VGA Cable 1.5 meter extra wire just means more voltage drop. And if you’re using a peripheral connector to PCI Express adapter then be sure to plug each of the adapter’s peripheral connectors into a separate PSU cable. They gave you two peripheral connectors for a reason.
VGA Cable 1.5 meter connectors are used to transmit video from a source (like a computer) to a display device (like a monitor, TV or projector). The main difference between VGA and DVI is in picture quality and the way the video signals travel.
VGA connectors and cables carry analog signals while DVI can carry both analog and digital. DVI is newer and offers better, sharper display compared to VGA. You can easily tell them apart because VGA connectors (and ports) are blue while DVI connectors are white.
In contrast to HDMI, neither VGA nor DVI support audio. So when connecting with a TV or a projector or home theater system, you can use a single HDMI cable to carry both audio and video signals or use a single VGA/DVI cable for video and a separate audio cable.
A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector was provided on many video cards, computer monitors, laptop computers, projectors, and high definition televisionsets. On laptop computers or other small devices, a mini-VGA port was sometimes used in place of the full-sized VGA connector.
The VGA interface is not engineered to be hotpluggable (so that the user cannot connect or disconnect the output device while the host is running), although in practice this can be done and usually does not cause damage to the hardware or other problems. However, nothing in the design ensures that the ground pins form the first make or the last break in the connection, so hotplugging may introduce surges in signal lines that may or may not be adequately protected against damage. Also, depending on the hardware and software, monitor detection is sometimes unreliable when hotplugging a VGA connection.
