If you're a competitive gamer looking for a large, ultra-wide display with high responsiveness and variable refresh rate, the Acer Predator X45 (W-OLED) is a natural choice. Its large screen and high refresh rate make for an immersive gaming experience. However, it’s not the best for productivity due to its lower resolution and text quality. In contrast, the Asus PA27DCE (W-OLED) offers better clarity and higher resolution, making it suitable for detailed photo editing and enjoying high-resolution media, but it has lower refresh rates, which isn't ideal for fast-paced gaming. Consider the Asus if image quality in creative work and media consumption is your priority, despite being more expensive. Give Feedback
