SAMSUNG Odyssey G55A 32" Curved WQHD Gaming Monitor vs LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor
The SAMSUNG Odyssey G55A 32" Curved WQHD Gaming Monitor crushes the LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor for gaming, boasting a staggering 165Hz refresh rate versus just 60Hz. This means if you're into fast-paced gaming, the Odyssey G55A is the no-brainer choice, delivering smoother and more responsive visuals. In my testing, the 32" Odyssey's aggressive 1000R curvature and WQHD resolution enhance immersion significantly, making it feel like you're actually in the game. On the flip side, the LG DualUp is an intriguing flagship with a unique aspect ratio that offers vertical workspace, but its limited refresh rate makes it less ideal for gaming enthusiasts. If you're focused on productivity, the LG might have its perks, but for gaming, the numbers clearly favor Samsung.
