360 vga green screen
 

there are some smart people on here so i thought i would ask.
i have brought a toshiba 27wl56 tv to go with my xbox 360http://www.home-entertainment.toshiba.co.uk/consumer/products.nsf/specs/lcdplasma-widescreenlcd-27wl56?opendocument.
on the specs page it says the resolution is 1280x720 i am using the vga lead. the only thing is when i select 1280x720 on the xbox options i am getting a green screen. all the other resolutions work fine.
what is happening here???????????
if knowone knows what is he next best resolution to put it on.
cheers in advance.

Have you changed the input type from RGB to component or vice-versa on the screens menu for the VGA input? Mine goes pink!! LOL!
