Are you experiencing a Chromecast black screen when casting? Let’s fix this together!
It’s very annoying when you cast something on your TV and the screen suddenly goes black to no avail.
Don’t worry, just come along in this guide to learn how easily you can resolve the black screen issue when Chromecasting, without any technical knowledge or complicated steps.
If your TV screen goes black while casting, simply reboot your TV and Chromecast device for 15 minutes, then reconnect the Chromecast securely.
If the screen goes black again, you should troubleshoot your TV as well as the Chromecast setup connection.
Why Chromecast Screen is Black When Casting? – Reasons!
There are quite a few different reasons for a black Chromecast screen, so let’s explore:
- The Chromecast might be receiving insufficient power.
- The Chromecast and source are not on the same WiFi.
- The TV input source is set up to an incorrect HDMI port.
- The HDMI port or Chromecast connector is loose/faulty.
- You are using an incompatible app for Chromecast on TV.
- The Chromecast may be running on outdated software.
- Your Chromecast dongle is overheating or powering off.
How to Fix Chromecast Black Screen When Casting?
1. Reboot the Chromecast & TV
When the Chromecast or the TV does not receive a sufficient power voltage, the device will not function properly and cause Chromecast issues when casting.
The simplest way to deal with this situation is to simply reboot both of your devices to start fresh.
Follow the following steps to reboot the Chromecast and your TV:
How to Reboot Chromecast?
- On your mobile, open the “Google Home” app.
- Click on your Chromecast under the Media Room.
- Tap on the “Settings” from the upper right corner.
- Click on “More” to access the advanced settings.
- Tap on the “Reboot” to restart your Chromecast.
Alternative: Unplug the Chromecast device, wait for about 2 minutes, and reconnect back!
How to Reboot Any TV?
- Unplug the TV from the power outlet.
- Disconnect all HDMI-connected devices.
- Wait for about 5 minutes for a power cycle.
- Plug the TV back into the power outlet.
Tip: Keeping your device unplugged for longer also helps against overheating!
2. Switch to Another Power Source
As we know, the Chromecast can either be connected to the TV’s USB port to receive power or plug into a power adapter, hence directly to the wall outlet.
However, this allows us to test if the Chromecast will only show a black when connected via an alternative way to receive power.
How do Power the Chromecast using Adapter?
- Get the power adapter and the USB cable of your Chromecast device.
- Tip: You can use any micro USB to USB cable as well as any adapter!
- Plug the micro-USB port of the cable into the port on your Chromecast.
- Plug the other end of the cable (USB port) into the power adapter brick.
- Connect the power adapter to a nearby working power outlet to your TV.
- Wait until the Chromecast is powered on and turns on the light for indication.
That’s it, as soon as the TV connects to the Chromecast, you’ll be able to cast to TV from your casting device.
In case the screen still appears to be pitch black, continue with the next step.
3. Change the TV’s Input Source
If your TV is not set to the HDMI input port to which your Chromecast is connected, you will be able to cast, but you won’t see anything but a black screen.
Don’t worry, all you need to do is double-check your TV input source and make sure it’s set to the correct HDMI port.
Here is how to check the TV HDMI input for Chromecasting:
- Locate the name of the Chromecast HDMI input ports on your TV.
- Locate and press the “Input” or “Source” button from the TV remote.
- Cycle between the different HDMI TV inputs using the arrow keys.
- Select the “HDMI 1” or “HDMI 2” on which Chromecast is plugged.
- Click the “OK” or “Enter” button on your TV remote control to confirm.
Correct Source – Screen is Still Black?
If your TV has multiple HDMI ports, try plugging it into a different one because maybe the previously used Chromecast port is defective.
We recommend plugging the Chromecast into one of the back TV HDMI ports since they are less frequently used, hence more preserved.
4. Optimize the WiFi Connection!
If your TV and Chromecast works but black screen when casting, the problem is most likely with the device’s network connection.
Since unstable or weak Wi-Fi signals can frequently cause casting issues, especially black screen when nothing from the casting is able to load.
- Connect casting and Chromecast devices to the same Wi-Fi.
- Move the Chromecast closer to your router for better coverage.
- Reboot the WiFi router to improve Wi-Fi signal strength.
How to Reboot the WiFi Router?
- Unplug the WiFi router and modem from a socket.
- Disconnect the connected cables from the router.
- Leave the router disconnected for about 5 minutes.
- Reconnect the cables back to the router and modem.
- Plug in the WiFi router and modem back into power.
Once your internet connection is stable and you are sure that all of your devices are connected to the same network, test casting to your TV.
If the black screen is still there, continue reading!
5. Configure the Browser Settings!
The Chromecast dongle updates automatically as long as it’s connected to the internet, but when you’re using the Google Chrome browser, updates might be missing.
There is a chance that the issue is occurring due to software incompatibility, so you need to update your browser.
Here is how to update the TV browser for Chromecast:
- Open the Google Chrome browser.
- Click on the three dots from the top right.
- Locate and tap on Settings from the list.
- Click on the About section to check for updates.
- If any update is available, click on Update to begin.
After a few minutes, your device’s browser will be updated, and you can then try to Chromecast on TV.
Furthermore, ensure that the firmware on your TV or casting device is up to date to avoid compatibility issues for further Chromecast sharing.
If you use the Microsoft Edge browser instead of Chrome to cast, you need to disable hardware acceleration because it frequently causes the casting issue.
- Open the Microsoft Edge browser on your device.
- Tap on the three-dot menu from the top corner.
- Click on “Settings” and then click on “System“.
- Locate the “Graphics Performance Preference”.
- Tap on “Use hardware acceleration when available“.
- Next, restart the Microsoft Edge browser to save.
Info: The screen casting to your Chromecast should no longer be only a black screen!
6. Factory Reset your Chromecast
If you’ve tried everything else and still have a black screen, the next step is factory resetting your Chromecast dongle, which is very simple to do.
Performing a reset on the Chromecast will erase all settings in the Google Home app, so you need to pair your Chromecast from scratch.
Here is how to factory reset the Chromecast device:
- Go to the Google Home app on your mobile.
- Tap on your Chromecast device from the list.
- Press on the Settings gear icon from the top right.
- Press on the three dots from the top corner.
- Tap Factory Reset and then select the Reset option.
Once your Chromecast device resets, then set up it on your TV by following on-screen instructions and try to cast from your casting device.
7. Test Chromecast on a Different TV
In the end, if your Chromecast only shows a black screen when casting, the conclusion method should be tested on a different TV.
In fact, you can use any monitor with an HDMI input to check whether the sharing from your Chromecast works in general.
- If the content is displaying, indicates that the problem is with your previous TV port.
- If the screen is still only black on the new device, the Chromecast device is defective.
If none of the above methods resolve the Chromecast black screen issue, it may be worth reaching out to Google Support for further help.
Feel free to share what you’ve attempted here so you can skip straight to the point.
Whenever Chromecast black screen when casting, reboot the dongle and the TV, change the Chromecast power source, and check the TV HDMI port.
In case the culprit is still unclear, optimize your WiFi connection and factory reset the Chromecast.
