Hi, I have a problem with my external monitor. My configuration is: macOS High Sierra 10.13.4 Parallels Desktop 13.3.0 (43321) MacBook Pro 13 inch 2017 (3.1GHz i5). Using Windows 10 with the MacBook monitor everything works perfectly. Instead, using my Samsung LU28E85KRS external monitor connected via USB C to DP, the system becomes very slow. Parallels is currently set up as follows: Configuration Game CPU 2 Core 4GB Ram 1GB video memory. Does anyone know how to solve it?
