This video and the next one might help...

But you can also scale through the video card.

The best pillarboxing for 320x200 graphics is to have fullresolution=1600x1200, use output=direct3d (you need Yhkwong's SVN build), aspect=false and scalers=none.

The best stretching for 320x200 graphics is to have fullresolution=1920x1200, use output=openglnb, aspect=false and scalers=none.

I just use output=direct3d, fullresolution=desktop, aspect=true, scaler=normal2x, pixelshader=crt.d3d.br.fx....

Ok, thanks all. I've read through the posts and watched Mau1wurf's videos. Basically, I've got the pillar boxing covered now, but what if I wanted to run, say, Space Quest 6 stretched (non-aspect scaled) to fit the whole screen? I can achieve this by outputting a 4:3 resolution via DOSBox (1600x1200 on my 1920x1200 screen) and let either the video card or the monitor do the stretching, but both result in slightly softer edges. I still have not figured out how to let DOSBox do the scaling internally like it does with low resolutions like 320x200 output at 1920x1200. Or is this where I need output=direct3d and a patched DOSBox build?

Remember that SQ6 is a VESA game (640x480). It does not even ship with a VGA driver. Aspect correction will have no effect.

Ah, thanks! That was indeed the bit of information I was missing; did not know non-aspect scaling only works for VGA.

Not just VGA. Aspect correction will force the aspect to 4:3. There are others that do not have 640x480 native resolution, like EGA.
