Was working on a screen burn tool

Post by taisel » 03 Jan 2021, 05:54

Looks like it can be used to figure out how bad or funky some monitors are, as a tangential purpose.

It's rotating which singular sub-pixel is lit per pixel.
The slider controls how fast it's changing the pattern on screen.

It's also interesting for the fact that it shows up entirely wrong at max speed (slider set to the left) on some monitors with overdrive or fake bit depth via temporal dithering, which is why said slider even exists (So the pattern can be adjusted to alleviate blurring itself ruining the subpixel bursting).

Thanks for posting this! It does produce interesting artifacts on some models of monitors. Including potential image retention.

I actually have a hidden TestUFO image retention test tool, but I haven't posted it publicly -- I don't want users abusing this or to scare people about TestUFO damaging their monitors.
