I am not sure that it is television related.

I have a motherboard with integrated nvidia 8200 graphics. Initially, it 
displayed BIOS and console via DVI on my television. However, at some 
point (apparently I did something via software, but I do not know what), 
it stopped displaying BIOS and console via DVI on the same television. 
In both cases, the display worked after Xorg started. Therefore, the 
hardware went from working to not working on the same television.

I have thought that at some point I would boot the system using Windows 
in order to see whether or not the Windows drivers/software might fix 
the problem. However, since it continues to work via the HDMI interface, 
  it has not been a high priority.
