I played with the HD709 disc again today. I had some non optimal settings on the PS3 that was causing clipping of white and black
Two settings that are definite for me are
Brightness 50
Contrast 74
I like to adjust the back-light based on the room so I'll have two modes that are the same accept for backlight.
My Disney WOW disc should be here Monday. For kicks I made a blue filter with water and blue food coloring. I adjusted tint and color based on this. I'll see how close it compares to an actual blue filter that comes with my disk.
My liquid blue filter resulted in:
color 51
tint -1
RG 104
GG 124
BG 116
RO 128
GO 128
BO 128
The sharpness pattern allowed me to go up to 3 without artifact. I seem to like the backlight around 60.
I've noticed flashlighting has started to develop in the corners the more I use the set. On the 100% white pattern I can see some non uniformity on the screen. There is a 5" band just to the left of center that runs from almost top to bottom. There also appears to be a region in the middle of the screen that has a slightly different color than the rest of the panel. It's barely noticeable on the white screen. Not enough to take it back to Costco, but i wanted to let everyone know that my 3rd set is not perfect (serial 50).
I'm quoting myself so everyone can see the before and after. The above is with the HD709 and a blue filter made with water and blue food color. Below is with the Disney WOW disk.
I'm a bit disappointed by the fact that unless you have a meter to measure gray value and color there is only so much that you can do as far as "knowing" you have it right.
Mainly: brightness, contrast, color, and tint.
The WOW disc does offer some nice still images to dial in the RGB gain to your liking. Messing with the RGB offsets proved to be pointless. It messed up my blacklevel settings. If you dial down the RGB offset, you have to increase the brightness to get proper black level back. I thought I was on to something when I dialed in a 2.2 gamma using the disk with the RGB offset. The I found out i was really just making everything darker. Too dark
Nice tutorials, and disney movie clips that look fantastic.
There are two avenues to take with contrast. Allow nothing to show above true white, or follow the HD709 and allow visibility up to 244. The following settings don't show contrast above true white. If I allow the 244 whites to show, then the contrast has to be dialed back 3 points. I'll list my bright room and night settings. They aren't really different. I think LED is so damn bright, that you don't really suffer during the day.
Backlight: 58 night 35
Brightness: 51 ; 50
Contrast: 79 ; 80
Color: 51 ; 51
Tint: -1 ; -1
Sharpness: 3 ; 3 (1 shows no artifact on the patterns, 2 showed artifact on a fisheye pattern, 3 showed artifact on fisheye pattern, oddly 5 showed less artifact than a setting of 4 on the fisheye pattern, but both showed artifact on main sharpness pattern.
RG: 106
GG: 110
BG: 120
RO: 128
GO: 128
BO: 128
All enhancements are set to off
