Hello,
On my old Lenovo monitor, I used to be able to control the brightness and contrast using software that uses the
VESA Monitor Control Command Set and the
DDC/CI Protocol.
My current monitor (XB271HU) also supports DDC/CI, however,
can not change brightness, only contrast and color values.
But I have found out, that when you set the XB271HU into
Factory Mode (by holding Game Mode Button + Power Button, while monitor is off), you can change the brightness!
So it seems that the VCP code 0x10 for changing brightness DOES work, but is somehow
locked outside of the Factory mode.
Does anyone know how to make VCP code 0x10 change the brightness in Normal mode (outside of the Factory mode)?
I know this is very technical, but I just want to be able to change brightness and contrast per software, as pressing the hardware buttons is really tedious, and I change those settings A LOT.
Thank you,
Tom
