LG has updated its UltraFine lineup of displays, which are aimed especially at computers made by Apple. The entry-level UltraFine 4K has received a larger screen, whereas the more advanced UltraFine 5K has gained a USB Type-C port. Both monitors are now compatible with Macs as well as the latest iPad Pro tablets, enabling owners of the latter to use them as desktops.

The new entry-level LG UltraFine 4K monitor is now based on a 23.7-inch IPS panel featuring a 3840×2160 resolution, 500 nits brightness, a 60 Hz refresh rate, and the usual 178°/178° horizontal/vertical viewing angles. The display comes with integrated stereo speakers, and an built-in PSU. When compared to the original UltraFine 4K introduced in 2016, the new LCD is bigger, but its resolution is the same, and as a result the pixel density got lower.

The larger LG UltraFine 5K display uses a 27-inch IPS panel featuring a 5120×2880, 500 nits brightness, a 60 Hz refresh rate, and 178°/178° horizontal/vertical viewing angles. The new LCD is equipped with a webcam, built-in stereo speakers and a microphone, as well as an integrated power supply. In an important change, this model now no longer requires a Thunderbolt 3 connection; the monitor can be used with a USB-C port as well (with DP alt mode), making it compatible with a wider range of devices, and likely indicating that LG has upgraded to Intel's Titan Ridge TB3 controller.

As these monitors are primarily meant to be used with Apple products, LG’s UltraFine monitors only support the P3 color gamut – where Apple offers very robust OS-level support – and are compatible with Apple’s latest Macs as well as 2019 iPad Pro tablets, making this the first time these displays have worked with an iPad. Both displays can connect to hosts using a Thunberbolt 3 or a USB 3.1 Gen 1 Type-C ports that can deliver up to 85 W or 94 W of power to a laptop or a tablet.

    Hmm, I guess LG cut the resolution when going from 22" (4096 x 2304) to 24" (3840 x 2160).

    Doubt you will notice the difference between 22" (4096x2304) and 24" (3840x2160) anyway. Not at those display sizes.

    Maybve? But it appears it has to be Thunderbolt 3 and not just USB-C with DisplayPort:

    It can also work with Thunderbolt 2 to 3 converters (there's dispute over if it works with full control):

    What is the color space these monitors cover? Not unimportant if you want to use them for graphics or editing jobs.

    Like it says, Apple's Display P3: https://en.wikipedia.org/wiki/DCI-P3#Display_P3
    Seems like DCI-P3 accommodating for the fact you're probably using non-colour-managed apps, where being closer to sRGB it's likely to work better than DCI-P3, while still having the same range.

    Of course, *how* much of that space is an reasonable question, and oddly not covered here. I had to go hunting. On https://www.lg.com/uk/monitors/lg-27MD5KA it says "99% P3".

    The 5K monitors has always had a usb-c port. TB3 uses usb-c. Not sure where the author got the idea that the 5K monitors works without TB3. The manual clearly says connect to a TB3 host. Also usb-c DP alt-mode lacks the bandwidth for 5K.
  • Alistair - Friday, August 2, 2019 - link

    it was TB3 only, now it supports regular USB-C with one of the ports so you can connect your iPad
  • timecop1818 - Friday, August 2, 2019 - link

    DisplayPort 1.4 can definitely do 5K. Nothing is preventing usb-c displayport alternate mode from passing DP1.4 over it.

    What do you mean by "works with an iPad"? As in displays iPad contents onscreen...?
  • RSAUser - Tuesday, August 6, 2019 - link

    It would use a USB C to USB C cable, and what is displayed depends on what app you're in. Most mirror while some use it as an extension, e.g. Lightroom shows the edited photo on the external display.
