My max resolution is 1080p , 1920 x 1080 and my lowest is 720p , 720 x 576.
I'm currently using 720p 1176 x 664.. but there's black borders and I'm trying to get it to stretch to the end of my monitor but yeah you know what I mean?
1280 x 1024 is the recommended but it is a bit stretched out past my TV.
just try a few screen resolutions till you find the one your happy with, it will let you try the resolution to see how you like it, if you don`t click to confirm you want it, it will just keep the old resolution
just noticed you connecting dvi to hdmi, does you have a vga connection, you could also try connecting dvi to vga, or hdmi to hdmi, i have know some people to have problems mixing connections
