Problem seems to be the DisplayPort to VGA adapter that does not work well with Windows 10. We're now shopping for adapters that do work...
Hey guys, Have the following issue: we bought 16 Dell Optiplex 3070 + Planar Touchscreens PT1745R with our POS system for our stores. We use Windows 10 Pro. When we connect the Planar to the computer (via USB cable and display port to VGA adapter cable), all other input devices (keyboard and Zebra hand scanner) stop working. It looks like the Planar touchscreen monopolizes all input. We did a reset and started out with a regular monitor; everything was working fine. When we swapped the regular monitor for the Planar, keyboard and scanner no longer work... Is this something that can be solved by changing the settings in Windows?
