Dell Display Manager Hotkey

With the Dell Display Manager dmm.exe there are command-line parameters to allow some remote control.

They are as follows:

  ddm.exe /IncControl 10  //to increase brightness

ddm.exe /IncControl 12 //to increase contrast

ddm.exe /DecControl 10 //to decrease brightness

ddm.exe /DecControl 12 //to decrease contrast

The default with no second figure set is 1 or 1% – so in my example I use 5 for 5% like so:

ddm.exe /IncControl 10 5

To increase by 5%

I use the excellent Windows program AutoHotKey, which is free, to do this:

Here is my AutoHotKey script snippet:

#F2::Run "C:\Program Files (x86)\Dell\Dell Display Manager\ddm.exe" "/IncControl 10 5"

#F1::Run "C:\Program Files (x86)\Dell\Dell Display Manager\ddm.exe" "/DecControl 10 5"

This would assign WIN+F2 to Brighten by 5% and WIN+F1 to Dim by 5%


You can also do it with Windows natively using the built in shortcut method:

To create a shortcut using Windows native system Right click on the desktop (or where ever you want it) and chose New > Shortcut then enter the following in the Target: dialog field

"C:\Program Files (x86)\Dell\Dell Display Manager\ddm.exe" "/IncControl 10 5"

and choose the Shortcut you would like to use in the Shortcut key: dialog field. You will need to create two shortcuts; one for Inc and one for Dec.

It should be noted that the Dell Display Manager will need to be started and running in the background.
