Monitorian VS ddccontrol

Most modern displays support DDC/CI or whatever it is that lets your PC talk to the monitor and adjust brightness (and other settings).

Monitorian and other apps let you adjust those settings from your PC.

I feel like this is much simpler than many things called out so far, but I haven't found a great replacement coming from Windows for Monitorian. It's a small app that sits in your tray and lets you adjust your monitors' brightness levels. That way you don't have to press physical buttons on your monitors. It's also very nice to be able to lock multiple monitors' brightness levels together so you can change them at the same time.

I don't have a solution but Monitorian might tide you over. Works on external displays too

Monitorian is a nice alternative to the native brightness slider because it also works with external displays.

There is also Monitorian for Windows:

Why do they not allow doing the same for external monitors using DDC? There are several apps that do just that.

Try ddccontrol on Linux or https://www.nirsoft.net/utils/control_my_monitor.html on Windows.

ddccontrol and gddcontrol works well

If I were you, I would take a look at ddccontrol. It's a utility that allows you to query the state and send commands to your monitor via the command line. I currently use it to increase / decrease the brightness of my monitor depending on the time of day.

i have always hated having to fiddle with the buttons on the back of my monitor to change things such as the brightness but now i have finally found a better way https://github.com/ddccontrol/ddccontrol

Before I look into automating it, I wanted to get it working first. For this, I have a tool called ddccontrol (https://github.com/ddccontrol/ddccontrol). But this needs root privileges. So I'm just wondering if there are other ways, since I couldn't find any.
