Really curious about the subject possibility. For instance, like we can change brightness on laptops.

I'd like to adjust brightness and contrast at least, from OS. Quickly.

P.S. Unfortunately, the most manufacturers do not allow quick switching with one-click way.

I remember the a one monitor, some gaming one, like ASUS Rog, which has a button for changing presets.

Update 1: If someone could point me at a brand-new monitor model with hot-button to change its profiles, it will be really appreciated.

Update 2 (2022-10-04): Use ClickMonitorDDC (for years) to control monitor brightness. It works ok. Please be aware, some monitors like Samsung Odyssey G9 with HDR, does not support DDC.

In theory, yes. For example, VGA connections allow this through the Display Data Channel, which was later extended to cover HDMI and DisplayPort connections as well.

There seem to be many apps on Google for controlling monitors via DDC, but it's unclear which monitors actually support it (often it used to be supported but just never mentioned in docs). On Linux you would use gddccontrol.

Most modern monitor's hardware settings should be controllable from the PC, that's how professional monitor calibration software do calibrations.

There are quite a few brightness adjustment software (as detailed in this The Windows Club Article) or screen calibration software that can be used to adjust brightness and contrast. I've been using one called ScreenBright for basic screen calibration on and off for a few years now, although it works, it is no longer supported.

Don't forget to check if your monitor's manufacturer has software that can do this as well. Most manufacturers used to ship software alongside their monitors, but that has become extremely rare in the last decade. You can also try to see if you can achieve the desired effect using your graphic's card software's.

You can get a USB to HDMI passthrough which offers CEC control.

The CEC offer remote control of a variety of function.

Device Menu Control – allows a component to control the menu system of another component by passing through the user interface (UI) commands

This suggest you can, but other sites suggest you can't to brightness and contrast. I can't test it right now so I can't say with certainty.

Yes. PC monitor settings can be modified by the PC if the monitor has software in it that permits the settings to be remotely edited. Typically, smart monitors can be configured from the PC by the user.

However, the smart monitor like any other or most other monitor would most often have buttons on the unit itself to manually change settings for display and a power button upon need. That is for fallback purposes.
