My monitor is more than an arm's length away from me, so adjusting its backlight brightness is quite inconvenient.
Is there a way in Windows to adjust the backlight using the keyboard and/or mouse only. If so, how?
Answer
ScreenBright seems discontinued, but as @wrongusername suggested, pangobright might be an alternative.
I found enable DDC/CI option in my displays' settings. The ScreenBright program was able to modify it, although I think it's GUI is quite terrible and easy to break you custom settings. My screens also flicker a lot when changing brightness. Nevertheless, it has a commandline interface, which is much better. Especially when you create your own GUI (which is around 5 minutes in C#) or use plain Windows shortcuts.
As a side note to the Dell brightness change - I can confirm that it also did work for me. My setup was:
- Dell Latitude laptop (5520 I believe)
- Dell Docking station (the extended version)
- 2xDell u2412m screens, connected via DVI
The laptop itself had a built-in GPU (Intel HD2500). In its software there was a tab called "monitor settings", iirc. It did indeed communicate with the displays and somehow change their built-in brightness settings. I weren't able to do much more (change profiles, for example), and it took quite a while to "initialize". There was also a 2-3 second delay between the setting of the brightness and actual change. I guess it was mostly due to the screens, which changed brightness gradually.
I've updated my PC to the regular workstation, and unfortunately I wasn't able to find similar setting in the NVidia control panel.
EDIT: It seems that my previous setup used DDC.
