M1 Macbook Air display scaling

Hi my new dual display docking station for the M1 MacBook Air is working really well but the display scaling is super zoomed in and I can’t adjust it in the Settings → Display menu. Is there a work around to change the scaling on the extended display?



Thanks for reaching out to Plugable support! I’d be happy to help with that.

When you have a moment, could you please let us know the following details:

  • The model of your Plugable device (located on the product itself, the box, and the quick start guide)?

  • The Make and Model of the display you are trying to connect?

  • What version of the MacOS are you running?

Thank you for your patience and for giving us the chance to help!

Hi Richard,

It’s the 3900C

Displays are Dell 2417H

I’m running Monterey OS or 12.3.1

It feels like the display is on 125% zoom and I want to pull out to 100%


At this point, I’d like to collect some additional information about this display is connecting to the docking station.

Please keep the dock connected to your system (even though not working) and send the output of our diagnostic utility PlugDebug → http://plugable.com/support/plugdebug to us directly via support@plugable.com with ‘For Ticket 378255’ in the subject line. This will allow us match things up and examine some log files from your system to help determine the next steps.

Please also include your Amazon Order ID number for the docking station purchase in your direct email. Please do not post the Order ID or the PlugDebug file in our public forum.

Thank you for giving us the chance to help!
