When I get back home I'll have look further into it but I have an Optoma Hd28dse projector with 3D enabled and a Sony UBP-x700 DVD player with 3d enabled (auto). I am trying to watch Avatar 3D and the menu works fine but when I try to play the 3D version I am told " The Blu Ray player requires a 3d display and it does not recognize one as connected." I've turned the projector on first and in different 3D modes then the DVD player with no luck. I've tried other/shorter hdmi cables (plugged 3ft from the projector) and same error. Could these DVD players need a factory reset with the projector in 3D mode possibly? Seems like it should automatically notice a 3D display upon bootup and not need this.. Believe my HDMI is 1.4 but even if it is 1.3 it should at least work correctly even if it wasn't full 1080 resolution correct? Any insight would be great. I'm a tech guy and I know there is something I'm missing.
