If premium image quality and high dynamic range are top priorities for you, and you are okay with a higher price, the Asus W-OLED monitor is an excellent choice, especially for HDR gaming and media consumption. Its superior contrast and color accuracy make it ideal for digital photo editing as well. However, if you are focused on competitive gaming and are looking for a budget-friendlier option, the ViewSonic IPS monitor offers a fast refresh rate and good performance for this use, but it won't deliver the same level of image clarity and color performance for other activities like HDR content viewing.
