Types Of HDMI Ports

You first need to know that a TV’s HDMI is compatible with any HDMI device. Moreover, you can use HDMI ports for any purpose. The following are some of the HDMI ports you should know.


In some devices, the HDMI STB will get referred to as HDMI1. In other devices, it is called by its original name. It would be best to connect game consoles such as Xbox and PlayStation to an HDMI STB port. However, you can have the same result if you choose to use another HDMI port.


HDMI DVI ports on the back of the TV have a label of HDMI 2. Connecting a TV, computer, or another display to a device is easier with this adapter. However, DVI ports cannot send sound.

DVI connections come in two types which are DVI-I and DVI-D. In addition, Both of them have pins arranged in rows and columns within tiny square holes. The DVI-D type has a narrow dash line. In contrast, the DVI-I port has two holes above and below.

DVI-I supports an analog signal, while DVI-D supports a digital signal. Dual-link ports, a new form of DVI interface, are now available on the market.


HDMI ARC port is the port with HDMI 3 in the reverse audio channel. HDMI ARC port focuses on audio. With the Arc cable, stereos receive sound that isn’t compressed. Older HDMI connectors provide 5.1 sound, but only in compressed form.

The HDMI DVI Ports (Digital Visual Interface)

Every graphics card still has a DVI port. However, the connection is dwindling in popularity. The video signal is the same as HDMI but only without the audio. If you use a DVI-to-HDMI connection, modern graphics cards can transfer audio.

Dual-link DVI supports 2560×1600 resolution, whereas single-link DVI supports 1,920×1,200. If you have a 1080p 144hz screen, DVI is a fantastic option because it supports 144hz refresh rates.

However, DisplayPort or HDMI are the options to go with if you want a 4K TV display. With a passive adapter, DVI can get adapted to VGA like the other cables.

The DVI-D Connector

The DVD-D is the digital format connector. The role of DVD-D is to connect digital LCD monitors to DVI graphics cards. You can find the Single-link and dual-link versions of DVI-D. The dual-link version is twice as powerful and fast as the single link type. Thus it would be best to use dual-link for larger displays.

The DVI-A Connector

The analog version of DVI is the DVI-A. DVI-A connectors carry signals from DVI graphics cards to an analog display, like a CRT monitor. A digital to analog converter gets used here. However, the results are still better than if you were using a VGA cable.

The DVI-I Connector

DVI-I is the integrated format if you want to accommodate both digital and analog devices. DVI-I cannot convert a pure DVI-D output to something used by DVI-A devices. However, you can use it as either a DVI-D or DVI-A Cable, depending on your preferences.

Using a single cable for both digital and analog screens saves time and money. Moreover, single-link and dual-link versions of DVI-I are also available. You will find 29 pins in the DVI-I dual-link.
