IPS technology, which is accurate across 178° presents a splendid quality in wide angles. Through the screen, everything is crisp and clear from any angle.

Superbly sleek

Picture, perfect

The zero-frame design lets the brilliant 4K2K Ultra HD images stand out and pop even more. When you put multiple S7’s side-by-side, this zero-frame design creates one almost-seamless image.
