So I work at Best Buy and I'm choosing from either a 21.5"-23" LED Monitor, a 21.5"-24" LCD Monitor, or anywhere from a 22"-32" HDTV, 1080p on anything 22"-24", and 720p on anything 26"-32". I recently bought an Ati Radeon 5770 and would like something that will give me the best picture with that card. It will be used only for gaming purposes ^^
The pixels on TVs are reletively large compared to the ones on monitors so you must sit further away.
LED monitors are LCD monitors. They are the same thing, I wouldn't pay more for one but if you can get one through an employee discount for cheap then go for it.
I won't go for anything less than 1080P personally. 720p has half the pixels of 1080p so it can look pretty blurry up close. I would go for a 24" monitor since the 5770 can easily drive 1080p on medium settings.
Well a 32" while sitting close to it is pretty intense... My eyes fixate in the middle usually and I can't 'see' the whole screen without looking around. I'm thinking that is a bit overkill, but the 24" 1080p is 200 dollars. The only bad thing is the contrast ratio is only 2.5k:1, and the frequency is 60Hz. The monitor on the other hand has a contrast ratio of 5 mil:1, and has up to a 75Hz frequency, and it costs 180... Personally 24>21.5 and it's only 20 bucks more.
