Display
The display of the BLU S91 is one of its noteworthy components, featuring a 6.5-inch IPS LCD screen. With a screen-to-body ratio of approximately 81.1%, the phone offers ample viewing space for media consumption and browsing. The resolution stands at 720 x 1600 pixels with a 20:9 aspect ratio, which, combined with a pixel density of around 270 ppi, provides clear and vivid visuals, though it may not be as crisp as full HD displays, but it is adequate for most tasks.
