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?

I also just upgraded to Big Sur on my 13" 2018 MacBook Pro - and I am getting full 5120x1440 resolution via USB-C/Thunderbolt. Also, over the moon!

Does not work me. Tried that based on this and other posts.

Connect directly to MacBook Pro Thunderbolt port (no USB-C dock) using USB-C to DisplayPort cable?

Display set to DisplayPort 1.2?

Does anyone know if the OP monitor (Dell U4919DW) will work with the new MBP 13" M1?

Please see the above post.

Thanks! I am already using the 4919DW on my 2016 MBP and not getting full resolution. Hoping that upgrading to an M1 would resolve the issue.

I saw a lot of people who have said that big surr fixed the problem. But not on my System. Im still stick with 3840x1080p. I have a MBP 2018 15". Is there a way to archive 5120x1440p?

Are you using ThunderBolt, USB-C or DisplayPort family interface?

Jan 17, 2021 1:51 PM in response to Grant Bennet-Alder

i am using the usbc cable that was delivered with the Monitor. I think that is a Thunderbold 3 cable but im not 100% sure. The monitor that im using is the AOC AGON AG493UCX.

Jan 17, 2021 11:14 PM in response to icallitschnitzel

Have you tried Display Port cable? Or still with HDMI? HDMI doesn't handle high resolutions well. I have posted extensively about this. Big Sur its not a fix.

Jan 18, 2021 12:36 AM in response to Applenut2010

Ok ill try with a usb c to dp cable. but ill be not able to use the usb ports on the display right?

Jan 18, 2021 4:15 AM in response to Applenut2010

I just ordered a 4k @60 hz usb c to display port cable, i hope this will work :) if its not working ill have to check for another usb c dongle xD

The chatter here is that Big Sur is a requirement to go wider than 4096 pixels wide.

(and only supported for 2017 and later MacBook Pro, which you have).
