Acer Nitro XV275K P5 27" 4K Mini-LED Dual-Mode Gaming Monitor vs LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor
Get the Acer Nitro XV275K P5 27" 4K Mini-LED Dual-Mode Gaming Monitor unless you need professional color accuracy. The numbers: 160Hz refresh rate crushes the LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor's 60Hz, making it a no-brainer for gaming in 2026. In real-world use, that 160Hz means smoother gameplay, reducing motion blur during fast action. On the flip side, the LG DualUp is a flagship choice with an impressive 98% DCI-P3 color coverage, great for photographers, but it sacrifices refresh rate for that stunning vertical workspace of 2560 x 2880 pixels. What matters most here is how you plan to use it.
