I have a Sony D-50 with a Denon D 2800 in progressive mode and want to gray-scale calibrate the system.
I bought an VA-1 colorimeter from AV-Science to do the job.
The contrast from the projector is set to 77 and the brightness to 37 (set with AVIA).
The VA-1 read 19.6 fL in the 100IRE windows pattern.
I think thats too much for the Sony. If I reduce the contrast until the VA-1 reads 12.8 fL the picture is too dim. I think the VA-1 shows the wrong Y values.
What can I do to calc the correct values from the VA-1 readings.
Should I use the 20 or 30 IRE window pattern for the bias and should I use the 80 or 100 IRE pattern for the gain calibration.
The Sony manual tells not to touch the blue gain.
Should I use the blue and red gain or the blue and green gain.
Do I need the G2 control?
An excel file with the VA-1 readings is attached.
Many questions ,any hints ?
