If I buy one I’ll get the $899 retail version:
I want the controllers for other games.
I don’t need the Lighthouse panel, because I’m fine with its inside-out tracking (Lighthouse adds base station capability, which probably gives you better tracking, but not really needed in the sim.)
The $699 version doesn’t have local dimming, and uses only QLED (i.e. no Mini LED.) It does come with controllers, but I want local dimming and the Mini LEDs.
Everything else on all three versions is the same.
The Crystal Light connects to Display Port for data, and a USB-C for power. No battery, no wireless.
