If you prioritize a larger screen size for an immersive gaming and media consumption experience, the AOC AG456UCZD with its 44.5-inch display offers that advantage, along with exceptional color depth for digital photo editing. However, it has poorer text clarity which might impact productivity tasks that involve reading or coding. On the other hand, the Asus PG34WCDM is slightly less expensive with a smaller 34-inch screen, better image clarity, and superior high dynamic range (HDR) peak brightness, making it more suitable for HDR gaming and video editing. Both monitors offer excellent refresh rates for smooth visuals in gaming. Choose the AOC for a larger display and photo editing, or the Asus for better HDR performance and a slight cost saving.
