Longer notes from the same comments we summarized above.

What people reported

Owners consistently highlight the LG DualUp's unique 16:18 aspect ratio as a significant advantage for productivity. Many describe it as being similar to two 16:9 monitors stacked vertically, which saves desk space and enhances vertical screen real estate. This makes it particularly appealing for software developers, marketers, and anyone working with spreadsheets or extensive documents. Users appreciate being able to open multiple editor tabs or browser windows side-by-side without needing virtual desktops. For example, one user found it "great editing videos in adobe premiere and working on code for websites." Owners also widely praise the ergonomic arm stand, describing it as "amazing and so easy to set up." The monitor offers versatile connectivity, including USB-C, and features a built-in KVM switch, which is a significant plus for those using multiple computers. Picture-by-Picture (PBP) mode is available, and it works well with an M1 Mac Air.

Problems people mention

One recurring point is the monitor's 60Hz refresh rate, which some users find limiting, especially for gaming. An owner noted that Windows HDR functionality causes desaturation, making it "unusable" without a fix from Microsoft. While generally positive, at least one owner reported experiencing "technical faults every couple months." A minor but frustrating issue for some is the difficulty in removing the stand cover after installation.

Where owners disagree

There isn't significant disagreement among owners regarding the monitor's core purpose or performance. Some discussion appeared around its pixel density (PPI), with minor variations in estimations (e.g., 108ppi to 140ppi), though it's generally considered to have a clear display. Owners largely agree on the monitor's strengths and target audience, with most comments focusing on specific use cases and trade-offs rather than conflicting experiences.

Who it's for

The LG DualUp 28MQ780-B is best suited for professionals focused on productivity, such as software developers, video editors, and those who need ample vertical screen space for multitasking. It is explicitly not recommended for avid gamers due to its 60Hz refresh rate. People looking to save desk space while maintaining significant screen real estate will find its unique form factor highly beneficial.
