Comment on I love my smart TV (From Mastodon) - Repost

Again, I’m sure they exist, but at comparable prices?

That’s a room treatment issue. You need to control light and reflections, because your “black” is just however dark the projector screen is.

Is that true? Because I was under the impression that even the darkest “blacks” from a projector, are still made from the light coming from the device. Which is not necessarily the same thing as a pixel on an OLED TV being set to “off”.
But I am far from an expert. Also, as I said, I’m sure some really amazing projectors are out there, I just imagine they’re cost prohibitive for most people.

You’re probably thinking of contrast, which is the ability of the projector to avoid bleeding light into areas that shouldn’t have any. But as far as the darkness of the black levels, that’s down to room treatment (and the screen surface, to a lesser extent). After all, a projector emits light, and darkness is simply the absence of light. You can’t “make” darkness, you can only remove light.

I understand all this… But when I watch a movie, the “black” that I’m seeing in a particular scene isn’t the absence of light, because it’s not actually “black.” It’s a very very dark shade of grey or brown or whatever. And that requires light. Even if there is some actual “black” (spots where no light is coming out of the projector), there will still be a gradient, and immediately after “no light,” you will have a light attempting to project a very dark shade. And that will need light from the projector to display.
Maybe there is a way to encode a video for projector that accounts for this, I don’t know.
