AOC C24G1A 23.6" Curved FHD 165Hz Gaming Monitor vs LG 27GR93U-B 27" UltraGear 4K 144Hz IPS Gaming Monitor
The LG 27GR93U-B 27" UltraGear 4K 144Hz IPS Gaming Monitor is the better choice for most users, thanks to its stunning 3840 x 2160 resolution that brings games to life with incredible detail. In real-world use, the extra pixel density means sharper images, which is a game-changer for both gamers and creators alike. The AOC C24G1A 23.6" Curved FHD 165Hz Gaming Monitor is the budget option here, offering a competitive 165Hz refresh rate, perfect for fast-paced gaming. However, its lower resolution of 1920 x 1080 limits your experience, making it less ideal for multitasking or detailed visual work. So, if you crave immersive visuals, the LG is worth the upgrade in 2026.
