If you prioritize a large screen and an immersive experience, the AOC monitor's wider aspect ratio and larger size could be a better fit, especially for HDR gaming and media consumption. However, this comes with a higher price tag. On the other hand, the Cooler Master offers a more standard size and aspect ratio, which might be a more versatile and budget-friendly option, still excellent for gaming with good color accuracy for photo editing. It might not offer the same level of immersion as the AOC but is a strong contender for various uses at a more accessible price point. Give Feedback
