Sorry to dissapoint you mate but for 200 to 250 dollar it will be hard to find a good gaming monitor, The prices you pay you will be seeing the backlit display in the corners (higher contrast on the outside lower in the middle) Noise and low resolutions. However you could get a ok-good Normal monitor at around 17-19 inch. But im looking to buy a 20-24 inch as i need it for work and gaming and a good one is setting me back 400 pounds (between 700-900 dollars).
Thanks. Keep shopping and you might find sumthing reasonable especially as the USA is about 1year infront of the UK in Tv and TFT monitors. Maybe they do sell good monitors for that price over there ??
Many Thanks (Dell and LG's Flatron are particulary good)
