I noticed that refresh behavior is actually changing when I select different options within testeink utility. Also, the site linked above describes it as a necessary step with very specific options to select. And they seem to deliver the best result to me.
So it’s not simply to test unsupported devices.
Once rebooted the device the refresh is no longer as selected, as I notice ghosting.
That’s why I wanted to understand how to make these changes persistent.
