Is that the norm for Christmas Carol also?
I just got a new 3D ready pioneer receiver a couple weeks ago so I have my blu ray player running through that now (I have the Samsung 7900 player with 2 hdmi connections. Before I was running the audio to the old receiver and the video directly to my tv, both via hdmi). I guess my question is, could I be noticing more ghosting now because my blu ray player isn't feeding the video directly into my tv? Could running my player through the receiver first actually cause my display to create more ghosting? Thanks
Crosstalk is display
related (that is, true crosstalk does not result from the content, except in that certain content such as bright/high contrast scenes can reveal it more than others). Crosstalk is defined as the leakage of content intended for one eye into the view perceived by the other eye
Doubling, or ghosting, can also result from parallax/convergence issues (a failure of the eyes/brain to resolve the L/R views if they are displayed too far apart). This can result if the material is mastered with greater than recommended positive parallax ("depth"" or negative parallax ("pop"). To determine if you have true crosstalk, close one eye while viewing; if the double image persists, you have true crosstalk. If not, try adjusting the "3d depth" setting on your display, or your seating position, to address the convergence issue.
For true crosstalk, the first step would be to calibrate your display, because proper brightness/contrast settings (or more accurately, black level/white level settings) can minimize the problem. However, crosstalk will never be eliminated for certain display types; LCD tends to do worse, while DLP has better 3d performance. Viewing angle will also come into play with passive LCD.
One thing you can do, if you are using active shutter glasses, is upgrade to a glasses/emitter setup that has the ability to adjust the delay & duty cycle of the shutters, such as the Bit Cauldron RF system (also rebranded as Monster Vision, VIP, Optoma RF, etc.). This will let you dictate when the shutters "close down" for each refresh cycle, in order to minimize the instances of the right eye being open when the left eye view is displaying, & vice versa.
