My monitors aren't working or my laptop won't display on them

If your monitors are black, show "No Signal," or aren't detected when you connect your laptop, check the connections and display settings first.

Check the basics

1. Make sure each monitor is turned on (look for a power light).
2. Check that the video cables are firmly connected at both ends, and that the dock's power adapter is plugged in.
3. Use the monitor's buttons to confirm the right input is selected (HDMI, DisplayPort, or USB-C).
4. Unplug the laptop from the dock, wait 10 seconds, and plug it back in.

Check display settings

1. Press Windows key + P and choose Extend.
2. Right-click the desktop > Display settings. Scroll down to Multiple displays and select Detect.
3. To change which screen is on the left or right, drag the numbered boxes at the top of Display settings to match your desk, then select Apply.

Reset the dock

1. Unplug the laptop from the dock.
2. Unplug the dock's power cable, wait 30 seconds, and plug it back in.
3. Plug the laptop back in and restart it while it's docked.

Distorted colors, flickering, or lines

Try a different cable or port if you have one. If the problem stays with one monitor, it may need to be replaced. Submit a ticket.
