The CHIP test center evaluated these products.More info.The wireless HDMI transmitter reduces cable clutter.With a wireless HDMI transmitter and receiver, you replace the cable to the TV.WLAN and Bluetooth already offer a lot of flexibility if you want to network mobile devices and home electronics.The HDMI cable quickly transfers large amounts of data between the Blu-ray player and game console to the television.You need special technology to replace this cable: Wireless HDMI adapters allow data to be transmitted wirelessly.The Digitus DS-55314 model is our top recommendation.The transmitter for around 220 euros allows excellent transmission of full HD videos.If you want to see UHD content, you have to spend a little more: We recommend the Purelink CSW200 for around 250 euros.We also have a price-performance tip ready.We tested 8 wireless HDMI adapters in our test lab and last updated the test results in September 2020.We checked the offers for you in April 2021.The dealer may pay a commission for links on this page, eg for links marked with or green underlining.More info.Possible recipientsPossible recipientsOverall grade: very good (1.3) The wireless HDMI transmitter Digitus DS-55314 offers the best picture quality, even over long distances, and very good equipment.The Digitus DS-55314 is the best wireless HDMI transmitter in the test.Overall rating: good (1.9) The wireless HDMI transmitter Measy FHD676 can ensure very good image quality even for little money, but the equipment is limited.The Measy FHD676 wireless HDMI transmitter offers good performance at an affordable price.Overall rating: good (1.9) The Purelink CSW200 is a wireless HDMI transmitter that you can also use to transmit Ultra HD films, and it also offers low latency.With the Purelink CSW200 you can also transmit UHD films wirelessly.The wireless HDMI transmitter converts the cable signal into a radio signal.The wireless HDMI transmitter comes with advantages and disadvantages.The wireless HDMI transmitters partly differ from each other in how they work.The CHIP test center tests the wireless HDMI transmitters in terms of performance, equipment and energy efficiency.The transmission quality is tested in stages: transmitter and receiver are placed at increasing distances from each other, both with a direct line of sight and with obstacles, in order to then assess the picture quality on the television.All transmitters should be able to handle a range of 5 and 10 meters, but interference can occur at greater distances (20 or 50 meters).This depends in part on the radio frequency used, but also on the quality of the radio antennas.The performance accounts for 60 percent of the overall grade.In addition, the experts at the CHIP test center assess the equipment in terms of connections, functions and supported formats.This accounts for 35 percent of the final rating.The remaining 5 percent is accounted for by the evaluation of energy efficiency.For this purpose, the power consumption is measured in Full HD mode and in standby.This results in the overall grade in the range from 1 to 6. We test fairly and independently.The best wireless HDMI transmitter in the test is the Digitus DS-55314.It offers a strong performance, but costs around 220 euros.You can get away cheaper with the good Measy FHD676 for around 120 euros.If you want to transfer Ultra HD films, we recommend the Purelink CSW200 for around 250 euros.A radio transmission of the video signal is possible with a wireless HDMI transmitter.The devices transmit either in the 5 GHz or 60 GHz frequency band.The differences are in the range, from 10 to 100 meters, and in the data rate.4K films can also be transmitted in this way.The HDMI interface (High Definition Multimedia Interface) is primarily used to connect televisions to playback devices and computer displays to PCs.It is a standard for the simultaneous transmission of image and sound data.This can be done with a cable or wirelessly.
