Fixing Steam Deck or Steam Deck Dock not Connecting to Monitor

How to Fix Steam Deck not Connecting to Monitor

The Steam Deck includes a USB C port which allows for connection to a monitor. To accomplish this, you will need a USB-C hub or dock with an HDMI port and an HDMI cable. Connect the HDMI cable to both the monitor and the USB C adapter and then connect the adapter to the Steam Deck. This will display the Steam Deck’s content on the monitor. However, some people may encounter difficulties with this setup. In such cases, troubleshooting steps can be taken to resolve the issue.

Here’s how to fix Steam Deck dock or Docking Station not connecting to external display.

Fix #1 Restart Steam Deck

A common solution for resolving software issues with electronic devices is to restart them. The Steam Deck is no exception to this. You can restart the device by holding the power button for 10 seconds or by navigating to Steam > Power > Restart through the device’s menu. After the restart, attempt to use the monitor with the Steam Deck again. If the issue persists, consider trying the troubleshooting steps below.

Fix #2 Firmware Update

If your Steam Deck is not connecting to an external display, one potential solution is to update the device’s firmware. An outdated firmware version may be causing the issue. To address this, try updating Steam OS to the most recent version available. This may resolve the problem.

Updating Steam Deck

Step 1: On your Steam Deck, press the Steam Button.

Step 2: Go to Settings.

Step 3: Go to System.

Step 4: Check for any Software Update.

Step 5: Restart Steam Deck.

Fix #3 Check HDMI Cable

Another potential solution is to check the connection between the Steam Deck and the HDMI monitor. Ensure that the HDMI cables are securely plugged in and functioning properly. Try using a different HDMI cable if you have one, as a malfunctioning cable could be causing the issue. Additionally, make sure you are using the correct HDMI port on your monitor, especially if there are multiple ports available.

Fix #4 Check Dock or HDMI Adapter

It’s possible that the problem with your external display is caused by an issue with your dock or HDMI adapter. If the external monitor works when the device is not docked, but not when it is, it’s likely that the dock is defective. Try checking if the dock is causing the issue.

  1. Connect an HDMI cable from the dock to the monitor or TV.
  2. Connect the USB-C charger to a power source and to the dock’s rear USB-C port. Use the charger that came with your Steam Deck, unless the manufacturer states otherwise.
  3. Place the Steam Deck on the dock and connect the USB-C dongle to the port on the top of the Steam Deck.
  4. Switch the input on your monitor and wait for about 10 seconds for it to detect the signal.
