Transform Your Old Smartphone into a Vertical Digital Signage Display

In today’s fast-paced retail and hospitality industries, attention-grabbing visuals are essential. What if you could repurpose an old iPhone—or even an Android phone—into a sleek, vertical digital signage system? With the right tools, you can do exactly that, breathing new life into unused devices while saving on costly hardware.

iPhone Vertical Mirror to TV

Vertical displays are becoming increasingly popular for advertisements and information boards. By rotating your TV 90 degrees, you can mimic the look of professional signage systems. The challenge? Getting your iPhone content to fill the entire screen without black borders.

How to Let iPhone Mirror to TV

Apple’s Lightning-to-AV adapter can mirror your iPhone’s display to a TV. However, when used in vertical orientation, you’ll encounter large black bars on the sides. This is because Apple’s mirroring system maintains a fixed aspect ratio, even when the TV is rotated, making it unsuitable for true full-screen vertical signage.

Applications of iPhone Vertical Mirror

Full-screen vertical mirroring opens up a range of possibilities:

Menu boards in cafes and restaurants

Event schedules in hotels or conference venues

Product promotions in retail spaces

Information displays in reception areas

iPhone & iPad Monitor Ratio Issues

iPhones and iPads have different native aspect ratios compared to most TVs. This mismatch often leads to scaling problems when using standard adapters. The FEBON solution ensures the image is properly adjusted for vertical display without distortion or unused screen space.
