Hi,

I really, really wish that what I said were incorrect.

While LED light is constant [EDIT: not true. See post #44] and has improved the viewability of computer screens, backlighting is separate from the display itself and the actions of its pixels.

Regrettably, LCD pixels do turn on and off that often. The refresh rate (60-90Hz) refers to the display, not the backlight. It is what makes LCD capable of both showing quickly moving images and irritating to the eye.

[EDIT: I was incorrect about all this. See post #44]

I appreciate that it is difficult to understand, because it is so simple, so basic a need: just to read and write in response, in real time. Notes, essays, letters (which is how I think about email), and comments. You name it, I don't want to do it on LCD anymore.
