What is a DVI cable for?

A DVI cable (Digital Visual Interface) is used to connect a video source, like a computer, to a display device, such as a monitor or projector. It's designed to carry video signals, not audio (unlike HDMI), and was commonly used before HDMI and DisplayPort became standard.

Here's what DVI is typically used for:

1. Connecting desktop PCs to monitors

2. Supporting higher resolutions than VGA (analog)

3. Digital signal transmission (depending on the DVI type)

4. Some versions support analog signals too (useful for older displays)

Types of DVI:

1. DVI-D (Digital only) – for digital displays (most modern monitors)

2. DVI-A (Analog only) – for analog displays (like old CRTs)

3. DVI-I (Integrated) – supports both analog and digital (versatile)

While it's less common now, DVI can still be useful if you're using older hardware or monitors that don't support HDMI or DisplayPort.
