Without double checking the specs I believe it has two 12v triggers. I’ve looked at various DIY masking techniques, the pre-made ones are just to rich for my taste right now. My initial plan was to make masking for both 1.33:1 and an adjustable one for 2.35, 2.40, etc. . . .
Probably going to go the cheapest and easiest route first and just make them from velvet covered foam insulation that just hangs from the top of the screen. Later once I’ve actually got everything else finished I’ll start looking at what improvements I can do to make things more user friendly at which point some form of automatic masking may be in the cards.
Most of my resolution changes right now are between 1.78:1 and 1.33:1 with only a small percentage of my viewing in the 2.35 range.
