RS2/ PRO-FPJ1 Owners: Setup Discussion Thread - Page 101

What bluray offers such control?!! None!

He has tweaked his gray scale and for that RS2/clone has enough control for that.

To get perfect gamut with this PJ you need and external VP, also many of the newer high end blu-ray players from Denon and Pioneer give you greater color control lattitude the this PJ. Now as far as greyscale my RS2 was as good as I could ever want out of the box.

FPJ1 doesn't has NO control over color decoder why do keep saying it has limited control.
Which pioneer bluray player offers CMS? Can you elaborate?
No RS2/fpj1 Out Of Box has good grayscale. I am sure it was good enough for you but off by a good margin.

Thanks Wayne,
How does your gamma look?

Projector is 18.5 feet from the screen and the sitting position is about 13 feet.
I would like to get a screen that is at least 120" diagonal.
Projector is the FPJ1.

Thanks for the help.

I've found that the best way to go about this is to work on the color that's out the farthest first. In my case, blue was the worst so I used that control to go into the minus area I think around 85 or so. Then I chose to adjust green. This is the first projector that I've touched green. With my BenQ W5000 it wasn't necessary and it also didn't have direct 0 to 100 IRE adjustments either, only Gains and Cuts.

However, even though the Guide states not to fool around with green, I found that with this projector I had to in order to get anywhere close to D65. After green was tweaked I lastly tuned in the red. One way you'll know if you're anywhere close to accurate with the CT/Offset results is when you go to the Gamma WRGB controls and start working in there. If you find that you have to move anything to where it's drastically removed from the stock number then you probably need to go back and revisit your earlier work with CT/Offset.

After many tries, I found out that the Gamma controls are meant for small fine tuning only. If you start to move any of the controls in Gamma up or down and don't see the color bar in the software move in response after a few seconds then try one of the other colors. If there's very little movement unless you change the numbers in a huge way, then you're going to be in for a very long and frustrating session.

I'm not sure if there are different ways to the same result or not. With my unit, it seems that unless I have the CT/Offset red near zero, green around 40 below it and blue about 40 below green, I don't get anywhere with my calibrating efforts.

One thing that is very frustrating is the fact that you can't save different Gamma settings for different sources the way you can save Memory1 for HTPC or Memory 2 for BD for instance. Because of this I leave the final tweaked Gamma settings alone once I have them set for one of my sources and then only do CT with the other Memory for the other source and get it as close as possible. It seems to not end up as good as the best tweaks for source number one but it sure beats going in to the Gamma controls and re-setting all of those numbers just for watching one movie with a different source.

By the way, I never touch the Gamma W control because I don't really know what to do with it.

The RS2 was sent back and after they put 20 hours on the projector, they came back with "it can be corrected in custom." The final result is I will have to significantly tweak the custom gamma to correct the grayscale uniformity while adjusting color temp to achieve D65.

It is apparent that with a lot of work, the grayscale and gamma can be adjusted to track very well from setting up a custom gamma memory. This requires adjustments way beyond those I have initially done in the RS2, including my own. It is apparent that the custom gamma creates its own LUT.

When you send a unit in need to keep fingers crossed.
