If you prioritize a more immersive gaming and media experience and prefer an ultrawide screen with excellent contrast and vibrant colors, the Acer X34V with its OLED panel is a strong choice, especially considering it costs less. However, if sharper text, higher resolution, and a more color-accurate display for tasks like digital photo editing are more important to you, and you're willing to invest more, the Sony M9 with its 4K resolution and comprehensive color gamut support might be the better option. Keep in mind that despite its higher price, the Sony M9's smaller screen and traditional aspect ratio may not be as suited for an expansive gaming experience as the Acer X34V. Give Feedback
