The Best Wireless HDMI Video Transmitter 2025
Sometimes it’s not convenient, or even feasible, to run an HDMI video cable between your video player and your TV or projector. A wireless HDMI video transmitter solves that problem, allowing you to send an AV signal wirelessly across the room or through walls to another location.
A good wired setup will always be more reliable, but if you need wireless transmission, we recommend the Nyrius Aries Home+ because it performs well and has more features than the competition.
There’s nothing worse than sitting down to watch TV and having the video signal freeze, flash on and off, or disappear entirely. Unfortunately, that’s what you get from many wireless HDMI video transmitters, especially if you’re trying to send the AV signal over a long distance, through multiple walls. In our tests, the Nyrius Aries Home+ consistently delivered the most stable, reliable wireless signal and offered great picture quality overall.
Plus, this system boasts the widest array of features, including support for 7.1-channel surround sound (most of these systems support only stereo audio) and the ability to power the receiver unit through your TV’s USB port so you don’t have to plug it into a power outlet. The transmitter has two HDMI inputs to connect multiple sources at once, as well as an HDMI output to pass those signals through to a nearby TV.
Because the Aries Home+ is so full featured, it costs more than most competitors. If you don’t need the HDMI output and the second HDMI input, you can save $100 and get the Nyrius Aries Home instead.
Runner-up
This model is a reliable performer, and you can change the wireless channel as necessary to improve performance. But it passes only stereo audio and isn’t as user-friendly.
If the Nyrius Aries Home+ isn’t available and you need to pass only stereo audio (as opposed to surround sound), the J-Tech Digital WEX200V3 is a great alternative for sending AV signals around the home. This wireless HDMI system performed almost as reliably as our top pick in our tests, and we didn’t see a lot of signal freezes or dropouts.
The WEX200V3 is the only system we tested that lets you easily change the wireless channel (the frequency it’s using to transmit the signal) with the press of a button, so it’s good for use in areas with a lot of potential interference.
J-Tech Digital aims its devices at the professional and custom-installation markets, and the WEX200V3 definitely has a “pro” look, consisting of metal boxes, big antennas, and proprietary, lockable power cables. Because of that last feature, you can’t power this system’s receiver via USB, as you can with our top pick.
Best for…
This system can wirelessly transmit a clean 4K signal across a room, but the technology doesn’t work through walls or other obstructions.
If you’re looking for an easy way to wirelessly transmit a 4K video signal across a room—perhaps from a 4K Blu-ray player to a front projector that’s mounted on the back wall or the ceiling—we recommend the Monoprice Blackbird Pro 16049. But like most of its competitors, this system supports 4K video only up to 30 Hz and not in high dynamic range. A good wired HDMI setup is still the way to go if you want all the benefits of the Ultra HD 4K video format.
The Blackbird Pro’s wireless technology differs from that of our other picks because it demands line-of-sight between the transmitter and receiver, so this system works only as an in-room option. Any obstructions between the two boxes (including a person walking between them) will cause stability issues. But when the system has a clear path, it delivers a great-looking picture and supports 7.1-channel audio. And you can power both the transmitter and the receiver through USB, so you don’t need to position them near power outlets.
