Testing new 4k monitor & need video suggestions.

[state_of_arousal]

I just got a 4k monitor and I want to test it with the highest quality video I can find.

I don't care about video length, as long as the video is 4k and the highest quality you know of then I will check it out.

Searching the video forum for "4k" doesn't work because the word is too short for the search parameters.

So please link to the highest quality videos you know of for my testing purposes - torrent preferred, but MEGA would be okay too. Not interested in streaming video sites.
