Hello all,
I'm having problems forcing the resolution and aspect ration in dosbox for games. I've set the following in the .conf file but it does not seem to respect this. When I load a game its completely out of proportion and no the proper aspect. How can I for this when using a massive 27" monitor?

fullscreen=true
fulldouble=true
fullresolution=1024x768
windowresolution= 1024x768
output= ddraw
aspect=true

Try this:

fullscreen=true
fulldouble=false
fullresolution=0x0
windowresolution= 1024x768
output= ddraw
aspect=true

fullresolution=1024x768

Most probably your monitor stretches 1024x768 to its native wide-screen resolution, which is not what you want most of the time.
You may be able to change that in your gfx driver configuration.

Or you could post your photo to show what the issue is? 😊

I'm kind of having trouble with this as well.

Let's take for instance the game StarGunner.

I have a 1080p 27" monitor, and I launch my games through DBGL. Using just the options it provides I usually end up with a stretched out 16:9 image which fills the entire screen.
What I want to get is a 1080p scaled output image (with scanlines) that pillarboxes to the correct resolution.

The best I've been able to get is an image that doesn't quite scale up all the way. My GPU is set to scale by aspect in Nvidia control panel, and this is the config file dosbox references for the game (I added the fullresolution and aspect lines) scan2x or scan3x will only get it so big. Interestingly I can't start the game in fullscreen either or it just silent crashes to desktop. Seems to have something to do with the Apogee logo screen I think. It'll work fine if you manually switch it past that (or even in the middle of the animation)

So basically I want it to scale as large as possible, while keeping the aspect ratio correct.

I suspect this is what the OP wants too.

Here are my examples. Sorry for the delay. Was down under.

As you can see the command prompt is fine but when the game is loaded it does not respect the screen size.

Looks like the scaler's kicking in. Note that scalers don't work in text mode and >=640 modes unless you add a 'force' to it

Try scaler=none and it should be a card-sized game.

THAT IS if you intend to play dos games in little tiny sizes, if that "command prompt is fine"
