However, if we go from a scale factor of 100% to 125%, we get a screen with proper content, but with a high resolution (higher than the display) from the point of view of the guest, scaled down to fit the display.

When we now select fullscreen in the frontend we only get some scrambled rectangles on the screen. Now we connect the external monitor and choose to use only that monitor. The switch between these two states goes through Windows display settings:Īssume that we have everything working as expected on the laptop display, with native resolution in the Virtualbox frontend. It seems like there are two states: I either get native resolution on the laptop monitor or the external monitor. The behavior I get is somewhat complicated. The behavior I expect from the frontend is that I always get native resolution when I select a scale factor of 100% in the View menu. Connected to this, I have an external monitor with a 2560x1440 resolution. My setup is a laptop with a 2736x1824 screen.


This ticket concerns how to get native resolution in the Virtualbox graphical frontend when running under a Windows 10 host.īy "native resolution", I mean a 1-1 mapping between pixels on the display and pixels in the frontend fullscreen window.
