(page 7 of this thread) It seems like the 5020 does have some clipping issues and adjusting the contrast down a few notches on the OPPO does produce much cleaner contrast ramps and also eliminates the color clipping problems with the color clipping patterns. I would not have thought a -2 notch contrast adjustment on the OPPO would produce such significant changes on all of those patterns, while doing the same on the Pioneer had little impact. I will watch a movie tonight to see if i notice any real change. I would think it is going to be subtle as the color bars were spot on in movie mode before and after adjusting the OPPO.
My PIO 5020 is obviously the same way with the Oppo. I found that reducing the players contrast -2 made all the relative test patterns look nearly perfect; otherwise the clipping was very obvious. Lowering the displays contrast less than 40 showed no discernible difference. Interestingly, putting the contrast past 42 shows no visible difference in light output. 42 looks like 50, but at 42 the clipping definitely gets worse.
In the clipping test with the colored boxes, it's pretty bad. I can't barely make out anything, but changing the oppo to -1 or -2 makes it look just right.
I also found for brightness, the best setting was negative -1 on the display, plus 1 on the player. Moving the display up 1 to zero and keeping the Oppo at zero didn't look nearly as good on the test patterns. Using the pluge low pattern -1 is clearly the right setting, but when you look at pluge high or the contrast test my -1 setting makes it almost impossible to see boxes 18,19, and even 20. If I bump the oppo plus 1 for brightness the test patterns look great.
That said, I am not comfortable changing the player settings, even with it set to 36 bit color. I just don't like the idea of "altering" the source and have decided to work within the limitations of my display. I will have to do some more comparisons to be sure, but my inclination is that the image is more appealing to me by NOT adjusting the controls in the oppo, and it may even be more accurate within the limitations of the display.
Sharpness is always a tough one to set for me. I just can't ever seem to tell when the artificating starts. It's obvious when it's there(ie. at zero), but did it start at -1, -8, -15? I can't tell. I get right up on the screen, use the "before" and "after" feature on the display, and I just can't tell. Most people's pro calibration reports put it around -12 to -8, so I go with something in there, but I sure wish I could set it better.
For color, I had originally used a colorimeter when I first got the display and found 0 or +1 resulted in the lowest average delta Es. I tried to use the color filters and they did nothing to deter me from that conclusion.
Tint's always been at zero. With my objective measurements and slightly more subjective color filter, it seems accurate.
Anyway, great test disk. I love the layout of it and it's ease of use.
