Are you thinking about a display device? Display devices, such as computer monitors, typically support a video connector. You’ll have to connect a monitor to a computer via a cable. The type of cable you’ll need to use, though, will depend on the device’s video connector.
Different display devices support different types of video connectors. You can check the back of a display device to identify its supported video connectors. The video connectors have ports. You can connect a cable to one of these ports, followed by connecting the other end of the cable to a computer. Below are four of the most common video connectors.
Digital Visual Interface (DVI) is a common video connector for display devices. It supports the transmission of high-resolution video data. There are DVI video connectors, for instance, that offer up to 720 x 1080 resolution, and there are DVI-D video connectors that offer up to 2560 x 1600 resolution.
You may encounter computer monitors and other display devices with a Video Graphics Array (VGA) connector. VGA connectors have been around since the 1980s. They use an analog method of data transmission. In the past, most computer monitors and display devices featured a VGA video connector. With that said, they’ve since been replaced by newer and more advanced video connectors like DVI.
There’s also the DisplayPort video connector. DisplayPort is a relatively new type of video connector. Like DVI, it supports the transmission of high-resolution video data. You can use a DisplayPort video connector for a high-resolution display device.
We can’t talk about common video connectors without mentioning High-Definition Multimedia Interface (HDMI). For new computer monitors and display devices, HDMI is arguably the most common. More newly manufactured computer monitors and display devices feature an HDMI video connector than all other types of video connectors. HDMI goes beyond video transmission by offering audio transmission as well. In other words, you can use a single HDMI cable rather than an audio cable and a video cable.
Not all display devices feature the same type of video connector. Some of them have a DVI or VGA video connector, whereas others have a DisplayPort or HDMI video connector. With that said, many display devices now feature multiple types of video connectors. If you’re going to buy a display device that doesn’t have a built-in computer — such as a computer monitor — you should check to see what type or types of video connectors it features.
