MacBook Pro 2020 support for Dell U3818DW monitor
I recently purchased a new 13" MacBook Pro (MBP, 13”, 2020, Four Thunderbolt 3 ports) and am having trouble having the machine display on my Dell U3818DW monitor that I had purchased a year ago. I'm running Catalina 10.15.4.
I have received the following messages on the monitor:
- When trying to connect via USB-C: "No USB Type-C signal from your device."
- When trying to connect via HDMI (with dongle to go from HDMI to USB-C to connect to MBP): "The current input timing is not supported for the monitor display. Please change your input timing to 3840x1600, 60Hz or any other monitor listed timing as per the monitor specifications."
I've tried to adjust the settings for the external monitor via System Preferences, but the 3840x1600 is not available (3840x2160 is) and I can't change the refresh rate (even after pressing the Option key and "Scaled" a dropdown for the refresh rate is grayed out).
The monitor continues to work perfectly for my older MacBook Pro (13” Retina, early 2015), also running Catalina, 10.15.4 and connecting via HDMI. However, I'd like to completely switch over to the new machine.
I have seen old discussions on here regarding Dell monitors (including the U3818DW), but none have provided solutions and I hadn't seen a discussion with the latest vintage MBPs. I noticed that Dell seems to provide no support for Apple products.
Any suggestions to make these two play well together are greatly appreciated. I'm really liking the new MBP, but also like that monitor!
