If you're a competitive gamer who also does digital photo editing, the Acer XB323U-GX offers a very high refresh rate which is great for smooth gameplay, along with strong color accuracy useful for photo work. However, the Dell Alienware AW3423DW, with its OLED technology, provides superior contrast and color vibrancy which makes it excellent for HDR gaming and media consumption, giving you a more immersive experience. Bear in mind that the Alienware's refresh rate, though good, isn't as high as the Acer's, which could be a deciding factor if you prioritize competitive gaming performance. Additionally, the Alienware's ultrawide screen enhances immersion and productivity but may not be supported by all games. Give Feedback
