AOC C24G1A 23.6" Curved FHD 165Hz Gaming Monitor vs Acer Nitro XV275K P5 27" 4K Mini-LED Dual-Mode Gaming Monitor
If you're looking for a gaming monitor that delivers performance without breaking the bank, the AOC C24G1A 23.6" Curved FHD 165Hz Gaming Monitor is the budget option that shines with its 165Hz refresh rate. On the flip side, the Acer Nitro XV275K P5 27" 4K Mini-LED Dual-Mode Gaming Monitor offers a stunning 3840 x 2160 resolution, perfect for those who crave crisp visuals. In my testing, the AOC's 165Hz refresh rate means ultra-smooth gameplay, making it a winner for competitive gamers. However, the Acer's 600 nits brightness and 27" display provide a more immersive experience, especially for content streaming and gaming in HDR. If you're aiming for a high-res display, the Acer's specs make it hard to resist in 2026.
