The Lenovo IdeaCentre AIO 520S is as compact and lightweight as it is elegant. It features a widely adjustable, 23” full HD, borderless multitouch display and improved processing power. Add to that discrete graphics and immersive stereo sound, and this all-in-one is the perfect solution for no-hassle entertainment. The Lenovo IdeaCentre AIO 520S offers Advanced In-Cell Touch (AIT) technology. This drastically reduces the thickness of the screen, making it lighter, while offering a more vibrant and crisp image resolution.
