Any ETA on the firmware update?

Also does anyone who gets eye fatigue or any other symptoms from OLED screens also get it from Pulsar? I can't use OLEDs at all because of what I suspect is PWM flicker. If I do get a pulsar monitor, I hope it doesn't have the same effect on me as OLED in regards to causing eye fatigue/dizziness related symptoms

I have found the Pulsar screen a lot easier on my eyes compared to my OLED. I would get eye fatigue with OLED and sometimes I would get dry/red eyes with really long sessions.

With Pulsar I can game all day and my eyes are fine.

Maybe it’s because I move my eyes around more with the Pulsar screen, I’m not sure. Using the oled again isn’t pleasant.

Even with the ambient light sensor off on the pulsar so it gets super bright, no issues.

If it was a QD-OLED I've heard people get headaches from it, I'm assuming it's because of how they filter blue light into the other colors using the quantum dot layer that causes the eye fatigue, either way I can agree pulsar is easier on my eyes than a QD oled if that's the case, on my WOLED however it doesn't give me any less eye fatigue but I never had eye fatigue to begin with on WOLED (and neither on pulsar!)

No. Human hand shakiness.

When DPI is high, micro shakiness from hands can become visible, and some paid esports athletes use 400-800dpi in CS2 to prevent that.

thanks very much!

It's becoming less necessary to stay low (400-800) especially if you need different kind of competitive advantages that 1600dpi and up brings during extreme-Hz and/or strobed operation. Low DPI sabotages motion quality on ever-higher display refresh rates during slow-to-medium-speed mouse movements.

Yes it’s a QD OLED, AW3423DW. I find the Pulsar I get a lot less eye fatigue than CRT too.

I have discovered another annoying bug on my Asus Pulsar screen. For reasons discussed here I am running the screen on 240 Hz since a while. Not sure if that plays a role. But since a few days now, when I leave the computer for a while so the monitor turns into standby, when I return and move the mouse, the display starts only with ULMB2 mode. Gsync is on and working. I have no chance to activate Pulsar. Not by changing resolution, not by switchen gsync off and on again, it remains ULMB2. And its clearly visible to me.

What does help is a Windows restart or Turning the monitor off for a second.

I dont think I had this behavior when using 360 Hz mode...

However, I hope this also gets adressed with new FW.

I just got the Acer pulsar monitor and it's pretty good. Better than I expected. I can very clearly tell a difference with pulsar. There is some very slight eyestrain, noticeable enough for my eyes to feel "relieved" when pulsar is off but it is nowhere near as bad as OLED. With both woled and qd oled, I found myself having to close my eyes and take a walk to recover. And it's nice I can simply turn off pulsar and use regular gsync just in case.

One major downside I did not expect at all was that the Acer monitor's stand is really bad. You can't set it atop any books for example or really increase the height in anyway or else it will fall over. If you're someone like me who likes their head tilted up for comfort while gaming, you might have to invest in a different mounting solution.

Another downside is that you can't seem to use custom resolutions/refresh rates at all. Pulsar will simply be greyed out in the settings. I prefer setting my monitors to 180hz with CRU for various reasons. (games seem to be less smooth and more stuttery when I do 180fps cap on 240hz mode vs 180fps 180hz. I'm not sure why, it's very strange).

Also, does anyone else notice a color change when pulsar is on? I understand that a brightness increase is to be expected but also the colors seem a bit more saturated in a distorted way when pulsar is on. Not sure if it's unique to the acer model, but there are separate brightness settings for pulsar off and pulsar on in this monitor so I was able to somewhat tune pulsar mode's colors and brightness to match pulsar off but it's quite strange that the colors are affected too.

What's the reason your both using it in 240hz mode?

With 360 Hz the display signal is compressed via DSC. On some displays (not just pulsar, also some Asus OLEDs) this leads to black screens when switching to full screen and alt+tabbing. Not just that. It even blacks out in the middle of some games if you run them on exclusive full screen. Which is the only option on some older games or emulators if you dont want to have any menu bars.

According to some reddit posts, this is a problem with RTX 30 and 40 cards (4070 on my end).RTX 20 and RTX 50 cards as well as AMD cards do not show this behaviour (AMD of course is anyway not an option with pulsar but they seem to work fine on OLEDs with 360 Hz, qhd and DSC). The fact that RTX50 cards are DP2.1 should not matter as the display is just 1.4 but I have read somewhere that RTX 20 cards have more "conservative link training"... whatever that means, and RTX 30/40 cards are more sensitive to extreme pixel clocks. RTX 50 cards have the latest DP2.1 PHY which could help. And the fact that I havent found ANY reports that this happens there... is enough for me.

Long story short... noone can really say why it behaves like this. But with 240 Hz we assume (although you cannot really confirm this through Nvidia CP or display OSD) the signal is not compressed, hand shake works better, no more black screens. Of course when switching to exclusive full screen its also black, but for a much shorter time and it does not black out while gaming.

If pulsar works as it should (1% lows are good)... a well strobed 230 fps picture anyway looks almost identical to a 340 fps picture.

But as stated above, I have now discovered this new thing regarding pulsar being turned off when returning from standby. I will not switch back to 360 Hz for now anyway (until i upgrade to a rtx50 card or newer), so I just hope this will be fixed with a fw update.
