An auxiliary screen support system for a computing device has mounting members arranged to be disposed on opposing lateral sides of a primary screen of the computing device in use. A retaining member extends between the mounting members, and is configured to hold the mounting members relative to the opposing lateral sides of the primary screen. At least one mounting member is configured to bear an auxiliary screen such that the auxiliary screen is hung relative to the primary screen in use. One or both mounting members may be formed as a unitary, rigid body and may be configured to hold an auxiliary screen at a fixed obtuse angle relative to a primary screen of the computing device.
