Believe it or not, this very problem has bothered me to no end in the past. Especially because I want the "black" in my monitor/TV to be REALLY black, to provide a more vivid contrast to the color of the screen. Even when I turn down the brightness, I can't get a darker black.

I could have sworn that I saw a very similar article show up a month or two ago.
Edited to add:
quote: Pendry added a cautionary note about invisible cloaks, making a real-life distinction from the stuff of fiction: People inside them will not be able to see out. By definition, if no light is bouncing off them, none can reach their eyes, either. "You'd have to use signals other than light to communicate," Pendry said.
These sound really similar to the cloaking devices from Timothy Zahn's Thrawn Trilogy.

Blayne, CRTs - the actual tube itself - must be slightly biased when on. Even at black there is some excitation of the phosphor coating on the screen. Using the power management rather than a screen saver will turn off the crt, save power and extend the life of your monitor.

That's possible, although I'd guess that he probably has an LCD monitor and is talking about the backlight.

That was my guess. My laptop constantly his a brighter black screen than I would like. But it's just something that is built into them. Oh well.

Until very recently, the lighting system used by LCD monitors has made it very hard for them to reach the same kind of dark blacks achieved by CRTs.

I didn't know the gov't had a standard. Is there a standard for the whitest white? Or the reddest red? Where do they catalogue these things and is there a specific department that handles it? The Department of Colors? The Agency of What Things Look Like?

It is often the military. All those billions and billions of dollars, and one of the ways to make sure they get what they pay for is to make standards for absolutely everything that can be bought.
This includes cookies. There is a military standard for an acceptable chocolate chip cookie.

Really? That's great. I wonder if they have a position open in the Pastry Standards Testing Department. What a sweet gig.

I don't know if it's the "whitest" white, but titanium dioxide is probably the most common standard for a consistent white.
