If you prioritize outstanding image clarity and color accuracy, especially for tasks like digital photo editing or HDR video editing, the CoolerMaster GP27U (IPS MiniLED) monitor with its higher resolution and strong HDR support would be a great choice. It's also suitable for casual gaming and offers a pleasing media consumption experience. However, if competitive gaming is your main focus and you're looking for better response times and higher refresh rates, the KTC G27P6 (W-OLED) with its impressive contrast and color depth might be more appealing, despite its lower resolution and potential burn-in risks associated with OLED panels. Keep in mind, though, that the KTC's performance in productivity and media consumption is not as optimal as the CoolerMaster's. Give Feedback
