If you prioritize high-resolution productivity and casual gaming, the CoolerMaster GP27U is a strong choice, offering good color accuracy for print photo editing and quality HDR gaming. It's more budget-friendly as well. However, for an immersive gaming and media experience with superior contrast and wide viewing angles, the LG 34GS95QE's curved ultrawide screen might be worth the higher cost. This monitor shines in competitive gaming due to its higher refresh rate, though it's less suitable for color-critical work like digital photo editing due to its limited brightness and color volume.
