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.

make sure you use a Thunderbolt 3 cable to be on the safe side! USB-C cables come in different flavours (the cheapest are USB 2 specs)!

Thanks Nixosp!

It works ok for me, not perfect, but acceptable. One could also go for half-half in pip/pop mode, but then it gets a bit weird, because it is nice to have the window that is in focus, somewhere in the middle of the monitor screen, which is not possible, in the 50/50 setup. I used to work with three screens, wanted to replace that with one seamless, no I have two screens in one hardware frame. 3440*1440 on the left and one 1680*1440 on the right. 5120*1440 in total, but with an invisible fault line. If you choose single colour identical desktop backgrounds, I sometimes forget the fact that there are two monitors. Great workaround.

In the last few days LG has released some updated software for this display. Maybe it will help.

Seconded. I have a dell 49" monitor, with a mac mini and its the same issue. A work around for now is to use PBP to make the screen think its 2x 27, then you can have a vertical resolution of 1440. The downside is the split down the middle of the screen (not bezel but just the break in the screen). Does anyone know how we will be updated when this is actually resolved by apple? Thank you

I would try deleting swichress, I’m getting native 5120x1440.. what device and OS version?

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!

I'm finally get this HI RES with external GPU

buying this

and this

https://www.amazon.com/gp/product/B06ZZ6FMF8/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1

assemble it all according manual and we have desirable 5k

Connection Type: DisplayPort

I am now capable to confirm that eGPU

I completely agree. If you load Window 10 on the new Mac Mini it can run the display at 5120x1440 so the issue is display drivers within O SX that Ned to be fixed. It should not require more hardware to be purchased to support any of these current ultra wide 32:9 displays on the market...

I have the EGPU working with my new Mac mini. I purchased a GPU https://www.newegg.com/sapphire-radeon-rx-580-100411p8gocl/p/N82E16814202278?Item=N82E16814202278&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-

and a Thunderbolt 3 EGPU Case https://www.bhphotovideo.com/c/product/1445133-REG/razer_rc21_01310100_r3u1_core_x_external_graphics.html

This is working great with this monitor. I hope that helps.

Nice! It looks like it is "Scaled" according to the attached screen dump. Does it also work with the "Default for display" option?

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.

Lots of monitor updates on 6/20:

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

I haven't heard of any fixes or seen any updates from apple to address the problem. I think it's just due to the nature of the monitor being 49 inches wide, that the OS has no support for that resolution at the moment. I was in the same boat in prior to buying the monitor, apples own Q&A stated that the Mac mini should support 5120x2880. When I bought the monitor, I was definitely surprised and bummed out that it was not true.

I remember reading somewhere the apple actually had an update for this monitor: LG 34BK95U-W UltraFine 34, a monitor that apple is also selling on their store website I believe. This monitor has a resolution capable of 5120 x 2880 at 34 inches. My guess that's where the "5120 x 2880" support is at that monitor size.

Cable wise, it didn't really matter. I bought various thunderbolt 3 cables, even the apple official one. No changes at all. So the cable is not a factor.
