For most gaming you want to look for a monitor that has a low response time, under 5 ms, less is better. That is essentially how fast the monitor can change a pixel from one color to another color. Slow times create ghosting effects. For $250 you are going to get a much better screen by buying a computer monitor vs a TV. I personally use an ASUS VS-247P-H (23.6 inches) and I really like it. The colors are nice and vibrant. I would say the biggest downside is the screen is pretty bright, and as you turn down the brightness if you like to game in a dark room, the colors start to lose their vibrancy. There is also the VS-248P-H which is a full 24" monitor. Both are available on Newegg for under $200. They can be found for around $150 on sale/rebate fairly often.
