If you prioritize competitive gaming with faster response times and don't mind a lower resolution, the Cooler Master GZ2711 (W-OLED) is an excellent choice but it may fall short in productivity tasks due to its lower resolution and text clarity. Conversely, the KTC M27P20 Pro (IPS MiniLED), while less expensive, offers higher resolution and image clarity which makes it superior for productivity and media consumption, but its slower response time might not be optimal for high-level competitive gaming. Both monitors are capable of HDR gaming and media, but the KTC offers better brightness, making HDR content pop more. Give Feedback

TFT Central
Simon Baker | January 2023
"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."
