I have triple monitors working with Mojave out of the box. I have dual AMD 280X graohics cards.

I got them working after weeks (months) of messing around with DVI ports which worked well under High Sierra. I could get two monitors working under Mojave. I then switched to DisplayPort and to HDMI and it just worked.

Pure luck I stumbled on it. No idea if this helps.
