A1200 and A4000 could be hooked into a VGA monitor for the flickerless experience. The caveat was that the flicker-free display modes were added on top of old ones, which meant that, while you could run Workbench and most applications on the VGA monitor, all games ran in the obsolete PAL modes your VGA display couldn’t handle. This created a market for niche dual-mode displays, which solved the problem, but were a bit pricey.
