If you're focused on competitive gaming and productivity, the CoolerMaster GP27U is a strong option with its higher refresh rate and variable refresh rate range which are beneficial for smooth and responsive gameplay. It also offers superb color accuracy for print photo editing. However, if you prioritize incredible contrast and color depth for HDR gaming and media consumption, the LG 27EP950 would be more suitable despite a lower refresh rate which isn't ideal for competitive gaming scenarios. The LG's OLED panel will deliver deeper blacks and more vivid colors but comes at a higher cost. Give Feedback
