try changing output mode to ddraw.

Another option (the one I used when I had a simular problem,) is to turn on refresh rate overide for your video card. When I had this problem, I eventually found out that DOSBox in full screen was using 60hz, and this caused the top and/or bottom of the image to be chopped off. Yet, screen caps showed everything. It was rather frustrating. I set the full screen overide to 75hz (chose that because it's the same as my desktop,) and now I don't have the problem.

Since your problems seems to be the reverse of mine (the image is squished instead of stretched up/down,) then it sounds like maybe your refresh rate is being set too high. I could be wrong about that, but I think it's worth a try 😀

i have the same problems and still i dont know how to change the output mode. a quick guide or a hint where to look for help would really help alot!!

Open dosbox.conf.
Change output=

hm...i have changed the output but the problem stays the same!!!

Try using scummvm ;P

Out of curiosity are you using an LCD monitor that's native resolution is 1280x1024? If so that's normal. Your monitor's 5:4, most older monitors and most other resolutions are 4:3. So your screen IS a bit taller than the game would be.

I also have this problem with a lot of programs. I have tried various methods including chaning "aspect" "output" "scaler" and "fullresolution" but to no avail. I do not know how to change the refresh rate for my monitor in DOSBOX as I could not find anything on that in DOSBOX.CONF

Also note that I have an old 4:3 aspect monitor, not an LCD.

Thanks in advance.

Uhm not dosbox is responsible for the refresh rates, but your OS/drivers.
Think with that dxdiag tool or something you can change it.
