Video projection is like a whole other system. Light control, being able to darken the room, and the screen, are almost equally important. The most important factor in video is contrast. Most people with plasma are used to watching with a lot of room light. But there's a reason every movie theater is dark. And red. With a big screen the light off the screen itself reflects back onto the screen washing out the picture. Even the background color affects your perception of screen colors. There's a reason my room is painted a fairly dark neutral gray. And the screen is a Grayhawk, same brightness and color but much less washout. https://systems.audiogon.com/systems/8367 Also the wire you use matters just as much as with speaker cables. The difference with a really good video cable is like going from 1080i to 4k.
There's really no point in buying used. You will figure out after some years the bulb thing. Just buy new. By which I mean new new, not last years model new. And don't waste money. There's a ton of people throwing $5k to $50k and more, and you have to strain and get technical to see any difference from the $2500 model. There's more difference by far to be had from the cable, screen and room that anything you can get for any amount of money if those aren't all optimized.
That's why I say projector people. They know projection.
