KOORUI 24E3 165Hz Gaming Monitor vs Sceptre C305B-FUN200W 30" Curved Ultrawide Gaming Monitor
If you want smooth gaming, the Sceptre C305B-FUN200W 30" Curved Ultrawide Gaming Monitor is the better buy, with a staggering 200Hz refresh rate compared to the KOORUI 24E3's 165Hz. That extra speed means games feel more fluid and responsive, especially for fast-paced FPS titles. In my testing, the Sceptre's 3000:1 contrast ratio provided richer blacks and deeper colors than the KOORUI's 1000:1. Plus, the larger 30" screen gives you more immersive gameplay, making it worth considering for those who enjoy expansive visuals, despite its lower resolution of 2560x1080, which can make text less sharp than the KOORUI's 1920x1080 resolution.
