If you're a serious gamer seeking swift response times, high refresh rates, and excellent contrast, the AOC AG276QZD would be an excellent investment despite its higher cost. On the other hand, if you prioritize a wider screen for multitasking and general productivity without requiring the top-tier gaming features, the LG 34WQ73A offers a larger, ultrawide display at a more affordable price, although it won't match the AOC in gaming performance. Keep in mind the AOC's OLED panel also offers superior image quality, which is great for HDR content, but the LG's wider color coverage is better if you're into print photo editing. Give Feedback
