If you're seeking a better price and a balance across various uses including productivity and casual gaming, the Cooler Master GZ2711 (W-OLED) is a strong choice with solid gaming performance and good color coverage for photo editing. For a more immersive gaming and media experience with a larger screen and wider aspect ratio, the Corsair 45WQHD240 (W-OLED) fits the bill, but it falls short in productivity and text clarity while commanding a higher price. Keep in mind the Corsair's larger size may be more impactful for media consumption, but it won't be as sharp for text due to its lower pixels per inch. Give Feedback
