I've recently been having this problem on a macOS 10.13.2 virtual machine where I go into the full-screen mode and, instead of changing the resolution to 1440x900 like it should, it automatically switches to the 720x450 HiDPI option, where nothing seems to fit on the screen. I've tried changing the screen resolution manually via the Displays panel in System Preferences, but it switches itself back to HiDPI every time, and it's been extremely frustrating. However, when I go into the maximised windowed mode, it automatically switches to a more comfortable 1440x803 resolution. However, I plan to use this machine in full screen. I've searched everywhere and nothing I've tried has worked. I am using Workstation Player 12.5.8.
If anyone could help me on this, that would be great.
Hope you can help,
