Things I don't miss from CRTS: Their weight, the heat they put off, eye strain caused by low refresh rates (below 75hz for me), having to adjust the rabbit ears or outdoor antenna when one of the 4 channels got too snowy, image burn in.

Things that I miss from CRTS: black is black not grey, console tvs and tv's as furniture, better viewing angles as people didn't mount their damned tv over a fireplace or up high in general, turning the brightness knob down if it too bright at night, video games (of course),

Adding one not-missed item to the list: the annoying high pitch whine

Even worse when your grandparents couldn't hear it and thought it's perfectly OK ta have TV buzzing 24/7 in the background.

15KHz aprox. Not every body notices it

At what age does it go away to hear this?

I'm in my late 30s and I still hear it. But seemingly none of my co-workers can.

I know because once one put a "test your hearing" website and they all thought it was a sham until I told them to cut it out with the annoying whistle.

But I thought by now I would no longer be annoyed by those.

Probably I'm less annoyed than before.

That's only for TVs, though. Computer monitors had higher refresh rates and were not audible.

I could hear them. They can't have been that high.

What you hear is the horizontal refresh rate, scanlines per second. For NTSC television and CGA video, that's 15.7 KHz and within the audible range of quite a few humans. 640x480x60fps noninterlaced VGA is twice that at 31.4 KHz, which mostly isn't audible although a very few exceptional cases might. Higher resolutions are higher still, of course. That said, as with anything involving analog frequencies, there might be harmonics or resonances that could be in a range you can hear.

I could definitely hear CRT monitors at resolutions well above 640x480, so it can't have been the horizontal refresh rate.

I remember that I always noticed the sound when someone turned on a TV or CRT in my house when I was growing up. I miss that.

That depends on the age of the computer monitor. Older ones could whine.

Try OLED it solved the black, the viewing angle, the video games look insane, the near zero bezels make the image seem floating and well a remote control can adapt brightness well.

It did? I thought they're advertising themselves based on how effectively they can blind you.

You could turn down the brightness on a CRT down to 10% or less at night and still use it.

Why can’t you turn the brightness down on your lcd?

Random explanation :) It tells you how to blind yourself more, but it's valid if you want the other way too.

Although they say it's for TVs, it goes for LCD monitors too these days.

Not to mention that whatever you turn down on a LCD monitor will mess up your colors beyond a point.

I do this almost daily.

Daytime is bright. Nighttime is not. Why shouldn't my monitor follow?

You can, but people aren't going to bother, when it's three levels deep of on-screen menus, accessed with tiny buttons, mounted in an awkward place, labeled with cryptic icons. Much more cumbersome user experience than turning a single dial on a CRT.

I'll turn my LCD down, but it uses LEDs for back lighting and will only go so far at night or else it would start flickering. Most CRTs I had had a knob you could turn, and you could keep turning it down till you can't see the image anymore.
