Plasma/LCD as monitor

[Recliner]

The resolution on a TV is going to suck. You want at least 1600x1200 and I don't think you're going to get that from a TV.

The other thing you need to be concerned with is the difference in picture quality between you're monitor and what ever you plan to use for your second monitor. I've tried dual monitors without a matched set and it bothered the crap out of me. I want thing to look the same on either monitor. That's why when I decided to get a second monitor I bought the same model as my first.
