Now, you should test and undertake several inputs on your television. Precisely, check if your TV is HDCP compatible.
How to know that your television is HDCP compliant:
- Scan the box of your TV.

- Detect whether there is listed HDCP anywhere in the descriptions of video ports. Let, you don’t find anything like this, that means your TV is not HDCP-compliant.
- Ask the customer service section for the manufacturer of your TV. Tell the model number of your TV to know whether it is HDCP-compliant or not.
Provided that, your television is HDCP-compliant, then you will see the below types of HDCP-compliant connections:
- HDMI (4K@60Hz)
- HDCP 2.2
- ARC
Note: Make sure that your HDMI cord is linked with any of the three connections. That is HDMI (4K@60Hz), HDCP 2.2, or ARC.
Choosing the accurate output given on the television menu.
- In doing so, you can use the TV remote input button to fix the accurate input for your TV.
Note: Different TV manufacturers may come up with different terms for the input button. If you see there is a TV/Video, Input, or Source button, these are also input buttons.
- Get HDMI, HDMI 1 or HDMI 2.
Note: Such that I have no remote for my TV, still I can use the input button.
- What’s more, you might have to use the input button for cycling through the inputs.
While cycling through the inputs, hold 10 seconds on every option as your TV can set a secure connection to the corresponding appliances.
- Reset the TV remote. If your TV has no remote, then you may check this TV remote from Amazon.
- Don’t keep any devices between the digital box and the television which doesn’t support HDCP. (If there is any non-HDCP-compliant device, try a secondary audio system on your television.)
Even, you may try an optical cable to apply with the audio receiver to your television.
Make Sure that your TV includes the Most Recent Firmware
Check out the TV manufacturer’s webpage to know if your television has the latest firmware. This is also an important part of this troubleshooting.
