Hi!
I did a Dual Monitor Demo in C128 Basic.
This demonstrates the capabilities of a C128 with both video signals
connected to different monitors. It is written in basic and took about
one day writing it on a real C128 (with a sticky space key). Since I'm
not really a professional programmer, so don't expect too much if you
analyze the source code. :-D
The D64-Image if you want to run it in Vice:

The Youtube-Video:

For impatient viewers: The most action starts about 1:35.
I don't know if there was any other dual monitor demo yet, so this might
have been a world premier that has taken place on the Commodre Meeting
in Graz, Austria last Friday! (With beamer and monitor.) ;-)

Oh, a rare C128 demo. Thanks for that!

I think this is on the thread topic. When I programmed on the 128, I would use the 80 column RGB screen for program output, and the 40 column composite screen to print the output for debugging the program. That way debugging output wouldn't foul up the carefully constructed program output.

I think this is on the thread topic. When I programmed on the 128, I would

Ditto, except when I did it the monitor roles were swapped and the 80-column
was only a monochrome green screen. Nice and sharp, though.

To preserve any composite screen graphics, you would need to print your text on the RGB screen. I didn't use 2 monitors, just a monitor with a switch for toggling between composite and RGB screens.

Pretty cool, I don't have a 128 but I watched the YouTube video.
Ahoy! Magazine published a cool two-player game for the C128 called Dark
Fortress that used two monitors.

I augmented my Macro Assembler Development System (MADS) with a module that among other things, transfers a C64 composite screen to the RGB screen. I can configure the RGB screen in double pixel (40 column) or standard RGB 80 column displays. When in double pixel mode, the composite screen is transferred to the left side of the screen When in standard mode, the composite screen is transferred to the right side leaving the left side undisturbed. I can view 2 C64 screens at the same time. Unfortunately, only a snapshot of the C64 screen is transferred. The RGB screen is not continuously updated. Recently, I had to connect the C64 A / V output to a WINDOWS 7 video capture interface while doing some MADS chores. The monitor was disconnected from the A / V display. The MADS RGB capability showed me the action on the monitor's RGB screen.
