So just change it from +2 to 0.

Lists #6 and #7 are best for video sources other (OTHER) than those like (LIKE) my cable TV service. OTHER includes DVD/antenna/cable/satellite/PC/games/etc., and you can use any of Quattron's HDMI/antenna/component/composite inputs. List #6 has better saturation of certain shades of yellow, orange, green, and cyan, and better black level and viewing angle, but #7 has better dark scenes. The undersaturated colors of List #7 are very noticeable in test patterns, but hardly ever in TV shows. List #7 seems better than #6.
Lists #2, #5, and #8 are best for LIKE video sources. List #5 has about a 75% net reduction of color inaccuracies over List #2, with better red, skin tones, yellow, blue, magenta, bright scenes, and definition of highly saturated colors. List #2 has better orange, green, purple, black level, and viewing angle. List #8 is about as good as List #5, and since it uses USER rather than GAME mode, you can easily switch to it if you want to keep GAME reserved for DVD/antenna/etc. settings.
All lists may only work for the U.S. model. None seems to have much if any bluish cast. Picture quality is mostly very good, sometimes excellent, but occasionally fair, especially for scenes that have a lot of specific inaccurate shades of color, dark colors, highly saturated colors, or pallid, washed-out colors. If Lists #1-7 don't look similar, or the colors are wrong, then you might have a different cable service, a different Quattron model, or different firmware installed.
Lists #3 and #4 have superior definition in areas of high color saturation, but #4 has mediocre color accuracy. Trying to improve definition by reducing Contrast and increasing Backlight makes all colors "smoky" and hurts viewing angle and black level. Trying to improve brightness by increasing Color Temp. for Blue makes all colors bluish, which can only be partially corrected with CMS-Hue.
It's been about a year since I posted my first color settings here for the U.S. model LC-40LE810UN (the 810) Sharp Quattron. I thought it would be impossible to improve color accuracy and definition this much due to this model's firmware constraints. I still doubt this model's color inaccuracies can be totally solved without new firmware. Presumably a firmware error causes a "spectrum compression problem," as I previously explained, which compresses and expands all the RYGCBM segments of the spectrum. Another problem is Brightness level causes a "hazy" reduction of viewing angle in certain rare scenes. I think Sharp could provide new firmware to more thoroughly solve these problems. One problem that I doubt could be improved is seemingly a bit greater loss of color with increasing viewing angle than for other LCD technology, and is probably due to Quattron's elongated RYGB pixels. If you're used to watching LCD sets, then it's usually only bothersome in certain rare scenes full of pallid, washed-out colors (certain old movies, etc.).
I figured out that Quattron's firmware distorts colors in my cable TV signal in a different, specific way than in other video sources. Not only that, but even the cable company itself distorts some colors in the original broadcast signal, like reds and skin tones. These inaccuracies are in addition to the Quattron firmware's spectrum compression inaccuracies.
This Quattron model has a brightness glitch. I was changing settings in MOVIE and DYNAMIC and it wasn't working out, but a little while later, all modes became blindingly bright. To get normal brightness in GAME I had to change Backlight from -7 to -12. This is the same problem I was having a year ago. So then I tried setting Backlight levels in MOVIE and DYNAMIC to -12, where I had left them about a year ago. This didn't fix it, so I turned off the TV, and when I turned it back on, brightness in all modes was mysteriously restored to normal. IMPORTANT: Backlight must be set to -12 in both MOVIE and DYNAMIC modes for correct brightness with Lists #1-8. If not already set to -12, then you must set them both to -12, turn off the TV, wait several seconds, then turn on the TV.
Since my last post in May, I have not had any more problems with clouding, or with occasional, sudden oversaturation of colors after switching INPUTs or AV MODEs, which was correctable by switching around a few more times. I think these problems may have been stopped just by using these lists. Changing the settings of STANDARD mode to List #4 may have been the key to stopping these problems, since none has recurred after that.
I think all new Sharp TVs are Quattrons, but I don't know if the latest models have corrected firmware.
