Mac Mini 2018 and LG 49WL95C-W 49-Inch Curved 32: 9 Ultrawide

I also have this problem. I have found a work-around that is acceptable to me, maybe it is also acceptable to others.

I have plugged one usb-c connection from Mac to monitor and an additional hdmi connection. I then configured the monitor to display both connections on the screen using the pip/pop mode. In my case, I am displaying 2/3 from usb-c and 1/3 from hdmi. This gives me the total 5120*1440 resolution.

As this is two screens from the macs perspective, it can be a little quirky, but works ok for my situation. You may want to display spaces.

Might be worth a try?

Hi guys, I was able to get full resolution using the USB-C cable that came with the monitor!

and I also got sound and brightness working..

I will post a tutorial tonight or tomorrow morning.

I believe it should work with all Mac that supports 5k.

People using the MBP 15"/16" should start their own thread. This is becoming *VERY* confusing. Both the 49" Dell and LG should ultimately work with 15" / 16" if you just take the time to configure things properly.

However, a proper fix is specifically needed for a Mac Mini or MBP 13" with the intel graphics card, as we cannot get a non-scaled version of the 5120x1440 resolution.

Please take the 15" / 16" issues to a different forum; please and thank you!

Take a look on my post (currently it is the latest one there - I am now capable to confirm that eGPU works perfectly. Here is the link: https://discussions.apple.com/thread/250885574?answerId=251975225022#251975225022

Yeah i think its a bug in the new OS, it is super daft:

See https://discussions.apple.com/thread/250737077

Re the Mac mini, I don’t know if its due to the onboard graphics chip specifically.. Is the Graphics on the MacBook Pro making the difference? i.e. with High Sierra on a 2018/20 Mac mini could it work?

Or is an eGPU the only option for the mini..

In any case apple really needs to get a patch sorted.

Thank you for reporting, I have the same issue with you.

It might not be the best solution, but SwitchResX can force the resolution to be 5120 x 1440 (please take a look at the screenshot below). Since what it does is just to scale the 3840 x 1080 resolution into a fake 5120 x 1440, all the UI and text will be much smaller but meanwhile very blurry.

Wish it's a software problem and Apple will solve it soon with a MacOS update.

Guys! I did it!

I'm using the 2018 mac mini with the LG 49WL95C-W (no BootCamp), I bought this screen from July, and it has the same problem as everyone. My resolution is only 3840x1080, until now...

I just bought Razer core x with the Vega 64 yesterday, and using the LG DP cable from monitor to the egpu, but the funny thing is that my resolution was only 3840x1080 yesterday, but when I turned on the computer today...I was wondering why the login screen was getting smaller, so i just log in and enter system preferences to check the resolution. OMG!!!

5120 x 1440!!!!

I've followed all your steps and got resolution in the list BUT WITH "low resolution" mark so it don't give real (take a look on my screen shot) but i see that you have no mark like that on your screenshot - how you did that? do you hi res looks real?

A think you are just alarmed because it says low res, mine was like that too but it went away after a few restarts.

does it look sharper than before the tutorial? Now, if you now switch back to a a lower resolution the panel will remain 5120*1440 but UI upscaling will be what you have set to be. go to about this device -> system report -> graphic/display

And there is a intel version.

I'm sorry, I forgot the attachment. I think we are on the right path...we need a small step. You're help is enormous, thank you again!

I'm starting from fresh install, so I hav't software on board like switcherx & c. If you or any body else have an idea I can test it.

Thanks again.

I'm finally get this HI RES with external GPU

buying this

and this

assemble it all according manual and we have desirable 5k

Connection Type: DisplayPort

I am now capable to confirm that eGPU

I finally got 5K resolution working (5144 x 1440 )with my 2018 Mac Mini on my new LG 49WL95C Ultra Wide monitor. (as per suggested by AlexP788).

I had to spend more money on an external GPU. I purchased the Razer Core X Chroma, with the fancy little lights ($400), you can get it without the lights for $300.

I also purchased the Sapphire Pulse Radeon RX580 graphics card.

Everything works great and it was all just plug and play. See pictures below.

In theory, your 2018 Mac mini can support up to 5120 x 2880 @ 60Hz for 5K 16:9 by connecting from one of the mini's four Thunderbolt 3 / USB-C ports to the DisplayPort port on monitor. I don't know how it would handle the 32:9 ultra-wide mode for this particular monitor.

Lots of monitor updates on 6/20:

Load all that apply and see if it changes the problem? Good luck.

I was about to move on purchasing this combo and was wondering if anyone has seen a fix or even an official acknowledgement of the issue. B&H Photo's staff claims in the Q&A section that there are no issues as the late 2018 Mac Mini, "supports resolutions of up to 1 monitor at 5120 x 2880 @ 60Hz via one of the Thunderbolt 3 ports." Are the problems mentioned port/cord related, or is there lack of support?
