- 111111IIIIIII 3y agoSorry, I am not quite sure what that is. Sleep works great with my PC (motherboard is ASRock WRX80 Creator) and M1 MBP, but I can only adjust brightness through the OSD.
- Toutouxc 3y agoThere’s a Mac app called Lunar that uses DDC (a protocol for sending commands to a screen) to allow you to adjust the brightness and volume of an external monitor with the usual keys on your MacBook keyboard (in clamshell mode at least) or with a slider. Very convenient, can’t recommend enough.
- 111111IIIIIII 3y agoOh OK sorry but yeah I wouldn't use that. If this is usually supported on Dell monitors, I would bet it works on these. Personally, I rarely adjust brightness on my desktop displays and my ZMK keyboard volume buttons work reliably cross-platform.
- Toutouxc 3y agoI you don’t need it, you don’t need it, but I don’t understand the first sentence. Many different displays support DDC, my Philips at home does and the Dells and I think BenQ that we have at the office do too.

- garyfirestorm 3y agoi know my old Dell Ultrasharp U2415 supports this feature. There is a tool in linux with which you can switch input, also dell has a display manager in windows which allows you to perform the switching and controls. I totally love it!

Looks like it does support DDC brightness control: https://f.alinpanaitiu.com/nAa7gs/Image.png https://f.alinpanaitiu.com/nAa7gs/Image.png I checked this on https://db.lunar.fyi https://db.lunar.fyi using the following query: select control, name from displays where name like '%U3224K%' Can’t be sure about DDC input switching though, I have no way of knowing that it works without trying it in front of the monitor. DDC reports success even if the command failed to switch the input.
- nathancahill 3y agoJust wanted to say, thanks for the fantastic app. It's the first thing I install on a new computer.
