If you're looking for a monitor that excels in competitive gaming with a higher refresh rate, the Acer XB323U-GX could be an excellent choice, although it's more expensive and not as well-suited for HDR gaming and media consumption. On the other hand, the CoolerMaster GP27U offers better value with superior image clarity, higher resolution, and impressive performance for HDR content, making it a strong contender for productivity and media consumption. However, its lower refresh rate might not be ideal if ultra-smooth gameplay is your top priority. The decision ultimately rests on whether competitive gaming or media and productivity features are more important to you. Give Feedback
