I have the new Apple Mac mini 8.1 with Intel i7 3.2Ghz and updated to Catalina latest update. I do not have the option to go higher in resolution than 1920x540? Connected via Dell supplied HDMI cable. Bought this monitor specifically for this Mac. What can I do?
An update, was able to increase the resolution via the USB-C cable to a max resolution of 3840x1080. After trolling the internet, found out that this is the max resolution for Mac mini via the USB Type-C cable. If the HDMI cable is a true 2.0 cable, am I able to get to the maximum resolution of the monitor?
For Dell Technical Support to offer assistance, you need to test the Dell U4919DW on a true Windows OS PC.
Read the sticky at the top of this Monitors Forum, "Does my Dell monitor have Apple support?"
The U4919DW HDMI cable provided and the HDMI ports are 2.0. We cannot speak to the not tested/validated by Dell Apple operating system. There are no Apple OS drivers on the U4919DW driver page.
You should read the U4919DW threads on the Apple Forum. If need be, start a new thread on the Apple Forum detailing your issue. Perhaps they can offer some advice on how to get our monitor working on the Apple PC.
