Hdmi input

Hdmi input types

As HDMI inputs are cable connections that transfer high-definition video and audio to entertainment centers, there are different kinds of those inputs. The kinds of inputs are determined by their physical structure and technical specifications.

HDMI input types include:

• Standard HDMI: This is the most commonly used input, and it is found on most TVs and computer monitors. The standard HDMI input can be used to connect gaming consoles, Blu-ray players, and streaming devices. Depending on the version, it supports resolutions of up to 4K.
• Mini HDMI: The mini HDMI input was designed for thinner and lighter portable devices like cameras, tablets, and laptops. Like the standard HDMI, it transfers both high-definition video and audio to and from devices. Its small size makes it more convenient to connect to devices that have less space and more portability.
• Micro HDMI: Even smaller than the mini HDMI input, the micro HDMI input can mostly be found on ultra-portable devices like smartphones and very small tablets. Adapters can be used to connect it to standard HDMI cables.

Some devices come solely with a micro HDMI output; therefore, an adapter is needed to connect it to a larger screen using the standard HDMI cable.

Different HDMI input types come with different capabilities. Knowing their specifications helps in connecting devices with a common understanding, especially when it comes to resolution and refresh rate. HDMI input types further include, but are not limited to, the following:

• HDMI ARC (Audio Return Channel): This special feature allows audio to be sent, or transmitted from the TV to a soundbar using a single HDMI cable. Using the HDMI ARC input eliminates the need for additional audio cables clogging the entertainment center. The HDMI ARC also allows users to control all devices using a single remote, hence improving user experience.
• HDMI eARC (Enhanced Audio Return Channel): Just like HDMI ARC, the eARC also transmits audio from the TV to a sound system using a single cable. It does, however, have enhanced features. The eARC supports higher-quality audio formats like Dolby Atmos and DTS. It also has simpler compatibility between devices. Because of the enhanced features, an eARC cable is required to connect to devices that have the eARC input.
• HDMI CEC (Consumer Electronics Control): This type of HDMI input integrates controls of all connected devices through the CEC technology. For example, devices like Blu-ray players, TVs, soundbars, and streaming devices can be controlled using a single remote. To activate the CEC input, it must be connected to a power source, and interoperability between devices is important.

Functions and features of HDMI input

HDMI, or high-definition multimedia interface, is a connector that can receive audio and video signals in high quality. The HDMI port can receive signals from various sources. An HDMI input from a device like a cable box, laptop, or gaming console can be used to direct the audio and video to a compatible display like a television, monitor, or projector. An HDMI cable provides a single connection for both high-definition audio and video without compression.

HDMI connectors have replaced older types of audio-video cables like VGA and DVI. They come in several sizes, including the standard, mini, and micro. The latest connector is the HDMI 2.1 version, which supports higher resolutions and frame rates, including 4K at 120 Hz and 8K at 60 Hz. It has features like:

• Enhanced Audio Return Channel (eARC): This feature allows devices like soundbars or AV receivers with an HDMI output to produce high-quality audio from a television without needing an additional cable.
• Variable Refresh Rate (VRR): Features found in gaming consoles and PCs that reduce or eliminate lag, stuttering, or tearing in gameplay.
• Quick Media Switching (QMS): This prevents the screen from blanking or flickering when switching between different media that has a different frame rate.
• Quick-Lock Capability: HDMI 2.1 connectors have the ability to lock better than previous versions to prevent users from pulling them out accidentally while data is still transmitting, which can cause it to corrupt.

Other features of the HDMI 2.1 version are the Quick Frame Transport (QFT) that reduces latency for smoother gaming, Game Mode, and Automatic Low Latency Mode (ALLM), which optimize gaming display performance. The Cable Power feature allows active HDMI cables to receive power from the HDMI output port, thus eliminating the need for an external power supply.
