[mythtv-users] Xorg nouveau driver vs. nvidia-driver

[Ram Ramesh]

Hi,

   I am running mythtv 31-fixes on Debian Buster (10) through 
deb-multimedia backports. I started with Nouveau driver for Xorg as that 
is the default in Debian buster.  After testing a while and making sure 
that it works, I added nvidia-driver.  While mythfrontend seem to look 
tiny bit better, I see that gui is not fitting due to overscan on TV.  
It was perfect with nouveau driver and overscanned on nvidia-driver. 
Another thing I noticed is nouveau drive gives me 1920x1080 at 120hz 
whereas nvidia does 1920x1080 at 119.88hz. Not sure if nouveau is rouding 
or giving me a true 120hz. I do see that my TV takes a while when 
switching from another source to mythtv host when in 119.88hz rating. 
Given this,

Is nvidia-driver known to be superior that I should try to keep it and 
adjust frontend gui resolution to make things fit or should I simply 
switch back to nouveau driver?

Also, overscan is a general issue even with Xorg, and fixing gui 
resolution will not make Xorg better. I will have to fix Xorg overscan 
somehow. So, I prefer nouveau over nvidia in this aspect.

Any help suggestion in improving what I have is much appreciated.

Thanks
Ramesh
