Why did 1990s-2000s LCD all use 60 Hz refresh?

To be fair, cost, need, and usefulness of anything above the standardized 60 Hz minimum for different resolutions are the reasons why it took long for LCD monitors to go past 60 Hz. The LCD panels ...

LCD Displays with the Intel 8080

The 8080 is not a microcontroller, but a microprocessor, so it had no special provision for LCD displays, as modern microcontroller may have, except maybe for the ability to use packed BCD numbers. It ...

What sort of LCDs are used by the Game Boy/TI-83 calculator/etc.?

The original Gameboy, which I assume this is about, is, as Wiki states a Reflective, 160 × 144 Pixels, STN LCD. Reflective means that it has no backlight nor other means of ilumination but simply ...

Why do sprites lag behind a scrolling map in first-generation Pokémon games?

Well, there's a fifth one: A sequence issue not really considered relevant when first published. The underlaying issue is that sprites are not moved during scrolling the background, prior to (re)...

How do you remove an LCD bubble on an unmodified Game Boy?

Why did 1990s-2000s LCD all use 60 Hz refresh?

One benefit of high refresh rates on CRTs is to re-energize each phosphor more frequently, so decay between scans is less. And any pulsing of brightness happens at a frequency well above human ...

Why did 1990s-2000s LCD all use 60 Hz refresh?

I would say that 1990s LCD displays did not use 60 Hz refresh. At least the one I had on my first laptop in 1997 was a passive matrix display, with 30 Hz refresh rate and very slow response time. Not ...

Invert LCD screen in DOS 5.0

Seems to me that the way to go would be to re-program the lookup table use by the digital to analog converter (DAC). The DAC is essentially the last component in the VGA, taking 8-bit VGA colors and ...
