Monitors used to have easy rotary buttons to adjust brightness and contrast. Though I don’t remember it actually being necessary that often. Of course, the monitors rarely changed location.

In assuming you are not using your keyboard to set brightness because it’s an external display plugged into a laptop? Search for a DDC application for your desktop, it’s amazing, the brightness controls of your laptop will then control the external display as well. I use lunar on my MacBook, it was a revelation.

Or switch to HDR if you have a capable display.

I was pleasantly surprised that HDR also means you can control brightness - it is all software I that case!

And the brightness keys on an external Apple keyboard work.

According to my (limited) testing, you can only control brightness when the transfer function used on the HDR content you see is HLG. When it is PQ, the luminance seems to be “absolute” and ignores the display’s brightness settings.

I prefer buttons on the monitor.

Using a game comtroller to change brightness is like driving a car from the back seat.

That’s not the problem. Analog dials were still easier and more convenient. I’m talking CRT days. Like these: https://i.ebayimg.com/images/g/M9cAAOSwrt5ncwpj/s-l1600.jpg

You could probably program keypad knobs like these to do the same: https://m.media-amazon.com/images/I/71s7PGYBkkL._AC_SL1500_....
