Type of connector is – Computer Analog Video.The features & specifications of the VGA connector include the following. Pin15 (ID3 / SCL): Monitor ID Bit-3 or I2C data clock.Pin12 (ID1 / SDA): Monitor ID Bit-1 / Data line with I2C bi-directional.Pin11 (ID0 / RES): Monitor ID Bit0 or Reserved.Pin9 (KEY): +5V DC output from graphic card.Pin4 (ID2 / RES) : Monitor ID Bit-2 or Reserved.Pin1 (RED): Red video (75 ohm, 0.7V peak-to-peak).These options also require less power so they conserve energy for both your device and monitor which will save you money on your electric bill compared to other options. Most other types of video display cords are designed to transfer digital information so they offer compatibility with newer devices that have better resolutions or more features than older equipment. VGA cables are the only option that can support analog signals which means they’re limited to a maximum resolution of 800×600 pixels, particularly if you want to maintain image quality throughout your transmission. One of the most significant considerations when choosing which cable to use is where each one falls in terms of the maximum resolution. However, if your computer only supports newer technologies like HDMI or DVI then you’ll find two very distinct differences between how they work compared to more traditional methods like the VGA cable. The VGA standard has been around for quite some time so if you’re working on an older device, it may still support video signals through this method. Do I need VGA if I have HDMI?Ī VGA cable is one of many different types of cables that can be used to connect devices together.Ĭonnecting a computer and monitor with this type of cord will allow the user to use every feature that both devices have to offer while enjoying optimal picture quality. There are several factors you’ll want to take into consideration when choosing between different types of cords including price, distance supported by the cable, durability of the material used to make them, additional support features offered by manufacturers like gold-plated connectors, or maximum resolution that they will work with among many others possibilities. Applications in which using this type of cord is important to include picture quality or when you have only one device to use for signal transmission at a time. The most important thing for you to know before making your selection is what your device supports since not all cables work with every type of hardware even if they fit in the ports.Įxamples of devices that can be used with VGA cables are older computers, projectors, HDTVs, plasma TVs, home theater receivers, and other analog video displays. When you’re looking at your computer monitor trying to figure out what kind of cord to use to connect it, you’ll have several options that will allow you to view your screen more effectively including a VGA cable or HDMI cable among others. It can be easy to confuse these different types of cords with one another because they all have different connectors on each end but they only differ in how the signal is transmitted. VGA is short for video graphics array while some other common cords are the S-video connector cord, A/V plug, and component cable.
VGA cables are just one example of a wider collection of similar cords that can be used to transmit digital video data between devices. These types of cables typically have three rings on them instead of five data pins like DVI or HDMI cables have while some models may opt for RCA plugs instead. In order for computers of that era to use this technology, they required special monitors that were designed specifically for the signal type.
It used another standard known as an RGBI cable with analog signals only. The video graphics array was introduced by IBM in 1987. Initially, it’s important to understand what a VGA cord is before you can learn how they work. If you want a high-quality connection between devices, then connecting them with a VGA cord may not be what you need but if all you want to do is connect a computer and a monitor then the VGA cable will suit your needs. The connectors on this cable are soldered together and cannot be separated, unlike their competing counterparts. These cables were the most popular methods for computers with CRT monitors to connect to their displays until HDMI and DVI emerged as the mainstream options. This type of cable, also called an RGB or RCA cable, has three female connectors that are designed to carry video signals.
