Video-in Video-out (VIVO) - Limitations

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 Nvidia GeForce series 6 and 7 video card users this means downloading Nvidia's WDM drivers.

Additionally, On Windows XP computers that use GeForce video cards with 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.

Famous quotes containing the word limitations:

    Much of what contrives to create critical moments in parenting stems from a fundamental misunderstanding as to what the child is capable of at any given age. If a parent misjudges a child’s limitations as well as his own abilities, the potential exists for unreasonable expectations, frustration, disappointment and an unrealistic belief that what the child really needs is to be punished.
    Lawrence Balter (20th century)

    No man could bring himself to reveal his true character, and, above all, his true limitations as a citizen and a Christian, his true meannesses, his true imbecilities, to his friends, or even to his wife. Honest autobiography is therefore a contradiction in terms: the moment a man considers himself, even in petto, he tries to gild and fresco himself.
    —H.L. (Henry Lewis)

    ... art transcends its limitations only by staying within them.
    Flannery O’Connor (1925–1964)
