If you're a competitive gamer looking for the best refresh rates and response times, and you're willing to invest in a premium experience, the Asus PG34WCDM with its very good refresh rate, best in class response time, and W-OLED panel might be the right choice. However, if you're focused on digital and print photo editing, prefer higher resolution, and want the best possible color accuracy on a larger color gamut, the KTC M27P20 Pro with its 4K resolution and excellent color performance offers a great value for an upper midrange price. The KTC is also more versatile for productivity, thanks to its higher resolution and better text clarity. In contrast, the Asus's ultrawide display with a 21:9 aspect ratio can be beneficial for immersive gaming and multitasking. Keep in mind that both monitors support HDR gaming and media consumption, but the Asus provides a more striking contrast with its OLED technology. 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."
