That's very difficult.

And various technologies for stopping you from seeing that entire backlight have been tried over the years, but they can't stop all the light, which is why if you take the studio display, put it in a pitch black room and make the studio display show a black screen, it will light up your room.

Because that's just the way it is.

And then as you go down the spectrum, okay, let's break up the backlight into a bunch of little pieces.

And then we'll just turn on the little pieces that are behind things.

So if we have a single white pixel in the middle of a black screen, we'll just turn on like a one inch by one inch square behind that pixel.

but then you get a little glowing region around the one-inch pixel.

People refer to that as bloom.

It's very difficult, again, to keep the light.

The other parts of the monitor don't have any backlight turned on, so they're totally black, but the little pixel has a little bit of bloom around it, so you try to turn the backlight down a little bit and combat bloom.

And anyway, that's one whole section of television switches.

We cannot turn on individual pixels and make just the pixel emit its own light.

We always have to turn on some portion of the backlight behind the pixels that we want to show up.

And those regions have been getting smaller and smaller.

It used to be like, oh, we divide it up into like five regions, 16.

Now there are thousands of backlight regions on like modern displays, not the studio display.

But, you know, Apple's Pro Display XDR has, what, 570-something backlight regions?

And that's like a six-year-old thing.

The monitors we were talking about from CES are like 2,000 zones.

But, of course, how many pixels are there on a 5K display?
