If you're looking for an immersive, ultra-wide display with top-notch contrast and are willing to invest more, the Acer Predator X45 (W-OLED) is an excellent choice for HDR gaming and media consumption. However, its text clarity and image sharpness aren't as good as other options. On the other hand, the KTC M27P20 Pro (IPS MiniLED) offers a sharp, high-resolution experience at a better price point, making it ideal for productivity, digital photo editing, and competitive gaming. While it's great for media consumption too, the Acer might still surpass it in overall visual impact due to the 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."
