Windows 10: 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

Hi Marnicia,

You can reduce the brightness of your computer by following the steps below:

1. Select Start Windows logo Start button.

2. Choose Settings Gear-shaped Settings icon, then select
System > Display.

3. Under Brightness and color, move the Change brightness slider to adjust the brightness according to your preference.

Some PCs can let Windows automatically adjust screen brightness based on the current lighting conditions. To check if your PC supports this, in
Display settings, under Brightness and color, look for the
Change brightness automatically when lighting changes check box, and then select it to use this feature. This automatic setting can help you in making sure that your screen is readable wherever you go. Even if you use it, you can still adjust
the Change brightness slider to fine-tune the brightness level.

Note: You might not see the Change brightness slider on desktop PCs that have an external monitor. To change the brightness on an external monitor, use the
buttons on it.

Should you encounter future issues, please do not hesitate to let us know. We are happy to help you out.

 

Extended display settings keep resetting after sleep, hibernate, shut down

My Surface Pro 4 is connected to a Lenovo Ll2223sw Wide LCD via a DVI to HDMI with an HDMI to mini-Display Port adapter (Made by Microsoft). The problem is that the settings (contrast, brightness) that I select on the monitor keep resetting every time
I turn on the Surface or wake it from Sleep or Hibernate. Does anyone have a solution that saves my settings? I assumed they would save since I'm adjusting them via the monitor and
not the Surface.
