what is a DVI cable?

A DVI (Digital Visual Interface) cable is a type of video cable used to connect a computer to a monitor or other display device. It was commonly used before HDMI became standard but is still found in older monitors and graphics cards.

Types of DVI Connections:

There are three main types of DVI connectors:

1. DVI-D (Digital Only) – Transmits only digital signals and is commonly used for LCD monitors.

2. DVI-A (Analog Only) – Transmits only analog signals and is mostly for older CRT monitors.

3. DVI-I (Integrated) – Supports both digital and analog signals, making it more versatile.

Additionally, DVI cables come in single-link and dual-link versions:

1. Single-link: Supports up to 1920x1200 resolution at 60Hz.

2. Dual-link: Supports up to 2560x1600 resolution at 60Hz, offering more bandwidth.

DVI vs. HDMI & DisplayPort:

1. DVI vs. HDMI: HDMI carries both video and audio, while DVI only carries video.

2. DVI vs. DisplayPort: DisplayPort has higher bandwidth and supports modern high refresh rates.

While DVI is still found on some older monitors, newer setups typically use HDMI, DisplayPort, or USB-C for better performance and compatibility.
