If you prioritize a large, ultrawide screen for an immersive gaming and productivity experience, the Dell Alienware AW3821DW could be worth the higher cost, though it won't excel in HDR gaming or media. For those who prefer a more affordable option suitable for both casual and competitive gaming with better response times and good color accuracy, the LG 27GP850 would be a solid choice, albeit with a smaller screen and slightly less suited for productivity tasks due to its traditional aspect ratio. Neither is ideal for serious HDR content creation, but both offer good overall performance for general use. Give Feedback

"In my opinion, the LG 27GP850 is the best in its class from the monitors I've tested, with the combination of great response times and a functional sRGB mode pushing it over the edge. It's generally worth the price premium and its overall balance of features with few weak areas makes it a monitor you won't be disappointed to have."
