HDMI cables
When looking to buy an HDMI cable for a UHDTV, HDTV, HD projector, or home theater receiver, there are several factors to consider.
And even though it seems like just one of many connections or cables necessary to enjoy better picture quality, HDMI cables are more than only a cable that goes on the HDMI port on a television.
HDMI cables come with a pre-established set of standards that allow high-definition electronics to transmit communication protocols and a definitive need for a home theater installation, television installation, projector installation, or an audio and video receiver setup.
There are several types of HDMI cables also; some of them provide a higher bandwidth than others, some of them come in the form of a standard cable with ethernet, a high-speed cable, a high-speed cable with ethernet, and of course, a simple standard cable.
Benefits of HDMI cables
HDMI cables provide significant benefits.
Starting with a higher conversation rate, better transmission protocols, more frames per sec, and a more robust bandwidth - HDMI cables are the best.
Signal conversion
HDMI cables are compact audio-video cables used to transmit uncompressed video, data, and uncompressed or compressed digital audio data from an HDMI device to a compatible high-definition television, high-definition projector, computer monitor, or an audio-video receiver with a digital audio device.
New high-definition televisions display a more significant amount of colors than their older versions.
These create the need for faster data transmission then than regular digital televisions.
When a television receives information digitally, it does not have to spend processing power or time transforming the signal from analog to digital to high definition.
<h2>HDMI Protocols</h2>
The HDMI standard is a set of protocols used to transmit high-bandwidth data between digital devices. It was created by a group of manufacturers dedicated to the production of electronics.
Using devices that are HDMI capable, HDMI technology provides a significant difference in a home theater system.
The current standard can carry 8K60 and 4K120, Dynamic HDR, and increased bandwidth with a new 48G cable, and it supports eight channels of uncompressed audio, enough for a 9.2 surround sound system.
Best of all, an HDMI cable reduces the number of wires required to connect audio and video components, and it can lower the number of remote controls needed to operate a system.
2.1 HDMI cables
2.1 is the latest HDMI technology! With televisions only being manufactured inexorably toward Ultra HD "4K" and "8K," it was clear that the need for more bandwidth in the connection to handle the future's higher resolutions and frame rates.
HDMI 2.1 delivers, supporting 4K 2160p x up to 120 frames per second and 8K to 60 frames per second. Â It allows for full-resolution 8K along with a higher frame rate of 4K content.
It is all about the bandwidth!
HDMI cables deliver many new specifications to take your audio and video entertainment to an entirely new next level.
Even the main differences between 8k and 4k UHDTV are undeniable.

HDMI cable with Ethernet
This HDMI cable type provides precisely the same performance as a standard HDMI cable. Additionally, a dedicated data channel, commonly known as the HDMI Ethernet Channel, is mostly used to synchronize a device to a network. Simply put this type of cable has the functionality of an HDMI cable and an ethernet cable built in.
HDMI Ethernet Channel functionality is only possible if the linked devices are HDMI Ethernet Channel capable.
High-speed HDMI cable
A high-speed HDMI cable handles video resolutions of at least 1080p, including more advanced display technologies like 8K, 4K, 3D, and Dynamic HDR.
HDMI cable advancements
HDMI cables provide an efficient way to understand how all the technologies vary and how all the improvements reflect on the screen.
All these significant advancements have provided outstanding differences depending on the types of HDMI cables, bandwidth, and high speed and standard HDMI cables with ethernet channels.
