Which MultiTouch Monitor To Buy?

By on 2/20/2010

Last week, I pondered the state of multitouch with XNA. And I mentioned that I was considering buying a multi-touch enabled monitor from Dell. Well, over the last few days I have been shopping around on line and I've been pleasantly surprised to find that there are several others on the market.

Acer t230h

Dell SX2210

HP L2105tm

Because of the technique they're using to do finger tracking, all the monitors only support two touchpoints at a time. Makes me wish that a homegrown solution like the optical webcam based solution I experimented with a while back was more feasible.

The HP L2105tm is the most inexpensive offering, but also, seems to have other deficiencies such as a slower response time than the other two monitors. The Dell monitor is nice because it has a built-in webcam, which is something that I've been interested in having for a while, but is ultimately secondary. The Acer T230H is the one that is currently capturing my interest; it's the largest monitor of the three at 23 inches, and according to the specs has the best contrast ratio.

So, does anyone have any suggestions on which monitor I should go with? My primary goal is to have hardware that I can program multitouch enabled XNA games with :-)
