If you prioritize a high contrast ratio and excellent color performance for immersive gaming and media consumption, the Acer X34V is a strong choice, particularly for HDR content, and it comes at a lower price. On the other hand, the Dell Alienware AW3821DW offers a wider screen with a slightly higher resolution which can be beneficial for productivity tasks, but it isn't as suitable for HDR gaming or media. Choose Acer for a better gaming experience and cost savings, or go for Dell if productivity and screen real estate are your main priorities despite its higher cost. Give Feedback
