Or you can get any old monitor and a display port adapter.Finally got approval to get a Surface at woek, need to know what lcd monitor has DP input and output. What are you guts usinf.?
Those Dell Ultrasharp monitors are nice ones, I'm using this one Amazon.com: Dell UltraSharp U2412M 24" LED LCD Monitor - 16:10 - 8 ms: Computers & Accessories, it's great. You want 16:10, if you can help it.HDMI standard mainly used throughout customer devices only supports FHD.
Duspplay Port in the SPro Spec goes up to 2560*1440p
As a current Dell U2711 woner i would recommend a Dell U2713HM
+1I just got a Dell UltraSharp U2713H Monitor. I'm running my Surface Pro at 2560X1440. It is awesome. With a Bluetooth keyboard and mouse and external HD thru the USB, it's hard to believe the SP is not a desktop computer. But I just unplug and take it with me, and whatever I was working on is still there with me on the SP.
