If you’ve connected an HDMI device to your TV but it goes undetected, you have probably chosen an incorrect input source. Some users get the error message: “This content can not be played” or “Mode not supported” after connecting the device.
The issue generally arises when you are using a non-HDCP compliant HDMI cable or a broken HDMI port on TV. It prevents the HDMI module on your TV from recognizing the HDMI signals. In addition, wrong output settings on the source and outdated TV firmware can also be the reason behind the problem.
Restart TV and Source Device
Whenever youconnect an HDMI deviceto your TV, it may not always work on the first attempt. you may try restarting the TV as well as the HDMI device to see if it starts working again. In most case, a simple restart will work without hassle.
Further, to narrow down the cause, you may try bringing another HDMI device and connect to your TV. This way you can ensure if that specific device is having an issue or there is a problem with the TV itself.
Choose the Correct Source
Another important thing often overlooked is changing the input source on TV. If you have HDMI device connected, ensure the input source is set to HDMI. Or else, the TV will not detect the device.
Changing the input source is pretty similar in most TVs. Press the Source button on yourTV remoteto switch between sources.

Check the Cables and Ports
Next, you should verify if the HDMI cables are free of any wear and tear. Inspect the cables thoroughly, and if you find any damage, consider replacing it. you may try unplugging and re-plugging the HDMI cables too.
Likewise, consider cleaning the HDMI ports and HDMI jacks in the cable. It can help if any foreign materials have been clogged there. you may use a cotton earbud for cleaning purposes.
Moreover, if your TV has more than one HDMI port, you may swap them. This way, you can verify if the problem exists on only one port or the entire HDMI module of the TV is not working.
Not only that, some of the HDMI cables may not support the output signals from the source device. It may either not support the speed or theresolution of the videosignals. So, we recommend you get a newer HDMI 2.1 cable and use it instead.
