A:AnswerIf you don't have a couple of extra hdmi cables, check with a friend or coworker to borrow a couple and see if that clears the issue (which would indicate new cables are needed due to a potential short in the cable or cables).

The Acer - 23" IPS LED HD Touch-Screen Monitor has 2 HDMI and 1 VGA. You can have 3 devices hooked up at the same time and switch inputs via the side buttons.
However, there is only ONE usb output for touch and it is always active if plugged in.
There is also no PIP function.
A:AnswerMake sure all the cable connections are fully engaged (you may have to unplug/replug)
If that doesn't work, try reinstalling the monitor (power down the PC, unplug then replug the connections, power back up.)

It will be compatible with any HDMI output device. So the brand (HP) should not be affected.
The touch screen is a separate (additional cabled USB) feature for the monitor. I have two monitor connected through HDMI and am able to switch inputs to the tower I have connected. The touch screen USB is not plugged in the tower so it does not function but the monitor does show my towers screen.
