If you see an error on your iPhone, iPad, or iPod touch that says
Cannot Play Video - The connected display is not supported
It typically points to an attempt to output video through a non-supported video output method. Follow the troubleshooting steps for your viewing method below to resolve the issue.
If you are attempting to output video from your iPhone, iPad, or iPod touch, you are likely using an unsupported video output configuration. Some examples of unsupported video output configurations include:
Using a 30-pin dock connector to VGA adapter.
Any non-HDCP (High-bandwidth Digital Content Protection) compliant display.
To resolve this issue, switch to a supported video output adapter. More information on supported Apple A/V adapters can be found on Apple's support site.
If you are not currently using a video output method or Airplay mirroring, restart your device to get back to streaming.
Press and hold the side button and one of the volume buttons at the same time until the sliders appear. Drag the top slider to turn your device completely off.
If the sliders don't appear, press and hold the Sleep/Wake button until the red slider appears, then drag the slider.
After 10 seconds, press the Sleep/Wake button.
Once your device powers on, try Netflix again.
