A wireless HDMI transmitter has been around for several years, but it had problems moving to mass production. Even today, not all manufactured models are widespread in the world, although data exchange technology is advanced.
Transmitter manufacturers promise buyers wireless video with a resolution of 1080p or higher on the TV without any noticeable delay or loss of quality. This brings users one step closer to getting rid of all cables lying around audio and video systems.
Technology description
The HDMI Wireless Transmitter is a generic name for transferring high-definition video and audio from a source device, such as a Blu-ray player, computer or game console, to a wireless TV.
This is a literal replacement for the standard cables that currently connect all media devices. All that is needed is to connect the transmitter to the port on the source device, and the receiver to the connector on the TV, and you're done. There is no setting or configuration. The two halves automatically detect each other and are connected using the wireless communication protocols established by the manufacturer.
The receiver and transmitter may need power cables, but some of the newer models receive power directly from the devices to which they are connected. The range of wireless communication depends on the technology used, as well as on the location of the TV and source devices. Usually it is from 10 to 30 meters, and in some cases direct visibility is required.
Most HDMI wireless products also include infrared ports and keys that allow you to control the source device even if it is in another room. Wireless game controllers can also be used.
4 reasons to use the device
The main advantages of the HDMI wireless transmitter are convenience and no interference. In addition, the main reasons why people purchase these modules include the following points:
- When switching to wireless communication, we can say with confidence that the wires on the TV decrease significantly. It’s especially convenient to use the transmitter if all the video devices are placed on the wall.
- If you need to broadcast an online movie from the console in the bedroom to the TV in the living room or connect a projector in the office meeting room, you can do this in a matter of minutes. There is no need to place the devices next to each other and no need to lay long cables to connect them.
- Most TVs have at least two HDMI ports, but this is not always enough. The good news is that some wireless receivers have multiple input ports, so you can easily connect additional sources. Modern models are capable of transmitting broadcasts to several TVs.
- There is embedded software. It supports working with all popular mobile and PC platforms. This allows you to quickly adjust the video resolution and adjust its basic parameters.
The wireless module is not Chromecast equipment or other related streaming device. The main objective of such a system is the transmission of information from one source to another.
Beginning of work
The developers have built a mini-operating system into the HDMI transmitter. This makes it possible, when connected to any TV model, to quickly unload drivers and synchronize to work.
All you need to do to get the transmitter to work is:
- Connect the modules to the ports.
- Turn on the TV.
- Select HDMI operation mode.
- Wait until a signal appears.
Setting the data transfer speed and screen resolution is only possible through a mobile device or PC. However, not all models support these options. Before buying, you need to clarify whether there is software support and settings for streaming video and audio.

- Data transfer technology. HDMI wireless transmitters currently use Wireless HD, WHDI, and Wi-Fi technology. Each of them has its own advantages. You must choose the one that best suits your needs and supports high quality video and sound. WHDI is more efficient when streaming.
- Working range. Make sure that the device meets the operating or functional range. The stores feature models with a range of up to 300 meters.
- Video quality, audio and delay. Do not compromise video or audio quality under any circumstances. It’s better to choose a budget but powerful option with additional features such as 3D playback and enhanced sound quality. Low latency transmitters guarantee high quality video streaming.
- Interfaces and compatibility. You must make sure that the wireless transmitter is compatible and can work with devices with different interfaces. Additional features such as MiniUSB and USB ports can improve connectivity and expand the list of synchronizations.
