On my ASUS laptop device (Win 11 Home 26H2, Build 26300.9457) I see a brightness slider so I can adjust the screen brightness. Photo 1.

On my GMKtec desktop device with a Benq monitor (Win 11 Pro 26H2, Build 26300.9457) there is no brightness slider so I am unable to adjust the screen brightness. Photo 2.

Does anyone know how do I get the brightness slider to appear in the GMKtec display settings?

First off, you have the labels backwards on your pics, assuming the 1st sentence of your post is correct. :-)

Secondly, I would check on the BenQ's On screen display or what ever it has. There should be a brightness setting there too.
Also, if you have to run the AMD Adrenaline software for the integrated graphics part of the CPU... there should be a brightness setting there as well.

    Still assembled, still runs. Haven't turned it on for 15 years?
Typically desktops don’t. Use Monitorian if you want one. Or one of many alternatives to it.

@wiganken,

Other than the monitor's on-screen menu settings, you may be able to also use option 8, 9, or 10 in the tutorial below from the driver settings.

Thanks. I corrected it.

I have adjusted the screen brightness using the Benq monitor OSD menu. It had been set to 100% so reduced it to 45%. I don't know it had got to 100%. I certainly didn't go into the monitor settings so can't explain it. I'm sure it was okay yesterday but suddenly today it was bright. This is a tedious way of adjusting the screen brightness so I would like the brightness slider if possible. I'll look into @Brink tutorial in post #4.
