Designed for Full-HD Broadcasting
The Hollyland MARS 300 PRO is one of those wireless HDMI models that grabs your attention with their look but in this case, there is a tad bit more to it than just the looks.
To start off, in contrast with other similar devices of the same category, the Hollyland MARS 300 PRO features an OLED screen. which is a bit unusual for a wireless device such as this. Nevertheless, the transmitter has it, and the side screen will conveniently show you its power status, the results of the channel scan, as well as the video input mode and the number of the selected channel.
When it comes to the numbers, the Hollyland MARS 300 PRO has little to no competition, thanks to its long-range transmitter that is capable of transmitting the signals on distances of up to 91 metres without breaking a sweat. Owing to this, the MARS 300 PRO is a good contender for the role of a Full HD wireless HDMI unit that works with multiple formats without any noticeable lag.
As for the actual video output you can select different quality presets from 480p all the way to 1080p with little to no loss in quality. To add more, both the transmitter and the receiver are equipped with a high-powered antenna that enhances an already strong signal in order to eliminate any potential frequency interference. For added convenience, the cooling fan’s speed can be adjusted using the provided controls, which will come in handy when you are recording close to a microphone and silent operation is preferred.
Works From Batteries and Power Outlets
Moving away from the digital specifications of the appliance, it is important not to omit the interfaces included in the package. Firstly, both the transmitter and the receiver feature HDMI outputs, as expected. However, the receiver has 2 HDMI ports and that allows for connecting two screens or monitors at the same time.
Power-wise, both units can be powered via a 6-16 V DC connection that enables the use of 12 V battery packs. Conversely, you can always hook up the gadgets to an AC power socket using a USB adapter and a micro-USB cable. Fortunately, the transmitter and receiver have a built-in micro-USB port.
To wrap things up, the Hollyland MARS 300 PRO is, without a doubt, a professional-grade HDMI transmitter that will be a good option for users that need a device that can broadcast a Full HD signal on great distances without the need to run cables. The stability of the connection as well as its long-range reach makes the MARS 300 PRO a go-to solution for broadcast-related tasks.

Simply turn on the Wi-Fi, pair the appliance with your mobile gadget and you will be ready to stream. The only caveat of the system is that its maximum effective range is limited to only 10 metres.
Last but not least, the appliance supports both 2.4 GHz and 5 GHz wireless bands, which ensure that the transmitted signal won’t be interfered with by other devices or gadgets. Finally, the AT-Mizhi is an excellent budget-friendly wireless HDMI extender that works flawlessly with high-definition TVs, thanks to its reliable connection and 4K resolution support.

What Is a Wireless HDMI?
As many of you probably know, an HDMI cable is used to transfer high-quality digital video and audio data. But what to do if you want to connect devices that are placed at a considerable distance from each other—on different floors or in different rooms—and connecting them by wires is simply impractical? In cases like this, a wireless HDMI system (also called a video sender) will be a perfect solution.
More often than not, the video sender consists of a transmitter and a receiver to transfer images and sound from a PC, Blu-ray player, console, or gaming station to the TV screen, monitor, TV projector, or other similar appliances. Standard HDMI extenders usually use a Wi-Fi connection that is powerful enough to handle Full-HD resolution and in some cases even 4K with ease.
For those of you having a real problem organising piles of HDMI cables we recommend you also pay attention to one of the HDMI Switchers & Splitters that we look at in our other review.
You may also be interested in checking our review on projectors or new cutting-edge TV sets to free up more room.
What Features to Compare
Data Transmission Technology
When choosing a wireless HDMI system, first of all, you should consider the type of data transmission technology used. As a rule, the market offers the following types: wirelessHD, WHDI, and Wi-Fi. What differs them is: the operation at different frequencies, transmission range, and the ability to transmit signals through objects and obstacles.
For example, the wirelessHD technology allows you to transmit high-quality video and audio, but it has a limited transmission range, therefore it is best used in places with minimum obstacles. WHDI and Wi-Fi technologies, in turn, boast a high transmission range and can transfer signal through walls and other objects, making them ideal for large houses. That being said, you should also consider the possible signal power loss when transmitting the signal over long distances.
Video and Audio Transmission Quality
The quality of video and audio signal transmitted is also an important parameter when deciding on a specific wireless HDMI system. We recommend you to make sure that your source and output devices are capable of supporting up to 1080p video resolution for the best visual experience and utilising the full potential of your device for wireless transmission of HDMI stream. It is worth noting that some models of wireless HDMI systems can support 3D video transfer, which will definitely come to liking to many lovers of 3D movies. As for the audio signal, the best devices are those supporting 5.1 and 7.1 channel uncompressed surround sound, which is a de facto standard for the audio of Full HD and Ultra HD movies. With that, HDMI models supporting mobile devices as signal sources perform the audio transmission in the format supported by your digital mobile device.
Operating Range
An operating range is crucial to know when it comes to digital signal transmission from the transmitter to the receiver without the signal loss. If you're looking for an HDMI kit to transmit video and audio between devices located on different floors or at a large distance, then we suggest you opt for video senders with an operating range of at least 100 feet or more. In the meantime, if the source and receiver are located close to each other, and there is no need to space them far apart, you can go for a model with an operating range of up to 30 feet.
Interfaces and Compatibility
Typically, all transmitters and receivers included in a video sender kit have HDMI input and output ports to pair with the source and receiving devices. The more such ports are available on the kit, the more devices it can wirelessly connect. Apart from the main HDMI ports, some models offer Mini USB and USB auxiliary ports, as well as power connectors and 3.5 mm ports for your headphones. It is worth mentioning that pairing source devices with receiving ones using the kit may be not only an issue of physical ports available, but also of the operating system installed on your host/source device. However, if you use a device other than a PC, laptop or tablet PC as the source, the OS installed is not so important because video senders can be used with almost any device that supports a wireless HDMI connection.
FAQ:
Q: What is a Wireless HDMI?
A: A wireless HDMI may either refer to the streaming technology or be used as a collective name for the devices that use this technology. Nowadays, in most cases, the term is used for the devices utilising this technology. These devices are designed as data senders (sources) or kits and include a data sender and a receiver. The senders are usually equipped with one or more HDMI inputs to source the original signal and provide synchronisation with receivers, while the latter are equipped with an HDMI output to connect to output devices.
Q: What are the benefits of using Wireless HDMI devices?
A: The main benefit of using a wireless HDMI data transfer is that it rids you of the need to lay out cables to connect a source to a receiver, something that may come in handy in dwellings that have lots of cabled devices. More to that, it may turn out to be the only option in cases when the source and receiver are placed more than 20 metres away, preventing the degradation of signal quality.
Q: Is it true that different wireless HDMI devices may deliver different performance?
A: Yes, it is. Even though all of these devices work based on the same principle, they may deliver different performance due to different technology used. While Wi-Fi is the most commonly used transmission technology, you can find models using proprietary radio technologies that are distinguished for a higher carrier frequency, such as GigaXtreme, WHDI, HDbitT, etc. What's unique about them is that they are built with specific needs in mind—a higher data bandwidth, capability of transmitting data to two or more receivers from a single source, and so on. Therefore, different wireless HDMI devices may differ in maximum range and bandwidth of data transfer. To know which one will suit you, make sure to check the specs of the device that you plan to connect it to and the supported video formats. For example, the transmission of 1080p or Full HD video requires higher bandwidth than 1080i or 720p.
Q: What are the other differences between wireless HDMI devices?
A: To be honest, not many. Having said that, they can be produced in a wide range of sizes, ranging from quite bulky (almost a gaming console size) to very compact and portable ones, which can be carried in a pocket. Besides that, they may also have some additional manufacturer-specific features.
Q: Are there any limitations of Wireless HDMI for wired HDMI transmission?
A: The main limitations for devices of this type usually are: transmission range, data transmission bandwidth, and a number of devices that can be used to transmit the media stream to and synchronise with simultaneously.
