Re: Desktop is blank - mouse can go off the screen
Your HDTX is in an 'overscan' mode where the top, bottom and sides are 'trimmed'.
You have two options:
(1) The TV may offer a 1-for-1 1920x1080 mode (mine does and I am typing this using that TV as the monitor).
(2) Your other choice is to set over scan compensation This create a 'black frame' around your desktop so all the menus are visible.
Option 1 is best (check your TV manual or <if male> fool with the TV settings).
Option 2 has to be set in the setup screen your proprietary drivers installed. You did not mention the brand of graphics card you are using.
Look at all those flashing lights! I'll take one!
