Dear Nouveau developers,
I encountered this problem using Artix Linux:
https://forum.artixlinux.org/index.php/topic,5859

On 2 laptops (Dell M4400 and M4500, Nvidia graphics using Nouveau) which have a 
VGA port, a Maxim MX11-LCD15 TV with a VGA port stopped working, also another 
Panasonic TX-26LXD500 TV using VGA. These are older TV's, from the 2000's, I 
guess the EDID might not be entirely compliant with modern standards. A newish 
AEC monitor (not TV) did work with the latest kernels so not all VGA connected 
monitors are affected.

>From searching online it seems that there are numerous reports of monitors 
>stopping working with the 6.2 kernel in various distros.

This is the commit where the problem apparently first appears:
