Can't get 4K from the Nintendo Switch from the mClassic?

In our recent review of the PhotoFast Gamer 4K Plus I mentioned that the m Classic doesn't output 4K. A number of people messaged me and said that it sure does. upon looking at the product page and the specs, it does indicate that it should output 4K or at least 1440p. through multiple tests, however, on multiple TVs all that I am seeing is 1080p. I even set the output of the switch to 480p and 720p to see if I could get it to upscale correctly, and it does not. does anyone have any suggestions? Was there an update after the initial release?
