Acer T230H bmidh 23-Inch Wide Touch Screen Display - Black

Overall, I highly recommend this product to potential purchasers.

I bought this product from an Amazon competitor because I needed it quickly and it was not in stock. Of course, I paid more for both the item and shipping (about $400 total).

Pros: 1) At the time of purchase (October 31, 2009), the Acer T230H is the largest multi-touch display available.
2) It brings out the multi-touch capabilities of any Windows 7 laptop/desktop.

I had difficulty getting the T230H to recognize the lower left calibration corners using a stylus from a Windows XP Tablet computer. I canceled calibration and used the factory settings.

I just purchased a new computer with Windows 7 and wanted an nice High-Definition screen to go along with it and settled upon the Acer T230H.

It does however work with the back of pencils, pens, corners of paper, tops of water bottles, actually just about any solid object can be used to interact with this touch screen.

Well I almost sent the monitor back thinking it was for Windows 7 only. After much internet digging I found a forum that gave the answer.

Acer T230H XP Drivers can be found on HP's site. Here's how:
With usb view utility I checked the VID=0x0408 and PID=0x3000. Looking up these ID's tells me it's a TACTION Touch screen by Quanta Computer. It appears the HP L2105tm monitor has the same touchscreen and HP does provide support for this model for Win XP and even for Win 2k. Go to HP and get the drivers for the L2105tm monitor. Those work' for the Acer as well.
