I'm opening this topic for Hardware Pattern Generators Users, like Lumagen/Accupel/Quantum Data/VideoForge, that are curious to see what's the difference of the patterns that are generated from their External Hardware Generators vs. their Actual Blu-Ray Player using a Pattern Disk.
For anyone who want to test this to his system, please check the following things to help all data's that will be collected to be valid & uniform:
1) Be sure that the Color Space Output is the same to both Blu-Ray Player / External Pattern Generator.
2) Use the Same Settings / Same HDMI Input of your Display / Projector. You don't need to have this input you will measure calibrated.
3) Use Only Full Field Patterns without Labels (including Plasma users also) Because Window Patterns will not match exactly at their size between disks/pattern generators. (Plasma Displays are not reallt recommended for this test.)
4) Disable all Display's Enhancements before measuring.
5) Reset to Unity if you are using a Lumagen/eeColor in Chain. Disable Darbee Processing also.
6) Use only unprofilled colorimeter, not a spectro, we don't care about the dE your display have, we care only with the dE Differencies that the 2 patterns sources will have.
7) Run a 21-Step Grayscale, 4-Step Luminance & 4-Step Saturation with ChromaPure or 5/10-Step Saturation/Luninance with CalMAN.
8) Use only Pattern Disks that are it's encoding is based to Each Software Engine Targets. For Example Don't use AVSHD Disk Pattern for this Test, not because the disk has any problem, it's patterns are 100% accurate, but they have as slight difference between the targets the software solutions are generating with external pattern generators.
Ofcourse the disk can be used for any Calibrations using ChromaPure or CalMAN but not be used for this test because the AVSHD Patterns RGB Triplets are +1 -1 Level different from each software calculation engine. Color Gamut 100% Saturation with 75%/100% Can be used becasue they have the same RGB Triplet Levels. 4-Saturation Patterns have bigger differencies and it's not recommended for this test.
A Quick Example of Grayscale Patches of AVSHD Disk vs. CalMAN/ChromaPure Targets is here:
AGAIN: This difference in Grayscale Levels will show only differencies when you will compare a Pattern Generator with a Disk Pattern Source. No difference if you are using the AVSHD Disk for Display Calibrations.
AVSHD Disk has been tested with Waveform Monitors or by extracting the Original Pattern Files form it's Video Files and has none problem to any pattern. 100% Accurate.
If the other disk creators are reading this, please confirm which targets you used at your disks, to help us out selecting the correct disk for each Measuring Software.
Mid-Next Months I will release my LightSpace Calibration Disk that will have Patterns Based to ChromaPure + CalMAN Calculation Engines, but it will have only Large Window 11,11% ''Lumagen Size'' Patterns without Labels, so it will be usefull only for Lumagen Radiance Comparison.
The User Posted Test Results will help by creating a Database of Blu-Ray Players with their difference with various external pattern generator, by helping users to decide if they will be use a Disk or an Enternal Pattern Generatar for it's future calibrations.
