Even though wireless HDMI is not a new gadget, it is not very popular yet. It is an advanced version of the standard cable based HDMI. Wireless HDMI is nothing but a system of transferring video and audio from a source device to a television. The source device can be anything such as a Blue Ray Player, a Computer PC or a Gaming console and through a wireless HDMI, the video and audio output of the device can be transferred to a TV without any wire. The wireless HDMI devices come with a transmitter which transmits the audio and video from the source device and a receiver that receives the signal and makes an output through the TV.
The benefits of a wireless HDMI:
You can get rid of all the cables required for a standard HDMI
You can get rid of all the cables required for a standard HDMI
It supports multiple HDTVs and allows independent viewing in each TV
With a wireless transmitter, the output can be sent to multiple TVs through the individual wireless receivers.
While the source device is in a different location wireless HDMI allows viewing elsewhere without laying meters of cable in the house
Extremely effective for office use where a presentation can be played from a laptop outside the conference room or when a presentation needs to be run on multiple TVs from a source PC.
Easy for putting a digital signage outdoors
You don’t have to worry about the number of HDMI ports at the back of your TV
Factors to consider while purchasing Wireless HDMI:
Basically, four major things need to be considered while purchasing a wireless HDMI,
Signal strength: The wireless HDMI has to be strong enough to pass through walls, curtains and household equipment including electronic devices. Unless the wireless signal strength is good enough it is not useful.
Latency: Latency is nothing but the time taken for the signal to reach the output device from the source device. The best wireless HDMI devices give latency of 1 millisecond. If the latency is high it will take more time to reach the TV.
Accommodate 1080P: it must be checked whether the wireless HDMI accommodates 1080p. Unless it supports 1080p it is not worth buying.
Operation: You must check if your device operates with a dynamic frequency selection feature. This will reduce congestions in into the device by searching low interference frequency channels.
What are the features the best Wireless HDMI should have?
The Best Wireless HDMI should come with the following features:
Signal range of not less than 30 metres
Signal strength of at least 60 G Hz
Compatibility with all types of video formats
Uncompressed audio and video transmission
Multiple output device connectivity
A latency of less than 1 millisecond.
Features to consider before you buy:
There are certain features you need to consider before making a buying decision.
You have to check if the device has strong wireless connectivity which passes through walls and other devices. 60 G Hz signal strength should be ideal
Check if it allows multiple outputs: this depends on your home or office setup. The more output it gives the better. Even if you do not have an extra TV today, the provision should be there for future.
Check if the transmitter can be placed in a separate room. Some wireless HDMI transmitters are required to be kept in the same room as the source device. If the feature of keeping the transmitter in a separate room is there, it gives you more flexibility while using
Check if the video transmission is uncompressed. Unless the video transmission is uncompressed you are getting a low-quality output. Always select the model that transmits video and audio uncompressed
Check if it supports surround sound and HD Audio. Do not only concentrate on the video side. A good audio output is also important and you should always check if the device transmits surround sound.
Check whether the device gives a 3d video output. Even though very few devices come with this feature this is an excellent option, especially for home theatre.
Video compatibility is essential. Always go for the model that supports most number of video formats. You never know which video format you need to watch so keeping the provision is not a bad idea. Even though most devices come with compatibility with almost all video formats, verification before buying is important.
Most importantly, consider the price. Make a good comparison between the prices and features. You might end up buying a very expensive model with features that you cannot use in your devices. Decide which will be your primary devices and what type of use are you going to do and accordingly make a choice.
