![]() ![]() Such an automatic "zoom-in magnifying," if it may be put that way, while under full-screen mode would continue to feature black bordering, although a much-larger area of the screen would be put to good use. ![]() In other words, the mapping of individual pixels to larger (2x2, 3x3, and so forth) blocks of like-value pixels. ![]() It is to be remembered, though, that the best scaling method is integer-factor scaling. The remaining space is occupied by black borders surrounding said application. Game (or application at hand) remains in a smaller window (at it's running resolution) without scaling up to full screen as it should in these situations. When running games such as starcraft (and very likely any game set to a lower resolution then the screen's potential), virtualbox fails to scale the image up to fullscreen in full screen mode. Then, the only case where VirtualBox might offer to scale the display is when the user runs a full-screen guest within a VirtualBox window.ĭisclaimer: I know next to nothing about Direct3D. For instance, I have my driver set to respect 4:3 aspect ratios on a widescreen display, while others might prefer to stretch. The host's display driver is better at that, anyway. This would postpone the need to implement scaling in VirtualBox proper. Would it be possible to simply allow the guest to change the host's desktop resolution via !DirectX/Direct3D? Specifically, when the guest invokes (say) IDirect3D9::CreateDevice() with D3DPRESENT_PARAMETERS.Windowed = false and BackBuffer = foo, could this be passed through to the host? Effectively, VirtualBox itself would behave like a full-screen Direct3D game, temporarily switching the display resolution (without mucking up the host desktop). Searching around Google turns up some discussion about solving this generally, but perhaps a quick fix could provide 90% of the benefit without committing to a fully general solution at this time. ![]()
