This is a valid Area 51 research-related question so I've moved it there;
It's also related to
Vicious Cycle Effect involving higher resolutions and wider FOV. You have more time to track moving objects onscreen before they disappear offscreen.
Informally, we found the interval to be approximately 0.5ms (the approximate time, during a saccade, to identify that a moving object has more motionblur than a stationary object), though we need to experimentally verify this number more closely. It's roughly the same order of magnitude as this.
So at 1920 pixels/sec on a 1080p display, a moving object disappears offscreen in 1 second on a 1080p display. At 3840 pixels/sec, a moving object is visible onscreen for only 0.5 second, and it's practically almost too fast of eye movement + almost too brief to identify whether or not there is display motion blur.
Experimentation will be needed to refine this number, but it helps the science of determining a displays' theoretical retina refresh rate (for sample and hold), where persistence blur is no longer perceivable by the said human.
So retina refresh rate for a 24" 1080p might be barely above 1000Hz-ish for a near-0ms GtG tech like OLED, while retina refresh rate for a 180-degree 16K VR headset is well over >10,000 Hz.
For sample and hold and 0ms GtG (superlative refresh cycle compliance, like
Blur Busters Verified displays), Motions at up to about (2xHz) pixels/sec will generally looks tack sharp. So for a 480Hz OLED, you can have motionspeeds up to 960 pixels/sec looking tack sharp.
I'll probably add a new piece to the
Research Portal later in 2024 about this topic;
