The 87 cm long strip is not suitable for a 55-inch TV as it is significantly shorter than the recommended models for this screen size. The official Philips Hue Play Gradient Lightstrips for 55-inch TVs are around 212-216 cm long so that they can optimally illuminate the edge of the screen. The 87 cm long strip is designed for much smaller applications and is not sufficient for a 55-inch TV.
