Independent G-SYNC Compatibility Testing Begins at Rtings

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."

From RTings:

"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.

jen son, master of hyperbole and bullshit, made it seem that if a freesync monitor had issues with nvidia implementaiton of adaptive sync, then it would have issues with amd cards as well. it seems from what i hear around the net and this video that what he suggested is absolute bullshit. The truth is most freesync monitors, except really shitty, cheap ones, work fine with amd gpu's notwithstanding their not working with nvid gup's.

Please rethink 'picks of the week.' They have always seemed to be an afterthought at best and a paid for product plug at worst.

maybe you can do a "deal alert" whereby at the time of the show there is a great deal on a relevant piece of hardware

"a paid for product plug"

Any paid advertisement is labeled as such, per FTC guidelines. I welcome all constructive criticism, polite or not, but I draw the line at accusations of unethical behavior. That will not happen, period, or someone is getting fired. I never did that crap as an editor, and have zero tolerance from anyone here as editor-in-chief.

Back to the point: You don't like picks of the week? If enough people share your opinion they will disappear.

give me credit for still listening

sorry you took it that way but it was supposed to be constructive and i am still here after many years and want you guys to succeed

i did say 'at worst'

i am thinking an awesome 'deal alert' type of thing and not eliminating it all together

btw, aptX LL is a good thing, but the compression does not lend itself to high fidelity listening

i for one am super excited about the new evga sound card

thanks evga for looking out for those of us who love to listen to music with little to no compromise in the sound quality

no sebastian, you are not the only one of us who like flat sound at a great price

January 21, 2019 | 08:30 PM - Posted by Sebastian Peak

Wired always wins for sound quality of course. aptX is only my preference when I have to use Bluetooth. I'll have that sound card review done pretty soon, have to get part two of the RTX 2060 done first.

As to the previous comments, I feel pretty strongly about integrity. That's all. Feel free to question anything we're doing here and if it seems suspect we haven't been transparent enough.

January 21, 2019 | 09:30 PM - Posted by pdjblum

no doubt about your integrity and glad you are running the show, as i suggested you should over a year ago if you look at the comments

IT's a good thing you commented back then, he couldn't have done it without you.

Canadian here, so picks of the week aren't usually such good deals. However, they're of interest if the team have personal experience of the product and can explain their recommendation from that POV.

Also, it would be nice if PCper could run a similar test of freesync monitors with nvidia GPU's that aren't on the nvidia list.

January 21, 2019 | 08:30 PM - Posted by pdjblum

the problem i see with that and with sites that have done testing is that the sites don't test the monitor with an amd gpu as well

that way, it will show that most of the issues are with nvidia implementation and not the monitor

January 21, 2019 | 08:32 PM - Posted by Sebastian Peak

That was the highlight of the Rtings testing to me - every monitor was tested using both a GTX 1060 and an RX 580, and the results compared. Turns out most of the time the results were the same - but they mentioned some exceptions as well. I would love the time and equipment to test as thoroughly as that site does - they are a great resource for display reviews. Something to work toward.

The expectation has always been that AMD GPU's would work with Freesync monitors, so that part of is not news. Only someone looking for ammo in the GPU wars would claim otherwise.

However, if someone is looking to buy a new VRR monitor, they will want to know how well it works with nvidia GPU's. Hopefully you folks can include such testing in any future monitor reviews.

First of all FreeSync(TM) is a regestered trademark by AMD so why do the words Nvidia and FreeSync come into play when the VESA Display Port Adaptive-Sync 1.2a standard is what Nvidia supports.

What's with the Trademark abuse going on with the Technology Press and?

Nvidia does not have a FreeSync implementation Nvidia has a VESA Display Port Adaptive-Sync implementation. What about fixing your Trademark Violation and you and the rest of the tecnology press have no rights to even assoicate Nvidia with that AMD Trademarked Brand as the only legal branding that Nvidia/Technology Press can utilize is VESA's Display Port Adaptive-Sync 1.2a Branding.

AMD also owns the FreeSync 2 branding but the VESA Display Port Adaptive-Sync 1.2a Standard does not cover FreeSync 2 in the adopted VESA standards currently.

Because the monitors are advertised as supporting Freesync?

Of all the hills you could choose to die on, you chose this one?

HardwareUnboxed did a video testing 7 freesync monitors both on nvidia gpus and amd gpus and came to the same conclusion, they work well on either vendor of GPU's.

Jensen is great at stretching the truth to the point it is pretty much a lie, we can all agree on that one.

Also, picks of the week at best has been about finding good deals to pass them on, but often it's more about humor and entertainment when some good deal can't be found. I enjoy that format the way it is and I'm pretty sure most do too.

forgot to add, the monitors tested by HU are all not on that approved "compatibility" list of 12.

January 23, 2019 | 05:55 AM - Posted by AnonymousNubbins (not verified)

Anyone remember Allyn's "nubbins" or something pick-of-the-week? Really useful, really cool, so completely off topic I laughed the whole time yet I wish I had some :)

What all of these tests and almost all commenters misunderstood is that they never said they don’t work they only said that the compatible monitors live up to the gsync standard requirements. This means color calibration, refresh rate, motion blur and a lot of other parameters. Now most freesync monitors failed that high bar but many do ‘work’ just as well as they do when driven by amd cards but the point is that most deliver a sub par experience. Which most rewievers and commenters seem to be unaware of.

Rtings review regarding to this subject is quite good, it even had obscure monitor but quite popular in asia that not many 'western' site review it (LG 24MP59G, which is also the monitor I bought). And after tried it myself what they said in their review is absolutely true

The best monitor just became available for preorder. Puts most gsync monitors to shame.
