If you prioritize a larger, ultrawide screen for an immersive experience in gaming and media, with the benefit of an adjustable stand and higher brightness, the Acer Predator X45 (W-OLED) is a strong choice despite its premium price. However, if you're looking for a monitor that's excellent for competitive gaming due to its lower total response time, preserves good text quality, and at a significantly lower cost, the Corsair Xeneon 27QHD240 (W-OLED) would be more suitable. Keep in mind, for tasks requiring color accuracy for print, the Acer has a slight advantage. Give Feedback
