LG announces first OLED 4K UltraFine 31.5-inch display

LG is starting to use OLED panels in its UltraFine monitor line, with the first model having a 31.5-inch 4K display with a 99% P3 gamut and Adobe RGB color accuracy.

The latest LG UltraFine display revealed at CES 2021 uses USB-C, Display Port and HDMI for video connection. Color accuracy and gamut are in line with Apple's color ratings for the iPhone and iPad.

The eight million pixels in the 3840x2160 4K display can be individually dimmed, with the unit providing a 1,000,000-to-1 contrast ratio, according to LG.

The LG UltraFine Pro has a 90W USB-C PD port, two DisplayPorts, one HDMI port, three USB-A ports, a USB-B port, and headphone jack. It isn't clear if a single USB-C cable will also carry data for the USB-A ports, or if the USB-B port on the display is only required for HDMI or DisplayPort connections.

Users can also leverage the built-in KVM functionality to connect one monitor, keyboard, and mouse to multiple computing devices.

DisplayPort, HDMI, and USB ports for several connection options DisplayPort, HDMI, and USB ports for several connection options

You'll be able to chain displays together using the multiple port options, though you'll still be limited to one monitor when using an M1-based Mac.

LG has not announced a release window or pricing for the LG UltraFine Pro.

Hopefully this is the display on the next iMac. I have an Eizo at this size on my desk and it is great for my photography & design work.

Some of the technology in this display looks interesting, but this specific model is inferior to the 27" iMac display in resolution and gamut.

I am a long time fan of Eizo displays and use one on my Mac Pro and another recent Eizo purchase for the recently purchased Mac Mini (2018). They do displays/monitors very well IMHO.

I wish Apple would bring back an updated refresh of its 27" Thunderbolt monitor.  I have two of them connected to my iMac here at the office, and another one connected to my 2020 iMac at home and enjoy them immensely.  Sure, there are better-quality monitors out there now considering how old the Apple's TB monitors are, but they work perfectly and (as important) I like the styling.

LG's screen quality hasn't really been an issue - the problem is (and you'll find an utterly breath taking number of MacBook Pro users complaining about this) - their top of the line displays seem to have significant issues. You may recall an earlier issue with malfunctions if the display was in the proximity to a WiFi basestation, but even after that was fixed the displays still have issues with crashing Macs or software (such as the Adobe Suite), and other problems on wake: such as not waking up, waking up very slowly, or waking up with visual artefacts.

Apple would do well making their usual all-in-one displays again. (i.e. The XDR doesn't contain speakers, facetime camera, microphones, usb hubs etc.)
