I recently connected my A1000 to an Intec multiscan moniter (this moniter
is also marketed under the brand name Samsung) using an appropriate
cable (i.e. analog R,G,B, HSYNC, VSYNC, and 4 GND lines.)  The Intec is
a VGA-compatible moniter that accepts analog or TTL-level input.

This multiscan performed flawlessly when the Amiga was displaying a
non-interlaced screen.
An interlaced screen, however, showed an incredible amount of flicker, much
worse than my 1080.  Upon closer inspection of the CRT I realized that
the odd and even frames were being SUPERIMPOSED on each other rather
than being displaced by half of a scan line.

Question: do any multiscan moniters correctly handle interlace, or is it
just this particular brand that fails?  Or am I doing something else wrong?

The reason I'd like to get a multiscan is that I have to let go of my
1080, and I want a moniter that will work with my A1000 now and with any
future Amiga I get that may have a higher-scanrate output (like a
flicker-fixer or the enhanced chipset.)

Thanks,
