I am currently running three 19" monitors, and I am looking to get a larger center monitor. Can you help choose a monitor that would fit between the two 19" monitors

The two side monitors can be rotated if necessary
I have the three monitors are a stand so I only need to be concerned about the monitor measurements w/o the stand.

I am looking a good price on a monitor for gaming. Any help is appreciated..>>>

the measurements are as follows

19.0" diagonal
monitor measures
16.25" horizontal x 13.3125" vertical

viewing area:
14.8" horizontal x 11.9" vertical

I would like to go to a wide screen yet maintain uniformity with the viewing area. (or atleast as close as possible).
