摘要： A system comprises a first graphics controller adapted to couple to a first display, a second graphics controller adapted to couple to a second display, and a switch through which at least one of communications and power is provided to the second graphics controller. The system also comprises control logic coupled to the switch. The control logic causes the switch to preclude at least one of communications and power from being provided to the second graphics controller if the second display is not operatively coupled to the system.

摘要： In a method and system for assessing video quality, an analog video signal to be assessed is input. At least part of the incoming video signal is converted to digital values. The digital values are stored. A detector determines whether any stored digital value is outside an acceptable range.
