If competitive gaming is your priority and budget is a consideration, the Acer XB323U-GX with its high refresh rate and variable refresh rate technology can enhance your experience. However, the Asus PG34WCDM with its OLED panel provides superior contrast and color depth, which is excellent for HDR gaming and media consumption, but this comes at a higher price. For productivity, the Acer's larger screen size may be more suitable for multitasking, yet the Asus offers a wider, more immersive display due to its aspect ratio, which could be advantageous for certain professional and leisure activities. Both monitors have their strengths, so your decision should be guided by what you value more for your gaming, media, and productivity needs. Give Feedback
