If deep blacks and vibrant colors for HDR gaming and media are important to you, the Acer X27U with its OLED panel is a strong choice despite its lower brightness and contrast in well-lit rooms. The 27-inch size also means higher sharpness and better ghosting control, which is great for immersive gaming. However, for extensive photo editing and print work where color accuracy across wider color gamuts is crucial, and for productivity tasks that benefit from more screen real estate, the larger 32-inch Acer XB323U-GX with excellent color coverage and a higher resolution might be preferable, assuming you're okay with spending more.
