My meter did some work with the Cool, Med and Warm settings that I thought I would share.
To start things off, I put up a 50% white screen an went to the service menu with the XF set on Med. There I left Red drive at 60H and adjusted Blue Drive and Green drive until my meter reported a 6500 temp. At 6500 with the panel set on Med, my drives were:
You will note the big cuts needed to the drives vs adjesting for 6500 in warm mode. But what the heck, they are just numbers.
Here is what the temp chart looks like with the new drives at the Med setting.
Here is the temp chart at the Warm setting the temp is centered around 5000 and this curve is the flatest I have seen.
Here is the Cool setting temp chart, Note that the lower temps are so high they are off the chart. The higher gray percents are centered about 9000.
So we see that with Med adjusted to 6500, Cool is about 9000 and Warn is about 5000.
Lets look at the individual colors now.
Here are the individual colors in Med, looks ok, the Red, Blue and Green luminances are about equal from 50% up.
This is the color chart for the Warm setting. Here Red has a 120% higher luminance than Green and Blue runs about 80% of Green. This spread in what lowers the temp to 5000.
For the Cool setting, Blue has a 130% higher luminance than Green and Red is 80% of Green. Kind of the inverse of the Warm setting.
So we can see that although the drive settings in the service menu do not change, the display is using them as a starting point and will add or subtract from them to set the actual drives in Cool, Med, and Warm modes.
I will try these Med 6500 settings for a while, the 30% and 40% measurements are a bit closer to 6500.
