Hey everyone 😎

I want to ask your help in solving really annoying dosbox problem.

When I run some games in dosbox on full screen, the dosbox play the game on full screen, BUT it make the resolution narrower,

I will explain:
I get the game on full screen, But also get 1 strip on the left and one strip on the right, each of them 1 inch width,
so the dosbox actually make the resolution narrower.

I hope you understand what i mean, here is part of my dosbox.conf:
fullscreen=true
fulldouble=false
fullresolution=original
windowresolution=original
output=ddraw
autolock=true
sensitivity=100
waitonerror=true
priority=higher,normal
mapperfile=mapper.txt
usescancodes=true

I can stretch my screen with pressing on the buttons of the screen, but this is not elegant solution, I need to fix it with dosbox.conff

Please help solve this problem...
