Techly IDATA HDMI WL50D - Compact Wireless HDMI Review

TECHLY IDATA HDMI WL50D: Compact Wireless HDMI

Techly recently introduced a remarkable wireless extender for HDMI signal, which achieves a range up to 50 meters with eye contact.

Techly's wireless extender IDATA HDMI-WL50D includes 2 transmitter and receiver units, which allow HDMI signal transmission and expansion up to 50 meters. The system uses a frequency of 5 GHz, which achieves better protection from any interference, while supporting point-to-point connection.

An important advantage is that the system allows the transmission of remote control commands (IR pass back) through the wireless connection channel, in a frequency range of 20-60KHz. This means that both the transmitter and the receiver have an IR socket for connecting the sensors provided for receiving and transmitting infrared signals.

This is a great solution for meetings, conferences, home entertainment and educational multimedia, as it removes cables and distance restrictions between the HDMI source and the screen.

According to the manufacturer, for the maximum quality of the wireless connection at 5 GHz, obstacles such as walls or glass should be avoided, as they can create strong signal losses. Therefore, the system should work with full eye contact between transmitter and receiver.

HDMI1.3 with HDCP1.2 is supported on HDMI connection and therefore the highest possible resolution is 1080p Full HD. In addition, the latency observed is less than 200 ms, which is practically not immediately noticeable.

Connections

The set includes a transmitter (Tx) that looks like a large usb stick and the receiver (Rx), at which an adjustable antenna (provided) is connected to receive the signal. The transmitter has a 5 V power input (with usb cable provided), HDMI input, which is a male plug built into the Tx boat, and a socket for the IR blaster cable provided to carry the remote control. The power can come from an available USB port on a device or from a mobile phone charger.

The transmitter also has 2 LEDs, one for power and one for HDMI or data transmission. In case of smooth data transmission, the red LED flashes.

The receiver has a power input from the supplied power supply, an HDMI output and a socket for the supplied IR sensor, which receives the IR commands of the remote control and integrates them into the IR pass back.

Also, the receiver has a green LED for wireless connection, which in connection conditions connects permanently and also a green LED which when attempting to connect flashes slowly, while when connection is achieved and data is transmitted, it flashes quickly.

Installation 

The set does not require any kind of setup, not even some kind of coupling, as with the power supply and HDMI connections we have an immediate picture, provided of course the signal adequacy.

We recommend that you first simply connect wirelessly and then install the IR sensors, which have the appropriate marking with tape to avoid the opposite placement.

Tests 

First, we placed the two units at the maximum possible distance of 20 meters in the test area, with full visual contact and the connection was made immediately without any problems.

We then placed the transmitter in an adjacent room at a similar distance, but without eye contact and the connection - as expected - was marginal with freezes. In this way we simply confirmed that visual contact is indeed required for seamless wireless connection.

The IR pass back has worked perfectly, with infinitesimal lag, so it is not immediately apparent that it is a remote device.

Finally, the picture and sound quality were excellent.

Our opinion

After several tests, we can argue that the TECHLY IDATA HDMI-WL50D Wireless Extension HDMI Set is a serious system for quality HDMI image and audio transmission, which is good to use with visual contact of Tx and Rx, especially as it increases the distance.
