[mythtv-users] overscan problems with nvidia 8400 GS

[Tortise]

Hi Mike

Out of interest what is the model and brand of your TV?

I know some more recent Samsungs, for example, display all the pixels using a VGA input.  It is a variation of some smarts towards 
answering the problem and if your set does this then you are ahead of those whose sets don't correct at all, however it would be 
better if the option was available on all inputs.  Your TV is almost certainly expecting to display a video image that your 
manufacturer thinks should be overscanned on all inputs - except the VGA - which is clearly expecting a PC's output.  They have 
presumed that you would not wish to display a PC image on any of the other inputs.  What did their promotion literature say, this 
may be consistent with the promotional material and not overly misleading?

Interestingly, I also watch primarily Freeview. My TV has a VGA input as well as
two Scarts and two s-video inputs. My mythbox is connected to the VGA input usually.

I have, however, tried it both with a VGA-to-Scart adaptor, and with an S-Video
to Scart adaptor. With VGA, what you see is definitely what you get, it behaves
exactly like a 1366x768 computer monitor, pin-sharp. With other inputs, there is
obvious overscan and the picture is softer, although still acceptable to the
layperson's eye. I don't know whether that's a function of the video driver or
if the TV is reconverting the picture to overscan it.
