In this review we will talk about the Yehua Wireless HD: transmitter and receiver to wirelessly transmit the HDMI video signal
The audio / video signal, carried by the famous HDMI cable, is one of the most complex and heavy signals. Suffice it to say, in fact, that only a few years ago we were able to find technologies capable of communicating this data wirelessly, without wires. Today we have the pleasure of reviewing the Yehua Wireless TX e RX Kit. It is a kit including transmitter e receiver capable of carrying your HDMI signal wherever you want. It is a system that does not require an internet connection and is particularly suitable for conferences o home theater. Let's not get lost in small talk and see how he behaved.
Packaging and unboxing | Yehua Wireless HD Review
The packaging is really very simple, consisting of a white cardboard with the product information and, inside, a cardboard box containing the kit. Inside the package we find the transmitter and the receiver (with two antennas that can be mounted). Supplied with a small cable HDMI to HDMI, two fairly long cables USB-A / USB-C per power of the two devices, and the power supply from 5V 2A. Three different grip attachments are also included of the power supply, including that Spanish standard. To conclude, an instruction booklet also available in Spanish.
Technical features
Devices use the protocol IEEE 802.11ac 2.4 GHz and 5 GHz. They are also powered at 5V 2A, although in most cases they are able to feed directly from the HDMI port. A receiver can connect with 8 different transmitters, obviously there is only one in the package. The receiver has the following inputs:
- Headphone jack
- USB-C for power
- HDMI input
- VGA port
The transmitter, on the other hand, has exclusively the HDMI male (which is inserted for example to the PC) and is powered autonomously by the PC. Alternatively, the USB-C input located on the edge can be used. It may happen that the transmitter does not have enough energy to stream (the status LED in this case will flash) then just power it properly through the USB-C cable.
Design and first use | Yehua Wireless HD Review
Let's start talking about the really well done design and premium materials. The transmitter is very small, gray on the sides and black on the top. In the center it has the status light and a button useful to stop and resume the data flow. The receiver is also well made, totally in aluminum, with the key ON / OFF on the right side and the small slot for the reset placed beyond beneath. Obviously, he too has the status LED.
As soon as they came out of the package, I immediately carried out a very basic test, that is to connect them within the same room. So I took out the receiver first, connected the two supplied antennas and connected the cable HDMI to a TV. Right after that I took out the transmitter and simply plugged it into my laptop's HDMI port. Within seconds the devices hooked up and started streaming the PC's HDMI signal directly to the TV. Sometimes this can happen automatism fails, in that case just follow the very simple steps explained clearly on libretto to pair the two devices "manually".
Considerations | Yehua Wireless HD Review
I used the device for a few days, not only bringing the laptop's HDMI signal to the TV within the same room, but streaming to adjacent rooms as well. The manufacturer declares a maximum range in the presence of walls between the two devices 10 meters. In open spaces, however, the range becomes about 20 meters. I can roughly confirm the measurements declared by the manufacturer. I found the device great for streaming video, or perhaps viewing some document. It is great, for example, to transfer the images of one conference from a PC to a TV or to a projector of a meeting room.
There is input lag, and even at very small distances it is felt. It is evident like this cannot be used for video game streaming, at least all those that require quick reflexes and low input lag. However, in the streaming of the monitor, documents or Power Point presentations experience it's more than that enjoyable. The audio also manages to pass very cleanly and there is no delay in synchronization between audio and video (very important factor).
Conclusions and prices | Yehua Wireless HD Review
I found this Yehua Wireless HD Kit particularly performing and very suitable for uses of office o Pets. Really very simple to connect, extremely intuitive (in my case, literally nothing was needed except connecting the devices), and from the professional design and not cheap at all. A product that I therefore feel I can recommend despite the price slightly tall, but which I am sure will solve various problems in the home and professional environment.
