I think you mean 37" TV, a 37" MONITOR would be very very expensive. It's a small difference, but there is a difference.
I just picked up a 37" 1080p TV, and find it works well with games. Not sure what you mean if it's a good monitor though. Without a part number no way to know really. Generally 37" LCD with 1080p will give you a nice sharp image, more so than a 42" or larger.
