Dell U4919DW / MacBook pro 5k issue

Jude O so does 5120x1440 not work via the display port of the dock? (If you can check). I’m gonna get that dock, I am just wondering if I’ll need to buy an extra adapter if it won’t work via DisplayPort. Cheers

The Samsung CRG9 49" does not have a Thunderbolt 3 port so it cannot get better quality by connecting it to a Thunderbolt 3 port of a dock. Also, the MacBook Pro (13-inch, 2017) has Intel graphics which does not support anything better than DisplayPort 1.2.

I just got a Samsung CRG9 - a 49" display supposed to run at 5120 x 1440. The resolution I am getting is close 1980 x 1080.

Am running an MBP 13" 2017 with 16GB memory, Intel Iris Plus Graphics 650 1536 MB on OS X Big Sur. So none of what works for you both, works for me.

Text on the new display is looking squished, no matter what I do. I have tried out SwitchRes X. Don't know whow to make it work!

I have also ordered out an M1 mac! Totally at sea. ANy help would be appreciated.

Thanks Grant. Just made SwitchResX work it at 3380 x 1080 @30 Hz. So text is no longer distorted, though I am not getting the higher resolution. The screen now is gorgeously wide. Its clarity is the same as the earlier 27" display.

If I create a configuration of 5120 x 1440, at even 20Hz, the OS/driver simply doesn't accept. Will keep trying.

This screen of the CRG9 is capable of 100Hz refresh at 5120 x 1440. Will my M1 MBP 13" which is on its way help? As of now, SwitchResX does not support M1 Macs. So don't know what I will do with the new Mac. I will surely try with a USB-C to DP cable (instead of USB-C to HDMI). Is there a possibility that just the cable change will enable the Mac to work at higher resolutions?

One more query - does the M1 MBP 13" support 2 external displays? Then I may even prefer to have 2 x 32" 4K displays, which have a much sharper image. (But wont be the same as 1 curved display which is so blatantly easier on the eye. Many have doubts on that. My Belkin adapter has a DP and a USB C, which can connect to 2 displays, leaving 1 port on the MBP free.

Thanks in advance.

<< does the M1 MBP 13" support 2 external displays? >>

It most definitely does NOT support two accelerated displays.

It will support a single display as large as the Apple 6K display HDR.

There are add-on devices that support "fake" displays (not for full-motion Video) that use DisplayLink software and hardware.

I believe the fix Apple made for Kaby Lake and Coffee Lake to support timings with > 4096 width could have been made for Skylake too but Apple chose not to do that. You can test that in Linux or Windows.

Greetings,

just wanted to add that this is an issue with DELL U4021QW as well. While 60 Hertz is an option on my 2018 13" MBP, the display blanks when choosing it. The display works fine at 5120x2160 30 hertz.

The PItA is that the MacBook Pro defaults to 60 Hertz when closing the lid. As such, I need to leave the MacBook Pro open all the time.

I'm tried going through a Caldigit docking station, and also tried a DisplayPort cable - both to no avail.

Please let me know if you hear of a fix, or if you know of a way to limit the output to 30 hertz (eliminate 60 Hertz as an option).

Thank you,

John

Thank you - "funny" thing is that I for the last three months have had a 34" LG monitor attached - same resolution. Worked just fine, but the DELL offers more real estate.

As such I think there's something the some of the answers above, that indicate that Apple needs to manually add support in the OS.

We will see...

Welp, it seems the new 10.15.7 2021-002 update has officially killed the ability to use an external display using USB-C to DP. Prior to the update, I was using my Monoprice UW 5120x1440 monitor in PbP mode, with one input over USB-C to DP and the other over HDMI. This was my workaround to utilizing this monitor since I couldn't push the full resolution but now it seems it doesn't work at all anymore. I can still use the HDMI input, but the DP input has completely stopped working.

The Thunderbolt 3 to DisplayPort cable arrived .... and still no difference! I'm only getting 3840 x 1080

I'm starting to hit a wall at the moment ......

That's correct ... so far I've not been able to produce the full resolution from my Mac Mini (2018).

I'm now wondering if the fault is with the monitor or the Mac?

Hope that they are able to give you a solution!

MrADeveci, thanks for keeping us posted on your progress. Looking forward to a resolution soon.

Agreed, thank you MrADeveci!
