If you're a competitive gamer looking for smooth gameplay and higher refresh rates at a lower price, the Acer X27U is a strong option. However, if you prioritize higher resolution for sharper images and are engaged in print photo editing, despite its higher cost, the LG 27EQ850 may serve you better. Keep in mind, the Acer has better performance in fast-paced games due to its response time and range of refresh rates, while the LG excels in clarity and color for productivity and media. Neither is optimal for HDR gaming and media consumption due to limited brightness capabilities. Give Feedback
