If you're a competitive gamer or a professional who needs high color accuracy for tasks like digital photo editing, the Acer X34V with its superior contrast and color volume could be well worth the investment. However, if casual gaming, general productivity, and saving money are your priorities, the LG 27GP850 will offer a very good gaming experience, satisfactory image clarity, and good text quality at a lower price. Although the Acer excels in HDR gaming and media, with better overall image quality and a wider color range, the LG can handle everyday tasks effectively. Choose the Acer for top-tier visuals and gaming performance or the LG for a solid all-around monitor that keeps your budget in check. Give Feedback

Tim Schiesser | May 2021
"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."
