Customize Virtual Desktop size with fullscreen?

Post by kebabbert »

I have Solaris 11 Express as host. WinXP SP3 as a guest. I am using Nvidia GTx560 Ti, thus I am able to use a virtual desktop of 3840 x 1080 on my 24" monitor which has 1920x1080 resolution.


When I switch WinXP guest to full screen I get a 1920 x 1080 window in the middle of the screen, with black borders around. This is good because when playing VLC movies full screen, the VLC window is exactly 1080p and cover exactly the WinXP guest.


Then I installed 3D acceleration in WinXP in "safe mode", and increased video memory from 16MB to 128MB. Now, when I switch WinXP guest to full screen, the WinXP guest is now 3840 x 1080 which is not good. Because, when I start a movie in 1080p in Windows, the movie VLC window becomes stretched to cover the entire 3840 x 1080 screen. This makes the movie to lag a lot. If I makes the movie VLC screen smaller, to 1080p, then there are minor issues: it still lags etc. The main problem is that I can not play full HD movies without lag. I tried to enable 2D accelartion, but I can not see any 2D checkbox.


Can I resize the full screen WinXP guest window to cover exactly 1920 x 1080p, even though I have 3840 x 1080 host screen? Can I customize behavior?

Open the display settings in your XP VM and choose 1920x1080, and of course you might want to turn off auto-resizing of the VM so the resolution will stick.
