I have purchased a new HP Desktop All-in-One 24dp0818. I find the minimum brightness too high. Is there a way to reduce brightness below the minimum? I have tried Night mode and I am not comfortable with it. Further, I also tried changing the color settings on the Intel Graphics Command center. But the brightness still remains high. Is there any way to fix this? I tried to calibrate the display. But I do not know where the on-screen display controls are. Where is the OSD menu button in HP Desktop All-in-One 24dp0818?
