Has anyone came up with a solution to this problem..I used to get full 1080 resolution with my Insignia 32 inch TV so I know my hardware can push the signal, I am running a Radeon x1550 graphics cars 3200+ processor on a 756 chip set 64bit version of Ubuntu 13.04 your help is greatly appreciated and you may or may not be compensated for your time
