the alt-pg up/dwn feature to adjust brightness is pretty great. the fact that it rolls back in the morning is pretty clever, i always found myself having to fidget with settings on my monitor.
I'm speaking as a colorist working in film/television here. TV's already have enough issues destroying the look we carefully craft with "features" like dynamic lighting, motion smoothing, vivid mode, etc. A huge color shift is going to throw this off even more and dramatically change the look and tone to the detriment of the work. This is great for reading text on a screen, but should be disabled for viewing media - you wouldn't look at the Mona Lisa with amber glasses.
Often the creator does not have all that much control over how their work is consumed. (And I guess it's not worse than reading a novel in a loud room, in some sense.)
I cannot watch TV with any sort of motion smoothing enabled. When watching other people's TV's I usually offer to "fix" the image, but in the end most prefer it enabled.
It is pretty great, however it cannot be changed to another key combination and if you happen to use that particular shortcut in some other apps (cough OneNote cough) you're pretty much screwed.
They used to. My grandfather had ancient color TV when I was very young that used a photo sensor to adjust itself to the room lighting's color balance.
They still do in that they can automatically adjust brightness based on light environments. Just brightness / backlight setting though, not colors or anything. I have it turned off and have it set to the lowest, given how it's still too bright even if my room is pretty dark.
i wish more devices, like tvs, had flux baked in.
