Steam Deck Disconnecting From Monitor Screen - [Fixed in 8 Simple Steps]

Note: Have you tried using a different HDMI/video cable?

1. Inspect Your Video Connections

#️⃣Method 1/8

If your Steam Deck disconnecting from TV or monitor screen, the problem may lie in your video connection. Hence, ensuring all components, including cables, adapters, and input ports are functioning properly is key to resolving this issue.

We’ll explore simple yet effective steps to identify and fix video connection problems:

✔️Inspect Your HDMI Connection

If you’re using an HDMI connection, whether through the Steam Deck Dock or directly, ensure the cable is securely attached at both ends.

Look for signs of damage, and if possible, test with a different cable. Double-check that the Steam Deck Dock, if in use, is properly seated and the HDMI port is free from debris or wear.

✔️ Inspect USB-C to HDMI Adapter

If you are not using the Steam Deck Dock and instead rely on a USB-C to HDMI adapter, verify that the adapter is functioning correctly. Check the USB-C port on your Steam Deck for debris and ensure the adapter is compatible with your device. Try another adapter if the issue persists.

✔️Check Display Port Connection

For users relying on the Steam Deck Dock’s DisplayPort, confirm that the DisplayPort cable is firmly connected to both the Dock and the monitor. Examine the cable for frays or defects, and attempt a replacement if needed. Be sure your monitor’s DisplayPort is set as the active input.

✔️Check Monitor/Screen Input Port

Lastly, inspect the input port on your monitor, TV, or screen. Ensure it matches the cable type you’re using (HDMI or DisplayPort) and is set as the active input source. Look for any physical damage or looseness in the port that might disrupt the connection.

Testing with another screen can also help identify if the issue is with your monitor!

2. Update the Deck’s Video Drivers

#️⃣Method 2/8

Outdated video drivers can cause display connectivity issues on your Steam Deck. Keeping the graphics driver updated ensures smooth communication between the Steam Deck and external monitors or TVs.

Here’s how to update the video drivers quickly and efficiently:

Switch the Deck to “Desktop Mode”.
Open the Discover Software Center.
Next, navigate to the Updates section.
Then, look for graphics driver updates.
Select and install the available updates.
Restart your Steam Deck when ready.

Updating the graphics driver often resolves many screen-related disconnections. If the problem persists after updating, consider exploring other solutions in this guide.

3. Select the Correct Video Source

#️⃣Method 3/8

Incorrect video source settings on your TV or monitor can lead to issues like the Steam Deck disconnecting from the monitor. Ensuring the correct source is selected is crucial to establish a stable connection between your Deck and the display.

Here’s how you can confirm and switch to the proper source:

✅Identify the active input label: Check the source label displayed on your TV or monitor to determine which port is in use.

✅Use your TV’s remote control: Press the “Input” or “Source” button to cycle through HDMI ports and find the one connected to your Steam Deck.

✅Match the HDMI port (1, 2 or 3): Ensure the input selected on your display corresponds to the HDMI or DisplayPort where the HDMI is connected.

✅Double-check the input source: Some devices might have multiple HDMI inputs; make sure you’ve selected the exact port your Deck is connected to.

👉Try a Different Input Port

If the issue persists, the problem could stem from the specific input port you’re using. Switching to a different port can help identify and resolve potential port-related issues. So, if you’re using a dock, try switching from HDMI to DisplayPort or vice versa.

Additionally, if you use HDMI, attempt connecting to another HDMI input port on the TV/monitor to rule out a defective port. If you’re using a DisplayPort on the dock, consider switching to another DisplayPort input on your TV, monitor or screen.

Note: Testing various input ports can help determine whether the issue lies with the port or not.

4. Verify Your Docking Station Link

#️⃣Method 4/8

Note: Skip this step if you’re using a USB-C to HDMI adapter and no docking station!

When your Steam Deck disconnecting from the screen, it’s crucial to ensure that the Docking Station is properly seated and securely connected to the Deck. If the connection between the Dock and the Steam Deck is loose, it can cause the video transmission to disconnect as well.

Carefully inspect the Dock’s power cable to ensure it’s firmly plugged in, and check that all video cables, such as HDMI or DisplayPort, are securely attached.

5. Adjust the Deck's Display Settings

#️⃣Method 5/8

So, if your Steam Deck is disconnecting from TV or monitor, it may be due to a mismatch between the Steam Deck’s display settings and your TV’s resolution. It’s important to adjust the Steam Deck’s display settings to ensure compatibility with your monitor or TV.

To adjust the settings, follow these steps:

Open Steam Deck’s “Settings” menu.
Navigate and select the “Display” tab.
Open the menu under the “Resolution“.
Select the same resolution as your TV.
Adjust the refresh rate to match as well.
Apply the settings and test your output.

By making these adjustments, the Steam Deck should maintain a stable connection with your TV. If the display settings are incompatible, your Steam Deck may struggle to maintain a proper connection with the monitor, causing disconnects.

Note: If your Steam Deck won’t show on TV entirely, there might be defective cable or nonfunctional input port, so you may need a replacement.

6. Enable External Display Safe Mode

#️⃣Method 6/8

If your Steam Deck disconnecting from the monitor or TV, enabling the External Display Safe Mode might help. This feature can force the Deck to use lower resolution settings, preventing any display issues that may occur due to resolution conflicts with your monitor, TV or screen.

To enable External Display Safe Mode, head to Settings → Display → Enable External Display Safe Mode.

So, enabling this mode can help resolve any disconnects by lowering the video output to a safe resolution, ensuring compatibility with your monitor.

Note: Also toggle on the “Allow external display refresh control”.

7. Test Via Different Output Monitor/s

#️⃣Method 7/8

In case your Steam Deck disconnecting from your monitor after everything you’ve tried, try connecting it to a different display to rule out issues with the current monitor. Testing with a different display can help identify if the problem is with the monitor or the Steam Deck itself.

Here are different output connections you may attempt at home:

TV (HDMI or DisplayPort)
PC Monitor (HDMI or DisplayPort)
Projector (HDMI)
External Laptop Monitor
Gaming Monitor (HDMI or DisplayPort)

Switching to a different monitor can help pinpoint whether the issue is related to the original display or the Steam Deck itself.

8. Switch the Video Connection Type

#️⃣Method 8/8

If the video output monitor continues to disconnect from your Steam Deck, it’s worth exploring alternative connection methods. Sometimes switching to a different video connection type can help resolve compatibility or signal issues.

The Steam Deck offers various ways to output video, depending on the devices and accessories you are using. Below are some options to consider:

👉Dock HDMI Out

If you’re using the official Steam Deck Dock, ensure that the HDMI cable is securely connected from the dock’s HDMI output port to your TV or monitor’s HDMI input. Sometimes, a loose or poorly connected HDMI cable can cause intermittent video issues.

👉UCB-C to HDMI

You can also connect your Steam Deck to a TV or monitor by using a USB-C to HDMI adapter. Plug the adapter into the Steam Deck’s USB-C port and connect it to your TV’s HDMI input. This method may help if the dock is malfunctioning or if you’re trying to avoid using the Deck Dock.

👉Steam Link App

To wirelessly connect your Steam Deck to your TV, use the Steam Link app:

First, download Steam Link on your Smart TV.
Then, connect TV and Deck to the same Wi-Fi.
Sign in to your Steam account (same as Deck).
Select the Steam Deck on Steam Link to begin.
Enter the PIN shown on TV to wirelessly pair it.

After pairing, you can stream your Steam Deck to your TV wirelessly and enjoy your games!

Wrapping Up!

If your Steam Deck is disconnecting from monitor screen, try inspecting the video connections, updating your video drivers, and ensuring the correct video source is selected on both the monitor and the Steam Deck.

Additionally, switching the connection type, verifying the docking station link, and testing with a different monitor or display can help resolve the issue.
