Mine is white... the frame is black. I'm very happy with it, only the assembly was a bit fiddly.

Yes also white here; what surprised me was that the instructions say -> Not suitable for ultra-short distance projectors... as the picture would then supposedly be too dark. I don't see any difference, but I also have no comparison...

Mine, which I am currently selling secondhand, is also all white (no black frame)

Mine is all white; only the corners would be black if the (black) corner protectors were fitted.
I had it installed by the suppliers and haven't regretted it for a minute.
