MacBook Air Plugable 3.0 Flicker 60hz

Hi there! So I set up my plugable and can get it to display my MacBook Air at 1080p 30hz on a Dell 4K monitor but the moment I make the frame rate change to 60hz the monitor goes black and flickers occasionally. When I use UsBC hub or usb c to hdmi chord I have no issues do 1080p at 60 hz. Any suggestions?


Thank you for contacting Plugable! I am sorry to hear that your device is not functioning as expected, and would be happy to provide additional support.

To help diagnose the issue, may I ask you to please keep the device connected to your laptop and everything still attached (even if not working as expected) and send us the output of our diagnostic utility PlugDebug? →

Once you have the logs, simply send an email to with the subject line of “Ticket 372375” so that we can prioritize that case and match it to this inquiry.

If you could provide your Amazon Order ID (or other proof of purchase) associated with your Plugable device, I would be happy to check on your warranty status as well.

Thank you for giving us the chance to help!
