How to Fix Screen Mirroring Netflix No Video
This issue can be both hardware and software related. In this guide, I’ll explain to you every necessary step to solve this problem. So buckle up. We have work to do.
Here are the solutions to fix Screen Mirroring Netflix No Video issue:
1. Check Netflix Support on TV
Make sure the TV you are casting to has multicast support or allows Netflix streaming in general. Some old TV supports Miracast or Screen cast but doesn’t support the Netflix app itself. Those can’t be used to screencast Netflix and will turn a black screen.
To check if your TV‘s Netflix Support-
- Check the pre-existing app on the TV and Find Netflix.
- Check your TV’s app store and Search. If nothing comes up, then it doesn’t support Netflix.
If your TV doesn’t support Netflix, you can buy a Chromecast or an Amazon FireTV dongle and connect it with the TV via HDMI. You’ll be able to watch Netflix without changing your TV.
2. Check If Your TV Supports HDCP Code
To stop piracy and screen recording, Netflix developers add a new codec system to their platform, HDCP (High Bandwidth Digital Content Protection) codec. If your TV doesn’t support that, Netflix doesn’t allow you to cast content on the TV.
To check if your TV supports HDCP check your TV specification or contact the support of your TV brand.
3. Update TV OS
Sometimes an old version of the smart TV operating system can cause various apps not to work, including Netflix. Casting devices and Chrome Cast dongles also need to keep up to date to run apps properly.
To update your TV’s OS-
- Go to Settings.
- Find Software Updated or Firmware Update.
- Check if there is any update available.
- Select Install Update.
- Restart your TV after the update is completed.
If you are using a Chromecast, that needs to be updated as well.
- Open Home Screen.
- Go to Setting > System > About > System Update.
- Check for any updates. If available, download and install.
- Restart Chromecast.
4. Update Netflix App
Sometimes outdated Netflix apps on your phone, TV or both can cause incompatibility. To fix that, check if Netflix is updated on both your TV and the Casting Device.
To Check Netflix updates on TV and Chromecast-

Make sure your devices are paired up properly. Also, make sure you are logged in to the same Netflix account and the same profile.
6. Make Sure Your Devices Are Under The Same Network
This is a very common mistake. You might try casting your Netflix onto the TV, but the TV isn’t connected properly to the network. On the other hand, maybe the TV is connected properly to the wifi network, but your device is in Data mode.
Unless both casting source and receiver are under the same network, casting won’t work.
7. Check The Region of Your TV and Your Phone/ Tablet
Both the TV and the casting source should be under the same time zone and the same location or region in the setting.
If not, you might be trying to cast something that is not available in the region of the TV.
8. Check TV Connectors
Check the TV connectors such as HDMI cables and Network cables. The faulty cable can cause major issues, such as a black screen while casting.
9. Delete Netflix App Cache Files & Clear Data
