For a computer monitor 1080p is a must, no matter what.
If you need a 37" and you want to best. The Toshiba 40XF550 is a super thin bezel design that fits in the exact same location as most 37" TV's, but happens to be 3" bigger as far as actual real estate. It is the smallest space you can take up and still get 1080p, 120Hz and all the decked out features.
If it has to be 37" for some other reason, I suggest the Sony 37XBR6, Panasonic 37LZ800 or Samsung 37A550. None of them have 120Hz, but they are probably the 3 best 37" screens out there.
