I just placed an order for this device. I wonder if the community has any experience with this that they wouldn't mind sharing. Any tips/tricks? Is this any good at all?
I will be using this to calibrate my Panasonic 4000U and 58S1. I'd appreciate any heads up to make the experience less intimidating
thanks guys.
You will be very happy with the results. It does take some practise to learn all the tricks with your particular machine. Here's some general tricks:
1. The Brightness and Contrast controls can also affect the gamma curve as well as the grayscale (every projector is different). This means you will have to adjust these controls several times during the process and their best settings may not be the "best" according to the simple white/black adjustment screens.
2. Turn all the fancy controls like the iris and dynamic gamma off or calibration will be a lot harder. Once you have the grayscale set, and the gamma curve is smooth, then you can turn the fancy stuff on, and see what affect it has.
3. Adjust gray scale by moving all the colors 1/2 their distance ie: if it says red is 110% and blue and green are 100% then put red down 5% and b/g up 5%.
4. Start by finding what color is clipping at the 100% end and tune the other colors to match it. The Contrast control affects this, so you need to adjust it as well. At the other end, Brightness affects the color balance as well.
5. A movie like Dark Knight, can really show defects in your black levels, so once you have a good approximate grayscale, turn on DK and see how the details look in the dark scenes. I found my Brightness setting was not as good as I imagined and I had to adjust it and then check the grayscale again. Colors in DK dark scenes are not reliable, sometimes the colors seem off but its the lighting in the movie that is affecting it; so don't try adjusting colors by looks - at least not with that movie.
6. 0%, 10% and 20% are not as accurate color wise as the other %'s, due to the low light level. Red is the color most easily seen if you are off, blue is the least obvious (ie: its not as big a deal if you don't hit the right blue level) and green controls most the brightness level. Take a look at the B&W ramp and you can easily see if you have too much red at the lower end. It might be possible to nudge it down a notch or two, but you can't rely on your eye to adjust color far from the meter values.
