I just happen to be testing surround view in my new rig today with 3 monitors. The one on the left is Primary with the "Start" button.

Left to right:
*22" CRT, 17"analog LCD, 55" HDTV RPTV Widescreen.
*1280x960 85Hz, 1024x768 60Hz, 1920x1080 30Hz
*1)X800 XL Primary VGA, 2)Xpress 200 VGA, 3)X800 XL YPbPr
Surround View driving 3 analog displays with seperate Refresh rates and resolutions.
Quake3 running on #1, FOX analog with Sapphire Theatrix using MPC on #2 and MCE displaying "Less than Perfect" in HD using the HDTV Wonder in 1080i.
I've had it up and running for a few days now, and so far, I'm impressed. Nice feature set for a decent price and some functionality not easily reproduced by other means is handled easily.
Edit: Fixed link and added info.
