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.
The ‘good’ vero log (on the bedroom cable and TV) is https://paste.osmc.tv/siququdite
