What is the problem with the grey scale?
Out of the box, my (all) BenQ is running about 8300K, not 6500K. Red Green and Blue is not even aligned. Some Sony's run as high as 9300K. This means BLUE greys in video not grey greys in video and WILL affect every ithger colour we see.
The display has to be fed with various values of Y with the Pr and Pb @ 0 (digital level 128). Then you need to get the grey scale to appear grey against a grey scale card illuminated with light of D6500.
Does that card tool actually exist? It may be useful on a CRT but not for a projector as you do not want to be adding light into the room.
The other way to do this is to use an Radiance meter (measures the radiated power from the screen and not the light from the screen) and measure each primary in turn. Each value should be identical. Very few people can use this method because of the cost of this piece of measuring equipment.
Is that the peice of gear with the "CYBERDYNE" logo on it?
The coloured filters I was referring to are the ones provided with the disc.
Yes, and they are the ones said to be not accurate.
