Begging your pardon, BTC, but DMD micro-mirrors only have two states, "on" or "off", typically + or - 10 or 12 degrees. They're binary. They don't have varying degrees of pitch anywhere between the "on" or "off" positions:

https://en.wikipedia.org/wiki/Digital_micromirror_device

That said, I might have inadvertently answered my own question to some degree, as that same link above describes how it is the ratio of "on" time to "off" time that determines the intensity of a given primary color.

So it's not so much a matter of being able to flick 1,024 times for each color of each frame, but simply being able to flick once quickly enough to allow a level of precision that could result in one "on" state with all the other states being "off" (or vice versa).

So I guess it's not so much being able to flick 368,640 times per second; it's being able to flick from "on" to "off" (or vice versa) in 1/368,640th of a second - heh.

Is it actually faster than that because of the color wheel? I'd have to imagine the RGBRGB color wheel in the UHD65 is a "6x speed" wheel. But since the same wheel and the same chip are being used twice per frame, it's really more the case that each individual pixel will get a sequence of red, green, blue shone upon it 3x per frame rather than 6x. Although...physically, it's one micro-mirror being used to create two pixels per frame. So that one micro-mirror is getting red, green, blue 6x per frame again.

Man, this starts to get confusing! haha.

But to simplify, if we just look at the task of a single micro-mirror in the DMD, it's essentially running at 120Hz (60 fps, but being used twice per frame), and it's being hit by a sequence of red, green, blue light 6x every 1/60th of a second, or 3x every 1/120th of a second.

So cumulatively, each pixel that gets displayed has red light shining on the micro-mirror for 1/360th of a second, green light for 1/360th, and blue light for 1/360th. And cumulatively, the micro-mirror would have to be able to flick from its "on" state to its "off" state (or vice versa) fast enough to be "on" for only 1/1,024th of THAT, and "off" for the other 1,023/1,024ths (or vice versa), which is...

1/368,640th of a second.

OK...so there ya go.

Whelp, I can be satisfied with that. That's still mind-blowing and remarkable. But as long as each micro-mirror can flick from its "on" state to its "off" state in 1/368,640th of a second, then 10-bit color at 60 fps from a single DLP chip should be possible.

Alrighty then :)
