If your focus is on productivity, especially with tasks involving digital photo editing, the LG DualUp with its unique aspect ratio and good color accuracy could be a strong choice, especially since it's more affordable. However, if you're looking for a monitor that excels in media consumption and casual gaming, with better contrast and HDR capabilities, the ViewSonic offers these features but at a higher price. The ViewSonic also has better brightness, making it more suitable for environments with varying lighting conditions. Keep in mind, for fast-paced competitive gaming, neither of these monitors is ideal due to their lower refresh rates and response times. Give Feedback
