Problem with a 240hz VA panel monitor

[netulla]

Hey,

So i have this motion blur "Double Strobe Artifact" on my screen, so is there any way to remove it?

My monitor is a AOC C27G2ZU/BK 240Hz.

If you are recording with stationary camera and the ufo is in motion you are basically simulating a stationary-eye-moving-image (which I assume is what u did here). In this specific case ufo would look blurry in real life. So the goal here is not to remove the double image, but to add more of the images more densely so it could blend into continuous motion blur. Essentially the reference image is no longer a clean ufo, but a very blurry one. The confusion must of came from too many clean looking ufos online, which on some displays can be achieved, but with moving-eye/camera-moving-image. If you're trying to get results similar to some of the reviewer's, you'll want to track the ufo (move the camera) and use Ghosting/Pursuit Camera Test.

For this combination of content movement and eye movement, unfortunately all displays look the way you captured it. This effect is called phantom array or stroboscopic effect and is caused by insufficient sample rate (refresh rate & frame rate) or flicker rate. In this case it's low sample rate that's causing it. This is pure proof 240 Hz is not high enough to accurately simulate retinal persistence (to not create gaps in retinal persistence).

Even 1000 Hz fps is not enough. Only way to fix it is with super ultra high sample rate. More precisely, it needs to be as high as the speed the content is moving at, so each image (frame) could have its own pixel to create a continuous blur. If in this case ufo was moving at 2400 px/sec you would need 2400 Hz 2400 fps. But of course that is not the fastest something can move at. Blur Busters have estimated that 10 000-20 000+ Hz fps should be enough. Although it can get higher/lower depending on a lot of other factors too. Until monitors and gpus reach such high rates, this artifact is unfixable.
