  I don’t think that’s the case; it handles the image from a 4K capable device fine but doesn’t from a supershitty android box. it’s an electrical issue, somethings busted in there, that’s why I’m in this community.

    Just tell us the model of the TV and the devices that work, and the devices that don’t.

    If you want an answer to your question of whether this happens to old devices, yes, it does. And the way that it usually happens is that the old device doesn’t understand newer signal protocol versions.

    That would explain why some devices work perfectly and some devices don’t work at all, because an all or nothing situation suggests something going wrong with a handshake or other signal negotiation protocol.

    Some devices fall back to earlier versions, and some don’t. Some only fall back if instructed to, so even if it does support an old version it expects to be told.

    Another point of failure could be the cable itself, where it won’t pass certain types of signals correctly and might screw up the handshake. Have you tried other cables?
