My wife got tired of me playing the 360 in the bedroom late at night while she's sleeping. So I bought a vga cable for it and moved it to my office. I have dual Dell 21" widescreen flatpanels setup on my computer. So my left monitor uses a dvi cable from my computer, so I plugged the xbox360 into its vga port. I set the 360 resolution to 1280x1024 and all I have to do is hit the channel button on the monitor to switch from PC display to 360 display. I ran the sound output from the 360 into my PC's line-in input on my soundcard, so my 360's sound plays thru my PC speakers.
Xbox 360 looks killer on the widescreen monitor, and the sound is great coming thru the PC speakers + subwoofer. I played Elder Scrolls for 6 fucking hours straight last night
