Windows 10: Windows 10 Brightness control for external monitors

Hi, so you can adjust the brighntess of your monitor via hdmi, its an hdmi feature and for macOS there is a programm called Monitor Control which really changes your brightness of your monitor

Is there an app for windows too ?

Why isnt it in the system itself

monitor brightness?

Hi Tom,

To change your Windows 10 monitor brightness, we suggest that you follow the steps below:

• Click the Windows logo; then, search for Control Panel.
• Select Hardware and Sound.
• Choose Power Options.
• On the next screen you should see brightness slider at the bottom of the Control Panel window.
  

We would appreciate it if you could get back to us and provide us your feedback.

 

External Monitor too bright

Acer external monitor on Windows 10 32 bit.

There is no physical button on the monitor offering brightness control.

There is no way of getting into the User option which you can move to but not change

And Windows does not offer a brightness control/slider

Help!

 

How to get Windows 10 to control brightness of EXTERNAL Monitor connected to laptop computer

My SP3 (Windows 10, i5 4300) is always connected to an external monitor through the mini dp with an HDMI adaptor and cable to the monitor(s)

but the brightness setting from Windows itself can't control the brightness of external monitor(s)

for instance, when i slide the brightness bar only the brightness of the SP3 itself will change but not the external monitor(s)

I have installed most up to date drivers for the graphic card and the monitor(s)

Hard control on the monitors will be sort of disabled as long as connected to SP3 (nor an older laptop with Win10), the slider can move from 100 to 0 but brightness won't change

However, even though the hard control can be made working, I still not gonna use it as I would prefer the auto dimming function that's come with the SP3 or most other laptop nowadays.

I have seen someone say HDMI or DP can't transfer hardware control info/ command which i doubt..... if that's the case then are we suppose to switch back to D-Sub?

I currently using Pangolin to "Dim" the external monitor, however it isn't a genuine control. Instead it's adding a layer of grey (or other color) on top of what's displaying. The Windows menu, context menu and task bar ain't dimmed. And when doing screen
capture, the pictures are greyed per the "dim" amount.

So my question is is there anyway that I can get the SP3 (or other laptop) to control the brightness of external monitor(s).

ps from my memory I'm having this issue since perhaps more than 10 years ago when my desktop has DVI-HDMI connection with the monitor.
