Yeah just found this thread: http://community.acer.com/t5/Monitors/XF270HU-Overdrive-and-firmware-bugs/td-p/405267

How is this still not addressed? They're just passing it up as normal behavior? BenQ came out with a fix for the XL2730Z. According to that Acer rep this monitor won't be getting anything like that, guess this one is out of the question now too. I think i need to take a break from the monitors/displays section, its beyond depressing as this point.

Just get a BenQ XL2730Z or some 21:9 and settle until OLED comes in, IPS is garbage for gaming today and it'll continue being garbage in the near future, TN has improved so much now that I can't see the difference in color reproduction after calibrating my XL2730Z compared to my XF270HU unless you force yourself into unnatural viewing angles, also the Motion Clarity on the BenQ without even using Blur reduction is so good.

I used to fee like my XF270HU was some sort of "Dynamic Resolution" abomination, compared to streaming services like Netflix that reduce the resolution from 1080p to 480p whenever bandwitch is an issue, I felt the same change when in my XF270HU there was rapid movement.

I think i'm just gonna pull the trigger on the Dell S2716DG which i believe uses the same panel as the BenQ or at least has very similar performance except that its Gsync. Its only $50 more than the BenQ and i'd be able to use VRR immediately instead of waiting on Polaris to hop over to AMD. Gonna wait it out a little for PCMs review of the Dell and then make a final decision. I'm on a korean 2795QHD right now at 100hz and while its pretty good at everything and i have no bleed, its not the best for competitive FPS and doesnt have VRR .

I'm not opposed to TN at all, i had a VG248QE and i loved that monitor especially after i made it glossy and gave it a proper calibration, and i've tested a pg278q before so i know how much better the 8 bit TNs are over the rest of em. I was actually blown away when the first swift came out, 0 complaints until i saw the really bad pixel inversion which was mostly alleviated with turning constrast down a tad, but it also had a big uniformity splotch in the center of the screen so it had to go back.

Only thing thats been concerning me about the Dell is the overshoot present on it as demonstrated in reviews and some videos. Maybe i'm making it out to be worse than it really is in my head and i wouldn't really notice it much in practice so theres really no harm in giving it a chance at least. Worst case scenario i send it back and lose out on $20 for shipping assuming it didnt have some other defects rolleyes.gif

That monitor is exquisite, if its anything like the BenQ the Overshoot Artifacts at PREMIUM or Extreme should be 5 times less than a XB270HU using maximum Overdrive as well, but also providing extremely low Rise and fall times for smooth and clear frame transitions, I'd say go for it, just a side note thought.

Sidenote: VR is all about latency and parallelism, it changes the rules on how GPUs should work, currently AMD utterly destroys Nvidia in VR by looking at the performance charts, if Pascal doesn't fix this maybe you shouldn't go Nvidia given your motivation seems to be driven by VR content, the Async Computing Engines in AMD's card do make a huge difference, adding to the VR Experience.

Acer says its enabled with free sync, but I'm not so sure. It's not 100% broken like Dargon says because you can get it to wrk with an an nvidia card and amd cards with no drivers.

I had a few days to play around with a friends XB270HU and i actually didnt have a problem with it. I used OD on normal which is the ideal setting as it has 0 overshoot, and no blur really either, just some color streaking which is very minor and arguably not as bad as blur/overshoot, but again i never really noticed it in normal usage. It also had no bleed, but the glow was of course there and that was always an eyesore when a dark screen would come up. The TNs have their own problems, but at least theres no glow, and it seems like you have more chances of getting a good sample.


Virtual Reality? I guess you may have confused VRR (Variable Refresh Rate aka freesync/gsync) for VR. I'm actually interested in VR, but not this first gen of products about to launch, too low resolution and only 90hz. I'll wait for 2nd or 3rd gen and by then both GPU vendors ought to have good performance in VR titles.

Yes, I confused VRR with VR, how silly of me tongue.gif

Regarding VRR, Gsync and FreeSync are exactly the same thing except for a few differences in behavior. I don't know if this will matter to you but.

1-Freesync have the least latency compared to Gsync when both have Vsync Disabled, up to 12ms less.

2-)Gsync have the least latency Compared to Freesync when both have Vsync Enabled, Up to 8ms less.

3-) Freesync have the least latency compared to Gsync when running a game at 200 FPS (Perfect for input lag) with Vsync Disabled on both Gsync and Freesync, 14ms Average.

4-) At 45 FPS Gsync have the least latency compared to FreeSync with Vsync Disabled on both FreeSync and Gsync with an average of 19ms less latency than FreeSync

5-) At 45 FPS FreeSync have the least latency compared to Gsync with Vsync Enabled on both FreeSync and Gsync, with an average of 17ms less latency than Gsync.

Just something to consider.

Any source for that? I'd like to look into that a little more

What? Overdrive? Fall Times? Motion Clarity? VRR?

I'll assume its VRR, which means you should check this benchmark from LinusTechTips.

If you care to check the setup watch from the beginning, if you want to see the results right away, start at minute 11:40

No the VRR latency differences between Freesync/Gsync
