Recently replaced bulb in my MARANTZ VP11s2 projector. I started to notice this weird thing happening in A LOT of darker scenes (or portions of scenes .... like backgrounds that were out of focus) in the gradation from dark to light - particularly on faces. It looked almost like solarization. I researched and I THINK this is called color banding. It's like what should be a smooth gradation becomes defined lines. Hard to describe.
The thing is - I had never seen it before. My installer checked cables etc and all was fine. Finally, just to cover all bases, we reinstalled the OLD bulb (thank goodness we kept it) - and VOILA - "banding" is gone.
My installer is going to put the new bulb back in and see if the banding returns - but I was wondering: has anyone ever experienced this???
Also - since this projector is getting old, I have been looking into getting something new. My installer recommends the Digital Projection Cine 260, but I got to test drive their super bright 400 model (with its settings kicking down the lumens to @ 2500) and saw NOTHING but rainbows. Does higher lumens create more rainbows for DLP? And with the advances in LCOS, do the newer SONY or JVC LCOS models costing @8K stand up to the great pic of the old Marantz DLP?
