Kramer Electronics released a new addition to its Tools line of compact products, the VA-1VGAN a computer graphics EDID emulator. The VA-1VGAN is housed in the Kramer Pico Tool enclosure and carries a list price that is $90 less than the older model, according to the company.
The VA-1VGAN captures and emulates the Extended Display Identification Data (EDID) of a display, a data structure consisting of 128 pieces of information that a display provides to the graphics card of a connected computer source. The EDID describes the display's capabilities so the can source can output the best possible signal for that display. The source and display exchange this information over the Display Data Channel 2 (DDC2) using pins 12 and 15 of a standard 15-pin HD computer graphics video signal connector.
Kramer's new emulator is designed in such a way that if a display is turned off, temporarily disconnected, or is out of communication with the source, the source continues to output the best possible signal resolution, says the company. The VA-1VGAN makes the source think that the display is still directly connected, even when the EDID information is unavailable.
Systems such as matrix switchers, distribution amplifiers, five-wire coax signal distribution, and twisted-pair range extenders are typically unable to pass EDID information, because pins 12 and 15 from the source are not available. In these instances, say Kramer officials, the VA-1VGAN captures EDID information from the display when it is inserted into the system just after the source and it sends the EDID information to the source, allowing the best possible signal resolution to be output at all times. Even if the DDC2 channel does not connect the source and the display, the source will still effectively recognize the display, officials say.
The Kramer VA-1VGAN is currently available with a U.S. list price of $105.
