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…

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

It wasn't until I was shopping for an LED TV that I really understood a lot of the important details in how a sequence of images can be made to look like the images are in motion. The biggest revelation was the difference between showing a still image for just a moment vs holding that still image on screen for a long time. Illuminating the screen pixel-by-pixel with a short duty factor gave CRTs sharp crisp motion co…

That would not look like 30 fps necessarily.

The keyword you want to learn about is “Shutter Angle”

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?

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.

In the Super Smash Bros. Melee competitive scene we still use CRTs for in-person tournaments because of the input lag on LCDs. Most original hardware available to play the game doesn't have a digital display output unless you have an early model GameCube and purchase a ~$100 HDMI adapter. Even if you get the hardware setup for modern digital output, most LCD monitors still have poor response times without spending th…

> work by modders to reduce the input lag introduced by the game engine itself Can you link something about this? are people rewriting the core engine of melee?

A few projects that are pretty widely used in the Melee scene are 20XXTE [0] and Slippi [1].

As far as I know, neither rewrite the core engine of melee, but there are some key modifications like UCF (Universal Controller Fix) in 20XXTE that modifies the way the game interprets analog stick movement to help standardize the effectiveness of gamecube controllers. Without that fix, it's very hit or miss on whether or not certain movement tech would work consistently on a controller due to joystick drift / deadzones.

Be aware of the energy you are wasting, a modern tv uses much less power than a crt.

Depends on what modern TV since most people are buying bigger TV's now. An 28" CRT uses about the same amount of power as a 55" OLED so replacing the former with the latter does not improve energy use. Besides that, energy is not wasted if it's used to make pretty pictures ;).

Of course but to make an intelligent decision, one needs to be aware of the costs.

I can't imagine loving a monitor the way I loved my iiyama Vision Master Pro. 1600x1200 at 71Hz driven from a Matrox Millennium (4MB VRAM and no 3D acceleration whatsoever) with soft-edged pixels and no visible grain or mesh. It was by far the best computer-related object I had ever owned. But that would be so impractical now, given its bulk and what else is available. We actually still have a CRT as our main TV here…

Manufacturing the new TV costs energy. When you buy brand new you’re just paying the energy cost upfront. Depending on the usage this may or may not break even.

That's right, my example was off because film is 'usually' shot 180 degrees. So 30 FPS has an effective shutter of 1/60", and 120Hz open shutter needs a 2-frame sliding window to match that look. Or use a 3-frame window for 1/40", a more blurry film (1/48") look. There's power in being able to make that choice when editing.

What I'm not sure about is how similar merging two images together will be compared to doing it natively with the camera. I'm guessing it will look slightly different, but I'll find out when I try it.

When I was a desktop tech, visiting a user with a problem, I carried a laser pointer with me. I could point to elements on the screen without getting my fingerprints on the glass and without invading the user's personal space. Laser pointers are pretty much useless on LCD. Not that I would ever go back; but it was a nice feature at the time.

> Laser pointers are pretty much useless on LCD.

What do you mean? An LCD will reflect a laser pointer just fine (I just tested it).
