heres something you need to look at, to see if your computer monitor will work
http://playstation2-linux.com/sog.php your pc monitor has to have SOG (Sync on Green) which comes on more recent monitors. also xbox versions 1.4 up will not work either. well after reading the page i found that neiher my xbox nor monitor are compatable
, so i will see about finding a better tuturial for you
maybe if possible try to find one of these at a local store, maybe pawn shop if possible because its supose to work with all xbox's and all monitors
