I installed a shiny new 3D projector — DLP, which so far are the best kind for 3D performance. I popped into the player a demo Blu-ray 3D disc I always start with, and it only displays in 2D.<\/p>\n
So I fiddle with the projector’s settings. Still 2D. I switch the receiver and player off, and then back on, with a view to them re-inialising their HDMI settings so that they can correctly detect that they are attached to a 3D system. Still 2D. I unplug and replug-in the external 3D sync transmitter. Still 2D.<\/p>\n
I switch everything off, then plug the 3D Blu-ray player directly into the projector and switch it all back on. 2D. So far, all has been via HDMI 1.<\/p>\n
I go through the projector’s menu system very carefully, item by item, to see if there is some kind of 3D enable\/disable function. No. I consult the projector’s manual to see if I’ve missed something. Apparently no.<\/p>\n
I try a different Blu-ray 3D player, plugged into HDMI 2. Eureka! 3D!<\/p>\n
Time to plug the first Blu-ray player into HDMI 2, since HDMI 1 apparently doesn’t support 3D, although I can’t imagine why. As I switch the player on a thought occurs to me. I take action as a result.<\/p>\n
Yes, we have 3D! I switch off the player, replug it into the home theatre receiver, and the receiver to the projector back into the original input, restoring the very first setup I had. I switch on the player, and yes we have 3D!<\/p>\n
What action did I take to resolve the problem?<\/p>\n
Answer over the fold.
\n
\nThe action I took was to press the ‘Stop’ key for the Blu-ray player twice.<\/p>\n
Simple, huh?<\/p>\n
But why?<\/p>\n
The disc I was using is very basic. It has no BD-Java code. Most Blu-ray players will restart such discs from the point at which they last stopped. Which is what was happening with this disc.<\/p>\n
And normally, that wouldn’t be a problem. But it now seems likely that the last time I played the disc I was using my own 2D projector. The Blu-ray player must have remembered its play state from the last time it had played the disc, and that would have included its 3D state. I don’t think it was due to it possibly playing a different Blu-ray playlist, because according to my analysis of the disc, it only seems to have the one playlist.<\/p>\n
Anyway, hitting the stop key once stops play. Hitting it a second time cancels the resume play mode, so that the disc is treated as a fresh one. The disc is re-read, identified as having 3D content, the player queries the system afresh and confirms that it handles 3D, and on we got to proper 3D playback.<\/p>\n
Simple, huh? Except for the hour of fiddling around before I fell upon the answer.<\/p>\n","protected":false},"excerpt":{"rendered":"
