High definition Multimedia interface, also known as HDMI, provides users with an interface to connect their HDMI-enabled devices to displays, like a TV or a projector.
The HDMI cable ensures that video and audio quality is intact and the signals are transmitted without any trouble.
There are 2 types of HDMI cables, categorized according to the bandwidth and data rate they carry with them. The first category HDMI cable has a pixel speed of 75 MHz and it supports a bandwidth of 2.23 Gbps. It can support up to 1080pi uncompressed signals.
The 2nd category HDMI cable has a pixel speed of 340 MHz and it carries a bandwidth of 10.2 Gbps. The resolutions it can support are 1440p and WQXGA.
While HDMI is a great technology, it has both pros and cons. Here is a detailed summary of both.
Benefits of HDMI
A single HDMI cable is used to carry both audio and video signals, removing the need to have two separate cables, which used to be the norm until HDMI got introduced in 2003. It makes connections less complex and time-consuming.
HDMI is greatly known for lossless transmission. The texts and symbols are displayed sharply on the screen and are not distorted thanks to no loss of signals.
Thanks to automatic configurations, HDMI allows people to have two-way communication which removes the need to manually select formats and resolutions. The best option is automatically selected. However, users still have the option to manually select their preferred format and resolution.
In addition to this, HDMI is also very secure as it prevents intruders from getting access to your data. Only connected and authorized devices can be used to access data.
Drawbacks of HDMI
The maximum lengths to which the HDMI cables can exceed to are limited. HDMI category-1 does not support transmission over 35 meters, whereas HDMI category-2 does not support transmission over 10 meters. This can be a problem for some user. However, the good thing is that you can use an extender to extend the length of the wire.
The authentication delay at both ends of the cable can cause a blank screen to occur, which during lectures or presentations can be a little problematic, and also ruin your viewing experience. It may also often be due to a poor quality cable. You should buy a good quality cable from a source like Koincable.
While HDMI cables are great, on the downside they can be quite expensive, especially when compared to analog cables. Still, they are quite a good option since they’re more durable than traditional wires and can be good for a long period of time.
Other than this, you will require a separate wire and HDMI-DVI adapter for the purpose of DVI interfacing.
HDMI cables, like any other product, has both pros and cons. However, when you look at it from a critical point of view, you will see how the pros overpower the cons in this one.
HDMI cables are the future for sure, especially with a new version expected to hit the market soon. It will definitely bring a lot more features to the table.
