LG UltraFine 6K Display (32U990A) Review

With Apple’s discontinuation of the Pro Display XDR earlier this year, Mac users looking for a larger, high-resolution display suddenly found themselves with fewer options in the market. Apple’s current display lineup now includes its 27-inch Studio Display and ‌Studio Display‌ XDR, both of which offer excellent picture quality and tight macOS integration, but neither offers the larger 32-inch form factor that some users prefer.

LG’s UltraFine 6K Display (32U990A) helps fill this gap. The display, which was revealed in January 2025 but only launched last October, features a 32-inch 6K Nano IPS Black panel, Thunderbolt 5 connectivity, and a more Apple-inspired design than previous UltraFine displays. After using it for several weeks in my daily setup, I found it to be a worthwhile alternative to Apple’s own displays, albeit with some compromises.

The first thing that stands out about the UltraFine 6K is simply the workspace it offers. Compared to Apple’s 27-inch displays and my trusty 27-inch UltraFine 5K displays that have anchored my workspace for nearly a decade, the extra screen area is immediately noticeable. Multiple apps can sit side-by-side in large windows without feeling cramped to support my typical “command center” view of our editorial operations, while creative apps that need the canvas for themselves benefit from the extra space for toolbars and timelines.

Unlike many larger displays, the UltraFine 6K doesn’t compromise on sharpness. The 6144 x 3456 resolution delivers a true Retina experience, with crisp text and interface elements sized appropriately for the typical viewing distance. This is one of the screen’s biggest advantages over most monitors in this size class that only offer 4K resolution. While these displays can often produce a similarly sized desktop through scaling, the result sometimes lacks a bit of sharpness while the UltraFine 6K looks completely native due to its higher pixel density.

The UltraFine 6K also pairs well with Apple’s latest Macs thanks to support for Thunderbolt 5. Using a MacBook Pro, a single cable handles display output, charging, and connected accessories, and you can even daisy chain multiple displays over a single connection. DisplayPort 2.1, HDMI 2.1, and non-Thunderbolt USB-C ports on the display provide additional display connectivity options, as well as downstream Thunderbolt 5 port support to support daisy chain configurations and a pair of upstream USB-C ports for hub functionality.

LG includes up to 96 watts of power delivery into the display, making it easy to keep a 16-inch ‌MacBook Pro‌ charged throughout the day and relatively quickly recharging a depleted ‌MacBook Pro‌ when plugging in the display.

Day-to-day reliability was excellent in testing. The monitor consistently woke up from sleep mode without issue, display scaling options appeared correctly in macOS, and there were none of the connection quirks that sometimes plague third-party displays. Although this may seem like a small detail, smooth operation remains one of the most important qualities for a monitor aimed primarily at Mac users.

LG has also made significant improvements to the industrial design of its UltraFine line. Older UltraFine displays were known for their Mac compatibility, but they often seemed more utilitarian than high-end. The 32U990A adopts a sleeker aesthetic with slim bezels and a more refined rear case that doesn’t look out of place next to a Mac Studio or ‌MacBook Pro‌. A wide foot provides stability, as does a wide vertical support arm that features a discreet silver color on the front but dark blue ribbed plastic on the back to provide a bit of visual interest if the screen is used in an environment where the rear is visible.

Ports and a joystick button for controlling display settings are hidden on the back of the screen, and there are no distracting pulsing LEDs to light up a dark room when the screen is asleep.

The included stand offers height, tilt, swivel, and swivel adjustments, providing much more flexibility than Apple’s standard display setups to help you place the screen in the right ergonomic position.

The image quality is generally excellent. Colors appear vibrant and accurate, and the Nano IPS Black panel provides solid contrast. And of course, 6K resolution provides the sharpness and clarity many users are looking for.

The matte finish minimizes reflections well, especially in brighter environments or near windows. Apple’s glossy displays still offer a slightly more vibrant appearance, but the trade-off may be worth it for users who work in rooms with lots of ambient light.

LG touts the UltraFine 6K’s ability to work with macOS keyboard shortcuts for brightness and volume adjustments, although it’s not fully integrated into the macOS experience. Unlike my older UltraFine 5K displays which integrated seamlessly with the built-in macOS functionality for these shortcuts, the UltraFine 6K requires a separate LG Switch app to enable these keyboard shortcuts and they are separate from macOS-level adjustments while using the same keys, which makes things less seamless than I would like. Simply put, things can be tricky when using multiple screens and audio output options.

There are a few other areas where Apple displays continue to maintain an advantage. The ‌Studio Display‌ XDR delivers significantly brighter HDR highlights and overall more impressive HDR performance, thanks to its advanced backlight technology. Users who work a lot with HDR video content will still benefit from Apple’s high-end display. The UltraFine 6K is also limited to a 60Hz refresh rate. For productivity work, this isn’t a major concern, but users who spend a large portion of their day on ProMotion-equipped Macs may notice the difference when scrolling or performing other actions that result in rapid on-screen movement.

These limitations seem relatively minor, however, when considered in the context of the entire UltraFine 6K package, especially considering the price difference compared to the ‌Studio Display‌ XDR. The main appeal of the UltraFine 6K isn’t the HDR performance or refresh rate. It’s the combination of a large 32-inch panel, Retina resolution, Thunderbolt 5 connectivity, and solid Mac compatibility.

The UltraFine 6K delivers the sharpness and ease of use Apple users expect, while offering significantly more screen real estate than Apple’s current display lineup. The result is a display that seems almost purpose-built for Mac users and stands out as one of the most powerful high-end monitor options currently available for Mac. The LG UltraFine 6K 32U990A is normally priced at $1,999.99, but LG is currently offering a $700 savings on the display, bringing it down to $1,299.99.
