This is useful if you want to run a full-screen Teams/Zoom meeting or watch a full-screen video, but leave a panel free for making notes or surfing the internet.

Configure the Hotkey

TIP

My example assumes a Dell monitor supporting 80/20 is installed (e.g. U4021QW), and that the PC has 2 cables connected to ports DP1 & HDMI2.

• Run the downloaded ddmhkm.exe to start the DDM Hotkey Manager.
• In the DDM command-line parameters box, type /1:SetPxPMode Off.
• Click in the Select system-wide-hotkey, and press the hotkey combination you want for No-PbP.
• Increment the Hotkey from 0 to 1
• In the DDM command-line parameters box, type /1:SetPxPMode PBP-2H-82 DP1 HDMI2.
• Click in the Select system-wide-hotkey, and press the hotkey combination you want for 80/20 PbP.
• Close the DDM Hotkey Manager.
• Exit & Restart the Dell Display Manager.

TIP

Note that after switching to a new layout it will take 10 seconds or so before DDM starts listening to hotkeys again.
