Nah.. Monitor will suck coz consoles is not designed to output to monitor. All those 3rd party VGA converter only gives sub-standard quality compared to a CRT HDTV. Furthermore, all monitors are 4:3...lagi not suitable for XBOX360.

If got budget, go for a good quality LCD/PLASMA with decent resolution. Most LCD is around 13xx x 7xx resolution max, but i guess it's good enough.
