The pixel density of 109 ppi provides adequately crisp text without requiring scaling, though pixel edges may become noticeable when sitting close or working with fine content. With a brightness level of 300 nits, this monitor may appear dim in bright office settings, making it less suitable for environments with strong ambient light.
