After some testing, in my experience, the higher the blanking (especially the vertical blanking), the more the screen would be prone to artifacts (LCD inversion, purple color glitching, scrolling horizontal lines). With my model XL2430, the lowest I could go with the timing values were:Amatureweeb wrote: ↑27 Jun 2023, 02:22Another note that might be useful: if you reboot from OC resolution sometimes it would not boot back normally, all screens go blank and no KB response; sometimes it even persists and i have to reboot in safe mode; setting it to natural 120hz solves the problem.
Might be my gpu (1060) issue
front porch 18 |2
sync width 32|2
back porch 8 |6
blanking 58|10
But while I used this, sometimes the screen would not wake up after going to sleep and the monitor would report that there's no signal. Curiously, this also works, where the blanking is the same, but I decreased the back porches and increase the front porches and vertical sync width, and if I tried to go lower than 58 horizontal blanking or 10 vertical blanking, the screen would go black, be glitchy or display 640x480@60:
front porch 24 |3
sync width 32 |5
back porch 2 |2
blanking 58|10
and didn't have the wake up issue anymore, maybe a front porch that is too low can be the culprit, you could experiment if you want.
