I've tried to searching for info on this, but I'm still very confused. 😢

So if I wanna play a game in DOSBox in fullscreen, I'd be best off keeping the resolution of a 640x480 game at its "original" resolution, right? That is... if I want the game to fill up as much of my monitor as possible?

How do I get it to keep the aspect ratio? I have a widescreen monitor and even with "aspect=true" set, it seems to stretch and fill the entirety of the width of my monitor.

Check if your LCD or video card has the option to enable\disable stretch.

Doing a bit more searching, someone recommends that if you have an LCD/Widescreen monitor to set your output to "ddraw" as well?

I was just running "overlay" as I figured it'd allow me to use the scalers to adjust the quality of my image...

Would that possibly make the difference?

In other words, I should:

set output to ddraw
set resolution to 1920x1080
make sure aspect=true

I'm looking to fill up the height of my monitor without distorting the aspect ratio.

Sorry, what should I check for?

If you have an NVidia video card and a monitor plugged into the DVI port, the relevant options are in the NVidia control panel.

There's nothing in that panel you want to touch to fix this

Try an output that's not surface or overlay (Direct3D or DDraw may be good ones for ATI)

then you'll be able to aspect correct away

I know exactly what you're after!

Check your config file and set these settings:

[sdl]
fullscreen=true
fullresolution=0x0 (0x0 means it will use the native resolution of your LCD like 1920 x 1080)
output=openglnb

[render]
aspect=true
scaler=normal3x
