Toshiba lsptop not filling up monitor hdmi

[miltonarc]

I have a Toshiba L755 Laptop with Intel Graphics and Media Control Panel. I hooked up the laptop via HDMI cable to a TV monitor. It worked great, but afterwards the screen will not fill up. I can't adjust the overscan and am stuck.

Select configure resolution settings on the Tv/Monitor..
Complete a windows update.. this may update your video Intel Driver.
Try using a Vga/Dvi cable and see if that fills it up. - Temporarily
