I thought the Macbook Pro LCDs were bright enough, high-res-enough, and fast enough to make a very accurate CRT simulation. Here it is: <a href="https://github.com/baragona/crt-xdr" rel="nofollow">https://github.com/baragona/crt-xdr
It looks so much like a CRT to me. It looks like pressing your face up to a TV to see the individual phosphors. Try setting "signal" to dropped image and viewing some images. It looks like an old TV.
Bottom line, whatever you think a CRT is doing, you can probably simulate it quite accurately.

  You can’t simulate the motion clarity of CRTs (yet).

    You don't want to simulate the god-awful flicker my CRT has at 60Hz.

    The hysteresis of the phosphor makes this a non-issue in reality. 60Hz looks great on a CRT when the input is a game console or VCR from the era.
    Maybe you mean screen tearing, bad deinterlacing, etc. caused by software running on a PC?

    No, I mean the screen noticeably flickers when displaying a static image at 60Hz progressive.

    I mean... are you bobbing and weaving your head while rolling your tongue or what?
    I get that CRTs aren't perfect, but I'm not sure how else to reproduce what you're calling "flicker".

    perhaps was 60hz interlaced. I had memories of my first CRT monitor only allowing to do 1024x768 in interlaced and doing a very obvious flickering. But was flicker free at 800x600 and lower resolutions.
