I think it wood be good if there was a fullscreen stretch to fit option, so you could put it in a high resolution but still have the picture take up the whole screen.
Why would you want to do that? So you don't get those nasty horizontal lines that you get at low resolutions on big monitors.

I tried it and I got a black screen with a garbled monitor error message at lower resolutions. 🙁
Any idea why that might be happening?

If you can compile dosbox yourself, do this:
change in sdlmain.cpp following lines:

1if (sdl.desktop.fullscreen) {
2    if (sdl.desktop.fixed) {
3        double ratio_w=(double)sdl.desktop.width/(width*scalex);
4        double ratio_h=(double)sdl.desktop.height/(height*scaley);
5        if ( ratio_w < ratio_h) {
6            sdl.clip.w=(Bit16u)sdl.desktop.width;
7            sdl.clip.h=(Bit16u)(height*scaley*ratio_w);
8        } else {
9            sdl.clip.w=(Bit16u)(width*scalex*ratio_h);
10            sdl.clip.h=(Bit16u)sdl.desktop.height;
11        }

1if (sdl.desktop.fullscreen) {
2    if (sdl.desktop.fixed) {
3        double ratio_w=(double)sdl.desktop.width/(width*scalex);
4        double ratio_h=(double)sdl.desktop.height/(height*scaley);
5        sdl.clip.w=(Bit16u)sdl.desktop.width;
6        sdl.clip.h=(Bit16u)sdl.desktop.height;

There are two occurences of this.
Now change your dosbox.conf:

1fullfixed=true
2fullwidth=whatever you want
3fullheight=whatever you want
4output=anything but surface

Now there's no more cinemascope;-)
