Sometimes it isn’t convenient to run an HDMI cable between your HDMI source and your TV/projector, especially when they are located in separate rooms. To solve this problem, you can use a wired HDMI extender kit to extend the video source by running a CATx cable over a long distance. However, it often requires drilling holes, running cables all over the wall and even professional guidance from an installer. In comparison, it saves more time and efforts by adopting a wireless HDMI extender that most families nowadays tend to utilize for their home theater system installation. In this blog, we are going to learn about the top considerations for choosing a right wireless HDMI extender.
Transmission Distance/Range
The first key factor you need to think about is the transmission range, which has maximum influence on the price of the device. A wireless HDMI extender is usually composed of a transmitter and a receiver. The range is the distance up to which the transmission is possible, and it can be anywhere from 30 feet to 600 feet. You should choose a unit with a range based on the way you place the device as well as the size of your house. There is no need to invest in a very long-range extender when you need a short-range, as a higher range usually means a higher price. A premium and long-range extender like AV Access HDW100 can transmit 1080P HDMI signal wirelessly up to 200m/656ft in an open field. Even if there is an interior drywall or other obstructions between the transmitter and the receiver, the signal can still transmit 10m-50m(32ft-165ft), stable and reliable.
Audio and Video Quality
Another important factor is the audio and video quality, on which continuous improvements have been made by manufacturers to provide the best picture and audio quality possible. Some wireless extenders can transmit up to 4K ultra HD image, while some can only transmit 1080P full HD or lower than that. Anyway, please remember the picture quality also depends on your TV set. A 1080P TV set cannot provide 4K quality just because the HDMI extender supports it. Investing in higher picture quality will be a waste of money if your TV does not support it.
Installation Difficulty
One of the biggest advantages of a wireless HDMI extender lies in its ease of use. Most of the wireless HDMI extenders on the market are built with compact and portable design, so you can place and install the unit almost anywhere in your house. What’s more, you don’t have to install a special driver or software to pair the transmitter with the receiver. AV Access HDW100 wireless extender is highly recommended here. The transmitter and the receiver are quite portable and easy to install. After power-on, they can automatically get paired within the appropriate range. No software driver or complicated setting is required; just plug and play.
Transmission Latency
The transmission latency of a wireless HDMI extender usually ranges from 100ms to 500ms, less than a second, ideal for home theater, video projection, video presentation, etc. However, it is not great for using a PC or playing video games, as literally any person can notice this degree of latency when moving the mouse or playing on game console.
High-performance wireless HDMI extenders like AV Access HDW200 can transmit lossless signal and boast relatively low latency (about 100ms to 200ms), which depends on the signal quality. It is ideal for TVs, movies and video presentations.
Other Functions
Some wireless HDMI extenders support one-to-many applications. For instance, you can distribute one video source from one transmitter to the two TV sets that are connected to two receivers. Some wireless HDMI extenders support multiple one-to-one applications, which means you can deploy several units of transmitter and receiver in the same house simultaneously. With powerful wireless HDMI extenders like AV Access HDW200, you can deploy up to 5 independent pairs in the same zone without interference. Thus, you can build a complete and robust wireless system to easily extend your HDMI sources to the far-end display devices.
That’s all for the buying guide on a wireless HDMI extender. Since we have learned about the above key considerations, now it is pretty simple to choose the right one. The most important factors you need to consider are as follows: the total range of the HDMI signal, the maximum video resolution it supports, the difficulty of installation and transmission latency. The rest is mostly a matter of detail.
