I've just bought a new TV yesterday, Toshiba 42X3030D 42" 1080p. 
I have my 360 plugged in to it using the official VGA Cable and the picture is fantastic when running in 1360x768 but when I try changing the resolution to 1920x1080 the pictures goes all strange with odd colours.
I'm not sure if the problem is with the TV or Xbox 360.
Anyone know of any settings that need to be changed for this to work.
Thanks
