How is this for a monitor?

seems a decent price to me, only issue is it's resolution - 1366x768 pixels. How will that be for gaming?

Honestly, it would make for a pretty sub-par monitor. Its supposed to be a TV,and a pretty bad one at that.

Get something like this:

I game at that res and I don't plan on upgraded to a 1080p monitor for a while anyway (my main tv is 1080p and I keep meaning to try the PC out on it), sure its not as high res but I can compensate by running in higher settings with AA and AF up. The one you are looking at has a 6ms response time according to the site so it might make a good monitor if you want to use it for consoles/tv too and you have the bonus of speakers inbuilt, but you could probably save money just buying a dedicated pc monitor.
