Dell ST2210 21.5 Wide screen Display Full HD

But I'm just worried about the response time which is 5ms (typical). I'm assuming that's not that good for gaming?

Here are my preferences:

Budget:
$140-160 (I know not much)

Size:
20in+ (17-19 is fine but i prefer 20 inch+)

Response Time:
Not sure if 5ms is OK for gaming, so 2ms if possible

Online, or Offline:
I think the best deals are online, Online shopping isn't a problem for me

Max Resolution:
I would like Full HD 1080p, but 720p is fine, Again im not exactly sure

Style:
I dont care what it look like as long as it is a nice display and get the job done

Sound:
Doesnt need a speaker inside

HDMI?
I would like HDMI but VGA or DVI is fine

Bright?
I would like the brightest i can get for that price

Color?
I would like bright colors but whatever i can get

Places online?
Tigerdirect, Newegg, i don't really care whatever has a good price

New Refurbished?
I rather buy new.. But if it is refurbished and is like new then yes

Anything else?

I really need advice on the response time also

Thanks!

 

Dell has a 22 inch for $139, 23 inch $159 and a 24 inch for $199. All of these are 1080p and will serve you well.

 

I'm just wondering about the response time

 

Nevermind, I went with the ST2210 21.5 HD Monitor from Dell. They shot the price down 5 bucks this morning. Good thing i didn't buy it last night. Got free 3-5 day shipping Thanks for the help Clutch

 

I would get one as well but my desk is not big enough

I might get one this summer.
