we are trying to use the display port with the following resolution: 3840X1200 , 30Hz or 60Hz.
Currently it appears that this resolution is not supported:
we used xrandr command with -newmode arg. (we extracted the timing parameters with gtf command).
when we add this resolution with -addmode arg, it fails. maybe it because our screen not support it?
- is there any fix to that problem? we still want to use this resolution.
- is there any list of supported resolution by our monitor? do we need to update this list manually or maybe use xrandr to do it automatically?
we found in Linux_for_Tegra\source\public\kernel_src\kernel\kernel-4.9\drivers\gpu\drm\drm_edid.c some timing parameters related to specific resolutions but we dont know if we need to change it in order to fix our problem or not.
