I have 1 1080p monitor, a 4k monitor, and a 4k tv using the DF taskbar. The 1080 is sharp and everything is scaled properly. The 4k ones have a bluriness about them, and when I click the little arrow for the background apps, it is extremely tiny. I notice it opens on my main monitor (the 1080) first and quickly transfers to the other one. I don't want to switch my main display either. Also, when I minimize things on my tv, they shift to my second monitor. So when I reopen them they open on the monitor, not the tv. Very annoying.
