Is anyone having this problem? I can't make DOSBox switch to fullscreen properly in Windows Vista. When I do so, the game screen stays in the original window size and the rest of the screen is black.

Any advices?

Thanks in advance!

I think it would be a good idea if you also posted info about your graphics card, version of your graphics driver, etc. As Qbix says, it works for some. So maybe it is related to some interaction between the Vista graphics driver and DOSBox.

I have a Radeon X800 video card with the latest Catalyst drivers for Vista installed, and I'm using DOSBox 0.65.

Here's how the game looks in fullscreen mode. As you can see it covers only 1/4 of the monitor screen.

latest Catalyst drivers

Really Embry!!! If you want assistance, you should provide us with the version numbers. I have an NVIDIA card and WinXP, and I don't fancy having to spend time looking up the version of the latest ATI Catalyst driver for Vista.

thank you for the information.
None of us has vista. The screenshot looks a bit odd. Just as vista has locked the resolution of the screen. Could you test if fiddling with the parameter
fullresolution does anything for you (for example try regular screen resolutions like 1024x768)
You can find this option inside dosbox.conf (see the dosbox menu entry)

you may need to combine this with the output=surface setting
(setting it to overlay or ddraw for example)

I'm just curious if there is a combination that produces better results.

Hey thanks to you all! Looks like the culprit was the render method=surface + fullscreen resolution=original! It's still not 100% perfect because sometimes when I switch to fullscreen the monitor goes black then returns to window mode again, but in the second or third try it works!

Thanks again!

I noticed something strange in my D3D patch with my 9800 (and now x1900 card). The card lists 320x200 as a supported resolution, but will switch to 640x400 instead when 320x200 is requested. This probably affects only direct3d, but since vista has no more directdraw...I fixed it by silently multiplying everything <512 by 2 and using a hardware stretch (shouldn't look any different then original res I think)
More ATi driver weirdness...anyone care to submit a bug report? 😉
