Second monitor or dock not working? Try this first

Most monitor and dock problems come down to a loose cable, the wrong input or Windows not detecting the screen.

Try these, in order

1. Check the cables and power. Make sure the monitor is on and both ends of each cable are pushed in. Check the dock's power light.
2. Check the input. Use the monitor's buttons to pick the right input: HDMI, DisplayPort or USB-C.
3. Ask Windows to find it. Press Windows + P and choose Extend. Or go to Settings > System > Display and select Detect under Multiple displays.
4. Reconnect the dock. Unplug your laptop from the dock, wait 10 seconds and plug it back in.
5. Restart with the dock connected.

Screens in the wrong order?

In Settings > System > Display, drag the screens to match how they sit on your desk, then select Apply.

Still nothing? Email support@deepnet.com with the make of your dock and monitors, or a photo of how they're connected.
