About this deal
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. 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. 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. If I only used this monitor to view images, I’d probably run it at its full 4K resolution. But menus look too tiny and are very hard to read at that size. Scaling it somewhat smaller helps a lot. 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.

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. 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.] 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 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.While the monitor resolution is 4K, I get the best-looking images by scaling the resolution down slightly to 2560 x 1440. This also means that application menus are clear and easy to read. 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. It was a sad parting. When I upgraded my computer from a 2013 iMac to a 2017 27″ iMac, I also made the change from Thunderbolt 2 to Thunderbolt 3. 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.

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. This monitor has a maximum resolution of 3840 x 2160, making it 4K. It also has a refresh rate of 60Hz via all of its inputs, offers HDR 10, and is compliant with the VESA DisplayHDR 400 standard. This isn’t the greatest version of HDR, and you can certainly find greater dynamic range and higher peak brightness on higher-priced monitors, but if this is a monitor used mostly for regular computer work you won’t be using HDR much anyway.Assembly required attaching the stand and connecting the HDMI and power cables. The entire process took 15 minutes; I timed it. You’ll need a Philips screwdriver to attach the stand. However, even though the printed instructions are cryptic, you won’t have any problems assembling this.
