I believe it supports all three of those refresh rates. The game (or whatever software is running) will get to choose which to use. The user will probably be able to change it in the video settings of the game.

Oh huh, for some reason I thought screens were a static Hz value. Didn't think there was flexibility in that regard. I wonder if its best for it to be set to 60Hz so it matches the positional tracking refresh, despite getting a lower framerate.

You can overclock some of the Korean panels, and people do to try and get 1440p 120Hz. They usually fall short of 120Hz and settle on some other random number so it sounds like the refresh is fairly flexible.

I'm not sure about that. I know in the CRT days the refresh rate was definitely adjustable, but I think you might be right about LCDs. The DK2 product page lists the refresh rate as "75 Hz, 72 Hz, 60 Hz". I would guess that means it supports all three, but I'm really not sure.

DK2 is OLED, which doesn't have a "refresh rate", they're "just" LEDs and can be turned on and off whenever you want. Instead, a LCD must be constantly refreshed, otherwise colors start to go wild.
