Can you press ALT+Enter to enter fullscreen and does it work?

If it does work then when you are starting DOSBox it's likely not reading the config file you changed.

Hi,
Yes ALT+Enter switch to Fullscreen Mode correctly.
But I am sure, that the conf-file is loaded, because I added "autoexec" commands, which are processed successfully.
Thanks for your help

1. Go to the DOSBox directory from the command prompt
2. Run "set SDL_VIDEODRIVER=windib"
3. Launch DOSBox using your conf fle

If that works then you need to add SDL_VIDEODRIVER=windib to your environment variable. The reason you need to add it is due to the video card driver.

I tried that, but it doesn't help. Thank you nevertheless.
The only thing that "works" if I use DDRAW as Output an Windowsize=1024x768 (Screenresolution), but the Window is not centered, so it's not useable...
I tried "Fullscreen" inside conf and/or as parameter...

I also tried to switch from "S3_SVGA" to VGAonly... (I use a S3 SuperSavage)

Make sure you are using DOSBox v0.74-3
Are you using a CRT or LCD?
DosBox by default will set the monitor to the resolution that the program requests which for most is 320x. So if DOSBox is using default settings then the screen resolution will change to 320x or if an LCD the closest resolution the monitor can use.

You can set DOSBox to use your desktop resolution by changing fullresolution to 0x0 or desktop but make sure you change Output to a value different than surface because surface doesn't scale, also you might want to use the scalers as well but if the screen is really 1024x768 resolution then I doubt it.

By fullscreen are you confusing fullscreen with "black bars"? If DOSBox is "fullscreen" then you shouldn't see the title bar.

It's a notebook. I user the internal LCD with a resolution (native) of 1024x768. The Dosbox Windows doesn't scale at all, I always see the titlebar. I tried out many different outputs (only Surface and DDRaw works), all other will leave a error message with different resolutions (for window and fullscreen mode) and both modes. It's like he ignores fullscreen=true (and yes, there is no # in front of the row.
