Just trying to get the best pic...it's a little dark, but that can also be from my 4000 hours I've put on the PJ.
3D always takes a significant hit in brightness compared to 2D. If you think about it, any pair of 3D glasses (even passive ones at a theater) drop brightness significantly. Then, remember that when Active glasses are in operation, at any given time, only one of the two lenses is actually 'open' (and there's even a portion of time per cycle - during the red-flash sync - that both are closed); so it drops even more in operation.
And of course, at 4000 hours - your lamp has dimmed somewhat! (What lamp power mode are you using? If you're using Eco, then swap over to SmartEco or Normal mode to gain brightness in 3D with very little loss of quality to the image.)
In terms of compensating to increase brightness, the three controls that are most helpful are Brightness
(under advanced picture settings).
You have two preset modes to play with in 3D: the default one (simply called 3D); and 'User 3' (which could be renamed if you wanted). Changes made to either are saved.
For brighter 3D movies, I've left the default settings almost in tact but just dropped Gamma by one point and I'm sorted most of the time. (Pushing Gamma too low washes the image out; so you'd want to go easy on it.)
For dim movies, for the second preset, I've dropped Gamma one point as well, and in addition, pushed up Brightness (by about 2 points or so) and Contrast (by 3-5 points).
Once again, pushing up brightness increases black levels and pushing up contrast introduces bright-color/white clipping; so you'll want to take it easy here, too.
Experiment with those three controls a bit (along with lamp mode) and determine what looks best for you in your setup. Hopefully, a one-point drop in gamma (along with SmartEco/Normal lamp mode) is all you need for most of your content.
