I have my D2 set to extended RGB for the PS3, with PS3 hdmi set to full RGB, is this correct?
See the "Video Calibration for non-ISF Techs" post found in the collection of links in the first post in this thread.
First of all, Extended RGB is almost always the wrong choice if you have the option of Studio RGB, or even better YCbCr. See the posts in the "Data Format" section of the collected links for details, but the simple reason is that use of Extended RGB means you discard Blacker than Black and Peak White data and "stretch" the number of steps from Black to Reference White (which likely introduces some banding).
For connection to the D2, the PS3 should be set to send 1080p/24 (for normal Blu-Ray movie playback -- also enable 1080i for "live video" Blu-Ray discs, 720p for some games, and 480p -- no upscaling -- if you intend to play standard DVDs as well), using YCbCr output and with SuperWhite turned on. The Extended/Limited RGB setting should be left at its default, Limited setting, but it doesn't really make any difference so long as you are using YCbCr output from the PS3. The Extended/Limited setting only affects RGB output. I believe some games may force the PS3 to send RGB so that's why you should confirm the Limited setting. Meanwhile, in the Video Source Adjust / Picture / Input Color space menu for that input in the D2 (under the "7" key), confirm that Auto YCbCr and Studio RGB are both checked.
Calibrating a modern TV -- as done by a professional calibration specialist (i.e., an ISF technician) -- involves several things a user would not normally be able to do, or do well, beyond the setting of the basic video levels (e.g., Brightness, Contrast, Color, Tint, and Sharpness). In particular, the ISF tech will attempt to go into hidden service menus in the TV to fine tune the gray scale ramps and color temperature of the display -- Gamma correction and such. To do that, he will use a signal generator that sends a known signal to the display, and he will have to adjust the basic levels as well as a preliminary step of this. But the MAIN thing you are gaining from this effort is the adjustments he makes in the service menus to refine the internal factory settings of the display. And when done correctly this is a big win.
The video the D2 outputs, as exemplified by its internally generated test patterns, is close enough to a reference video signal (if not identical) that the calibration the ISF tech comes up with should be just right for use with the D2 as well. BUT, if the tech was forced to make some compromises in his setup of the display -- as is far too common given the limited adjustment controls in many displays -- the basic level settings he leaves in the display may not be quite perfect for use with the D2.
Ideally, having adjusted the display using his signal generator, he should then REFINE those adjustments (again in the service menus as necessary) to precisely match the video the D2 puts out using the D2's internally generated test patterns. It may turn out that only modest tweaks to the display's basic video levels will suffice or he may need to revise his entire "compromise" combo of settings between the basic levels and the service menu.
The D2 also provides additional control over the Gamma correction built into its video output. The tech may be able to make good use of that to get around limited controls in the display itself, and to come up with a video solution which is more perfect and less of a compromise. Again, this sort of thing is BEST done inside the display, so that's where he should start. But the output adjustments in the D2 (Video Source Adjust / Output / Gamma for EACH input -- as extended by the Live Video Settings Editor application) may provide just the extra control he needs to get around some thorny problems in the display.
If the tech doesn't want to do that, for whatever reason, then *YOU* need to adjust the basic levels of the display to match the output of the D2. And with a well calibrated display the necessary tweaks should be minor. It is unlikely you will go into the service menus yourself, but you will likely be able to refine the display's settings all you need simply by doing user level adjustments of its basic video levels.
So whether or not you do this sort of full scale adjustment of the factory settings of the display -- including service menu adjustments -- it is still fundamental that the initial step in setting up the D2 is to refine the basic video level settings of the display to best reproduce the test patterns internally generated in the D2.
And all of that is independent of any video input sources connected to your D2.
Once that is done, you adjust independently for your video input sources using the input adjustments on the D2. The display's setup remains unchanged during this as it is the D2's job to convert any input video to the same video output (as shown by the D2's internal video test patterns) that you've already used to set up your display.
