Maybe I'm obessing over it for some reason, but I notice that the border on the TV is a shiny black and the letterboxing surely does not match that blackness. One of those things that is a little distracting when watching a letterboxed movie
I'm just acting crazy...
Your not acting crazy. It's why everyone is in the threads.
Your getting milky or greyish blacks because your Brightness is high and Contrast is low. You have narrowed the ratio. your scale or range is now limited. You are not reaching 100% black when the signal is 100% black. This also washes colors that rely on a wider range or Contrast of Black 100% to White 100%. The higher the contrast ratio (without overdriving it) the better the color reproduction and overall PQ.
A good readup on this is here...
Read page 5 http://www.calibrate.tv/docs/GetGrayCalDiscReadme.zip
I have the exact same TV and I have 3 calibration products now and will be getting a light meter to measure my WHITE FL output.
Try this setting and tell me what you think...
This is my setup.
TH42PZ85u TV = Cinema Mode. Warm.
Source (DVD or BD player) set to output 7.5 IRE aka Darkness mode = LIGHT and not Dark which is usually the default mode on players nowadays. Only set to Dark (0 IRE) if over Component.
Connection type HDMI. Direct to TV. No Upscaler device in between like an HDMI switcher.
92 Contrast (calibrated with Getgray and DVE. Slowly increasing contrast with the last click where the 100% white bar (3 dots aka 235 digital White) matched the 5% over white)
56 Brightness (All three products arrived at this. Digital noise/speckles in background vanished right at 56 along with the 2 below black bars leaving just the 1% bar barely visable)
44 Color (All primaries are bang on with my Lee Filters using the DVE Color Pattern tests)
0 Tint (lowering this to perfect blue filter tint threw red and green primaries out. Left it alone at 0 and they are perfect. tint is almost perfect anyway)
50 Sharpness (When viewing through HDMI, no results on ANY sharpness pattern. Only on my digital TV signal)
Everything else set to off.
This setting makes the Demo material on DVE HD Basics look incredible and the movies I have played through are crisp, natural and bright but not overpowering and the depth of field is remarkable.
Caviat - Not all TV's calibrate the same way. My Contrast was arrived at using a different set of rules than those used on DVE. I used Getgray's concept of 100% White is 100% and should look the exact same as 5% above white as Digital material is encoded with a 16 bit black to 235 bit white scale type process and the viewer is not supposed to see items on the screen below black or above White. DVE instructions had me sitting in the 70 to 80 zone. I am still reading up on light output but 35 FL's seems to be something I am supposed to be achieving from absolute white. While this could all boil down to preference, I have a few photobugs (one of them is an AV tech kinda guy with some video production experience and schooling) telling me that the description in Getgrays usage of Reverse Greyscale Ramps is Digital signal/fixed pixel enviroment oriented and the directions on DVE for using that patter are more of a CRT based description but they can't be sure. These opinions are from NTSC land and PAL land may be a very different place. I know nothing of that.
My only personal experience beyond owning a paid of eyes for 40 years is that I am an IT guy that used to calibrate computer monitors for photoshop using color chips and special ambiant lights.
Sorry. New hobby. I get a little obsessed.
These settings look like ass on the other source I have which is Digital Cable. Everything ends up yellowish or dingy. Sources differ I guess. I use Standard which defaults to cool and am still experiementing with the rest of the settings as every channel acts different... because they are.
