With a 5.0-inch IPS LCD screen, the Noir S4 delivers a decent visual experience. The display resolution of 720 x 1280 pixels results in a pixel density of approximately 294 ppi, which, at the time of its release, provided clear and crisp visuals. Although the screen-to-body ratio is about 65.8%, which is relatively low by today's standards, it offered satisfactory viewing with good color reproduction, suitable for everyday tasks and media consumption.
