If budget is a concern and you require a high-resolution monitor for productivity tasks that also offers a good gaming and media viewing experience, the CoolerMaster GP27U (IPS MiniLED) would serve you well. However, if you are willing to invest more for an immersive gaming and media experience thanks to its superior contrast and wider color gamut, consider the Gigabyte CO49DQ (QD-OLED), keeping in mind its larger screen may not be as suitable for traditional productivity tasks due to its ultra-wide aspect ratio.
