I am attempting to get DOSBOX to run with an older DOS based application.
I have got it running, but none of the screen sizes I have been able to use are acceptable.
If I set scaler=none, I get a very small screen. With scaler= hq2x forced, I get a screen that
is too big.
What I think I would like is something halfway in between these two options, e.g. scaling of 1.50.

Below are the relevant parameters I am working with:
-----------------------------------
fullscreen=false
fulldouble=false
fullresolution=1280x1024
#fullresolution=original
windowresolution=800x600
# ^^^ tried lots of things above. None made any difference
output=ddraw
# above parameters from the [sd1] section
# below parameters from the [render] section
aspect=true
scaler=hq2x forced
# This makes it too big. Without the "forced" it does nothing.
#scaler=none
#hwscale=2.0
# No value of hwscale seems to have any effect, with or without the hq2x parameter.
-----------------------------------

Added comment: I have done a large number of searchs and tried lots of suggestions that seemed to work for others, but none of them work for me.
