For all my external storage, a TB 3 to TB 2 adapter solved the problem. But, not for my trusty Apple Cinema Display. While it still worked perfectly after all these many years, it did not work with my Thunderbolt 3 iMac. Your sense of color may be different than mine, which is fine. There are several controls you can adjust to make this look the way you want. This calibration works the same as every other Mac-compatible monitor, which is what I would expect, except that you adjust the monitor using the toggle switch on the monitor itself, not software controls. I’ve been using this monitor for a year-and-a-half and I’m still very happy with it. It’s been problem-free the entire time. But I’ve discovered two quirks you should know about: The stand uses a wide arched foot that provides enough desk space immediately in front of the monitor to accommodate your keyboard when not in use, or make space for other desk items.

The only disadvantages to this monitor is that it connects via HDMI, which requires a converter cable for all iMacs, and all adjustments are made using a multi-purpose toggle switch at the bottom center of the bezel. I like this monitor. I don’t play games, so the refresh rate is fine. The colors are lovely. The resolution is crisp and shows me I need to improve my ability to focus an image. It can also upscale regular SDR (standard dynamic range) content into HDR, using an algorithm to improve tone mapping and luminance. It’s not true HDR, but a nice feature to have nonetheless. When you first turn your Mac on, the monitor does not turn on. The power switch is located on the underside of the case, immediately under the LG logo. The monitor has a pair of 5W speakers, and while LG boasts of its MAXX Audio technology, sound really isn’t the strong point here. It’s acceptable for general computer notifications and occasional radio and podcast listening, but if you want to play music or watch movies and TV you are much better off connecting the monitor, or your computer, to a separate speaker or audio system.

LG makes lovely display panels. Colors are clean, resolution is crisp, the image holds up extremely well, even when compared to the 27″ iMac it is sitting next to. In fact, I ran the Apple Display calibration software when I first connected the display. It was right on, no adjustments were needed. The total image area is 3840 x 2160 pixels, which equals a UHD display. However, it defaults to Retina Display behavior which means that it changes the screen resolution to 144 ppt, then pixel doubles a 1920 x 1080 image. This makes text much easier to read, without, as far as I can tell, damaging image quality. In addition to changing settings using the on-screen monitor controls – which can’t be screen captured, or I would show them to you – you can also adjust and calibrate the monitor using System Preferences > Display > Color.

The default settings at power on are pretty near perfect, I just turned the brightness down a bit because my editing suite is pretty dim. So, I needed to get a new monitor. After extensive online research it came down to the Apple / LG UltraFine 4K Display, sold by Apple, and the LG 27″ UHD 4K Display sold by a variety of outlets. NOTE: One of my favorites is “Return to Initial Settings” which allows you to recover in the event you’ve so totally confused this monitor that nothing looks right. The stand is both curved and wide, running about 2/3 the width of the entire display. While stable, the stand makes it awkward for the monitor to share space with other devices on a desk. However, when powered on, the stand essentially recedes into invisibility, so that all you are looking at is a lovely image. For most users, these ports should give them everything they need. We connected a MacMini using the USB-C port and a couple of game consoles via HDMI. And because the USB-C port carries power as well as video and audio, the monitor can be used to charge a MacBook (or other USB-C laptop) while also acting as an external screen.

We have owned this monitor for around a year and have used it for work, gaming and TV/movie-streaming. Our working-from-home situation required a 27-inch display that would work with a MacBook (and latterly a Mac Mini) in a bedroom desk setup, but also provide a good gaming experience with a PlayStation 4 and Xbox One X, and stream 4K content from the likes of Netflix and Prime Video. UPDATED Nov. 28, 2020, with tips I’ve learned after using this monitor for a year and half. They are posted at the end. Also, read my product review disclosure statement.] Another thing I really like about this monitor is that it runs cool. It doesn’t get hot and it doesn’t radiate heat. In summer, in LA, I appreciate that.
