help needed with prject gotham on the Xbox 360

I'm trying to run this game in High Definition on me Viewsonic 19" tft.

Every other game looks great except project gotham it stretches the screen and the cars look short and wide really odd, i've noticed why it does it.

on all my other games it puts a black strip accross the top and bottom of the tft and does it in project gotham right though to the point of the game loading as these arn't there it stretches the screen and makes it look so poo i can't play it.

it's nothing to do with my pc as my pc only handles the sound it plugs directly into the back of my tft, i've also tried loads of different resolutions in the xbox set up screen and makes it look different but not right, Project Gotham was probably made with the intention when running in high definition while played on a wide screen tv or something, i was just wondering if anyone else has had this and found a fix i'm pretty sure it's a feck up with the game as it's only that game and it's fine until it gets to race time the bands are there.
