P2418HT, multiple, unable to give input simultaneously

Question

I have multiple monitors connected to my pc. I can get visual feedback from windows showing that multitouch DOES work on multiple monitors at the SAME time. (example: I can put 4 fingers on one screen and 4 on another and drag them around the desktop and watch the feedback that windows automatically gives) But the issue is that the monitors that aren't the first monitor I initially touched, do NOT send an actual input. I can open two instances of Paint on different monitors and try writing on them both with only 1 working. I can open one instance of Paint and extend it across displays and still only one monitor will send input (even though I can clearly see the visual touch feedback). So how do I get windows to send actual input through those other monitors?

After talking with Dell support, their is no current native solution. Best bet is to do a IR touchscreen overlay.

We tried reaching you on a private message asking for the private P2418HT Service Tag numbers to ascertain the warranty but did not receive a response. Please reply to the private message whenever you are available.

In reading the statements on page 9 and page 52 in the online P2418HT User's Guide =

Connect the USB cable that comes with your monitor to the computer. Once this cable is connected, you can use the USB downstream connectors on the monitor and the touch screen function on the monitor.

Use the Dell provided USB cable to connect your computer.

It sounds like both P2418HT would need their USB 3.0 upstream cables connected to the PC. Do you have both P2418HT USB 3.0 upstream cables connected to the PC?

Hi - was there any update to this? I have two of these monitors, and I find that monitor#1 works perfectly fine with touch - though when I try to touch monitor #2, the "mouse" is on monitor #1. I swipe up to scroll on monitor #2, and the window on monitor #1 scrolls.

Is this what you found?

I had this same problem and spent ages trying to resolve it, putting this here in case it helps anybody else. You need to:

Open the Windows Control Panel
Choose Tablet PC Settings
Under Configure, choose Setup
Follow the prompts on each screen to identify it as a touch screen

The touches then work on the correct screen rather than the one set as the main display.

thank you! I thought I had wasted $$$ on a second touchscreen monitor. Both working great now!
