Dealing with custom resolutions on Linux.
Recently I've got a new LCD monitor+TV. Even though It worked without a problem in Windows, Ubuntu [16.04] failed to recognize it's native 1080p resolution. I've googled around and found a way to add a custom resolution using xrandr. But it didn't really worked for me. I've spent hours trying to figure this out and thought I should write this down on somewhere how I got this monitor to work on Ubuntu. Basically what you have to do is open terminal and enter: $ cvt 1024 768 60 // horizontal-resolution vertical-resolution refresh-rate which will give you a result like this: # 1024x768 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz Modeline "1024x768_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync Copy the output after the Modeline and paste it after xrandr --newmode As an example: $ xrandr --newmode "1024x768_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync Then enter: $ xr
