Hi,
I thought I would start one of these up as oddly there doesn't seem to be one on here. There is various good info dotted around the forum but thought it would be a good idea to try to keep it in one place going forward.
I have a few queries to start with from reading some other threads.
a) I have been interested in some owners' comments using filters with these models, specifically an ND2.
My projector is located in my main living room so is far from light controlled, I have blackouts on the curtains but there is still a good bit of light leakage during the day, however, when it gets dark it's obviously not a problem and all my AV kit is housed outside the room so there is no light spill from any LED's etc.
I am interested in what would happen if I applied an ND2 filter. From what I have read it seems to increase black levels but reduces the brightness (forgive my ignorance, but does the black level reduce because the overall brightness is reduced or is this a side effect of something else the filter is doing?).
I had a go at calibrating the PJ a few weeks ago with an eye one probe and HFCR and from memory was getting an Ftl reading of around 12 (I currently have about 900ish hours on the lamp).
Am I correct in assuming that an ND2 filter would reduce this brightness considerably? If so, am I also correct thinking that this would still be acceptable during night/dark conditions but may be problematic during day viewings?
b) Colour setting: I am interested at what colour setting people are running their units at. When I did the initial calibration I was mostly concentrating on contrast/brightness and grey scale and didn't do the red as a percentage of 100% IRE measurement.
c) Gamma: Also any owners who have calibrated your units, how did your gamma look and on what setting. I found that my reading was low (can't remember exactly but around 1.7 I think) and wasn't anything like a straight curve - will adding an ND2 filter have an effect/improve the gamma level?
