AMD's under reported dynamic refresh rates

The Tech Report learned yesterday of a feature that AMD has been offering over the past three generations of GPU called dynamic refresh rate, which they billed as a power saving feature.  Skipping an unnecessary vertical screen refresh would certainly save you a bit of power but really isn't that attractive a feature.  NVIDIA looked at this feature in the opposite way, not to save power but to refresh your screen as quickly as it is capable of to provide much smoother graphics and that marketing has had G-SYNC on everyone's lips.  Assuming AMD can get the word out, their variable refresh rate technology should be compatible with most new mobile/laptop products based on the EDP specification, no additional costs or equipment required.

"During an impromptu meeting in a hotel ballroom this morning, we got an eye-opening demo of a dynamic refresh rate capability that's been a part of Radeon GPUs for several generations. AMD thinks this feature can be combined with triple buffering to deliver G-Sync-like animation smoothness without the cost associated with specialized display hardware."

CES 2014: ASUS ROG SWIFT PG278Q (120+ Hz, G-Sync)

Subject: General Tech, Displays, Shows and Expos | January 6, 2014 - 12:18 PM |
Tagged: g-sync, CES 2014, CES, asus

Another G-Sync panel has been announced at CES. This one is not a standard 1080p panel, which is promising, rather a bump in resolution to WQHD 2560x1440 while still reaching "120+ Hz". It is still based on TN pixels but the resolution is different so at least that is progress. Perhaps we will see some IPS (or similar) displays later? Hopefully? I'm serious, I do not have inside information.

The SWIFT PG278Q is 27-inch with a narrow (6mm) bezel. The stand allows for tilt, swivel, height, and pivot adjustments which could be useful if you want to present portrait images or handle long documents. That said, I was really looking forward to pivot when I purchased my most recent monitor (last year) and eventually found that it was more convenient to use two documents side-by-side with Aero snap.

One feature that ASUS added to the panel was "GamePlus" which would probably not be the best to use in a LAN party. It enables custom crosshairs and timers on screen. I am sure that someone will interpret that as cheating (especially for games which disable crosshairs such as Battlefield 4 "hardcore"). They claim it is a practice tool, which I will accept, just use it in public at your own risk.

The monitor will be available in Q2 for $799 USD.

Press release after the break!

CES 2014: Philips 27" 144Hz Monitor with G-Sync

Subject: General Tech, Displays, Shows and Expos | January 5, 2014 - 08:50 PM |
Tagged: philips, g-sync, CES 2014, CES

One of the big questions we had leading into CES was exactly how many G-Sync panels we would see. If several monitor developers sign on then we would assume that it has a bright future. If we can count the number of models on one hand (and all of them 1080p TN-based panels) then we would have serious doubts.

Philips-Nvidia-G-Sync.jpg

Philips has just contributed a monitor to the mix: the 272G5DYEB; however, it is a 27-inch 1080p panel based on TN technology. It is capable of 144 Hz refresh rate and will be available in Spring. Its only input is DisplayPort as is common with G-Sync. There is not too much different about this panel compared to the ASUS version which has recently been made available. Hopefully this will be one of many announcements.

The Philips 27" Gaming Monitor with G-SYNC (272G5DYEB) will be available in Spring 2014 for $649 USD.

Introduction and Unboxing

Introduction:

We've been covering NVIDIA's new G-Sync tech for quite some time now, and displays so equipped are finally shipping. With all of the excitement going on, I became increasingly interested in the technology, especially since I'm one of those guys who is extremely sensitive to input lag and the inevitable image tearing that results from vsync-off gaming. Increased discussion on our weekly podcast, coupled with the inherent difficulty of demonstrating the effects without seeing G-Sync in action in-person, led me to pick up my own ASUS VG248QE panel for the purpose of this evaluation and review. We've generated plenty of other content revolving around the G-Sync tech itself, so lets get straight into what we're after today - evaluating the out of box installation process of the G-Sync installation kit.

Reader Results: NVIDIA G-Sync Upgrade and First Impressions

Subject: Displays | January 3, 2014 - 08:10 AM |
Tagged: reader results, nvidia, gsync, g-sync

Editor's Note: Late last December NVIDIA gave us the opportunity to hand out 5 of the NVIDIA G-Sync upgrade kits for the ASUS VG248QE display to PC Perspective readers.  Part of the deal though was that those winners agree to give us feedback on the upgrade experience and the real-world experience of using NVIDIA G-Sync on their gaming rig.  Below is the (slightly edited) results sent in by one Levi Kendall.  We'll likely post other users' results as well when the start to filter in.  

So, if you are curious what it will be like to upgrade and use your own G-Sync monitor, I think the experiences described by Levi below are going to be very interesting.

Also, don't forget to read over my overview of NVIDIA's G-Sync technology and my initial impressions in this article as well!

 

Installation thoughts:

This was a fairly serious product mod, actually more than I thought it was going to be.  Overall, the installation took more than an hour, so not exactly trivial for me.  I suppose it's possible to get it done in 30 minutes if you were really focused and knew what you were doing. I put the LVDS connector on wrong the first time (connectors had to be rotated 180 degrees) so I had to retrace my steps for a bit to get it fixed after I realized it was put on incorrectly and the metal plate was on the wrong side.  The manual does actually point this out in a couple steps but it was a little confusing to think of that rotation change.  Also, during installation I opted to remove the somewhat useless monitor speakers (that nobody probably uses anyway).  It's definitely something a PC hobbyist can do, but count on spending some time carefully removing a lot of small cables inside the monitor and doing it right.  Part of my slow approach was caution at damaging any components; I've never been inside an LCD display until now.

Installation Step 1

First impressions:

The OSD settings through the monitor buttons are greatly reduced (fortunately simplified) after the mod.  It's not really an issue since it looks amazing, but the display controls seem to be basically just a brightness option +/- now.  I'm happy with the gamma particularly in dark levels as I don't feel like I have to fool with it now and the ASUS OSD was a bit clunky to work with anyway.  The various display "modes" of the VG248QE weren't something I really used much before, just got it to the point it looked nice to me and left it alone.  The monitor also powers up nearly instantly as opposed to the delay of showing the animated ASUS logo which is nice.

Installation Step 2

For more detailed display setting tweaks I downloaded a free utility called “softMCCS” and this has allowed me to access things like the detailed color settings and contrast.  This software seems a little buggy but overall it does work at least.  Unfortunately NVIDIA did not provide any official MCCS software utility in the package.

Game play testing:

In games where the frame rate was already consistently 144+ it's hard to say precisely where the difference is.  The VG248QE was already a beastly fast gaming monitor to start from.  It feels to me like the latency might have gone down a little bit with G-Sync, everything does feel a bit more responsive and caught up very close with player inputs.  Where G-Sync becomes more noticeable to me is in games where the frame rate is dropping somewhere below the magical 144 mark and you see this kind of graceful degradation in performance and game play remains very fluid even when the action ramps up and you are in a lower FPS situation.

NVIDIA G-Sync Monitors Limited Availability Starting Today

Subject: Displays | December 16, 2013 - 06:11 AM |
Tagged: video, vg248qe, nvidia, gsync, g-sync, asus

It looks like some G-Sync ready monitors are going to be on sale starting today, though perhaps not from the outlets you would have expected.  NVIDIA let me know last night that they are working with partners, including ASUS obviously, to make a small amount of pre-modified ASUS VG248QE G-Sync monitors available for purchase. These are the same monitors we used in our recent G-Sync preview story so you should check that article out if you want our opinions on the display and the technology. 

Those people selling the displays?  Digital Storm, Falcon Northwest, Maingear, and Overlord Computer.  This creates some unfortunate requirements on potential buyers.  For example, Falcon Northwest is only selling the panels to users that either are buying a new Falcon PC or already own a Falcon custom system.  Digital Storm on the other hand WILL sell the monitor on its own or allow you to send in your VG248QE monitor to have the upgrade service done for you.  The monitor alone will sell for $499 while the upgrade price (with module included) is $299. 

gsync1.JPG

This distribution model for G-Sync technology likely isn't what users wanted or expected.  After all, we were promised upgrade kits for users of that specific ASUS VG248QE display and we still do not have data on how NVIDIA plans to sell them or distribute them.  Being able to purchase the display from these resellers above is at least SOMETHING before the holiday, but it really isn't the way we would like to see G-Sync showcased.  NVIDIA needs to get these products in the hands of gamers sooner rather than later.

NVIDIA also prepared a new video to showcase G-Sync.  Unlike other marketing videos this one wasn't placed on YouTube as the ability for it to run at a fixed 60 FPS is a strict requirement, something that YouTube can't do or can't do reliably.  For this video's demonstration to work correctly you need set your display to a 60 Hz refresh rate and you should use a video player capable of maintaining the static 60 FPS content decoding.

To grab a copy of this video, you can use the link right here that will download the file directly from Mega.co.nz.  It should help demonstrate the effects us using a G-Sync enabled display for users that don't have access to see one in person.

Oh, and I know that LOTS of you have been clamoring for information on how you can get your hands on one of those DIY G-Sync upgrade kits for yourself and I have some good news.  Though I can't tell you where to buy one or how much it will cost, I can offer you one of 5 FREE G-Sync ASUS VG248QE upgrade kits through a giveaway we are hosting at PC Perspective!  Check out this page for the details!!

Quality time with G-Sync

Readers of PC Perspective will already know quite alot about NVIDIA's G-Sync technology.  When it was first unveiled in October we were at the event and were able to listen to NVIDIA executives, product designers and engineers discuss and elaborate on what it is, how it works and why it benefits gamers.  This revolutionary new take on how displays and graphics cards talk to each other enables a new class of variable refresh rate monitors that will offer up the smoothness advantages of having V-Sync off, while offering the tear-free images normally reserved for gamers enabling V-Sync.

NVIDIA's Prototype G-Sync Monitor

We were lucky enough to be at NVIDIA's Montreal tech day while John Carmack, Tim Sweeney and Johan Andersson were on stage discussing NVIDIA G-Sync among other topics.  All three developers were incredibly excited about G-Sync and what it meant for gaming going forward.

Also on that day, I published a somewhat detailed editorial that dug into the background of V-sync technology, why the 60 Hz refresh rate existed and why the system in place today is flawed.  This basically led up to an explanation of how G-Sync works, including integration via extending Vblank signals and detailed how NVIDIA was enabling the graphics card to retake control over the entire display pipeline.

In reality, if you want the best explanation of G-Sync, how it works and why it is a stand-out technology for PC gaming, you should take the time to watch and listen to our interview with NVIDIA's Tom Petersen, one of the primary inventors of G-Sync.  In this video we go through quite a bit of technical explanation of how displays work today, and how the G-Sync technology changes gaming for the better.  It is a 1+ hour long video, but I selfishly believe that it is the most concise and well put together collection of information about G-Sync for our readers.

The story today is more about extensive hands-on testing with the G-Sync prototype monitors.  The displays that we received this week were modified versions of the 144Hz ASUS VG248QE gaming panels, the same ones that will in theory be upgradeable by end users as well sometime in the future.  These monitors are TN panels, 1920x1080 and though they have incredibly high refresh rates, aren't usually regarded as the highest image quality displays on the market.  However, the story about what you get with G-Sync is really more about stutter (or lack thereof), tearing (or lack thereof), and a better overall gaming experience for the user.
