HDMI cables are available in different versions and are compatible with specific devices. This means that a cable rated with an HDMI 1.2a specification should work effectively on devices with HDMI 1.0, 1.1 and 1.2. However, it may not work properly with HDMI 1.3 devices.
The HDMI cables are divided into two different categories:
• Specifically designed for high-definition frame rates and HD resolutions of up to 720p
• These cables are specially designed for resolutions of up to 1080p
While the HDMI specification has specific requirements for the maximum cable length, HDMI cables are mostly available in lengths ranging from 3′ – 50′. Buying a longer length HDMI cable will not only cost more, but also create signal loss problems due to attenuation. Due to this reason, it is always recommended to buy an HDMI cable of the appropriate length.
With plenty of cheap HDMI cables available out there you must make a conscious effort to buy a high quality one. The quality HDMI cables are specially designed with higher tolerances for better performance. Moreover, premium HDMI cables also have a longer service life. Ideally, look for HDMI cables that feature gold plated connectors. This way you can ensure you get the best possible signal quality.
A chain of different HDMI cables can also be connected to equalisers, repeaters and amplifiers. Moreover, HDMI cables can also transmit audio and video signals without using different connectivity cables. Lastly, the cost of HDMI cables is another important thing you need to consider.
So, if you are planning to buy an HDMI cable, remember to do your research on the above mentioned points and make your selection accordingly.
