While testing 1200fps camera I've noticed strange refreshing from bottom to top at lowest case (7,5ms).
Monitor is Asus PG278Q. Refresh rate is 144Hz. 1200fps capture. Logitech G100S (500Hz). ezQuake with stable 1200fps.
LED connected to right mouse button and that button binded to changed crosshair color to green. Left mouse button changes crosshair color to black.

I saw such from bottom to top update only at ~1-5% of measurements.
Captured height of screen is about 20%.
Is it ok?
LCD screen refreshes not from top to bottom?

Probably because you don't have VSYNC on.

screen tear, unless you v-sync it you will always get them.
