If you're looking for a more affordable option that still offers a great gaming experience with a very high refresh rate and strong performance in fast-paced games, the AOC AG276QZD (W-OLED) is a solid choice. It has a high contrast ratio and is suitable for HDR gaming, but it may not be the best for productivity or media consumption due to its fair image clarity and smaller screen size. On the other hand, the AOC AG456UCZD (W-OLED) is a larger ultrawide monitor which can enhance immersion in games and can be better for multitasking during productivity work, but it comes at a higher cost. It also supports HDR gaming but details regarding its HDR peak brightness are unknown, which could affect HDR performance. Keep in mind, the AG456UCZD's larger size results in lower pixels per inch, which might affect text sharpness and overall image clarity. Give Feedback
