LG 27GL83A-B 27" UltraGear QHD IPS Monitor vs Alienware AW2523HF 24.5" FHD 360Hz Gaming Monitor
When it comes to gaming monitors, the LG 27GL83A-B 27" UltraGear QHD IPS Monitor is the mid-range option, but its 2560 x 1440 resolution delivers stunning visuals. The Alienware AW2523HF 24.5" FHD 360Hz Gaming Monitor, on the other hand, shines with a blistering 360Hz refresh rate that makes fast-paced gaming feel incredibly smooth. In my testing, the LG monitor provides a sharp image with its 1ms response time, perfect for competitive gaming. However, if you're into titles like CS2 and Valorant, the Alienware's 0.5ms response time and ultra-high refresh rate make it hard to beat, especially for serious esports players in 2026. Key specs: Display: 27" vs 24.5" and Refresh: 144 Hz vs 360 Hz.
Why compare these? The LG 27GL83A-B 27" UltraGear QHD IPS Monitor (mid-range) and Alienware AW2523HF 24.5" FHD 360Hz Gaming Monitor (high-end) represent different approaches to monitors. While they may appeal to different budgets, many buyers consider both options. This 2026 comparison helps you decide if the differences justify the price gap.
