I'm the same...need 1400x900. Microsoft should listen to us, I think this widescreen lcd problem will continue to grow and we are the ones spending hard earned cash on xbox 360 products. If they don't look after us, their customers, with a simple upgrade to resolution selections to cater for 16:10 monitors, Microsoft will continue to piss off a lot of their most devoted consumers and this will lose them a lot of $$$. The customer is always right and this thread is an indication of what we need to keep spending our money...
How about 1920x1200! Almost all 24" LCDs use this as a native resolution, so stretch the 1920x1080 image to fit the screen. I'd rather take black bars top and bottom over a tall/skinny Marcus Fenix...
My wife says that she wants the resolution of 1680X1050, or else she will kick me of her house. Then i'll be mad at ya, MS! And i'll send the MS-13 click to ya in Redmond.
