This is how the projector is supposed to work. I recommend setting the projector up with the video going directly to the projector. Don't do any video processing until the set-up is right then do the processing.
Thanks again Scott. That is the one weird thing tho with these Marquee's raising contrast affects blacks more than I like, for every two numeric values of contrast I have to lower Brightness one .
Also with these long bows the Calibration is a bitch!1 I do have a radiance in the chain but have it set to default and use its reference patterns for greyscale not using any of its
processing Red drive and blue drive really alter the low end quite a bit. A few clicks of red drive on 80 IRE makes a noticeable change in 30 ire . I wonder if
it the peking circuit of the vims or maybe the LongBow Software works the Color balance controls differently. I did remove the stock 8 inch tubes with new 9 inch tubes.
But I have calibrated other Marquee's and have not had the same behavior . I remember when I first got these instead of a blue Bump in the middle I had a blue dip .
I know I have gotten a nice flat calibration on my old 8000 with no processor, just a slight bump in blue on the mids.
But i will try a calibration of 20 and 80 using only my Oppo. I will have to set up a new memory for it. then hook up the radiance and the blend scaler to see how much they alter the oppo only calibration.
