TESTS AND FACTUAL ANALISYS

"subjective analisys" (the title of the page itself
The panel's 75Hz rate and decent response time meant there was no visible ghosting either. If you're viewing content with a 16:9 or 16:10 aspect ratio, however, you'll end up with large, unused portions of the screen, like you see in the 4K Avengers clip above.
We also did quite a bit of gaming on the LG 34UM67, both with and without FreeSync enabled. We played some older titles like Left 4 Dead 2 (which can run at very high frame rates), and some newer titles like Crysis 3 and Metro Last Light.
When playing games that run at very high frame rates, the effects of FreeSync aren't quite as noticeable. We're sure if you stopped and stared and looked specifically for visual artifacts, you'd find some, but during actual gameplay they are not always noticeable.
When playing more taxing games, however, with frame rates that may fluctuate above or below 60 FPS or so, the effect FreeSync has on the on-screen imagery and / or lag is great. Disabling V-Sync may eliminate lag, but tearing is evident. And enabling V-Sync may eliminate the tearing, but the lag can be annoying. With FreeSync, the on-screen images don't suffer from visual artifacts and the tearing is also gone.
We wish there was an easy way to visually convey how adaptive fresh technologies like FreeSync and G-Sync affects on-screen animation, but there isnt. We dont have a means to capture DisplayPort feeds and shooting video of the screen and hosting it on-line doesnt capture the full effect either. In lieu of an easy visual method to show how effective adaptive refresh rates can be, you'll just have to take our word for it.
We should also mention that simply using a higher refresh rate on your desktop is also great. There is a noticeable improvement when mousing or even moving windows around the screen, even at the LG 34UM67's 75Hz. If you're the type that gets headaches when looking at a 60Hz screen for too long, higher refresh rates may also help with that.
one review has stats and charts. the other has "feels". feel free to go with the second if you dont care about the actual science behind these two technologies.
a "good" review would be putting a freesync monitor next to a crt and film it on high speed camera. measure the input lag of a mouse factually and not limit yourself to "it feels fine". because in many applications i would not be able to "feel" the lag which is, nevertheless, affecting me. just because its not "visible" it doesnt mean its not there.
I hope the other monitors will be significantly better than the LG. 48 minimum FPS to keep freesync running is rather high. Also looking forward to highspeed cam compares between freesync and gsync.
Which leads into my next question: wouldn't playing back full screen film or video content result in the display synchronizing to the movie frame rate? Seems like something MPC, XBMC, VLC, etc. should work on to force FreeSync/G-Sync displays to match content frame rate (24/30/48/60/etc.) or offer multiples of it. NO MOAR pulldown and frame rate conversions!
ok i'll grant you that and i take back the "BS" comment.It's not particularly in-depth and by their own labeling subjective but that doesn't make it "BS". Maybe they don't have the required equipment. I agree some more data would be better but subjective analysis has it's place.
I am not sure, but I think AMD said in order to get FreeSync working with video playback you need the windows media player or something like that. In other words it's not something that can work on every player.
Not 100% sure on that though.
As for FreeSync, so far I loved it. If you've ever used G-Sync, it's going to feel identical to you - but for Radeon GPUs. If you haven't used G-Sync, and you're a gamer, then I urge you to try it. Once you've used FreeSync, you're not going to go back. It's just so incredibly hard. It would be like using a ball mouse to one of the new mice on the market from a company like Corsair, and then going back to the ball mouse - it's a resounding no.
Wrapping things up, I'm quite excited about spending more time with FreeSync and the LG 34UM67. FreeSync is something AMD has needed for a while now, and it finally puts them on even ground with NVIDIA and their G-Sync technology. According to reports, FreeSync will be on more monitors by the end of the year than NVIDIA will have G-Sync capable monitors, which is something else that is equally as exciting.
EDIT: looks like people are working on it:

One should note that FreeSync is not usable on the Windows desktop and needs fullscreen exclusive mode to work, which makes it incompatible with most video players. That said, the video player bundled with Windows 8.1 and Windows 10 is FreeSync compatible and the refresh rate will adapt to the video format, thereby ensuring perfectly smooth playback.
That's probably the quote I mentioned. Works with WMP in 8.1 and 10. I hope it will work on other players in the future.
Nvidia doesn't have a choice, I think they will hang onto G-sync as long as possible but ultimately will have to embrace F-sync.I hope nvidia moves to free sync.?
LOL@ Ryan's twitter. He seemed a little butt hurt, or is it just me? Either way funny stuff AMD breaking their own NDA.

Good review so far reading now.
The major scaler companies (Realtek, Novatek, and MStar) have all announced support for Adaptive Sync, and it appears most of the changes required to support the standard could be accomplished via firmware updates.
From the Anandtech review.
It looks like what I've been saying since A-Sync was announced is correct. Vindication feels good.
They really need to get down to 20-30hz.And because the minimum variable refresh rate is 48 FPS, and probably the worst judder comes within the 35-45 FPS range on a monitor with this configuration.
With the two working FreeSync monitors we have been testing over the past week or so we did notice ghosting of the animated images was prevalent. Our first monitor was the LG 34UM67, an IPS display, and thus we actually expected a bit more ghosting than our comparable 144 Hz TN panels. But we actually see a similar effect with the BenQ 144 Hz TN FreeSync monitor as well.
Looks like an LCD overdrive problem.
Nothing to do with FreeSync.
