In my childhood, my father was an independent electronics repair technician, which meant that sometimes we would get goodies that people didn’t want to keep. One of them was a professional Barco CRT projector that was about as big as I was and about five times heavier. We kept it in a dedicated room that only had a single window for some reason. The screen took up the entire wall.
This guy makes a big deal about how difficult it is to adjust, and to be fair, they absolutely are. But they are also not meant to ever be moved. That barco projector from my childhood basically couldn’t be moved; it was stuck on the dressers until we trashed it because we needed the room for someone to live in. So the vast majority of adjustments are meant to only happen once, and only have minor (software controlled) adjustments done from time to time.
There isn’t anything wrong with that guys projector. Pretty much every CRT projector has that exact same problem with the red channel, even with rear projection tv sets. Ive seen red fringing on pretty much every one of the thousands of CRT projectors I have seen. I can’t recall exactly why it is, but I believe it has something to do with how bad people are at seeing the red channel. I think it probably needs to be overdriven and it causes the red channel to wear down from heat faster. CRTs are kind of weird compared to modern displays; the geometry can move around and distort depending on if and where bright parts are in the image and how long. So it could be the opposite problem and the blue and green channels are wearing out faster than the red.
While I have a rose tinted picture of CRT projectors myself, I know it’s all nostalgia. This guy can be happy for how crisp it is because he has an absurdly expensive model that was capable of super high quality video and is also extremely compact. In reality, pretty much every other example was a big blurry mess. Rear projection TVs could theoretically be made to be any size, but the reason why they didn’t go too big wasn’t so much because of the brightness and more of SD content just not looking good when it’s exploded. At some point it just starts looking like a wall of color changing Vaseline.
That projector was basically the reason why I decided to never mess with projection. LCD projectors were great for showing a lot of people what is going on on your computer screen, but it was horrible for video. It didn’t matter if it were brighter because brighter bulbs just meant more washed out colors and lower dynamic range. All digital projectors had issues of being extremely expensive if you wanted full resolution. DLP offered major improvements but the problems with them was that they were kind of transient; they needed specialized bulbs that burned out frequently and they also needed mechanical color wheels to produce color, which could also burn out. Our shop made lots of easy money replacing those. And beyond everything, having an absurdly large screen taught me that there was such a thing as too big of a picture. Forgetting how bad SD content looked on a huge display, it ended up taking you out of the scene more often than it should would draw you in.
