I think I've read just about every post on the dual monitor frequently changing resolution issue. I've worked on this for hours and am thinking about giving up and demanding a refund. A description of my issue: I have a dual monitor setup. I'd like to use Windows full-screen on both monitors, keeping a resolution of 2560 x 1600 on BOTH monitors. I've gone to Control Center --> Preferences --> and selected to use my virtual machine in full screen mode The dual monitor setup works great. However, when I un-plug from my second monitor and plug back in, the screen resolution gets screwed up and displays in 800 x 600. It will never remember the screen resolution that I specified (2560 x 1600). When I look at other threads on this issue, everyone recommends that I de-select full screen mode. I do this, but now I can't extend my display across the two monitors. HELP! I am beyond annoyed!
Hello, is the second display also highDPI? Have you tried in VM config (http://kb.parallels.com/en/117287 ) go to Options > Full screen > Scale to fit screen set to "Keep ratio" (http://kb.parallels.com/en/116141 )?
