What You'll Learn
HDMI cables transmit audio and video
HDMI, or High-Definition Multimedia Interface, is a cable that transmits both audio and video signals through a single cable. This makes it a highly efficient connection option for modern entertainment systems, as it simplifies the setup of home theatres by reducing the number of cables needed.
HDMI cables have the capacity to handle just about any home theatre audio system and support high-resolution audio formats like Dolby TrueHD, DTS-HD Master Audio, and even more advanced formats like Dolby Atmos. This allows for uncompressed, studio-quality sound, which is a significant improvement over older formats.
HDMI cables come in three types: standard connector (Type A), mini HDMI cable (Type C), and micro HDMI (Type D). The standard connector is used for larger devices like high-definition TVs, while the mini and micro HDMI cables are used for smaller devices like smartphones, tablets, cameras, and camcorders.
The quality of the internal components and construction inside the HDMI cable will make a difference in your high-definition experience, especially when it comes to lifelike sound and audio-video. For example, a low-end HDMI cable may not allow you to fully enjoy all the realistic detail, colour, and sound of today's high-definition experience.
HDMI cables have gone through multiple revisions since their introduction in 2003, with each version adding new features while maintaining backward compatibility. Newer versions include advanced capabilities such as 3D video, higher resolutions, expanded colour spaces, and the Audio Return Channel (ARC), which allows audio to be sent from a display back to an audio system over the same HDMI cable.

DVI cables transmit video only
DVI, or Digital Visual Interface, is a connection type used to transmit digital video signals between computers and other display devices, such as monitors and TVs. It is a video display interface developed by the Digital Display Working Group (DDWG) to create an industry standard for the transfer of uncompressed digital video content.
DVI cables are designed to transmit video signals only, meaning audio cannot be transferred using a DVI connection alone. This means that if you're connecting your PC and monitor with a DVI cable, you'll need an additional audio cable to send sound from the computer's sound card to the monitor's built-in speakers.
However, there are special bidirectional cables available that feature both a DVI plug on one end and an HDMI port at the other end, allowing for both audio and visual data transfer. These cables enable you to use various devices with either type of input. Additionally, if your monitor or TV has an integrated Audio Return Channel (ARC) port, it can connect directly to your PC or laptop's sound card via HDMI, eliminating the need for a separate audio cable.
While DVI cables do not inherently support audio, certain graphics cards have been known to support audio on the DVI port using HDMI signalling with the correct adapter. This setup involves adjusting the DVI function option to [as HDMI] in BIOS\Advanced\North Bridge Configuration and setting HDMI as the default playback device in the Control Panel\Sound settings.
In summary, while DVI cables are primarily designed for transmitting video signals, there are workarounds and adaptations that enable audio transfer in conjunction with these cables.

HDMI and DVI cables can be used interchangeably with adapters
HDMI and DVI cables have different functions and capabilities, but they can be used interchangeably with adapters.
HDMI cables are capable of transferring both audio and video signals through a single cable, due to their advanced sound codecs. This makes them a convenient option for users who want to minimise the number of cables they use. However, because of the number of connections involved in transferring data, HDMI cables may not offer the same picture quality as DVI cables.
DVI cables, on the other hand, are video-only and cannot transmit audio. They are capable of reaching higher resolutions than HDMI cables and offer better refresh rates, with single-link cables offering resolutions up to 1920 x 1080 at 60Hz, and dual-link cables reaching 2560 x 1440 at 60Hz.
Despite their differences, HDMI and DVI cables can be used interchangeably with the use of adapters. For example, if a cable box or PC has a DVI output, but a TV or monitor only has HDMI input, a DVI-to-HDMI adapter can be used to connect the video, with audio cabled separately. This works because the HDMI circuit detects the DVI signals and switches to the DVI protocol.
It is important to note that the type of DVI connection matters when using adapters. DVI-D is digital-only and does not have the analog pins required for simple adapters to work. In addition, some DVI displays may lack support for HDCP, making them unable to display protected content, even if they are otherwise compatible with HDMI sources.
In summary, while HDMI and DVI cables have distinct functions and capabilities, they can be used interchangeably with the help of adapters. However, users should be aware of the limitations of each cable type and the specific requirements of their devices to ensure compatibility.

HDMI cables have three connector styles
HDMI cables are the primary way to connect smart devices to a TV or home theatre setup. They are used to connect computer monitors, laptops, HD TVs, and game consoles. HDMI cables can transmit both video and audio signals.
The mini HDMI cable, also known as Type C, is used for smaller devices like smartphones, DSLR cameras, tablets, and even some laptops. It shares the full functionality of standard HDMI connectors but is smaller in size.
The micro HDMI connector, or Type D, is a 19-pin connector that is often used for tablets and smartphones. It is even smaller than the mini HDMI connector but provides the full functionality of its larger counterparts.
The main difference between the three connector styles is the size and the devices they are typically used for. All three connectors have the same number of pins and support the same resolutions and features.
When choosing an HDMI cable, it is important to consider the devices you will be connecting and select the appropriate connector style and cable length. It is also worth noting that while HDMI cables can vary in price, the quality is not always reflected in the price. There are good quality HDMI cables available at affordable prices.
