Fun fact: two of the "problem" machines turned out to have nothing wrong with the boards at all, a badly soldered CPU socket and a leftover blitter patch bridge were the actual culprits. Moral of the story: check your solder joints twice before blaming the silicon.

I have three of them: a passive MCSWITCH adapter on the "Low" machine, a self-built adapter on the "High" machine, and a newer active ST2VGA Enhanced that isn't in use yet.
+ +The Mega ST 4 "Low" uses an MCSWITCH adapter (ATARI Monochrome & Color VGA Adapter) by Olivier Gossuin. It shows all three ST resolutions on a suitable VGA monitor, with a switch for mono and color, an A/V connector, and volume buttons. It's documented on albersdoerfer.de.
+ +The Mega ST 4 "High" uses a self-built adapter. I followed the guide at pest.atari.org to build a simple RGB-to-VGA adapter for the Atari monitor port.
+ +I also bought a new active ST2VGA Enhanced from SidecarTridge, but it isn't in use yet. Unlike the passive adapters, the Enhanced adds an active amplifier and filter stage for early or noisy Atari machines, and carries its own +5V supply over micro-USB. It's designed for machines with weak video output, visible "jailbars", or picky LCD inputs that fail to lock to the signal.
+ +Passive RGB-to-VGA adapters output the Atari's native timings, so color modes (ST Low and ST Medium) need a monitor that can lock to a 15 kHz horizontal sync signal. See my monitor compatibility page for which modern panels actually work. Mono mode (ST High) works on any standard VGA display.
