MacBook Pro 13" Retina 2019 Samsung CRG90 resolution issue

The issue with that is, the specs for the machine state it IS capable of driving it. If this fell under a compatibility issue with the Macbook and 32:9 resolution monitors, Apple wouldn't state that the resolution it's capable of is above what we can't get.

I have a ticket opened with engineering as we speak in regard to this issue so I will be getting official word on what's going on exactly and if Apple has been misrepresenting the external monitor capabilities of the 2019 Macbook Pro 13''.

Hello lukkin, 

Thanks for reaching out to the Apple Support Communities. From your message it appears that the external display that you have is reporting a different resolution than the one you have selected in Settings on your MacBook Pro. 

If this is correct, take a look at the information in this article to see which models of MacBook Pro support different display types: Use 4K displays, 5K displays, and Ultra HD TVs with your Mac.

Cheers!

All 13 inch MBP with Intel graphics fail to deliver the output of 5120x1440... I was going to purchase the MBP16 with Radeon video card in order to finally get proper resolution out of my Samsung CRG9, but then came up to the experiment.

I have MBP 13 Late 2017 with Intel Iris Plus 640 graphic card and it was unable to give 5120x1440 resolution to the external monitor.

I purchased HP Omen Accelerator (150EUR) + Radeon RX570 video card (170 EUR) = 330 EUR (in my case got additional discount from the store of 90EUR, making the whole purchase 240 EUR big).

MBP13 connects to HP Omen via Thunderbolt 3, and then HP Omen connect to the Samsung CRG9 with one Display port. And this is the whole magic. Please see screenshots below:

Thanks for this feedback. I am running the CRG90 on my Macbook Pro 13" 2017. Apple says I am scaling 5120x1440. Samsung says I am only getting 3840x1080. I tried to change the resolution on the mac multiple times and no matter what resolution I am running the Samsung monitor ALWAYS reads 3840x1080. I ran a browser and it shows I am running 5120x1440. But you experience suggests it IS NOT the 5120 Res.

I am unsure what I am running, see attached pic. What device did you pick up and did you notice it improved the monitor resolution? I am finding the text on the screen right now to be very blurry compared to my previous 4K s27" screen.

Hi lukkin,

In the screenshot you have Scaled resolutions checked, if you select Default for Display do you see the appropriate resolutions?

If not and your display is still reporting a different resolution, check and see if there are any internal settings that the display has. If you're not sure, you can check out this link for the user manual for the model display you have, as well as how you can reach to the manufacturer for more help: 49" CRG90 Series Curved Ultra-Wide Monitor. 

Cheers!

I have the same setup. Read a lot about it and it seems that all the 13 inch lapops with Intel Iris graphic cards are unable to drive our monitor (crg9). 15 inch or 16 inch laptop with Radeon video cards will run the monitor in its proper 5120x1440 resolution.

one more option is to connect external eGPU.

Thank you for your reply. I bought the 49 inch LG ultra wide and I'm having the same problem with a new Mac Mini.

I would assume that an eGPU would correct the problem with the LG just like the Samsung.

Hi Lukkin

What connections are you using? I have the exact same setup and having issues too.

Thanks

Mike

I don't understand your complaint. Graphics/Displays says your display IS operating at 5120 by 1440.

What leads you to believe it is operating at anything else?

Did you ever figure out whats going on? I have the same monitor and same computer. What cable are you using? I can't even get 5120x1440 as an option.

Interesting. Both of those cables you linked appear to be compatible since they offer higher than the resolution of the monitor. I wonder what is going on....
