hdmi output doesn't support 720x576 resolution on tx2

Hi All,

I want to know weather 720x576 resolution is supported or not for hdmi output? I tried setting it in Xorg.conf file but it got changed to 720x480 on reboot. any help is much appreciated.


Please be aware that the graphic driver on tegra does not allow user to put self-defined mode in xorg.conf. The mode can only be read from edid or device tree.

Hi WayneWWW,

Thanks for responding. actually there is no monitor connected. so we are forcing 720x576 resolution in Xorg file. can we force it in device tree? are there any other ways to do it?

Actually I am wondering where this “720x480” comes from if no display connected. Could you add this in xorg.conf and share the log with us?

#Add below option in /etc/X11/xorg.conf, 'Section "Device"'. Verbose mode logging will be shown in /var/log/Xorg.0.log
Section "Device"
  Option   "ModeDebug"

Hi shivlal12345,

Have you managed to get issue resolved? Any result can be shared?
