Our take

What it's like to live with

The LG UltraFine 4K Display is a purpose-built monitor designed primarily for Mac users who want a seamless plug-and-play experience alongside their MacBook, MacBook Pro, or MacBook Air. Featuring a 23.7-inch IPS panel with a 3840 x 2160 resolution, this display delivers crisp text, vivid colors, and sharp detail that make it ideal for creative professionals, writers, and anyone who spends long hours working on detailed documents, photos, or video content. The P3 wide color gamut ensures accurate, true-to-life color reproduction, which is especially valuable for photographers and video editors who rely on precise visual output for their work.

Connectivity is one of the standout strengths of this monitor, as it uses a single USB-C cable to simultaneously deliver video, data, and up to 85W of power to a connected laptop. This means users can charge their MacBook while using the display without needing a separate power adapter, reducing cable clutter on the desk. The inclusion of additional USB-C ports on the monitor itself also allows it to function as a hub, letting users connect peripherals like external drives, keyboards, or cameras directly through the display, which is a practical feature for anyone looking to simplify their desktop setup when using a laptop as their primary computer.

Beyond its technical specifications, the LG UltraFine 4K Display is built with an adjustable stand that allows for tilt and height customization, helping users find a comfortable ergonomic position for extended work sessions. Its slim bezels and minimalist design complement the aesthetic of modern laptop setups, making it a natural visual match for Apple hardware while still being compatible with other USB-C-enabled laptops and tablets. As a monitor within the laptop and tablet accessories category, it serves as an excellent secondary display for multitasking, extending screen real estate for professionals who need more room for spreadsheets, design software, or video timelines, all while maintaining a clean, cable-efficient desk setup.

The verdict

LG UltraFine 4K Display (24MD4KL)

The LG UltraFine 4K Display is a compelling choice for MacBook and MacBook Pro users who want a crisp, color-accurate secondary display with single-cable convenience. While it shines in the Apple ecosystem, Windows users may encounter more friction with drivers and brightness controls. For creative professionals already invested in Thunderbolt-equipped laptops, it remains a solid, if pricier, 4K accessory monitor.
