If you're looking for top-notch image clarity and color accuracy for tasks like HDR video editing or print photo editing, the MSI MAG 321UPX's larger screen and higher resolution might justify its premium price. However, the Pixio PX277 OLED Max offers very similar performance in color depth and contrast, making it a cost-effective option especially if you are focusing on gaming and general media consumption. Both have excellent refresh rates and response times, ideal for immersive and responsive gaming, but the Pixio may offer better value if you can compromise on the screen size and pixel density.
