The 3D resolution modes are listed separately from the 2D modes. If your device is not getting the EDID from its display we need to specify the 3D modes in a file called disp_cap_3d. But we don’t know what modes your TV supports unless you can connect a good vero to it and get the logs.
If you are sure this problem started only when you upgraded to 19.3, you could reinstall 19.1 from the August 2021 release.
