C2G 81529 HD15 VGA Female to VGA Female Gender Changer / VGA Adapter

Product Information

A VGA to HDMI converter is what you need to convert the VGA signal from your computer to the HDMI port on a monitor or TV.

They are often used in schools, businesses, and homes when multiple monitors are being run off one VGA port, or if the cable between the monitor and the computer will be excessively long (often pictures appear blurry or have minor artifacts if the cable runs too far without an extender). Many modern graphics adapters can modify their signal in software, including refresh rate, sync length, polarity and number of blank lines. DVI to VGA converters work because the signal is going from digital to analog, which is just a matter of translation in the DVI pins since DVI carries both analog and digital signals. Female connections are the reverse, having inward holes that allow the male cable to fit perfectly with the female connection.In both its modern and original variants, VGA utilizes multiple scan rates, so attached devices such as monitors are multisync by necessity. The only other distinction that needs to be made is identifying the type of connection at both ends; whether they're VGA, DVI, or HDMI, but that shouldn't be difficult given they look very different from one another.

What Is VGA? (Definition of Video Graphics Array) - Lifewire

The VGA connector is a three-row, 15-pin D-subminiature connector referred to variously as DE-15, [2] HD-15 [4] or erroneously DB-15(HD).The terminology here is sometimes used rather interchangeably when it comes to labelling various types of VGA cable and can be a little vague. Within a 15-pin connector, the red, green, and blue signals (pins 1, 2, 3) cannot be shielded from each other, so crosstalk is possible within the 15-pin interconnect. With VGA, DVI, and HDMI video cards and monitors all mixed in together in the real world, you're bound to want a VGA converter if all you have is a VGA monitor or video card.

providing a higher quality connection with less crosstalk [10] by utilising five separate 75 ohm coaxial cables. BNC prevents crosstalk by maintaining full coaxial shielding through the circular connectors, but the connectors are very large and bulky.With the implementation of the VESA DDC specification, several of the monitor ID pins were reassigned for use by DDC signaling, and the key pin was replaced with a +5V DC output per the DDC spec. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, [1] as well as many monitors, projectors and high-definition television sets.
