Did you find any trick to make the display to behave
So here's my trick:
In Calman, to the left of the action buttons on the bottom of the screen is the Pattern button. Click the top of the Pattern button and select the Brightness pattern from the menu so that every time you click on the center of the Pattern button, you will put up the dark Pluge pattern on the screen.
When you calibrate, start at 100% or where ever you want and take a manual reading then click the center of the Pattern button.
The result is you will have the gray scale pattern that you are working with on the screen only for the time it takes to do a reading. Then the dark Pluge pattern will be up while you are seeing the result and figuring out what to adjust.
You then keep repeating the process. What this does is leaves the gray scale pattern up for only the short period of time that's needed for the reading then returns the screen to a dark, "idle" state.
You will see that you only need a couple of scans and the 21 point will line right up and you can do an automatic scan at the end to verify your results.
This works really well when you are calibrating ISF Bright or HDR and have everything set to display the brightest picture. This is not needed as much when calibrating ISF Dark or any dark room modes because the screen is at a much lower luminance level.
In talking to some folks, it's not clear what's causing the readings to change when you have a very bright pattern up for a period of time on the OLED. Some believe it's the brightness limiters, some the power supply, some the individual pixels heating up thus changing their output. My guess it's probably all three that are involved to some extent.
Please note that I found that the Pluge pattern works best but you can use any low intensity pattern as long as the screen stays on.
