'''Video in video out''' (usually seen as the acronym '''VIVO'''), commonly pronounced ({{IPAc-en|ˈ|v|i|.|v|oʊ}} VEE-voh), is a [[Engineering:Computer port (hardware)|graphics port]] which enables some [[Engineering:Video card|video card]]s to have [[Engineering:Duplex (telecommunications)|bidirectional]] (input and output) analog video transfer through a [[Engineering:Mini-DIN connector|mini-DIN connector]], usually of the 9-pin variety, and a specialised splitter cable (which can sometimes also transfer analog audio).

VIVO was found on high-end [[Company:ATI Technologies|ATI]] and NVIDIA computer [[Engineering:Video card|video card]]s, sometimes labeled "<small>TV OUT</small>".  VIVO on these graphics cards typically supports [[Composite video|composite]], [[Engineering:Component video|component]], and [[S-Video]] as outputs, and composite and S-Video as inputs.  Many other video cards only support component and/or S-Video outputs to complement [[Video Graphics Array|VGA]] or [[Digital Visual Interface|DVI]], typically using a component breakout cable and an S-Video cable.  While component-out operation supports [[Engineering:HDTV|high-definition]] resolutions, it does not support the [[Engineering:High-bandwidth Digital Content Protection|HDCP]] standard which would be required for official HDTV support as set out by the EICTA.

Some practical uses of VIVO include being able to display multimedia stored on a computer on a TV, and being able to connect a [[Engineering:DVD player|DVD player]] or [[Engineering:Video game console|video game console]] to a computer while continuing to allow viewing via a TV monitor. VIVO itself, however, can not decode broadcast signals from any source, and so, like HDTV sets without [[Engineering:ATSC tuner|tuners]] and [[Engineering:Composite monitor|composite monitor]]s, additional equipment is required to be able to show broadcast TV programs.

Some manufacturers enable their version of the VIVO port to also transfer sound.

== Limitations ==
The VIVO output on graphics cards is often not used by those who have no need to connect their computer to a TV. Also, there can be issues in software supporting the use of VIVO ports.

A computer using VIVO must have software that can handle an input signal. For example, in the case of [[Company:Nvidia|Nvidia]] [[Engineering:GeForce|GeForce]] series 6 and 7 video card users this means [http://www.nvidia.com/object/wdm_drivers.html downloading Nvidia's WDM drivers]. 

Additionally, On [[Software:Windows XP|Windows XP]] computers that use [[Engineering:GeForce|GeForce]] video cards with [[Engineering:Scalable Link Interface|Scalable Link Interface]] (SLI) mode enabled, using a TV to display part of the desktop via VIVO is disabled, just as dual-monitor mode is disabled. Confusingly, however, some distorted images may be visible on a properly-connected VIVO-driven television display at boot-up due to the fact that prior to the OS loading the display driver, the video bios might initialize outputs that are then unavailable once the OS takes over and the driver loads into SLI mode.
