problem.2: Image is not 4K 120 fps. I guess the sound bar can’t do that.
conclusion: so I must choose between image quality or sound quality? Please someone help me at least identify the problems(is it hardware or software, ex. Could a cpu replacement in tv work for the first problem?) and if it’s possible a solution.
Hey! Thank you so much for trusting in our community. This TV is an awesome purchase and I want to make sure you can enjoy it fully. So fear not! When having issues with the eARC format, there are a few things you can check. For example, make sure you are using an eARC-compatible HDMI cable, such as an HEAC or HEC cable.
Disconnect all HDMI devices. To make sure that the setup is configured correctly, it's easiest to start from scratch.
Turn on only the TV and soundbar. Any other HDMI devices can be left alone for now. After the issue is resolved, you can reconnect and turn on any other devices.
Connect the TV and soundbar's ARC ports with an eARC-compatible HDMI cable. After a moment, the TV will autodetect the soundbar. Examples of eARC-compatible cables include an HEAC or HEC cable. Make sure you use a cable you know is functional and in good condition.
Once the soundbar is detected, enable the proper settings on the TV. On the TV, navigate to Sound > Expert Settings, and enable both HDMI eARC Mode and Dolby Atmos compatibility.
Update the firmware on your TV and soundbar. If you're still having issues, make sure you have updated the software on both your TV and your soundbar.
If this does not help I recommend letting a service technician have a look. As we would like to gather additional information and look at this from a case-by-case basis, please provide the full model code and serial number of the device as well as your best contact phone number, name, and email.
