If budget is a concern and you engage in diverse tasks like digital photo editing and require an adjustable stand, the Acer XB323U-GX (IPS) offers a solid all-round performance at a lower cost. On the other hand, if you're focused on a top-notch gaming experience, especially for HDR gaming, and prefer larger and ultra-wide displays, the Corsair 45WQHD240 (W-OLED) offers superior contrast and response times suitable for intense gaming sessions, albeit at a higher price point. Keep in mind, though, the Corsair model may not be as well-suited for productivity due to its lack of an adjustable stand. Give Feedback
