The Dell S2721QS offers a higher screen resolution which is better for productivity and media consumption due to its sharper image quality, and it's also well-suited for digital photo editing. If gaming is your priority, especially competitive gaming, the LG 27GP850 has a higher refresh rate, resulting in smoother motion, and comes with variable refresh rate support and less ghosting, making it ideal for fast-paced games. However, the LG's resolution is lower, which might affect the sharpness of the image for productivity tasks. Both monitors have their strengths, so your choice should be guided by whether you prioritize work and media viewing (Dell) or gaming performance (LG). Give Feedback

"The Dell S2721QS 4K monitor brings IPS-level colors and some handy features, like a versatile stand with height adjustments and picture-in-picture for connecting dual systems. But don’t get it for HDR."

"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."
