Unplayable on High Resolution Monitors

There have been so many threads made complaining about this and Riot isn't doing anything. On high resolution monitors everything is too small. Even if you make the hud, chat, and map as big as possible they are still too small. The mouse is too small which makes the game basically unplayable. Higher resolution monitors are more and more popular and league is unplayable on them. Why even have a 4k resolution option in league if you can't even play the game on it. I had an old laptop that broke so I managed to save up for this insanely good computer and I can't even play my favorite game with it? This problem shouldn't even exist it should've been fixed a long time ago considering how long league has been around. Until Riot fixes this I'm done.
