Trident cards think a Colour Monitor is Monochrome

Trident card that thinks Colour Monitor is Monochrome | Vintage Computer Federation Forums

What is happening is that on the VGA port, the monitor uses DDC for “detailed” monitor ID, rather than simple open and closed pins for colour, mono, etc. The DDC signals can fool the Trident card, intermittently causing the card to boot up in either colour or mono. You can recognise this when the TRIDENT sign on message during POST is either colour or mono.
