I have another couple questions, this time regarding the correct setup for HDMI input.
I am unsure what is the ideal HDMI input setting. I'd like to leave it at one setting and have ALL of my common inputs look good.
Here's my conundrum... When I set my HDMI Input to enhanced, My mac and PS3 menu look perfect, but Blu Ray movies on PS3 look all washed out:
- Picture from my Mac Mini looks incredible (depth in shadows is amazing)
- Picture from PS3 Menu system is also awesome
- Picture from PS3 Blu Ray Movies is very washed out. As a movie starts, the blacks suddenly become greys.
The only way to get the picture in movies looking good is to turn brightness down - but I never seem to be able to match the quality of the Mac with brightness at 0 in enhanced mode.
Inversely, if I set my HDMI input to Normal, the Mac looks very dark and I lose shadow details, however Blu Ray movies look okay and not washed out.
Ideally I'd like everything looking as nice as the Mac does with HDMI set to enhanced.

Either setting should give similar results but only if both the source and display are set similarly (ie, typically you do not want one set to Standard and the other set to Enhanced). Having different settings account for the "blacks turning to grays". I don't know if the PS3 HDMI range can be changed nor do I know if you can change this on the Mac Mini. But I would start there.
It is possible to use the enhanced setting on the projector and use the Standard setting on your source. But in doing so you will have to change the Brightness and Contrast setting in the projector to "fix" the HDMI setting mis-match. Typically this would result in setting the projector to -6 for Brightness and +12/13 for Contrast.
If you cannot change the HDMI settings on your sources what you could do is set the projector to HDMI Enhanced and then setup two user menus: Setup one user menu using the default Contrast and Brightness settings and setup the other user menu to use -6 for Brightness and +12/13 for Contrast. In this way you can effectively use one input for both HDMI Enhanced and Standard sources simply by changing the user mode.
In any event you should also use a test disc (like the AVS 709 disc) to properly fine tune the Brightness and Contrast settings.
I agree with Geof's advice and would like to add a little more. PCs and Macs when using HDMI use the full digital range of 0 to 255, with 0 representing Black and the value of 255 representing White. However, for digital video the standard is the digital value of 16 represents Black and the value of 235 represents white.
It appears that you have your PS3 set to output via HDMI in the "RGB Full" format. However, the most accurate video quality from the PS3 can be obtained by setting it to output in "Y Pb/Cb Pr/Cr format" and you may want to also set the PS3 to turn on "super-white" mode (see the PS3 FAQ
thread under the section on "Video and Display Settings"). Alternatively you can set your PS3 to output in "RGB Limited" format which limits it output to only the range of 16 to 235.
The key for setting up the projector is to create two different "user" settings with the reference white and black levels adjusted (using the projector's contrast and brightness controls respectively) to correctly match the type of source being used (i.e., for PC levels vs. video standard levels). The projector's HDMI input mode must be set to 'enhanced' to accommodate the PC levels.
As Geof indicated, the AVS HD Calibration Disc has the test patterns to let you easily set the reference black and white levels. By keeping the projector set for 'enhanced' you will be able to see the 'blacker than black' (i.e., below level 16) and the 'whiter than white' (i.e., above 235) video levels which makes adjusting the projector easier. The AVS HD Calibration Disc (ISO file that can be burned on a DVD +/- R) is described and can be downloaded HERE
. Once downloaded you can use a commercial program such as Nero or a freeware program such as IMGBURN
, to create a playable disc by burning this ISO image file onto a blank DVD (-R, +R or RW as long as it is a disc type that is compatible with your Blu-ray player).
