Dell 52340T multi-touch monitor has lost touch capability.
I have a Dell 52340T 23-inch touch screen monitor. I have it connected to two AVADirect Shuttle XPC computers running Windows 8.1. professional. The older of the two computers is connected to the monitor by DVI (computer) to HDMI (using a DVI to HDMI converter). Until today, the touch screen worked fine. Now it no longer responds to touch. The new AVADirect computer is connected by a Display Port cable. There is no touch capability.
The drivers are up to date.
I tried Dell support and HAD THE WORST EXPERIENCE I HAVE EVER HAD WITH TECH SUPPORT!!! I just had to add that, and this is not the first time I've had a bad experience with Dell.
