You really need to be more specific in what you are asking. Are you speaking of real time streaming or transmitting previously recorded footage. There is a big difference and many variables in between.
There is no good way to get high quality video from a phone or tablet to a TV. The video recorded to either is a low res proxy image recorded at 720 or at best 1080 horizontal pixels of image. A 4K tv requires at least 200% more pixels for a good image. Most drones can shoot 4K video, but it is only recorded to the SD card in the drone.
High quality can only be obtained by using this file.
Transfer video file from SD card to thumb drive, via PC. Assuming your TV has a USB port, plug in thumb drive and watch via its media player. ( might have to first format your thumb drive to what your TV needs. ) Easy Pesy
