U2719DC, 2018 MacBook Pro, no USB-C signal
I'm trying the simplest setup described here =
Using a Dell UltraSharp USB-C Monitor with a Mac
When I connect my U2719DC, I see the following message:
Things I tried:
- Hard reset the monitor
- search for drivers as described here
- force detect displays by going into System Preferences > Display (holding Option) > Detect Displays
- reset NVRAM
- reset SMC
The U2719DC works. I used it a few months with my old 2015 MacBook.
It was connected through MacBook mDP > hub with DP output > DP cable you shipped with the U2719DC > U2719DC DP.
Thank you for your help.

The cable that Dell shipped with this monitor works with my MacBook Pro (15-inch, 2018). I didn't connect the Monitor to the MacBook properly. While connecting the cable to the monitor was fairly easy and smooth I can't say the same about connecting it to the MacBook Pro.
I already ordered a Thunderbolt 3 cable that works as well.
Some things to keep in mind if someone is struggling with the same problem and uses USB Type-C for the first time:
- while trying to connect Dell's cable to the monitor you might have the feeling that you pushed the cable all the way through but you didn't.
- unlike any other cable you've used in the past few decades, USB Type-C in MacBook Pro has to *click* to be fully connected
- Apple's Thunderbolt 3 cable gives me the feeling that it has the right size and it'll connect. I think it's smaller than Dell's cable, and it connects/disconnects much easier with my Mac Book Pro.
@DELL-CaresI would consider reaching out to your hardware department and doing a comparison between your USB Type-C cable and Thunderbolt 3, I can imagine that they're different in size.

Hello,
I recently bought this U2719DC. I opted for this model because of the USB Type-C connector that I expected to work with my MacBook Pro (15-inch, 2018).
The problem is that it doesn't. When I connect the U2719DC to my MacBook Pro with the USB Type-C cable that Dell shipped with its monitor, the monitor shows "No USB Type-C signal from your device".
I tried:
Thank you in advance.
Per the sticky, "Dell monitor, Apple FAQ", have you also posted the issue on the Apple Forum to get their advice? A simple search out there shows 13 threads. Dell-Admin

Are you using the charging adapter/cable that came with the MacBook Pro? Try using the USB Type-C cable that came with the U2719DC.

Hi,
We haven't heard from you.
Were you able to run the diagnostics?
