This was posted on the Mavic Facebook group-    "Yesterday I did my first flight with my Mavic 2 Pro and I did record about 24 mins 4k 30fps on my sd card but cannot see it good on my computer because he is too old but I did notice that 4 parts of the movie was recorded on my cell phone ??? About 4 parts of 3 mins each. I tought that everything would be record on my sd card ?? Next time I will record in 1080p." You get a local cache of the video on your phone that's lower quality than what's on the sd card in the drone. You will find the videos get cut up into 4gb files this is a limitation with the file system on the sd.
Has anyone tried playing your Micro SD card using  a card reader  on your 4K TV or would it be to slow ?  Photos  would ne fine but what about video. I'm thinking H264 would work but not h265

Using something like this -It does come with a USB 3.0 cable

Delete, missed you where actually taking about a TV, not a pc.

I'm not sure I understand your question?

If you record some 4K video with your Mavic Pro 2 and then take the Micro SD card out and put it in to a  USB 3.0 card reader and insert that into your 4K TV USB slot will the video play smoothly ?

I have a Samsung 4k TV and the native file from my Mavic Air in 4k will NOT play on my TV. I don't think its the file size or transfer speed. I think it's just the file type. Maybe if I converted it, it might play. I put a EVGA GeForce GTX 1060 3GB in my desktop to better handle 4k video. A lot of video editing is processed by your GPU, rather than your CPU. I also have 32 GB RAM and a Solid State Hybrid drive. It edits 4k well.

On my samsung 4K TV I cannot directly play the Micro SD card when plugged in the USB. The card is recognized but I cannot open any folder.

The problem is that there are a lot of variables - what card reader, what TV, how was the video recorded, etc.

Hi, Thanks for the inquiry. The files on the mobile device are only cached files, Yes, it's low quality and the real one is on the SD card. I will forward your concern about the SD card and 4K TV to see if that could be done to our R&D engineers

You might want to check what file formats your TV can read, should be in your manual for the TV.

Then what I'd suggest is...

1. have 3 clips - 1080p, 2.5k & 4K in H.264 (.MP4)
2. try a USB stick with the 3 files

hopefully some combination will work

This. Consumer electronics firmware is notorious for being extremely picky about all sorts of variables when it comes down to playback of video. The container type, encoding, bitrate, resolution, and tons of other issues can adversely affect the ability to playback the file. What's worse, is that often the requirements for playback aren't typically well-published by the electronics manufacturer which makes figuring out what "to do" a complete and total guessing game. Have you tried to play back using another container type...like .MOV instead of .MP4 or vice versa?

Seen opposite problem.  The manufacture of recording system being sloppy with their H.264 recording.  To play their recordings you have to convert file or use a binary editor to change some incorrect recording info in header.
