It's in the README.

Thanks for the reply but if you're referring to changing to Full Screen and back via alt - enter, that's not what I mean. The problem is that in full screen mode, the actual game window is centered on the black screen but is only one-third of the screen's actual physical size. And as far as this line goes, "windowresolution -- Scale the window to this size IF the output device supports hardware scaling." I tried doing that but nothing happened. Is there anything else I can edit in the config file to scale up the "game screen"?

Check the readme and dosbox.conf for the scalers.

Will try to be kind 😁

Normally ALT-ENTER or fullscreen=true should stretch the video all the way and fill your monitor, but it depends on both the graphics driver you have installed, and the output-method used by DOSBox.

First step should be to undo all your changes to the screen & scaler settings and set them back to their defaults.

Next change the output=..... in your dosbox.conf. Try them all and see if one of of will correctly scale the graphics in fullscreen mode.

windowresolution=......... only affects the window size when running in windowed (non-fullscreen mode), but that too is dependent on the driver and the output-method.

You can also try to set fullscreenresolution to either 0x0 (which should pick up the actual resolution from your PC), or fullscreenresolution=1280x768.

If none of this works, try to update your graphics driver.

Thanks much for your help, guys and I was able to get it partially working.
For instance, here are my edited lines in the DosBox config file:

[SD1]

fullscreen=true
fulldouble=true
fullresolution=1280x768
windowresolution=1280x768
output=surface
autolock=true
sensitivity=100
waitonerror=true
priority=higher,normal
mapperfile=mapper.txt
usescancodes=true

[render]

frameskip=0
aspect=true
scaler=normal2x forced

What happens with this config is that the horizontal is right on the money from side to side, but about 25 percent of the vertical is cut off at the bottom of the screen. Any ideas how I can fix that?

Change output=surface to something else.

Thanks again for the replies. I wouldn't blame anyone if they were getting tired of this thread and I wouldn't be offended if they just dropprd it but as for myself it's now become a mission. 😈 . But I digress.

Okay, I tried all the other output options and 'overlay' just gave me a blank screen and the other options an installation error message -- "Supported Video card not detected -installation aborted - Vesa480.dll."

Now "Vesa480.dll" happens to be in the Drv. Folder of my game, so if that's what holding up the parade, how can I get DosBox to recognize it?

IIRC most notebooks won't display low resolutions (those lower than its native resolution) full-screen, unless you turn on 'scretch' in the BIOS.

Here's an experiment; go to Display Properties, and set your resolution to, say, 640x480. Does it displayed full screen? If not, then you should turn on 'scretch' in the BIOS.

Thanks to you guys -- MISSION ACCOMPLISHED! 😁

And Kreshna, you inadvertantly pointed the way by your suggestion of changing the display settings, since that made me fiddle around with the scaler settings. To make a long story short, in the end, I didn't have to change the dispay settings but I simply picked "scan3x" and got rid of the "forced" option. This made the game display take up almost the whole screen!

😏 Uh, and so can I now upgrade myself to semi-newbie and semi-computer dummy?

Thanks again!

Wait, so did you actually turn on the 'scretch' option from BIOS menu?
