You sure HDMI-0 is the correct output name? /sys/class/drm will tell you that.

how can i check /sys/class/drm ?
that is the problem .. i can get a 1080p/50 hz display.. but menus and some part of the screen does not fit the screen resolution.

Err, how about "ls /sys/class/drm"? (I'm actually not kidding with that)

Also, if stuff doesn't fit, it means overscan is active. It could be either the tv doing it or the graphic card.

"ls /sys/class/drm"
card0  card0-DP-1  card0-HDMI-A-1  card0-LVDS-1  card0-VGA-1  controlD64  version

So shall i write HDMI-A-1 as card?

Yep.

Which graphic card is it exactly? If it's radeon, and if you don't mind compiling your own kernel, revert this change, it might help with the overscan (only affects X though, not the console): http://git.kernel.org/?p=linux/kernel/g … a481351b44

Configure your video player to use something other than xv for output. Welcome to the wonderful world of the ATI blob. Where things stay crashy for many months.

Be sure your TV has overscan off
