    so dvi and vga side by side ?

    that could work. as you say, set a base line. swap outputs to confirm baseline.
    insert random LCD panel

    Yes, absolutely doable. Find/create a 60FPS video with a frame counter baked in, set your OS to screen mirror mode, play on two screens at once.

    For ultimate reference, use a zero-lag VGA DAC into a CRT on one display.

    Yes, thousands of 4:3 tate video games out there.

    Also remember "tate" is not an acronym. No need to yell it in all caps. :)

    what do people make of this whacky technique? I think it sounds fucking stupid, but what do i know - this guy knows stuff.

    The main thing that offends me is calling it the Konami Code of "CRT sharpness". I kind of want to give him a good uppercut for that alone.

    What is "screen"? Are they talking flyback voltage?

    [edit] I stopped being shit and read. G2 voltage, which should be in the order of a few hundred volts. (Exactl numbers are usually in service manuals).

    What do I think? I think CRTs are a pretty fine balance of voltages internally, and dicking around with them can lead to shortening the lifespan of components. If a CRT is lacking in fine controls for colour and focus, that does suck, but potentially ruining the thing by over-driving internal high voltage circuits can be a bad idea if you don't know how to measure things safely.

    yeah ramping the voltage seems silly, this guy is fucking with 50 year old tv's too.

    Definitely a quick path to shortening the life of your CRT.

    Given that they're finite in number as well as humans who can fix them, I wouldn't.

    It's funny with rare old stuff, almost seems to come with a sense of social responsibility.

    Sounds like another shithouse essay in the making. :)
