Luminance Adjustment in i1Match Not Showing Change
Profiling the monitor and changing the brightness level during luminance adjustment however the software will not reflect the change in the value and the value many times reads zero.The profiling software cannot measure the changed Brightness / Luminance as long as the window of the control panel Displays is still open particularly on iMac monitors. Adjust the Brightness slider as desired, close the Displays control panel, then wait a second until the software has actualized the measurement values.
If needed, open the Displays control panel again, adjust Brightness again, close control panel and wait for actualized measurement values. Repeat this procedure until you have reached the desired Luminance.
