![]() The chromecast icon on your phone or laptop creates the illusion that you are “sending” video to the streaming stick when you control it, but what you are actually doing is directing the small computer in the streaming stick to go and access the video content you select from the internet (a server at Netflix, for instance) and stream it to the screen. Instead, these wireless streaming sticks connect directly to your wireless internet and stream content to the screen as necessary. The biggest difference streaming sticks have from wireless HDMI units is that there is no encoding and decoding of the video signal. They almost always take power over USB, and many of them are perfect for solving the projector-video problem. ![]() These are the Chromecasts, the Roku Sticks, and Amazon Sticks that are sleek enough to plug in and forget. In the last few years, an alternative has emerged that is even more drop-dead simple to use: content streaming sticks. Streaming Sticks Chromecast by EricaJoy is licensed under CC BY-SA 2.0 These are well-understood technology, very reliable, and consumer-friendly. A transmitter and a receiver that encodes and decodes the video on either end. So, you can see that a wireless HDMI setup is pretty simple in the end. When the transmitter is hooked up to the video source–and also a power supply–it will automatically take in the video signal, encode it, and transmit it to the receiver. If you have a cable box or game console on this end, you won’t have any problems, but if you’re planning to transmit from a computer, go ahead and briefly glance at the back and make sure that you have an HDMI port on your video card. No matter where the video is coming from, it needs to be output in HDMI, which is how the wireless transmitter plugs in. Maybe that’s an Xbox, cable box, or a home computer that can be used as a video server. That takes care of the receiver, but what about the transmitter? The other part of an HDMI kit is meant to live at the source of video content. Wireless HDMI Kit – The Transmitter Transmitter for IOGEAR GWHDKITD However, most wireless HDMI kits can take power from a USB cord, so, double-check that your projector has an open port to use for this. After all, if a projector is mounted on the ceiling you likely won’t have a plug to use handy. If it only comes with an AC wall adapter, for instance, you may be giving yourself another problem. The receiver will typically be small enough that it can just hang off the port, but, in some cases, the receiver might be a little larger and need its own mounting solution near to, or on, the projector, with a short HDMI cord making the final jump from the receiver to the projector.īecause the receiver is decoding information into an HDMI signal, there’s some serious processing going on and the receiver will require a power connection, so, make sure ahead of time that you understand your kit’s power requirements. ![]() That signal is then fed into the display or projector like a normal HDMI port. What the receiver does is decode the video signal and convert it to an HDMI output signal. The receiver is typically smaller, maybe about the size of a deck of cards or, on more expensive versions, small enough to resemble a chunky USB drive. The kit will come with two pieces of physical hardware: one receiver and one transmitter. No matter what make and model wireless HDMI transmitter kit you get, they will all send a high-quality video signal wirelessly, which can also be done with a projector (our guide). How Wireless Video Equipment Worksįirst, we should discuss wireless HDMI. First off, it’s best to understand what’s going on with the actual hardware. That covers the basics, but now I’m sure that now you’re wondering which of those two options is better? There are some advantages and disadvantages to both options, so let’s dive in and see which option might be best for you. ![]() For wireless HDMI, simply connect the transmitter and receiver up to your source and destination. The best ways to transmit video wirelessly are by using a wireless HDMI transmitter/receiver or through a streaming stick like Chromecast or Roku. However, there is one solution that can save you a lot of time and trouble here: wireless video receivers! ![]() The idea of connecting it all up through wires in the ceiling and walls is pretty daunting. Especially for projectors, which are on the opposite side of the room as the screen and typically nowhere near a cable or internet hookup. There are lots of little details to think about when designing your perfect home theater setup, but one big one is how the video is going to actually get to the screen. ![]()
