Windows 10: Night light/brightness control not working on external display Surface Pro X

Hi!My external display is connected to a Surface Pro X via USB-C/DisplayPort cable.I can set the brightness level and Night light on the Surface main display but nothing changes on the external display.I have already seen posts about this: https://answers.microsoft.com/en-us/windows/forum/all/night-light-on-second-monitor-with-usb-c-to-hdmi/96c509e1-914c-4efa-aa97-b10e58545018but there are quite old, so I was wondering whether Microsoft did something to solve this since then.Thanks a lot for your help.Kind regards

Broken brightness setting and Night Light

Hello,

Since scheduling night light I'm unable to change screen brightness setting. Night light strength adjustment also not working even in night light schedule "off" time. Turning off the schedule switch altogether solves night mode strength lock but global screen
brightness still locked, ie the brightness slider moves but screen brightness doesn't change whatsoever ie, broken.

I've never installed flux etc, only the native night mode on the new surface 7 with up to date windows. Brightness slider worked as expected before scheduling night mode.

When night light schedule is turned off via switch in settings global brightness slider is still ineffective and broken, it slides to no effect.

Many thanks for reading.

Brightness controls and night light

Since the latest windows 10 creators update was installed on my hp pavilion laptop I have no controls to enable me to manipulate the screen brightness. There is no longer a button in the quick action centre (used to be a sun & % brightness button), nor is
there a brightness slider in the display settings as there used to be. Also, there is no brightness function in the settings 'add or remove quick actions' setting, and nor do the keyboard brightness keys work.

Also, the night light function used to work but now, even though the controls are there they are greyed out and will not function.

Can anyone relate to this or come up with a fix?
