Recently I purchased a Dell U2719DC display to replace the aging 19" Samsung monitor I was using with my mid-2013 MacBook Air (Intel HD 5000 integrated graphics). The display is beautiful, but I have one problem:

When connected to MacBook via an Amazon Basics mini-DP to DP cable, the monitor doesn't work. I just get a "No DP Signal from your device" error on the monitor, and then it goes to sleep. If I cycle the power on the monitor, the display on my MacBook will flicker like its trying to drive the Dell... but the Dell just resumes with the same error.

I've tried futzing with the display settings on my MacBook. My Mac recognizes it's connected to the Dell display, the resolution and refresh rates are acceptable. I've tried endless reboots of the MacBook and cycling the power of the monitor... no dice.

I confirmed the cable is good. I connected the Dell display to my Lenovo ThinkStation with the same cable, and the monitor displays properly.

Any thoughts?

Thanks,

Jonathan
