Controlling brightness on Surface Laptop 3

I am using a surface laptop 3 and would like to control the brightness. It is not letting me. 

It has 2 function keys dedicated to brightness, one brighter and one dimmer, and these bring up the little graphic slider to show a change in brightness, but they each move only one step, cancelling each other out, and producing no change in brightness, whether the device is plugged in or not. 

When I look in settings, I find nothing useful. A link to advanced brightness settings launches bleeping Edge and takes me to Bing (my default browser is Chrome) which led me to settings that let me give the display a nighttime spectrum (or whatever it's called) but that's not what I'm looking for. I just want to make it a little less bright before it burns my retinas, like a regular display brightness dimmer.   

When I search for info on this, I'm led to believe I need to start doing manual driver updates.... and if that doesn't work, try resetting Windows altogether. Which seems kind of extreme.... since if I'm running Windows 10 Pro 20H2 and it's kept up to date by Windows itself, and it's a Microsoft device without any third party extras thrown in to mess things up, why shouldn't it just work? 

Why would Microsoft give the Surface Laptop 3  two buttons for a restricted brightness range that doesn't actually do anything? My Surface Pro 6 has a fully usable range from real dim to real bright. Why restrict it here?

I'm missing something.... right?    

Anyone know about this?

Hi, no not really missing anything. Typical fashion of MS to do something and do it 1/2 -----.  Try F.lux : https://justgetflux.com/

As for browsers there are extensions for firefox and can be used on chrome and some for chrome (no idea never used ever ever ever) If like Dark Mode/ https://www.google.com/search?client=firefox-b-d&q=firefox+dark+mode+extension

or what other there is offered switch your interface in Windows Personalization in Settings.  So many things you can do.

Belated thanks for the replies. 

Still unable to change the brightness on this Surface Laptop 3, 15" Intel, Windows 10 Pro. 

What I'm trying to do is nothing special, just have the screen be less bright. 

When I go to Settings->System-> Display there is a slider to change brightness but it does nothing at all. When I try to use the buttons on the keyboard designated for increasing and decreasing brightness, the on-screen slider opens and but the up and down brightness buttons only move between two fixed points, and at neither point does the brightness change. 

It's as though brightness adjustments have been either disabled. In the animation below, the brightness should change as I slide the horizonal on-screen slider, or the control vertical slider with the keyboard. 

What would account for this? It's a newly reset device, fully up to date.
