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

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!!!!

Hi Alex, i won't upgrade my OS to 10.15 cause I'm using lot of 32-bit plugins...

What I'm using :

Razer core x

Radeon Vega 64 8gb (used)

Last, a LG 49WL95C-W original 5k DP cable...

The razer core x will have a 0.5m thunderbolt 3 cable, but i think its to short for me, so i bought a 2m long cable (*40Gbps Supports 100W Charging)

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'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?

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'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.

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

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!

All the solutions technically "work", however they are all unacceptable in my book. I have a crappy 600.00 laptop with the same video card that can support a 49" 5120x1400 resolution and looks great, but my 2300.00 mac mini can't? UNACCEPTABLE Apple. Fix the problem!!!!

10.15.4 does not fix the problem. Over the last 10 to 15 years I've spent close to a 1/2 of a million on apple products running a small business. The fact they can't fix this fairly straightforward issue really makes me start to rethink using apple products in general. The premium price model they have should come with better support than this.
