If you're a competitive gamer looking for the best response time and minimal ghosting, the Acer X27U (W-OLED) is an excellent choice, with a very high refresh rate perfect for fast-paced gaming. However, it's not as well-suited for productivity, and it's on the expensive side. On the other hand, the KTC M27T20 (VA MiniLED) offers very good performance for media consumption and digital photo editing due to its impressive color volume and contrast ratio at a lower price point. It's also suitable for casual gaming, but won't match the Acer in competitive gaming scenarios. Choose the Acer for top-tier gaming and the KTC for a well-rounded monitor that's easier on the wallet.

Notebook Check
Allen Ngo | March 2024
"The KTC M27T20 brings mini-LED and HDR1000 features to much more affordable price levels than before. It cuts some corners, however, and the settings require a lot of tuning for optimal colors and black levels."
