Due to Apple hardware not being tested by Dell, I am guessing that you are connecting like this? MacBook Pro Thunderbolt/mDP out --> U3415W mDP to DP cable --> U3415W DP in (next to the HDMI in)
From the U3415W User's Guide page 31. You would choose DP not mDP and Disable =
Yes! Thank you for that page reference. Holding down for 8 seconds gave me the DP config message and with DP 1.2 disabled, not only is the monitor getting a signal from the mac, the mac is working at normal speeds.
Yay! I love this monitor size and i'm so happy working on it :)
this worked to bring up the DP config menu, which in turn solved my issue completely. mac is working at normal speed with the DP 1.2 disabled and the beautiful external monitor is glorious. Thanks Chris M
I am trying to connect a Macbook Pro to a Dell u3415w using an HDMI cable and a USBC connection, it is saying that it cannot see my MAC. I have tried to access the Main menu but cannot access that only the small HDMI menu. please help
