. As mentioned on this podcast, until now your GPU has treated the Oculus as a secondary monitor but with this update your graphics driver will directly talk to the Oculus as a separate device, which should help greatly with latency and development of the tricks and treats yet to be discovered when programming for this type of interface.

NVIDIA's Gameworks VR, as well as AMD's LiquidVR will provide a platform for developers to program for the Oculus Rift as well as the competeing products from other companies. The new beta SDK from NVIDIA has been updated to support VR SLI and is compatible with the new 350.60 Game Ready drivers. Programmers working with the Maxwell architecture will benefit from Multi-Res Shading which should increase the performance of your current programs. Follow the links if you are interested in developing for Oculus, otherwise wait patiently for the day you can pre-order them.
A few years ago, we took our first look at the inexpensive 27" 1440p monitors which were starting to flood the market via eBay sellers located in Korea. These monitors proved to be immensely popular and largely credited for moving a large number of gamers past 1080p.
However, in the past few months we have seen a new trend from some of these same Korean monitor manufacturers. Just like the Seiki Pro SM40UNP 40" 4K display that we took a look at a few weeks ago, the new trend is large 4K monitors.
Built around a 42-in LG AH-IPS panel, the Wasabi Mango UHD420 is an impressive display. Inclusion of HDMI 2.0 and DisplayPort 1.2 allow you to achieve 4K at a full 60Hz and 4:4:4 color gamut. At a cost of just under $800 on Amazon, this is an incredibly appealing value.
Whether or not the UHD420 is a TV or a monitor is actually quite the tossup. The lack of a tuner
might initially lead you to believe it's not a TV. Inclusion of a DisplayPort connector, and USB 3.0 hub might make you believe it's a monitor, but it's bundled with a remote control (entirely in Korean). In reality, this display could really be used for either use case (unless you use OTA tuning), and really starts to blur the lines between a "dumb" TV and a monitor. You'll also find VESA 400x400mm mounting holes on this display for easy wall mounting.
We have been tracking the differences between AMD’s FreeSync and Nvidia’s G-Sync for some time now. The launch of FreeSync-capable displays started out a bit shaky, as some features we took for granted went missing. The first round of FreeSync displays we reviewed came with non-functional overdrive when the display / GPU pipeline was operating in FreeSync mode.
Comparison of overdrive response in first round FreeSync displays. Images should look like the ROG Swift (left), which was correctly applying overdrive.
While AMD apparently fixed a portion of this problem in a subsequent driver update, getting overdrive to function in these early displays would require a firmware update. Unlike what you may be used to with a motherboard or SSD firmware, displays are not typically end-user upgradeable. This meant that even if manufacturers produced a fix, owners would have to send in their display to be updated (and be without it for several weeks).
The only manufacturer to step forward and retroactively support overdrive in their first gen FreeSync panel was BenQ. In a statement issued via TFTCentral:
BenQ have confirmed that the FreeSync/AMA issue which affected their XL2730Z display has now been fixed. This issue caused the overdrive (AMA) feature to not function when the screen was connected to a FreeSync capable system. As a result, users could not make use of the AMA feature and benefit from the improved response times that the 'normal' AMA mode offered, as compared with AMA Off. See our review for more information.
A driver update from AMD is already available and should be downloaded from their website. In addition BenQ will be releasing a firmware update for the monitor itself to fix this issue. Current stocks in distribution are being recalled and updated with retailers so future purchases should already carry this new firmware. This is expected to apply for stock purchased AFTER 1st July, as V002 firmware screens should be shipped by BenQ to distributors in late June.
For those who already have an XL2730Z if you want to, you can return it to BenQ for them to carry out the firmware update for you. This only applies if the user is experiencing issues with the performance of the screen. There is no simple way for the end user to update the firmware themselves and it is not encouraged. Users should contact BenQ support through their relevant country website for more information on how to return their screen for the update.
The catch with the above is that the statement came from BenQ PR for Europe, and we nor TFTCentral have been able to confirm any equivalent upgrade process in place for the USA. We did note in various online reviews that those receiving their BenQ XL2730Z in the last week of June confirmed having the new V002 firmware.
If you have one of these panels, verifying your firmware is simple. Hold down the menu button while powering up the display (you will have to hold the power button for a few seconds before you hear a beep).
The display will power up and appear as normal, except that now pressing the menu button again will bring up the above service menu. Those with the update will have “V002” as the starting text of the ‘F/W Version’ result.

We have been eager to retest the BenQ since hearing of this updated firmware revision. While we have seen overdrive functioning in the recent ASUS MG279Q, it was not a perfect implementation, and we were curious to know if BenQ’s implementation fared any better.
If you live somewhere you can visit or order from a Microcenter and consider a great value enough reason to use a TN based display then check out this deal on an AOC U2870VQE 28" 4K LED display. Currently only $349+taxes you can get a 4k display for your computer or to stream to from your mobile device. Again, at this price you cannot expect either adaptive refresh rate technology but for roughly the same price to pick up an IPS based FreeSync or G_SYNC monitor of comparable size you can grab three of these displays. Connectivity includes VGA, DP, Mini-DP and HDMI (MHL), the latter of which is compatible with mobile devices.
The display is sold as a 10-bit panel, in fact it is an 8bit panel which uses Frame-Rate-Control to up the number of colours to 1.07 billion but frankly unless you are using this for professional purposes you are not going to notice any difference; except the price of course. You can see the full news release below the fold, or just click on that link to order one for as you might expect, the supplies at this price are limited. Otherwise you can keep saving your pennies for a 4k IPS display with true 10bit colour and one of the two adaptive refresh rate technologies.
Introduction, Specifications, and Packaging
AMD fans have been patiently waiting for a proper FreeSync display to be released. The first round of displays using the Adaptive Sync variable refresh rate technology arrived with an ineffective or otherwise disabled overdrive feature, resulting in less than optimal pixel response times and overall visual quality, especially when operating in variable refresh rate modes. Meanwhile G-Sync users had overdrive functionality properly functioning , as well as a recently introduced 1440P IPS panel from Acer. The FreeSync camp was overdue for an IPS 1440P display superior to that first round of releases, hopefully with those overdrive issues corrected. Well it appears that ASUS, the makers of the ROG Swift, have just rectified that situation with a panel we can finally recommend to AMD users:
Before we get into the full review, here is a sampling of our recent display reviews from both sides of the camp:
- ASUS PG278Q 27in TN 1440P 144Hz G-Sync
- Acer XB270H 27in TN 1080P 144Hz G-Sync
- Acer XB280HK 28in TN 4K 60Hz G-Sync
- Acer XB270HU 27in IPS 1440P 144Hz G-Sync
- LG 34UM67 34in IPS 25x18 21:9 48-75Hz FreeSync
- BenQ XL2730Z 27in TN 1440P 40-144Hz FreeSync
- Acer XG270HU 27in TN 1440P 40-144Hz FreeSync
- ASUS MG279Q 27in IPS 1440P 144Hz FreeSync(35-90Hz) < You are here
The reason for there being no minimum rating on the G-Sync panels above is explained in our article 'Dissecting G-Sync and FreeSync - How the Technologies Differ', though the short version is that G-Sync can effectively remain in VRR down to <1 FPS regardless of the hardware minimum of the display panel itself.

Earlier today we posted our review of the Seiki Pro SM40UNP monitor, a 40-in behemoth with a 4K resolution and 60 Hz refresh rate. Clearly this is not a monitor for mere mortals: you must have an impressive system to push out the pixels required for a 4K display and also have the desk space for a display that many would considerable sizeable for a TV!
Not only was Allyn impressed with the color capability of the display and the sheer size of the monitor, it offers some interesting features and capabilities including four simultaneous video inputs! Be sure you check out Allyn's full write up on the display that resulted in a Gold Award from the staff.
But let's get to the important news for this post: Seiki was willing to give us two of these monitors to hand out to our readers and viewers. That's right, two of you will be taking home a 40-in 4K 60 Hz monitor for your gaming PC! (Or for productivity and work, who are we to judge?)
The method is simple:
- Fill out the entry form below. You can enter through one or all of the methods listed but the more entries you include the better your chances! Seiki is particular interested to see all the 4K-ready gaming rigs our readers have built!
- It's stated in the Gleam form but it is worth reiterating here: all entrants will be sent one email from me (Ryan) with a coupon code for Seiki monitors that you can use on a purchase if you don't win one of the giveaways. You are not being signed up for some kind of mailing list or marketing list and your email address will never actually go to Seiki - I will send out the emails myself.
- The contest is open to anyone in the world. So enter away!
- The contest will end at 11:59pm on June 19th (EST)
Good luck to all entrants and a HUGE THANKS goes out to Seiki for providing these kick-ass prizes for our readers and viewers!

Introduction and Specifications
Seiki has spent the past few years making quite the entrance into the display market. Starting with LCD TVs, they seemingly came out of nowhere back in April of 2013 with a 50” 4K display that was available at a very competitive price at that time. Since then, we’ve seen a few more display releases out of Seiki, and they were becoming popular among home theater enthusiasts on a budget and for gamers who wanted a bigger panel in front of them. Last June, Seiki announced a desktop line of 4K monitors. These would not just be repurposed televisions, but ground-up designs intended for desktop professionals and gamers alike. The most eagerly awaited part of this announcement was promised 60 Hz support at 4K resolutions.
Just under a year later, we are happy to bring you a review of the first iteration on this new Seiki Pro lineup:
