LG 27GR93U-B 27" UltraGear 4K 144Hz IPS Gaming Monitor vs LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor
The LG 27GR93U-B 27" UltraGear 4K 144Hz IPS Gaming Monitor is the better choice for gaming, boasting a blistering 144Hz refresh rate compared to the LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor's 60Hz. This means smoother gameplay and less motion blur, essential for competitive gaming. In real-world testing, the UltraGear's 3840 x 2160 resolution delivers stunning visuals, making every detail pop. Meanwhile, the DualUp offers a unique 16:18 aspect ratio, perfect for multitasking and creative work, but its 2560 x 2880 resolution simply can't match the UltraGear's gaming prowess.
