Do you have a log from when you have the ext. display connected so that I can compare them?
Are you kidding me? Just because you can't set your preferences right, you're going to raise a ticket!?! Of course not, you're going to end up like the boy who cried wolf if you do that...macjacke wrote:I didn't get a notification mail for this message = another support case ?
No, I don't want to create the log like this. I don't want one log, I want two logs.macjacke wrote:I would create the log file like this: Start the machine in 2560x1440 mode (external monitor), switch to 5K (internal monitor), shut down the machine. Is that enough?

One log is where you're running just with the iMac alone. As I said, not full screen, but windowed mode. And not 2560x1440, because that's your HiDPI one: (2560x1440) x2 = 5120x2880.

And so is the 3D acceleration. Shutdown the VM and enable them in the VM settings » Display. You'll also notice that the max VRAM will jump from a max value of 128 to 256 MB after that; max the VRAM as well. Then re-install the Guest Additions (GAs) in the guest.00:00:02.109737 GUI: 2D video acceleration is disabled
And don't use it full screen, use it in a windowed-mode. 5K is a *lot* of pixels to move around on a fake GPU. Especially if 2D/3D acceleration is disabled.00:00:01.539126 GUI: UIMachineLogicFullscreen::sltHandleNativeFullscreenWillEnter: Machine-window #0 will enter native fullscreen
