Dell U4919DW / MacBook pro 5k issue

Hi,

I have just purchased the Dell U4919DW monitor to use with my early 2018 MacBook Pro 13", but unfortunately I cannot choose full resolution 5120x1440 in the settings, max is 3840x1080. I have tried the app SwitchResX to manually set the 5k resolution without luck, only scaled.

From this link I read about my MacBook before purchasing the screen that:

"this model supports a maximum resolution up to 4096x2304 at 60 Hz at millions of colors on two external displays or a single external display at a maximum resolution up to 5120x2880 at 60 Hz at over a billion colors via Thunderbolt 3 (USB-C)."

MacBook Pro "Core i5" 3.1 13" Touch/Mid-2017 Specs (Mid-2017 13" (Touch Bar), MPXV2LL/A*, MacBookPro14,2, A1706, 3163): …

My MacBook Pro has 4 USB-C ports, I'm using the left ones which operate at full speed (right ones are reduced).

Why can't I get full 5k resolution? Is it an issue with the MacBook, the connection, the screen or perhaps an iOS issue?

Thanks. Updated my devices. Apple Support was very clear to me, that Intel does not work. AMD or M1. It does not matter what MacBook Pro with Intel. But I can not test outside the devices I own.

Agree. I never used any docks. TB 3 cables - no HMDI! And again: what I wrote above, comes from Apple directly (after being in calls with them for hours over the last days).

That should work! It does on my MacBook Pro with Intel. So with AMD that should be ok. The issue is 5120 x 1440 with certain MacBooks / Mac Mini with Intel.
