Hmm, what kind of a GPU does your netbook have?

Intel Graphics Media Accelerator HD

I remember having this once on my Acer netbook. But I don't remember what I did to resolve the issue.

Is it a first generation netbook with GMA 945 graphics?

In dosbox conf try different output. In the startmenu dosbox folder is an edit config entry or so

it is a pretty high-end netbook (aspire 1830T) and I have already tried to choose non-default output resolutions but with no result 🙁

Not output resolutions but the output option in dosbox config (surface, overlay, ddraw, opengl)

Also, look for updated graphics card drivers on the Acer website. If you didn't update the drivers yourself, chances are you're using either the default Windows 7 driver which only supports minimal functionality, or an outdated version. If you want to use ddraw output (or direct3d when using a custom DOSBox build which supports this method) you should also run the latest DirectX 9 installer available from Microsofts website *.

* Some people say this is necessary, some say it isn't because the DirectX version included in Windows 7 is backwards compatible. I've had actual cases though where games or emulators wouldn't run properly or at all without installing the DX9 components. In any case, running the installer won't harm your system in any way.

You can search directly on Intel website (just make note of the exact name of your integrated card). Or use an application like drivermax, to keep your drivers updated. note: Had really BAD experiences with intel video cards, always a lot of problems and incompatibilities...

I can second that, high-end and Intel graphics chip are never in a non-controversial sentence.

installed all the updates and played with the output options; surface works now 😀.
Thanks all for helping!^^

glad to help 😉
