Hi song

there is a post where the author recommends to set width to 1360 due to IPU restrictions.

Enable 1366x768 LVDS screen on MX53 LVDS 0, Android R10.3.1 -blog archive

One can try this solution. It is for Android but may also work for Linux.

Seems there is no way to make it work directly in 1366x768.

Best regards
igor
