[Updated February 2024] Wireless HDMI is the generic name for transmitting HD video and audio from a source device — such as a BluRay player, a PC computer, or a gaming console — to a TV without any wires. The majority of the high definition wireless transmission technologies use radio frequencies which range from 10 GigaHertz to 200 GigaHertz.
There are numerous brands that now manufacture wireless high definition products & devices to take advantage of this technology.

Buyers Guide to Wireless HDMI
- Many video compression schemes which use HDMI work over 802.11n and other similar wireless interfaces.
- The consumer brand Asus also supplies HDMI products they call WAVI (Wireless Audio Video Interaction). A wireless HDMI which uses 4 x 5 Memory In and Memory Out (MIMO) channels.
- Wireless High definition televisions known as WiDi are also being manufactured with the aid of wireless HDMI technology and Toshiba is one the first companies to build this kind of television.
Some of the major benefits of wireless HDMI are:
It’s easier to setup
Running cables may still be a way that many people do business, but it’s a real pain! If you’re trying to cover breaking news, you may not have time to run a bunch of hdmi cables just to get a signal. Or, if you’re shooting video in a crowded spot, having a bunch of hdmi cables everywhere could make things downright dangerous.
Instead, with a wireless HDMI transmitter, all you have to do is turn your camera on and start shooting. Luckily, these devices are strong enough to transmit through walls and ceilings, so you’ll never be left searching for a signal. You won’t even need a power cord for the transmitter itself! Does it get any easier than that?
Pocket-friendly budget
Just a few years ago, the terms “wireless HDMI transmitter” and “affordable” didn’t go together. Up until recently, this equipment was reserved for people with deep pockets. If you were just an average joe, you couldn’t afford to tap into the power of this technology.
Luckily, times have changed. Today, a good transmitter will fit into just about any budget. Many retailers have them available and will provide plenty of technical support so you can work out any kinks free of charge.
It’s light as a feather
It may seem hard to believe that all of your HD and SD videos can be transmitted with a tiny piece of equipment, but it’s true! A good wireless HDMI transmitter weighs less than a smartphone, which means you can feel free to stick it in your pocket and carry it with you anywhere.
Offers the best quality
When it comes to audio and video, HDMI is as good as it gets. The video itself is “uncompressed” — which means it looks cleaner and less processed than other videos. Because a wireless HDMI transmitter can send video without compressing it, you’ll never have to worry about your video looking anything other than crystal clear. In fact, a good transmitter can handle the high-definition video formats (including 1080p), so you can rest easy knowing that your finished product will be as crisp and as lifelike as it gets.
It doesn’t just send information
The best wireless HDMI transmitters do double-duty — by receiving audio and video, too. You don’t need a degree in rocket science to figure it all out. Instead, if you know how to use a remote control, you can get this equipment up and running.
It won’t give you any interference
Thanks to something called “dynamic frequency selection”, you won’t have to worry about noise making an appearance in your video. That’s because a good transmitter will automatically search for a wireless frequency channel with a low interference level. In other words, it will scan for the best channel to send and receive video on, so that your finished product doesn’t look like it was shot in the Stone Age!
Why do we need wireless HDMI transmitters?

What Features to Compare when looking for wireless HDMI
Data Transmission Technology
The data transmission technology is an important parameter when you are selecting a wireless HDMI device. As of today, WirelessHD, WHDI, and WiFi are used most often. The differences between these types lie in the operational frequency, the distance the device is able to transmit the signal and the ability to pass through obstacles.
WirelessHD is able to transfer video and audio in high quality but the transmission range is limited, especially if there are obstacles involved. At the same time, both WHDI and WiFi transfer data between rooms through walls and sometimes even ceilings just fine but in some cases, a bit of quality might be lost when the distance is too large or the obstacles are too thick.
Video and Audio Quality
Although for quite some time the manufacturers have been feeding us promises that the technology for 4K video wireless HDMI transfer will be developed soon, today the best video quality we can get from these type of devices is 1080p.
Moreover, among wireless HDMI models, you can find those supporting 3D, which is a dream come true for many movie lovers and gamers. And as for the audio, the best quality available is 5.1 or even 7.1 uncompressed surround sound. Look through the specs to see if the model you have chosen supports this signal quality.
Note that this device is not designed to increase quality but only to transmit the signal as clearly as possible. If you are streaming music from your smartphone, for example, the sound will be based on your smartphone specs.
Operating Range
Operating range is essentially the maximum distance between the transmitter and the receiver that will not result in signal loss or image/sound quality decrease. If you are going to set the transmitter and the receiver far from each other or on different floors, for example, you should look for a device with an operation range of 100ft or more. For using them in the same room, you can get a 30ft range model.
Interfaces and Compatibility
How does a wireless HDMI work? Usually, all transmitters and receivers in a set have HDMI inputs and outputs, to send and receive signals respectively. The more ports like this the set has, the more gadgets and devices you will be able to connect. Mini-USB and USB ports are often provided for maintenance and sometimes you will also find a 3.5mm jack or other port to plug your headphones in.
And, of course, there are charging ports. As for a wireless HDMI connection, you should follow these simple rules. When you connect wireless HDMI to your PC or mobile device, it is necessary to check the operating system installed on that device. With other gadgets, however, wireless HDMI is more versatile. If the device has an HDMI port, chances are it will work with wireless HDMI without problems.
Everything isn’t perfect yet
Wireless HDMI transmitter is not yet advanced enough to be used in much larger areas such as open office or malls so usability is somewhat restricted.
