The Lenovo IdeaPad U400 is a high-end 14" ultraportable laptop similar to the 13.3" Lenovo IdeaPad U300. Aside from just display size, the two differ in a few essential ways, namely: discrete AMD Radeon 6470M graphics rather than integrated Intel HD, an optical drive (a slot-loading DVD-RW) and stereo speakers with SRS Premium Surround Sound. Otherwise, the U400 and U300 sport the same features including 2nd generation Intel Core i processor options and Intel Wireless Display technology.
The IdeaPad U400's AMD Radeon 6470M graphics provide it not only with high definition video playback but also DirectX 11-level gaming capability. Its stereo speakers' SRS Premium Surround Sound technology provides the IdeaPad U400 with enhanced sound capability including simulated surround sound and enhanced bass. Meanwhile, the IdeaPad U400's Intel Wireless Display (WiDi) technology allows it to stream high definition content to WiDi-capable HDTVs or HDTVs equipped with a WiDi adapter.
