Dell UltraSharp U2723QE 27" 4K USB-C Hub Monitor vs LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor
Get the Dell UltraSharp U2723QE 27" 4K USB-C Hub Monitor unless you need a unique aspect ratio. The numbers: 3840 x 2160 resolution crushes the LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor's 2560 x 2880. In real-world use, that extra pixel count means sharper images and more screen real estate for multitasking. While both monitors offer USB-C with 90W charging, the Dell's 400 nits brightness versus the LG's 300 nits provides a clearer and more vibrant display. The Dell's IPS Black technology also delivers a 2,000:1 contrast ratio, making it ideal for creators and professionals who demand precision in color accuracy and detail. That said, if you value vertical space, the LG's 16:18 aspect ratio mimics having two monitors stacked without the bezel gap, which is a game changer for productivity enthusiasts in 2026.
