Lenovo might have the most concept devices of any company at CES 2026, but the wildest and most interesting one is almost certainly the Legion Pro Rollable which features a 16-inch flexible display that can expand to not one but two different sizes.To make the Legion Pro Rollable, Lenovo started out with a standard Legion Pro 7i and kept the bottom half including all of its ports and support for an RTX 5090 GPU. But then the company went a bit crazy: Instead of replacing the notebook's original 16-inch OLED screen with a rollable variant that extends upwards like the Thinkbook Plus Gen 6 from 2025, Lenovo opted for one that expands outwards to either 21.5 inches or 23.8 inches This means instead of being restricted to a standard 16:10 aspect ratio, you also have the choice of 21:9 or an ultra-wide 24:9 with just the touch of a button. Or more like two buttons because to widen or shrink its display, you need to press FN plus one of its arrow keys.
