Had a background reddish tinge that just wouldn't go away, despite using the old Pixel Washes, tweaking and calibrating. Of course, the tinge threw off my calibrations. After using the Pixel Protector's new calibration feature, I've ended up with the best calibration ever from all the various calibration DVDs I've tried over the last several years. (inc WOW, S&M, AVS, etc.) After the initial calibration, it's off to letting the 3 washes run on my set for several hours, then back and do a final re-tweaking. At the end of the preliminary tweaking, I ended up with the best PQ, so far, that this set has seen! Should be even better after the re-tweaking. Strongly suggest getting this Blu-ray, and try for yourself!
Now I wasn't imagining the reddish tinge, and I'm not imagining the the Pure White screen I have now! I'm also not imagining the Best PQ this set has ever seen since I started tweaking it several years ago!
Will do the final re-tweaking tonight and see if the values have changed since the reddish twinge is now gone.
This is unsupportable baloney. There is NOTHING a disc can do to remove a calibration problem.
Let's say YOUR TV has a reddish tint to the background. And Jim's TV has a greenish tint to the background, and Steve's TV has a blue-ish tint to the background... but they are all the same brand and model. How would the disc know that your TV needed more green and blue or less red in the background and fix that problem with your TV while Jim's TV needs more red and blue or less green to fix his problem and Steve's TV needs more red and green or less blue to fix HIS problem? It's just freakin' impossible.
The TV doesn't KNOW it has too much red in the background (whatever that means), the disc doesn't KNOW the TV has too much red in the background. How can the problem be "fixed" by the disc? It CAN'T be fixed by the disc. The data the TV receives has to be changed for the images to change. The disc isn't going to change the data the TV receives. And the disc can't change how the TV responds to the data.
On top of all that... plasma is a digital display technology where the pixels can only be on or off... there is nothing in between. To make intermediate shades of color or gray, the pixels have to turn on and off multiple times during each frame. But you can't turn all the "20% gray" pixels on and off at the same times or the images are going to be a mess, you have to vary which pixels are on and off randomly so you don't see anything odd at your viewing seat. LCD technology takes a digital input signal and converts it to a stepped analog voltage that controls how transparent or how opaque each individual pixel is based on the bits received for that individual pixel and the look-up table inside the TV. If a green pixel has the digital value of 100, the TV goes to the lookup table to see what voltage level should be applied to that pixel. The lookup table voltage values are controlled by the TV's controls, not by video content.
So... how could two such disparate video technologies each have their respective images "improved" by ANY sort of disc that would apply any sequence of patterns?
I'm afraid, without measurements, your observations are meaningless. One of the ways human vision is fooled is by putting shades of white next to each other on the screen... for example. If you put a white that is much too blue next to a white that is "perfect" (d65), the "perfect" white will appear too yellow while the white that is too blue will look white. You can't stop this from happening. Even if you KNOW the part of the screen that looks white is really too blue, your eye-brain will still latch-on to that being an accurate white while the accurate white is made to look inaccurate. This is undeniable -- for humans with nominally "normal" vision this is ALWAYS what happens. And you can get other "tint" discrepancies also. You cannot trust your eyes and you MUST use instrumentation to confirm observations.
Panels also may not look the same when they have been on for 30 minutes vs being on for 1 day or longer. So your observation points must also be identically timed. If your initial observation was made when the TV had been on for 30 minutes after being off overnight, when you make the new observations (which had better have measurements being taken), the TV should also be on for 30 minutes after having been turned off overnight.
You can't just do a lot of random baloney and say there's a difference.
A lot of people have paid money for cow magnets, intake vortex generators, and all manner of other crap that claims to improve horsepower or mileage or both and not ONE of them has EVER improved the mileage/performance of any vehicle yet there are endless testimonials from the deluded.
If science is too hard to understand... try pseudo-science (like these pattern discs). No training or education required - everybody's an expert.
