Video In Video Out, usually seen as the acronym VIVO (commonly pronounced vee-voh), is a graphics card port which enables some video cards to have bidirectional (input and output) video transfer through a Mini-DIN connector, usually of the 9-pin variety, and a specialized splitter cable.

VIVO is found predominantly on high end ATI video cards, although a few high end NVIDIA video cards have this port as well. VIVO on these graphics cards typically support composite, S-Video, and Component as outputs and composite and S-Video as inputs using six connectors total. Many other video cards only support component and/or S-Video outputs to compliment VGA or DVI, typically using a component breakout cable and an S-Video cable. It should be noted that while the component out signals support high definition resolutions, it does not support the HDCP standard which would be required for official HDTV support as set out by the EICTA. Also, a person using VIVO must have software that can display the input signal. For example, in the case of Nvidia GeForce series 6 and 7 video card users this means downloading Nvidia's WDM drivers.

Using a VIVO cable to use a TV as part of the desktop is disabled on Windows XP computers that use GeForce video cards with Scalable Link Interface (SLI) mode enabled, just as dual monitor mode is disabled the same way. The user will still briefly see some distorted imagery on a properly VIVO-connected television display at boot-up however. Therefore, VIVO option is regarded as a "useless" element, especially for gamers and users who do not wish to connect their computer to their TV.
