Hi Lukas, my name is ***** ***** welcome to JustAnswer!
I'm sorry to hear that you're running into this issue. I know that must be frustrating.
You say that the monitor works fine if you connect it to another machine. Are you connecting to the other computer via HDMI or VGA? When you connect it to the ACER do you get anything at all indicating that a new device has been connected?
