Re: Resize on Linux
-> GPU-0 (card #) -> DFP-0 / DFP-1 (TV name#) -> Flat Panel Scaling
[x] Force Full GPU Scaling then select Aspect Ratio Scaled
-> X Server Display Configuration -> Display
then select your TV and change your resolution
(you might need to #1 add your TV as a second display, #2 then disable your first display, #3 re-adjust the resolution of your TV)
do those entries exist for you ?
