There are a lot of small details to consider when designing perfect home theater settings, but an important question is how the video really gets on the screen.

Projectors, in particular, are located on the other side of the room with the screen, usually away from the cable or Internet connection.
The idea of connecting them all through wires on ceilings and walls is daunting.

However, there is one solution that can save you a lot of time and hassle: a wireless video receiver!

The best way to transmit video wirelessly is to use a wireless HDMI transmitter / receiver or through streaming rods such as Chromecast or Roku.

For wireless HDMI, simply connect the transmitter and receiver to your source and destination.

This covers the basics, but now I'm sure you want to know which of these two options is better?

These two options have their own advantages and disadvantages, so let's take a closer look at which one is best for you.

First of all, it's best to know about the actual hardware.
How Wireless Video Devices work.

First, we should talk about wireless HDMI.

No matter what brand and model of wireless HDMI transmitter kits you get, they will send high-quality video signals wirelessly, which can also be done through the projector (our guide).

The kit will be equipped with two pieces of physical hardware: a receiver and a transmitter.

Wireless HDMI Kit-receiver.

The receiver is usually small, perhaps the size of a deck of cards, or, in a more expensive version, as small as a bulky USB drive.

What the receiver does is decode the video signal and convert it into a HDMI output signal.

The signal is then fed into the monitor or projector like a normal HDMI port.

The receiver is usually small enough to hang on the port, but in some cases the receiver may be slightly larger, requiring your own installation solution near or on the projector, and using a short HDMI cable to make the final jump from the receiver to the projector.

Because the receiver is decoding the information into a HDMI signal, some important processing is under way, and the receiver will need a power connection, so be sure to understand the power requirements of the kit in advance.

For example, if it comes with only an AC wall adapter, you may cause yourself another problem.

After all, if the projector is installed on the ceiling, you may not have a convenient plug.

However, most wireless HDMI kits can be powered over the USB cable, so carefully check that your projector has an open port for this purpose.
