A video cable is a type of cable used to transmit video signals from one device (such as a computer, gaming console, or media player) to another device (like a monitor, TV, or projector). There are several types of video cables, each designed for different uses and delivering varying levels of signal quality. The most common video cables include:

1. HDMI (High-Definition Multimedia Interface):

Most common for modern displays and devices.

Carries both video and audio signals.

Supports high-definition and 4K resolutions, as well as higher refresh rates in recent versions (e.g., HDMI 2.0 or 2.1).

2. DisplayPort:

Primarily used for computer monitors.

Can support high resolutions, high refresh rates, and multiple monitors on a single cable (via DisplayPort daisy chaining).

Newer versions (DisplayPort 1.4 or 2.0) support 4K and 8K displays.

3. DVI (Digital Visual Interface):

An older standard, primarily used with computer monitors.

Available in several variations (DVI-I, DVI-D) for both digital and analog signals.

Does not carry audio.

4. VGA (Video Graphics Array):

An older, analog connection for video.

Common in older PCs and monitors.

Supports lower resolutions compared to digital connections like HDMI or DisplayPort.

5. USB-C / Thunderbolt:

USB-C ports with DisplayPort Alternate Mode or Thunderbolt 3/4 can transmit video signals.

Common in modern laptops and high-end devices.

Supports high resolutions and refresh rates (up to 4K or even 8K).

The type of video cable you use will depend on the devices you're connecting and the video quality you're aiming for. For example, HDMI is typically used for TVs and gaming consoles, while DisplayPort and HDMI are preferred for high-performance gaming monitors or PCs.
