It is important to identify the type of video connector that is available on the computer and the monitor or projector. Using the correct type of video cable helps prevent video or display problems.
There are two types of video transmission methods: digital and analog (see table below). each video connector is capable of transmitting analog or digital video signals. analog video connectors such as s-video, composite, vga, svga, and dvi (analog) do not support playback of protected high definition digital content, such as blu-ray movies, over an analog connection, you will probably get an error message or the movie will play in lower quality resolutions.
