Your multiple monitor set up has worked well and suddenly it’s not. Here’s a few actions you can take that should help get it going again:
- Check connection – Check that the cables are connected properly at both ends. Try disconnecting waiting 30 seconds and then reconnecting.
- Check for faulty cables or ports – Try connecting the cable via a different port on your computer. If possible, try using a different cable to connect the monitor to your device.
- Reboot your device – To restart your device, select the Start button, then select the Power button and Restart. If that doesn’t work, select the Start button, then select the Power button and Shut Down. Then, turn your device back on.
