There are two screws attached to the cable for a secure connection.Īnd VGA is very rarely used now the 13h mode was used in computer gaming in the late 80s and early 90s. A VGA socket is usually colored blue and has 15 pins in total with 3 rows having 5 pins in each. RGBHA video signals (R stands for Red, G for Green, and similarly the rest stands for Blue, Horizontal Sync, Vertical Sync) can be carried by VGA cables. You may use whichever version you prefer. There is another mode called 13h, which uses 256 colors at a lower resolution of 320 x 200 pixels. It supports image resolutions at a maximum of 640 x 480 pixels in 16 colors. Essentially, VGA is a 15-pin connection made to transmit images it only works with analog signals.Ĭompared to other analog connectors, VGI can give you a higher quality image. It was developed in 1987 by International Business Machines (IBM). VGA is one of the oldest connectors among the ones discussed in this article.
Previously made to connect display devices to video sources, DisplayPort can transmit both audio and digital images now.
It was designed in 2006 by the Video Electronics Standards Association (VESA). One difference is DisplayPort is license-free, unlike HDMI. This cable and connection type is very comparable to our previous topic of discussion, HDMI. However, because DVI devices do not support audio, DVI-to-HDMI conversions can not carry the 8-channel audio data. The conversion type is pin-to-pin, so ideally, there should not be any detectable signal loss. This type of cable features Consumer Electronics Control (CEC) connection, which enables the user to operate several devices with a single remote control it also permits HDMI devices, if necessary, to control each other.Īnd HDMI cables have backward compatibility with older HDMI versions and DVI devices for videos.
The newer version, HDMI 2.1, was announced earlier this year, which can support 48 GB per second. HDMI 1.4 can support up to 4096 x 2160 high-resolution videos and 192 kiloHertz 24-bit uncompressed audio you can also use it for transmitting 3D videos. Uncompressed digital video & audio is transmitted by HDMI cables with only one single cable.Ī group of electronics manufacturers including Toshiba, Sony, and Sanyo has created HDMI for transferring uncompressed video and either eight-channel compressed or uncompressed audio into digital TVs, computers, Blu-ray or DVD players, and more. High Definition Media Input (HDMI), although proprietary, is a wildly successful digital video and audio transfer interface. In the next section, I will talk about the most relevant ones of these cable types and their uses in thorough detail. USB connector and 12V trigger work with both analog and digital connections, and therefore, does not fall under the two categories. Analog cables include VGA, Component Video, S-Video, Composite Audio & Video, 3.5mm input, 3.5mm output, etcetera. HDMI, DisplayPort, Ethernet, DVI, Optical are digital cables. There are two broad ranges you can divide into the types of connections or cables a projector supports, which are – digital cables and analog cables.
