Judging by your link and some quick googling around, including this, it's for mobile displays which have a lot less resolution than a 4K TV display.

That said, the 4.5Gb/s speed of it seems enough to feed a 4K display at 100Hz (I didn't really dig enough into it to determine the protocol overheads or even much detail on protocol so take it with a pinch).

At minimum, you should probably open your TV and see if there is a flat cable with the right number of lines from the display to the controller since if it does not it's highly unlikelly to be that standard (and even if it is but using a non-standard connector, you'll need specs to figure out which pins are which lines in order to build an adaptor).

Mind you, it sounds like a fun project if you have a TV around that you don't mind too much if it ends up broken.

Yeah, I think newer panels are probably MIPI DSI but there are cheap controller boards for that too. I don't think I will do this as I really don't have a need.

A previous, now deleted post sent me down this rabbit hole. I also understand why the OP deleted it. There are a lot of professional unboxers here who get upset with the idea of building anything.
