I have had the 3DC-1000 in my set up for several years and never had an issue with 2D or 3D.
My set up: Sony Blu Ray Player --> Denon 2311 ---->3DC-1000---->WD-73737
I went to watch "This is The End" blu ray and the feature was very dark and washed out. All of the previews and additional content look fine.
I thought maybe it was the disk but the feature looked fine on different system. I then swapped out blu ray players and still had same issue.
Pulled out other 2D blu rays, no problems
I finally bypassed the 3DC-1000 and the picture looks fine.
Any ideas on what is happening?
