You get will be very knowledgeable about VGA cables interesting fact after reading the post, VGA cables were primarily used for IBM computers, however many computer manufacturers realized the advantages of these cables and began using this technology as standard in all computer models. The main function of VGA cables is to transfer data from one device to another and provide high-resolution images.
Interesting facts about VGA cable that you do not know, VGA (Video Graphics Array) is a common standard for video output that uses analog signals. VGA was first introduced in 1987 by IBM for 640×480 displays. VGA connectors have many pins, each of which has its own function on the screen display. Although most modern electronic devices have started using digital signals for video transmission, VGA cables still work their way into some relatively old laptops, televisions, and monitors.
Interesting Facts About VGA Cable
Facts Numbers 1.
The standard VGA monitor interface has a 15-pin D-subminiature connector in the “E” shell, variously called “HD-15”, “DE-15” and “DB-15”.
Facts Numbers 2.
BNC breakout cables typically use five connectors, one each for red, blue, green, horizontal sync, and vertical sync, and do not add the other signal lines of the VGA interface. With BNC, coaxial cables are fully interconnected so that no crosstalk or external interference is possible.
Facts Numbers 3.
VGA uses low-voltage analog signals, signal loss becomes a factor with low-quality or excessively long cables. Solutions include shielded cables, cables that include a separate internal coaxial cable for each color signal, and “broke-out” cables that use a separate coaxial cable with BNC connectors for each color signal.
Facts Numbers 4.
A VGA cable is primarily used to connect computers and laptops to screens and monitors, although you may also find this connection on older AV equipment.
Facts Numbers 5.
The VGA port is now a relatively old connection type, it still has its uses, so don’t be surprised if you find yourself using one from time to time. There are still times when you might need to use a VGA connection.
Facts Numbers 6.
You might be surprised to know that you can connect VGA to HDMI, which can be extremely useful if you want to connect older devices together. But that’s not all. You can even connect HDMI to VGA!
Facts Numbers 7.
Did you know, that there are two types of VGA cables: 14-pin and 15-pin? 14-pin cables will work in applications, but 15-pin cables may be required for wider display compatibility. This product is a 15-pin VGA cable. Pin 9 was removed from 14-pin cables because the key signal became obsolete with modern computer monitors and was no longer used in default applications of the VGA standard.
Facts Numbers 8.
Every cable configuration and application is unique, making it difficult to provide an accurate length estimate. For example, VGA cables can still operate up to 150 feet if properly shielded.
Facts Numbers 9.
Shielding protects the VGA cable signal from electrical interference created by other devices. To combat the effects of electrical interference, organizations or professionals in mission-critical applications use boosters and equalizers to send VGA signals at longer distances.
