VirtualBox v6 screen resolution

[ondrejsm]

Hi, I use VirtualBox many years on my Mac. But since version 6 is out, I have problem using it. Version 5.x is ok.

I use 2 more monitors with my Mac and when I move Virtualbox screen from one monitor to another, VB is scaling resolution. My Mac has its default 2880x1800, another two monitors have 1920x1080. VB on 1920x1080 is ok, but when I move its window to Mac monitor, it is almost impossible to view what is on screen because everything is quite too small. Is there some solution for this problem? I didn't find anyone complaining about it, but I had this problem in Mojave on old MacBook Pro mid-2014 as on new MacBook Pro 15-inch 2019. External monitors are connected via Apple USB-C Digital AV Multiport Adapter.

Thanks

Try setting scale factor to 200% in the VirtualBox Manager Preferences | Display.

No, scale factor 200% makes it much worse - on FullHD monitor I have to scroll from side to side and on MacBook monitor it is similar...

On this picture, it looks like it should look (FullHD monitor):
