I am new to this forum and i apologize if this has been already answered and sorry if the i couldn't explain it better but I need help with using a custom resolution for my monitor in Ubuntu(19.10) linux.
My monitor is a bit damaged i guess and cannot output at 1080p 60hz (but somehow can @65hz and 62hz) so in my windows i used amd's custom resolution setting to apply a 65 and 62hz refresh rate (which work flawlessly) at 1080p on windows. On linux I used both cvt and gtf commands to output a modeline and use it with xrandr but none work. I'm trying to figure out what exact settings does the amd driver put to make the monitor work, and some settings it does provide info on I can't seem to make them work on linux. Here are the settings i took from the amd radeon settings on windows I hope they can be of help:
-Horizontal Res: 1920px
-Vertical res: 1080px
-Refresh rate: 62Hz
-Progressive
-Timing Standard:Manual
G.Pixel Clock:153450(kHz)
G.Refresh Rate: 62.000(Hz)
H.Timing Total: 2200
H.Timing Display: 1920
H.Timing Front Porch: 88
H.Timing sync Width: 44
V.Timing Total: 1125
V.Timing Display: 1080
V.Timing Front Porch: 4
V.Timing sync Width: 5
H.Timing Polarity && V.Timing Polarity are Positive
These are the the settings i guess that work on windows but I can't seem to be able to use this on linux. If someone can help me be able to use this or maybe knows how to get more info on windows that would be greatly appreciated
