Sounds like your monitor doesn't suooport the resolution/refresh rate DosBox is trying to set. I've noticed that XP will sometimes allow modes that the monitor doesn't really support, even when "Hide modes that this monitor cannot display" is checked in the advanced display properties!

Try this:
set fullheight and fullwidth to your current resolution, and set fullfixed to true.

Thanks it almost worked.
I did the things you suggested and I can see the screen now.
But if I start a game, I get a field around dosbox that shows the desktop.
[edit: do NOT POST LINKS TO BITMAPS]

Try setting fullscreen to true.

That didn't work.
With fullscreen true, dosbox don't work at all it just returns to windows.

fullscreen=true
fulldouble=false
fullfixed=true
output=opengl
fullwidth=1152
fullheight=864
hwscale=1.00
autolock=true
sensitivity=100
waitonerror=true

For me, the 'overlay' function allowed me to view a game on my TV in full-TV mode, while still running it in a windows on my TFT screen 😎

I have to say, that the colors and everything looks *so* much better on the TV than on the TFT screen.

I have the same settings and problem as Jackal.
If I chose fullscreen false, my first problem returns.

I think someone has already posted about this. It seems DOSBox kicks you to desktop if OpenGL full-screen is invoked at startup but works properly if started windowed and then switched via ALT-ENTER. Weird.
