As you add more and more high definition devices to your home theater, you may begin to notice that you are running out of HDMI ports. Most televisions only come with about a maximum of 4 HDMI ports. It is not hard to fill those ports up if you have things like an Xbox 360, Playstation 3, Cable Box, Blu Ray player, etc. So what’s the solution? An HDMI switch will allow you to free up these ports. You can connect the switch to one of the ports on your TV, and then plug all of your devices into the switch. This will allow you to add many more devices to your home theater. Most switches come with a remote so you can easily switch between all of your devices.
Using The Right HDMI cables with your switch
Most HDMI switchers are powered by the HDMI cables and the corresponding devices. Therefore, it is important that you use the right gauge HDMI cable to ensure that you are getting a strong enough signal to get audio and video. The general rule of thumb is to use a minimum of 24AWG cables with runs up to 15ft. Generally, you will need a 22AWG HDMI cable for runs longer up to 50ft. Now, with runs beyond 50ft, a 22AWG cable may work. However, this is more of a hit or miss scenario because it is such a long cable run.
Compatibility
An HDMI switch should in theory be compatible with all HDMI devices. But this isn’t always the case. There is no such thing as an HDMI switch that will be compatible with every single device. It simply does not exist. These devices are pretty finicky when it comes to compatibility. Finding the right device for your set up may take a little trial and error. Most people will get full compatibility the first try.
HDMI switches share a 3 way relationship between the switch, device, and TV. For example, one device and TV will work great with the switch. But maybe not work great with that very same device and another TV. The device, switch, and display all need to play along with each other.
Types of HDMI switches
HDMI switches come in a variety of different configurations. Most commonly, 5×1, 4×1, 3×1, and 2×1 (number of devices x displays). However, there are also HDMI switches that can function as a splitter as well. Meaning you can connect the devices to mirror on multiple displays. The most common of this type of switch is the 4×2 HDMI switch.
So if you need to free up some HDMI ports on your display, get a switch and never look back. Just be sure you are using the appropriate gauge HDMI cable and you will be all set.
Troubleshooting an HDMI switch
If you are struggling to get your switch to work properly, there are a couple of things you can try to pinpoint the problem. Most people automatically assume the switch is at fault. This is often not the case. In many cases, people do not use a thick enough gauge on their HDMI cable and suffer signal loss. If you are using long cables, try replacing them with shorter cables to see if that corrects the issue.
You should also try the switch with different devices/displays.
