I thought this too at first, but if you look closely there are arrows pointing down at the lower right edge of the resolution selection menu drop down. I was able to select 1680*1050 no problem.
Got the last (as far as I could tell) Lego Batman X360 at the Target in Clifton, NJ for 12.48. They had a ton of Brothers in Arms: Hells Highway, GH: Aerosmith (disc only), and Tomb Raider Underworld.
