Hi,
My Jetson Nano has only one resolution (1920 x 1080) after reboot. I use xrandr command and show me the error xrandr: Failed to get size of gamma for output default.
How can I fix this problem?

Hi,
Are you able to try other TVs? It should read EDID from the TVs. Probably it fails to read all modes of the specific TV?

I haven’t try other TVs, but it works before :-( I ran CuDNN test sample, so is it because that?

Hi,
cuDNN test sample should not have impact to this. Suggest you try other TVs for comparison. We can clarify if it is something wrong in system image, or the specific TV.
