If you prioritize competitive gaming and have a higher budget, the AOC AG456UCZD with its larger screen and superior refresh rate would give you an edge with smooth gameplay. However, for a focus on productivity, digital photo editing, and enjoying high-resolution media, the KTC M27P20 Pro offers excellent image quality with sharp details at a lower cost. Neither is ideal for casual gaming, but in terms of overall image clarity and color accuracy for professional creative work, the KTC might be the better investment. Choose the AOC for gaming-oriented needs and willingness to invest more, or the KTC for a balance between cost and performance in professional and media applications. Give Feedback

How the AOC AG456UCZD (W-OLED) and the KTC M27P20 Pro (IPS MiniLED) compare to other monitors
"Gaming and HDR are the two target uses for this screen, and it does generally very well in both. For gaming there are good response times, a single overdrive mode experience for VRR, super low input lag and solid support for latest gen consoles too. The moderately high 160Hz refresh rate provides good motion clarity, and is a nice combination with the high 4K resolution that provides a sharp and crisp image."
