Question

For OLED, in the readme, it mentioned that

OLED or mini/micro-LED displays and televisions are fully supported using gamma table manipulation (this is a no-compromise solution for this class of displays).

Would someone please share some light on the following questions:

Will MonitorControl automatically determine whether the connected monitor is an OLED/Mini LED and use Gamma table manipulation for brightness control?
(More in the depth of the topic) why controlling the brightness using gamma table manipulation on OLED/Mini LED is no-compromise? Compare to normal LCD monitor? (I tried to search on Google but couldn't find any relevant topic)

Hi there,

No, you need to disable hardware brightness control so the app will fall back to gamma table manipulation
OLED displays don't have a backlight so hardware backlight control does not make much sense. With mini-LED the best approach is a combination of hardware and gamma control (if supported) as even though mini led displays can scale the mini-led zones to full black using software-only, the algorithm will create more blooming. Micro-LED displays (like OLEDs) should not have this issue (although micro-LED displays are very rare, Samsung has some super-expensive expandable micro-LED TVs).
