Calibration 101, how to start to adjust grayscale for luminance and RGB balance.
First use the settings I show from this post. https://www.avsforum.com/forum/40-ole...l#post41046818
Also you may want to adjust Blue high +2 and set your Gamma at 2.4 in your EF9500.
Now look at the screen shot in this post (Below).
Look at the Y value (not small y), Target (Y) and what my meter read (Y) for each 5% increments.
Example. IRE 20, the actual meter reading is 2.9985 (actual is a little high so you may want to lower luminance) target is 2.7897. Also look at the chart you will see the RGB lines are above the base 0 line. So what you would want to do to get a better light output (luminance) for 20IRE is to lower Green by -1, Red and Blue by -2, IRE25 about the same, IRE30 Green -2, Blue and Red -2. And so on up to and including about IRE50.
When making any adjustments to RGB (H/L, 20pt, grayscale) use a corresponding color patch to make sure you don't see any other tint than gray. Ted's calibration disc or AVS709 disc for 20 point grayscale patches and a grayscale ramp.
When making adjustments it is probably a good idea not to make any large adjustments, use the KISS method.
