This is a decent one with display port http://www.tigerdirect.com/applicati...92686&csid=_25
This monitor seems to have pretty nice bezels which is important for eyefinity. Although you Hp seems to be the same just smaller so it should have a Display port already.
The only thing you need to realize is the stress it puts on GPU's. Your 5870 even oc'd will not be enough for a game like crysis or similiar game in eyefinity. You will need another card for sure. I am in the same boat with my 6970 that is not up to the task.
If you got 2 more monitors like yours the total res wont be as much though so that may save you a little since your total res will be aroun 5040x1050 I think.Edited by Topgearfan - 5/3/11 at 4:26pm
