Well, excuuuuuse Meee! Guess I'm old school with my 1680x1050 dual LCD screen Well no wonder PlayOnLinux and Wine have a problem with your 4K screens. For the most part they are great for older Direct X 9 games which are mostly older games. Some day I'll have enough money to invest in higher resolution screens, but for now I'm sticking with games that run with what I got. Have you posted on the PlayOnLinux forum?
