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

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.

I just purchased the same Vega 64 and ext thunderbolt 3 box for my Mac trash can. Will see if it works.

in the meantime I found that putting the LG monitor into PIP mode and running the ⅔ and ⅓ view mode gives u 3840x1440 for the ⅔ side and it’s decent enough and enough space on the right for a second laptop or computer.

I followed your guide (thanks), now I can select the correct resolution (5120x1440), but on the info tab, Catalina said that the resolution is 3840x1080...the text isn’t cryspy...it’s like the effect that I have if I set this resolution with switchresx.

I tested the 5.5 step also, the result is the same of the previous user. I think that with your macbook is the AMD chip that drive the monitor itself, but with the mini we are stuck with the Intel’s one.

No, it don't looks sharper. If you look at the attached image, you can see that from system information recap the resolution is 3840 x 1080, but in monitor settings and in full system check, the resolution is 5120x1440, but with "low resolution".

I am using one of two computers with the LG49. I have a 2017 13" MBPro. I was able to get the monitor to 5k using the USB-C cable, all the modifications listed here to the display file, AND with using ResolutionTab to choose that resolution.

I don't have the choice of selecting the 5120 resolution from the native display settings options for some reason. Although OSX is telling me its 30bit depth at 5120, the visual view of it on the display looks like its scaled, and not native. Happy at least that its working at 5k now though.

As for the MacPro trashcan that I have, it is Thunderbolt 2 and not 3, so I am struggling to get that to work. I even purchased the external chassis and GPU, which don't seem to work at all on the trashcan MBPro via a Thunderbolt 2 to USB-C (Thunderbolt 3) adapter.

So, if anyone can assist with either of these issues, that would be amazing. Thank you to all for helping!

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

I really do not think it, "went away after a few restarts". Please provide a screen shot of the 'Displays' system preference from a MBP 13", with an Intel graphics card, that has 5120x1440 and does not have "(low resolution)", next to it.

Hi there! I have 2017 MBP, but somehow it does not offer me a good looking 5120x1440 resolution on the external monitor (Samsung CRG9). Is your MBP upgraded with some Radeon GPU or it is with classical Intel Iris GPU?

In my case with Intel GPU the image quality at 5120x1440 is very bad - all the small letters are blurred and the monitor itself does not recognize that the signal is for 5120x1440.

All this types of software just upscale the resolution causing bad quality - this is not the solution I would say.

I have found interesting text on the LG web page (https://www.lg.com/ca_en/support/product-help/CT20098114-20151280078471-others) stating, that basically MBP can not output 5120x1440 resolution with Intel cards... would like to know more about this if possible, as currently I am struggling to connect my Samsung CRG9 to MBP13 2017

Exactly - thats why I am trying to find the way. I am also thinking of purchasing the MacbookPro 16 (the newest one) maybe it will offer the proper Resolution...but not sure. Otherwise I have tried Kensington Dock, which offers 5K output..but the image quality was still bad. Now I have the "Cable Matters" USB-C to DP adapter, which was advertised to handle up to 8K resolution...but result is bad as well. I suppose the video card in MBP13 is not powerful enough. Strange that #Apple tells that MBP13 2017 year can output the 5120x1440 resolution... especially when Apples adapters are limited to 3840x1080

Hey! Are you still unable to get the 5120x1440 on external monitor? I uppose you require not apple made adapter (apple adapters are limited to 3840x1080). I was planning to purchase the MBP16 tomorrow and connect it to samsung crg9 with 5120x1440....but now will wait for your response

VoV5, I have that monitor and a brand new MBP with the latest OS updates. It still won't do 5120x1440. For a machine of this cost, I would expect better than this - at least an acknowledgement from Apple that it's being addressed.

Thankfully Windows does, so when I'm not working, I switch. Honestly seeing less and less value in these machines, they look pretty, but better spec'd hardware and better driver support can be bought for less in PC land.

wow... good thing I read this, I was just thinking of getting the, Sonnet eGFX Breakaway Puck Radeon RX 570-S (Thunderbolt 3 only) that Apple approves on their website. I just don't understand how a powerful eGPU would not power a 5K monitor?

I love the monitor and it's decent in 3840 x1080, but we all know 5120 x 1440 would be stunning. So ******...

From what I been reading, it's all in the graphics card. If the MB Air has the entry level graphics card, it won't get 5120 x 1440. My Mac mini gets 4096 x 1152, which is decent. And of course, 3840 x 1080 which is decent. Good luck...if you get 5120 x 1440 let us know.

I was thinking of getting an external GPU for another $500 investment, but I haven't seen anyone getting results yet...

I'm thinking of buying the Sonnet eGFX Breakaway Puck Radeon RX 560 External GPU that Apple sells ($400).

But I don't know if it will run the LG 49 inch ultra wide monitor? And, will the noise make noise by running continually?

Thanks for posting!
