Acer SB220Q bi 21.5" FHD IPS Monitor vs LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor
The Acer SB220Q bi 21.5" FHD IPS Monitor is the budget option here, while the LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor takes the flagship crown with its unique design and premium specs. The key difference? The LG's resolution of 2560 x 2880 packs in way more detail than Acer's 1920 x 1080, making it a game changer for creators and multitaskers alike. In real-world usage, that means the LG DualUp gives you the vertical workspace of two 21.5-inch monitors without the bezel gap. While the Acer's 75Hz refresh rate makes it decent for gaming, the LG’s color accuracy covering 98% DCI-P3 is a massive advantage for photography and design work.
