I have the Acer H213H 21.5" Heres my desk. Sorry its messy, we just moved in last month. (yay bought my first house)
Pc is hooked up through vga, xbox through hdmi. Pc sound is through the Sound Blaster Live on 2.1 Boston Acoustics. (also buying a new gaming rig soon )
I dont want to lose the 1080p quality of the video. I do have a Xbox DVI cable. Not sure how to split the sound out...
