ViewHD VGA | SVGA | UXGA 5FT Cable Support VESA DDC 1 | DDC2 (This is the MOST COMPATIBLE VGA Cable On the Market)
The majority of the VGA cables being sold on the market are not VESA DDC (Display Data Channel) Compliant. They do not support communication between the display unit and the VGA video source for Plug-n-Play. But most users treat VGA as play-n-play, even though VGA interface in general is not, don't even mention the case when using a VGA cable that doesn't even support plug-n-play / hot swap-able. This causes various video resolution, position and stability problems for monitors / HDTVs and VGA related video converters / adapters.This VGA cable is specifically introduced to address these problems. It supports VESA DDC1, to allow the monitor to tell its parameters to the VGA video source / computer for optimum performance setting; it also supports VESA DDC2 to enable bidirectional communication: monitor can tell its parameters and the computer can adjust monitor settings.New HDTVs with VGA port and many VGA video converters / adapters require the VESA DDC Compliant cable to obtain the best video performance provided by the display unit.How to check: Many basic / low cost VGA cables don't contain the wires in the cable to connect the three monitor ID pins: 11, 12, and 15 (even though all VGA connectors appear to have 15 pins).  Anyone with a digital multimeter can check the connectivity of these pins to verify. Also, if the computer says the external VGA display is "Generic Non-PNP Monitor", it means the VGA cable is not VESA DDC compliant.  In many cases, user can not specify the best video format for the display to get the best performance. In the worst case, user may not be able to get video at all using the basic VGA cable.
