ASUS ProArt Display PA278QV 27" WQHD Monitor vs LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor
The ASUS ProArt Display PA278QV 27" WQHD Monitor is the entry-level option, but it shines with its factory calibration, delivering a Delta E < 2 for remarkable color accuracy. However, if you're looking for a flagship experience, the LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor has a unique vertical design that mimics two monitors stacked, providing a total resolution of 2560 x 2880. In my testing, the ASUS display’s 75Hz refresh rate offers a smoother experience compared to standard 60Hz monitors, making it a solid pick for office work. On the flip side, the LG model's USB-C connectivity with 90W Power Delivery is a game-changer for modern laptops, making it easy to connect and charge simultaneously, which is a huge perk for creators in 2026 who need efficiency and flexibility on their desks.
