A comment on Night Shift Mode in macOS Sierra 10.12.4.

Has anyone produced a screen that isn't backlit in recent years? I see there's a 13" e-ink display (https://www.indiegogo.com/projects/paperlike-world-s-first-e... ) but I don't know if it needs to be e-ink or simply not backlit. I worked last night to candle light and it was lovely; would like to be able to do the same on computer.

Perhaps it's worth finding an old monitor to kill the backlight on to try this out.

You needn't bother. Having repaired a considerable number of displays with dead backlight inverters, I can say from experience that you won't be able to see anything.

(Light has to pass through an LCD in order to produce a perceptible image. Watch displays, pre-backlight Palm devices, non-backlit e-ink displays, and the like do this by reflecting back light that arrives through the screen. Computer displays all but universally do it with a backlight; without one, and without a reflective layer behind the LC layer, you see a blank black rectangle no matter what the crystal layer is doing.)

If they're gonna kill the backlight anyways, I doubt it'd be much effort to put something reflective where the backlight was.

You'd be surprised. Getting good light reflection without also producing an image of the surroundings to conflict with the display is harder than it seems.

Amoled screens can go really dim. As dim as reading by candlelight, while retaining most color detail. But I don't think we will get an amoled computer monitor anytime soon, if at all.
