NVIDIA G-Sync Pulsar monitor - Asus ROG Strix XG27AQNGV

Ask about motion blur reduction in gaming monitors. Includes ULMB (Ultra Low Motion Blur), NVIDIA LightBoost, ASUS ELMB, BenQ/Zowie DyAc, ToastyX, black frame insertion (BFI), and now framerate-based motion blur reduction (framegen / LSS / etc).

Bonus pulsar shots at 300fps. My phone wouldn't do 1/75sec (1/4th of 300) so I used the 3 bar track at 1/100sec. Not sure if this invalidates direct comparison with other shots or not.

OK I couldn't resist and I bought this monitor :D
But I think i have defective piece. Check the screenshoot, there are some clear traces behind ufo. This is in 240Hz mode with Pulsar on at 2400 speed.When I open this test page for the first moment there are no traces but after few seconds they starting to appear. Second after second and traces are more and more visible. When I minimize the window white rectangle bars (those which help making proper moving photo) are still visible on desktop. It also happens at 360Hz, it also happens on different ufo speeds but the faster the worse it appears. It happens in pulsar mode, in ulmb2 mode, and without strobing. Latest FW 1.1.10.

That is LCD image retention, almost every LCD I have had does this with UFO test, except tn and oled

Your monitor isn't defective, I have that as well, only ever notice it on UFO test

Image retention, happens on IPS panels but this monitor is one of the more extreme cases I've seen. Its noticeable even on desktop with certain backgrounds.

Ok, so this is normal. I don't see such problem in games.But this retention might be permament, I mean like burn in with oleds?

Its only temporary, not like oleds which have permanent burn in risk. There must be some degree of variance between units but I think heat can make image retention a bit worse.

Are you guys not using adaptive brightness and cranking the brightness to max or something? I use my adaptive brightness with the brightness set to lowest possible with pulsar and I don't see any of that retention.

340 Nits all the time. Also no retention.

Adaptive brightness is too distracting imo. I think most people prefer the consistency of a set brightness level. Also, doesn't it introduce extra processing delay?
