Our pick
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 over $50 and get the Nyrius Aries Home instead.
Runner-up
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.
Budget pick
If you’re looking for an easy, affordable way to wirelessly transmit an AV signal across a room—perhaps from a Blu-ray player to a front projector that’s mounted on the back wall or the ceiling—we recommend the Monoprice Blackbird Pro 16049.
This system has been our budget pick for years, and a recent upgrade added the ability to transmit 4K video signals—but only up to 30 Hz and not in high dynamic range. While the description on Amazon’s product page does not articulate this upgrade, Monoprice’s own website clearly does so, and our most recent round of tests confirmed it.
The Blackbird Pro’s wireless technology differs from that of our other picks and requires line-of-sight between the transmitter and receiver, so this system works only as an in-room option. Any obstructions sitting between the two boxes 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.
