So I asked, “What will happen if you hook up an NES directly to a projector?”
I’ve been wondering about this since I was a kid.
Now I know the answer: it’s awesome! No input lag. You don’t have the same problem of “raw” pixels as you do on an LCD or LED. But at the same time, you don’t get the scanlines that a CRT has.
But the biggest advantage is that the light is much softer which reduces eye strain if you’re in a dark room.
Maybe you use a better projector than I did one time, but in my experience they are a recipe for massive headaches and pretty much the worst eye strain.
