37 points · Open discussionMost 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.

In 18-year-old built a computer monitor that doesn't strain your eyesThere are some tools out there that will allow you to bind hotkeys (or at least provide a widget) to send brightness-adjustment commands via DDC/CI over the HDMI/DP cable to your desktop monitor. This may improve your UX. My 2015 and 2021 Dell monitors both support the functionality, with differing degrees of finesse.

In The state of external retina displaysThe Windows equivalent would be Monitorian (https://github.com/emoacht/Monitorian). It doesn't have the adaptive curve algorithm, but I've been using it for over a year and it's indispensable.

In Design Tip: Never Use Black (2012)Submitted since this solves my, and thus perhaps others needs to control their monitors.
GUI and CLI application to get/set various properties of your attached monitors. For windows. Works over the Display Data Channel (eg over HDMI).
In my case, I couldn't (from Windows display settings) lower the display brightness of my external monitor, leading to eye strain when the room is not well lit enough. This enables my to reduce the display brightness with ease.
There is an alternative, which can only change brightness but does so with a minimalistic gui: https://github.com/emoacht/Monitorian (have not tried it).
If not for ergonomics, you can use it to visually be notified when eg a script is finished, by toggling brightness back and forth.
An alternative to _that_ is to use the snoretoast application with something like this:
alias wake

me='date && /cygdrive/c/Dropbox/tools/notifications-w10/snoretoast/snoretoast.exe -t "hello" -m "wake up goddamit" -p "C:\Dropbox\tools\notifications-w10\mindblown.png" -s "ms-winsoundevent:Notification.Reminder"'
thus, you can "longscript.sh ; wakeme". From https://github.com/KDE/snoretoast
