Ok I realized my mistake and fixed it (See below). However the TV doesn't support that resolution. So it appears, I either need to upgrade cards or stay at this resolution. So the question is now, video card recommendations. I just want something that will take advantage of the greater capabilities of the TV.
IME, 16:9 TVs generally don't support 16:10 resolutions (e.g. 2560x1600). Did you try 2560x1440? HD6450 works with 2560x1440 here.
