If competitive gaming is a priority, the Acer X34V with its wider screen, higher refresh rate, and variable refresh rate support would suit you well, but its larger size and lower resolution may not be ideal for productivity tasks. On the other hand, the LG 27EP950's higher resolution and smaller screen offer sharper images and better clarity for productivity and digital photo editing, alongside excellent color performance for HDR gaming and media. However, its lower refresh rate and absence of variable refresh rate support make it less optimal for competitive gaming. The Acer is a better value for those focused on gaming and entertainment, while the LG is geared towards professionals in digital content creation needing precise color accuracy. Give Feedback
