If you prioritize a wider, immersive display for media consumption and can invest more, the Gigabyte CO49DQ (QD-OLED) offers a larger screen and superior color performance, making it exceptional for both HDR gaming and professional photo editing. However, if you're looking for a solid all-around performer that balances cost and capabilities, the Cooler Master GZ2711 (W-OLED) would suit you well, especially if high refresh rates for competitive gaming and a good level of color accuracy for digital photo editing are important. Keep in mind that the Cooler Master has a smaller screen which might not be as immersive but comes at a more affordable price. Give Feedback
