HOW TO FIX THE 1:1 PIXEL INTEGRITY AND UNIFORMITY ISSUE:
With the projector's factory default settings, which is how it is delivered to you, the presets are set to provide what SONY has chosen to provide out-of-the-box. Whilst this clearly provides a great looking image, there exists the potential for uniformity issues.
This is in part (but not completely) caused by the 1:1 pixel mapping integrity of the projector being compromised with these particular settings; the result of which is that the projector is not able to fully resolve at the single pixel level.
There also exists potential uniformity issues in addition to this; and it should be noted that this phenomenon is seemingly worse with the SONY 885/760ES as compared with some of the other models of SONY projectors. With respect to the other models of SONY projectors SONY claims that the issue does not affect actual video content, only test patterns; however, with respect to the SONY 885/760ES it most certainly does affect actual video content, and see below for an example of this.
With these settings this can induce some undesirable video artifacts including moire, chroma shifting, splodges, and a general uniformity issue, which are intermittently slightly visible in both test patterns and video content.
There is no fault with the projector itself. This is simply being caused by the particular choice of settings that have been selected by SONY for the out-of-the-box settings. The good news is that if you find this to be an issue it is easily fixed via simply changing of some of the settings.
If you or your AV dealer wish to see what's what in this regard then I recommend checking out the Single Pixel Resolution Test Patterns found within MISC TEST PATTERNS MENU #2 on the excellent DVS HDR10 Test Patterns Blu-Ray Disc / Digital Download: http://diversifiedvideosolutions.com/dvs_products.html
THIS is an example of the issue, which is the MIXED PIXEL TEST PATTERN off the DVS HDR10 Test Patterns Disc as displayed via the SONY 760/885ES projector with its factory out-of-the-box settings:
Well have your AV dealer carry out the following steps and that image will transform into looking something like THIS:
The fix involves entering the Service Menu for the projector.
I can't tell you how to enter the Service Menu because this is something that only AV dealers should be doing
It is very important to note that any owner/customer who enters the Service Menu themselves risks invalidating their warranty so you absolutely must not do so
However, I can and will now provide the details with respect to the steps that need to be taken such that you can provide this to your AV dealer and have them carry out the modifications and hence the fix for you
Here we go:
This is what your AV Dealer needs to do with respect to your projector for you:
1. In the projector's settings menu ensure that PANEL ALIGNMENT is set to 'PRESET' and not 'ADJUST' (this is the factory default setting so it should be already set to this, but make sure that it is)
2. Enter the Projector's SERVICE MENU
3. Select 'DISPLAY ENGINE' and press ENTER
4. Move down to Number 21 "AREG/SERVICE". Then press the LEFT ARROW key on the remote to change the setting from '1' to '0'. This turns off the automatic zone pixel alignment.
5. Display a single pixel test pattern (such as those found on the DVS HDR10 Test Pattern Blu-Ray / Download). If you see uniformity issues and/or video artifacts including chroma-shifted moire, , then go to service menu Number 2 "DE/UF SW". Then press the LEFT ARROW key on the remote to change the setting from '1' to '0'. This switches to a different uniformity preset. If you don’t then skip to #7
6. Display a single pixel test pattern again. If you still see uniformity issues and/or video artifacts including chroma-shifted moire, then go to service menu Number 15 "DE/WB SW". Then press the LEFT ARROW key on the remote to change the setting from '1' to '0'. This switches to a different default white balance setting. If you don’t then skip to #7
7. Move up to 6, 7, 8, and 9 and adjust these if necessary for optimal RGB pixel convergence.
8. Go back to the first SERVICE MENU menu and select "SAVE TO MEMORY"
9. Recalibrate the projector to D65 white point.
Here's just one of numerous examples of the uniformity issues manifesting in actual video content:
