Hollyland MARS 300 PRO

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.

Review of Hollyland MARS 300 PRO Wireless Video Transmission System

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.

What do You Know About HDCP?

Today all manufacturers of wireless video senders are regarding signal protection matter a very important one. For that purpose, the majority of companies use the High-Bandwidth Digital Content Protection (HDCP) protocol. This protocol was engineered by Intel and serves as a tool to control and manage digital data access via DVI and HDMI interfaces.

The intended purpose of the HDCP is to prevent the transfer of unencrypted high-definition audio and video signal. However, Intel as the license holder charges the HDCP adopters a license fee. Nevertheless, all manufacturers of high-definition audio/video receivers are obliged to use this data protection technology by a special US law. As a side note, the HDCP support is mandatory for devices to achieve conformity to the requirements of the HD ready certificate. In conclusion, other than being a splendid option for transmitting a high-quality video signal, this product also provides an effective transmission of a quality sound signal. Moreover, the device has gained the FCC, ICE, CUL, and UL international certifications.

Wireless HDMI - Nyrius ARIES Prime Review
 

Measy FHD676

200 Metres Transmission Range

The Measy FHD676 is an odd-sounding name, though there's nothing odd about these devices. Quite the opposite, their parameters are strong across the board. You can start practically anywhere with this package and you'd be highlighting its noticeable superiority among comparable wireless HDMI transmitters and receivers within the same price bracket, so we'll use the maximum range as the springboard.

Reaching 200 metres (more than 650 feet), the model covers sizable conference rooms and the biggest houses, so you can do without long HDMI cables extending video signals. Different scenarios have different needs but, as far as we're aware, there are no scenarios where 200 metres is insufficient.

Of course, at 100 quid, this device offers Full HD (1920 x 1080p) wireless transmission. What's more, the model can transmit Full HD footage at 60 fps. Compressing and decompressing H.264 video, this device transfers the footage with efficiency, ensuring high playback fluency with the high-bandwidth digital content protection tech covering its six.

Not unlike its less expensive competition, the model offers digital 5 GHz frequency wireless audio and video transmission. And, needless to say, it is compatible with HDMI 1.3 and HDCP 1.2, which is something that wireless HDMI transmitters and receivers nowadays are not complete without.

Review of Measy FHD676 Wireless HDMI

Infrared Approach

The model comes equipped with 2 external antennas on each side, hence its fantastic coverage. However, to go with these external antennas, the Measy FHD676 also offers 20-60 kHz wide-frequency infrared coverage. Using the IR cables that are shipped with the package, you'll be able to control HDMI-source devices (like Blu-ray players) at a remote location, 'manipulating' them from a different room.

Is the product flawless? No, none are. Its biggest flaw is not the price though. Sure, some people might feel like 100 quid is pretty steep, but this is actually quite reasonable considering the specs. The biggest problem we have with this device is that the signal will occasionally drop after some time of inactivity. It is not the worst problem you can have with wireless HDMI transmitters/receivers but a problem nonetheless. What's not a problem is that the same signal will remain smooth even through a wall or ceiling (assuming they're not very dense).

All things considered, when transmission range is a top priority, you cannot go wrong with Measy FHD676 and its no-compression, no-delay performance.

AT-Mizhi (WXJSQ0330)

The Smallest 4K-Capable Extender

The AT-Mizhi wireless HDMI display adapter is yet another dongle-like HDMI extender that can be used with a wide variety of different monitors, digital screens, and TVs. That being said, compactness is merely a feature of this model and not its main selling point.

The main factor that makes this affordable HDMI extender valuable among other products included on our list is, of course, a 4K (3840 x 2160) resolution that puts it miles ahead of simple Full HD. But how exactly is it capable of transmitting such a high resolution without issues? Well, that is where we need to take a look at what is inside of the unit.

When you take a first glance at the transmitter, it doesn’t look like there’s much going on. However, that first impression is deceiving. The main thing that separates this particular dongle from the competition is the Wi-Fi support that gives it an edge when it comes to data throughput and how much more it can process in seconds. This wireless module enables the receiver to broadcast the high-quality video feed directly to large TVs and screens without a hitch.

Review of AT-Mizhi (WXJSQ0330) 4K HDR Wireless HDMI Display Adapter

Compact and Powerful

Another thing that is convenient here is the size of the whole package. Measuring only 21.2 x 15.6 x 2.3 cm in size, the device is extremely compact, light, and easy to carry around, which makes it an optimal choice for presentations or for a TV cinema projector. Likewise, the device will work excellently with laptops and computer monitors that feature an HDMI port.

Compatible with both Android-based phones and iPhones from Apple, the AT-Mizhi can be used to broadcast media directly to your TV, computer screen or laptop monitor with ease. What is really good about this setup, however, is that it doesn’t require you to install any external applications. 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. So, if you are looking for the best bang for your buck, there is little doubt about it - the AT-Mizhi is the right model for that.

Eadidi Cast-123

No Freezes

The Eadidi Cast-123 costs virtually nothing. At less than 15 quid, this device boasts pretty uncanny specs and features. Before we discuss these features, however, let's address its footprint.

Including the supplied USB cable, the model measures 10.7 x 10.6 x 2.2 centimetres, which's fairly modest. In the same vein, this device weighs 70 grammes, so you can drop it in the bag/backpack and not even notice that it's there. We also like its shape, with the rounded butt preventing the dongle from scratching fragile surfaces. But we're not quite as enthusiastic about the aforementioned USB cable. Because it is as short as it is, you will sometimes feel a little tied.

The HDMI output, on the other hand, is tight but not unnecessarily tight, which means that you can insert and remove it with ease but also that the dongle will not be detached accidentally. There's a small external antenna stretching the model's coverage range 10 metres. Whilst 10 metres is not necessarily unheard of, considering the dongle's size and the fact that the antenna is practically nonexistent, the fact that its range is 10 metres and not 5-8 metres tops is pretty impressive.

What's also pretty impressive is the dual-core processor that this device comes outfitted with. Thanks to this processor, the model receives a signal without compression and without delay, displaying even high-bitrate footage with multiple sound channels through DLNA without introducing freezes.

Review of Eadidi Cast-123 Wireless HDMI Display Adapter

Screen Reflection

Again, taking the modest price into account first, there's virtually nothing disappointing about the dongle's performance. Besides DLNA, the model supports Airplay. With Full HD (1920 x 1080p) video, this device also offers screen reflection. Whilst the model does not support screen reflection with Ultra HD (3840 x 2160p) footage, the fact that this dongle is compatible with 4K content is quite impressive in and of itself. Furthermore, this content can be coming not just from Windows devices but also Android, iOS, and macOS. Furthering its cause even more, the model's housing is excellent at dissipating heat, preventing the internal components (including its circuitry) from overheating.

In closing, with the Eadidi Cast-123, you can share PPTs, emails, documents, as well as other content with colleagues without wires. You can also view photos from a phone on a large-screen TV or use streaming surfaces even if the TV doesn't include Smart features.

What Is a Wireless HDMI?

As many of you probably know, an HDMI cable is needed to provide a transfer of 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? For example, they can be placed on different floors or in different rooms, and connecting them by wires would simply be impractical. A wireless HDMI system (also called a video sender) will be a perfect solution for you to use in that case. 

This video sender, more often than not, consists of a transmitter and a receiver to transfer images and sound from your PC, Blu-Ray player, console, or gaming station to the TV screen, monitor, TV projector, or any other similar appliances. Standard HDMI extenders usually use a Wi-Fi connection, which is powerful enough to handle a Full-HD resolution and, in some cases, even 4K with ease.

If you still have problems with regards to numerous HDMI cables for your equipment, we recommend that you pay attention to one of the HDMI Switchers & Splitters we've described in our other review.

What else you may want to acquire is a quality projector or a new cutting-edge TV-set that will free a lot of space in the room.

What Features to Compare

Data Transmission Technology

When choosing a wireless HDMI system, we recommend considering the type of data transmission technology. Currently, most of the manufacturers use the following types: WirelessHD, WHDI, and WiFi. The main difference between these technologies is their operation at different frequencies, provided transmission range and their ability to transmit signals through objects and obstacles. The WirelessHD technology can transmit high-quality video and audio, but it has a limited transmission range; thus it usually requires minimum obstacles located between the transmitter and receiver. In their turn, WHDI and Wi-Fi technologies are perfect for signal transmission throughout the house owing to a higher transmission range supported and the ability of their signals to penetrate through walls and other objects on their way. However, you need to take into consideration possible signal power loss and thus visual quality degradation because of the signal transmission 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 plan to use your HDMI kit to provide video and audio data transmission between devices located on different floors or at a large distance, then we suggest looking to video senders with an operating range of 100 feet or more. If your source and receiver are located close to each other and there is no need to space them far apart, you can easily choose 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 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 3.5mm ports for your headphones. It worth mentioning that pairing source devices with receiving ones using the kit maybe 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 a source the OS installed is not that important as video senders can be used with almost any devices supporting a wireless HDMI connection.

FAQ:

Q: What is a Wireless HDMI?
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 that implement this technology. These devices are manufactured as data senders (sources) or kits including a data sender and a receiver. The senders are equipped with one or more HDMI inputs to source the original signal and provide a synchronisation with receivers, which in their turn are equipped with an HDMI output to connect to output devices. 

Q: What are the benefits of using Wireless HDMI devices?
A: As it was mentioned the main benefit of using a Wireless HDMI data transfer is that one does not need to lay out cables to connect a source to a receiver. In some cases when there are many cabled devices around laying cables may be inconvenient. However, when you need to transfer an HDMI data stream from a source to a receiver, which are located two or more dozen metres from each other using a cable connection may even result in signal quality degradation. For such cases, the wireless transmission is the optimal and sometimes only solution.

Q: Are various Wireless HDMI devices may have different performance?
A: Yes. Though all these devices use the same principle of wireless transmission of a data stream, they may implement different wireless technologies to perform this task. With Wi-Fi being the most commonly used transmission technology, there are models that use proprietary radio technologies with a higher carrier frequency, such as GigaXtreme, WHDI, HDbitT, and others. These technologies are customized to the manufacturer’s needs, which may be a higher data bandwidth, capability of transmitting the data to two or more receivers from a single source, etc. Therefore Wireless HDMI devices mostly differ in maximum range (usually up to 30 metres) and bandwidth of data transfer. The maximum bandwidth supported defines the list of video formats a certain device can transmit. For example, transmission of 1080p or FullHD video requires higher bandwidth than 1080i or 720p. Thus, you need to check the supported video formats with the device specifications.

Q: Are there any other differences Wireless HDMI devices?
A: First of all wireless HDMIs are produced in different sizes ranging from quite bulky (almost of a gaming console size) to very compact and portable ones, which you can carry in your pocket (as small as a USB thumb drive). These devices may also have additional manufacturer-specific features.

Q: Are there any limitations of Wireless HDMI to wired HDMI transfer?
A: The main limitations for this type of devices and the technology, in general, are transmission range, data transmission bandwidth and a number of receiving devices a source can transmit the media stream to and synchronise with at once.
