The laptop has to supply sync-on-green for a simple adapter to work. Can you interrogate
the video output mode, or change it, to make interlaced 60 Hz video with sync-on-green?

More flexible (expensive) adapters actually include frame buffers, and require a power supply.



Used Extron scan converters show up on Ebay for reasonable prices.
VGA to S-Video or composite are common models. There is a steady stream
of older hardware being pulled out during upgrades to digital and mixed
video systems.
