Brightness control on external monitors has never been supported in Windows though, partially due to issues with displays that have poor write endurance on internal storage.
- poolnoodle 10mo agoI change brightness all the time with a little tool called Monitorian.
- tylerflick 10mo agoMonitor brightness is controlled over CEC which is just i2c. Windows most certainly supports this on an OS level.

- user_7832 10mo agoIt might not be an "internal windows" tool, but I have controlled an ancient monitor (I think over VGA?) using a 3rd part app on windows. The buttons had broken, but software control worked just fine.
