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 think you should be using the DisplayPort input, based on this item under specs:


Scanning Frequency

DP1.4 : 5120x1440@60Hz (FRC)

HDMI2.0/USB-C : 3840x1080@60Hz (FRC) 2560x1440@60Hz (FRC)


To me, that says you only get the highest resolution over ONE input using DisplayPort 1.4 input.

Apple sells such a cable, rated for 5K

Thanks for the update. I had a similar experience where the 'senior engineer' asked me to reset the display settings....... even though what they asked me to do was for the HDMI which doesn't even support this resolution!


It's worrying that this level of 'senior engineers' either do not actually know what the **** is going on, or they are trying to stall this whole scenario for as long as possible, whilst someone else can fix it via some kind of software update.

It looks like LG is jumping in with their own 32:9 5K monitor. Looks like our options are increasing. So far I'm seeing three monitors that are both 49" (32:9) and 5K resolution: Dell U4919DW, Philips 499P9H, & LG 49WL95C-W. The last two are yet to be released. Does anyone know of any other models (the Samsung has the same aspect ratio but not the resolution)?


If the compatibility issue is unique to the Dell model, I don't know how much interest Apple will have in making it work (we haven't seen them show much concern as of yet). But if the compatibility issue is going to be with any 5120 x 1440 display, I'm hoping that the release of all these monitors will motivate Apple to get the display issue resolved.

I’ve read this a few times and thought I’d pitch in as my U4919DW is arriving tomorrow. I have a 13” MacBook Pro with Touch Bar.

Forgive me for clarifying but are we saying that even though Apple say: “Supports a single external display at a maximum resolution up to 5120x2880 at 60 Hz at over a billion colors via Thunderbolt 3 (USB-C).”

It doesn’t? Is that because the monitor is USB-C and not Thunderbolt 3?

And the Moshi Thunderbolt 3 to DP adaptor doesn’t overcome that limitation?

Philips states in the short PDF spec sheet compatibility with “Mac OS X” for the 499P9H:


https://www.download.p4c.philips.com/files/4/499p9h_00/499p9h_00_pss_.pdf


Quote: “Plug & Play Compatibility: DDC/CI, Mac OS X, sRGB, Windows 10 / 8.1 / 8 / 7”


(3rd page, middle column). So theoretically, this has to work :-)


Pro: The Philips offers, next to some SuperSpeed USB ports, a Gigabit ethernet “dock”.

Con: Couldn’t find a “local” (means: within Germany) dealer offering the Philips yet, found only one in Denmark. Seems to be a bit too early as Philips only just released this thing. Spec sheet is online, but the product can’t be found on the Philips page yet.
