Windows 10: How to adjust brightness on external monitor, IN OPERATING SYSTEM.

Is there a way to change the brightness on an external monitor hooked up to my Surface? The brightness slider under display settings is grayed out. (Windows 10)


I can adjust the brightness through the buttons on the monitor itself but it's a terrible interface. This is something I need to do daily as the sun sets so I'd much rather be able to hit some hot keys.


Monitor is an Acer.

Can't adjust brightness on external monitor

It's got everything to do with Windows 10 because that's the operating system that should let me control the brightness of an external monitor. The Surface Book is both a tablet and a laptop, so there's nothing weird about connecting an external monitor
to it. What do you mean by "this country"? This forum is international.

 

HDMI external monitor: adjust brightness according to profile/day time


Hello,
OS: win10 Familly

I use an external hdmi monitor on a notebook, in that case I only use the external monitor (viz no dual display).

I can adjust the brightness of:
* the notebook screen with the "Sun up" and "Sun down" key on the keyboard.
* the external monitor with the menu on the monitor, but modifying on the monitor is cumbersome: need to call the menu, then "Picture", than "Brightness", then OK, then adjust with + and -, then finally confirm.


As the day light vary, from a bright sunny to dark, I noticed it's very relaxing to adjust the brightness between 100% (sunny) to 40% (dark).
How is it possible to "easily" adjust the external monitor brightness?

1/ The "Sun" up and down key only functions for the notebook, not for the external monitor - it's quick & easy.
Is it possible to apply to the external monitor?

2/ There are browser add-ons for that, but then it's bound to the browser, not all other apps.

Ideally, I would like to create 3 profiles of brightness or have some simple + and - keyboard shortcuts to adjust the hdmi brightness.

Thanks
