Sony on Wednesday officially unveiled the powered-up PlayStation 4 Pro, which features smoother graphics, thanks to higher frame rates. This new version of Sony's bestselling video game console includes support for 4K resolution and high dynamic range, making it fully compatible with 4K/UHD displays. Some developers will add PS4 Pro support to existing games, as well as upcoming releases. Sony's own Uncharted 4 can be updated to take advantage of the 4K/HDR support immediately. Other titles -- including Call of Duty: Infinite Wars, Horizon: Zero Dawn, Mass Effect: Andromeda and Days Gone -- will provide support at their respective launches.
