Huge Scaling Text on 4k Monitor.

Recently I got a 4k monitor and when I tried playing league last night all the text on the screen (like q, w, e on abilities, summoner names etc.) was massive in game causing me to barely be able to see what I was doing. After doing some research I found out that this was caused by the window scaling used by 4k displays. But after turning that down to normal my mouse was so small I could barely see it. I couldn't find any other solutions to this problem.

Is Riot planning on releasing any 4k support any time soon? It's been like 6 months since the HUD update and it doesn't seem like something that should be that hard.
