With the existing UI, if you play at 4k resolution, the healthbars of enemies and several other things become so small that they are difficult to see, especially if you are (like myself) colorblind. When designing the new UI, please take this into account.
I submitted this problem to customer service but they told me to come to forums and announce it instead. The mouse cursor is a huge problem as it shrinks to an icon tinier than a minion's head. It makes the game unplayable so I currently have to downgrade my graphical settings to play instead of in gorgeous 4k.

I made this thread when I first got my laptop (running 4k) with the hope that it would attract more attention from the community members with the same issues. If we can get more attention from the community (by creating a mega thread) it would hopefully accelerate the process of Riot offering 4k support.
