Lg Ultrafine 4k Monitor Resolution And Scale Settings For Mac

 



LG Ultrafine 4k monitor resolution and scale settings for Mac I tried the LG Ultrafine 4k monitor at Apple store yesterday. I find that the default resolution and scale settings uses 1440p resolution. Using the highest settings made the UI and texts appear so tiny. UHD 4K resolution displays breathtaking clarity and fine detail with four times the resolution of Full HD. Plus this monitor is designed to work with compatible calibration devices that ensure precise adjustments of color, brightness and more. The UltraFine 4K Display features a 23.7-inch IPS panel, P3 wide colour gamut and 500 cd/m² of brightness. And with over 8 million pixels, it has four times more than a typical 1080p HD display.

Back in December I wrote this article about how Apple no longer sell any displays. Since then Apple have started selling a nice LG display that works with MacBooks. This has been designed in conjunction with Apple so that you can control the display’s volume and brightness from the Apple computer. It essentially functions as an Apple display but with an LG badge. On their website Apple describe it as: “A perfect complement to your MacBook or MacBook Pro.” The monitor plugs into the USB-C port on the new MacBooks. But the new LG monitors that Apple are selling don’t plug directly into to older Macs. What Apple’s website doesn’t say is that they sell an adapter that will allow this monitor to work with some non USB-C Macs.

UPDATE January 2019: Please disregard this article. The USB-C to Thunderbolt Cable is not as functional as it sounds. Foe example it would not let me hook a thunderbolt display to the USB-C port on my new 2018 Mac Mini, despite it’s claims of being bi-directional. So if you are thinking of buying the thunderbolt to USC-C adapter go into an Apple store first and make sure it will do what you want it to do.

LG recently debuted a new 32UL950 32-inch UltraFine 4K display, but this latest model, priced at $1300 wasn't designed in partnership with Apple.

The new MacBooks are equipped with Thunderbolt 3 which uses a USB-C connector. The older Thunderbolt 2 used the same connector as the old Apple Display Connectors. This can get a little confusing. The bottom line is that the new LG monitors that Apple are selling don’t plug directly into to older Thunderbolt 2 Macs.

But Apple do sell a Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter to plug older Thunderbolt 2 devices into the new Thunderbolt 3 MacBooks. Apple’s new adapter is so clever that it works both ways! It will also allow you to connect a Thunderbolt 3 device such as the LG display into an older Thunderbolt 2 Mac such as a Mac Mini or older MacBook. This is genius! Most adapters only work one way.

Even if you can get it plugged in physically, not all Macs with Thunderbolt 2 have the graphics capability to drive the higher resolution Thunderbolt 3 display.

This page from Apple describes which computers can drive the LG 4K display.

This page from Apple describes which computers can drive the LG 5K display.

Notice that the Mac Mini (2014) is NOT compatible with the LG 4K display, but it is compatible with the LG 5K display.
