I have an Acer laptop running windows 10, and I occasionally connect a Lenovo external monitor through HDMI to see things in a bigger screen. Unfortunately, the external display defaults to brightness 70 when I connect it. I then have to manually press the buttons to reduce brightness. How can I make it so that it defaults to a brightness of 0?

  • @Sanu_012, no, I was looking for something else. Using softwares would not be automatic. I would have to set it each time I open the external monitor. – Analon92 May 03 '20 at 04:43
