To use the Proffesional ''defacto'' Cube Size of 17-Point Cube Profiling (4.913 Color Points), LightSpace has internal pattern generator using your HDMI Output of your Notebook (with proper setup). You can set the window size to whatever pixel Width+Height you want, and accurately center the window pattern.
The next alternative that will come soon, (available for free download), will be the Ted's LightSpace CMS Calibration BluRay-Disk
, with this disk you can able to use your actual Blu-Ray Player as a Pattern Source, with an automated 17-Point Cube Profiling of 4913 Color Points without user prompt during the whole process, exept the initial sync, you can see details about that to my link above.
This is the way I'm profing my KURO for the last 9 months already without any problem.
Calibrating like this, using your bluray player, you are profiling the whole video signal chain of your system, with more accurate resutls from any Pattern Generator of any Price, because you fixing inaccurancies of your player with that way, something that a Patttern Generator can't see.
Using my disk you will need only: LightSpace HC Light Software, eeColor, id3 oem.
This minimizes a lot the total cost for Really Profesional Results to your own Home Cinema System, with exact the same LUT accurancy as All These Studios/Colorists/Color Related Pro's
are already using for almost from 2008 (When LightSpace Released), since LightSpace is used @ Professional Industry already all these years only for Large 3D Cube Profilings.
Here at Consumer World, 5-Point Cube Calibrations (125+21 Color Points with multiple meter reads per color point) introduced to us @ Summer of 2012), the Same time that LightSpace was used to calculate 4913 Color Points Profilings with only 1 meter read per color point from 2008.
Another altenative for Hardware External Pattern Generator are the Lumagen Radiance Series Processors, like Mini-3D.
