I have been using this projector with a windows 10 pc and nvidia card for a few years and have had no problem. Last month I was unable to view 3d. I updated the computer and video card drivers and software to no effect. I understand there is a firmware update for the projector. Would this make any difference? Could it be a cable issue?
Has anything changed in the last month that would affect the 3D? cable, software, content?
If you happened to change cables or add a HDMI splitter that is not HDCP compliant, then it may stop working.
There is a firmware that helps with the timing of 3D but if it worked before then it should work.
If you would like to send in your projector we can flash the firmware to the latest for you.
it still shouldn’t stop the playing of 3D movies unless something has changed.
