Hi.
Noob alert here! I have searched and tried a few things that seemed related but nothing's worked for me.
I have a GTX8800 connected to a Panasonic 50PX60 plamsa DVI -> HDMI.
The problem is that when playing letterbox films in VLC they fill the plasma (ie, they are stretched vertically). When playing 16:9 it all works as it should. I am using Nvidia's latest drivers and it's set up as a Dual display, not clone, etc. Changing ratio/crop settings via the "a" and "c" keys has no effect on the plasma.
Any help appreciated!
