If the touchscreen is just showing a black screen, first check you are on the right display mode. On your keyboard press and hold the windows key (bottom left) and then press the letter ‘P’, it should now bring up some options, set it to ‘duplicate’.

If it is saying ‘No Signal’ on the screen, check you are on the correct source on the screen. Then check the correct cable is connected to your PC i.e., HDMI is plugged into your PC as well as being plugged into the bottom of the faceplate on the wall (Make sure cables are plugged in tightly).

If still not working, you can try plugging the HDMI directly from your PC into the Touchscreen (plug into HDMI 1) to see if this works. Please contact support either way as we may need to arrange a support visit.
