Infrared Frequency setting for HDMI Switch: Are They Useful

HDMI switch is crucial for your devices’ audio-visual applications. Regarding features and specs, HDMI switches come in a wide variety.

Infrared Frequency setting for HDMI Switch One of the essential feature to consider. The definition of infrared frequency and instructions for selecting the frequency best suited to your needs are provided in this article.

Do you need to use an HDMI switch instead, and if so, what infrared frequency setting is best? When utilized with an HDMI extender, the IR signal can pass over the HDMI without altering the default or established Infrared frequency settings of the HDMI cable.

While infrared frequency settings vary depending on the device, the HDMI extender operates uniformly for all devices that use it. Let’s first define infrared frequency and HDMI switch for better understanding

Advantages Infrared Frequency setting for HDMI Switch

Using various frequencies on your HDMI switch has several advantages.

  • Ability to move closer to the device: You may need to move the switch closer to the device if you are using a lower frequency and the signal is not reaching your devices.
  • You should move the button away from the interference-causing objects if you are utilizing a higher frequency and the call is being disrupted.
  • If you live in a city, a lot of noise may interfere with your electronics. This noise can be reduced, and the signal can be improved by using a higher frequency.
  • Use a variety of frequencies to find the optimum one for your needs by experimenting with different frequencies on your HDMI switch.

Disadvantages Infrared Frequency setting for HDMI Switch

Using different frequencies on your HDMI switch has a few drawbacks.

  • There may be a requirement for testing: Finding the right frequency for your needs may require trial and error.
  • It can take some time to cycle through all possible frequencies if you have a lot of devices.
  • So you should look in your HDMI switch’s handbook if you’re having difficulties determining the correct frequency.

What is Infrared Frequency?

The infrared frequency refers to the length of the light that the IR remote emits. Despite being undetectable to the human eye, a camera can see this light. The most popular frequencies for HDMI switches are 38 kHz, 56 kHz, and 78 kHz.

For each kind of equipment, which Infrared Frequencies are ideal?

The best frequency for each device depends on its nature and proximity to the switch. For example, if a Blu-ray player is close to the controller. Use a lower frequency so the signal does not need to travel as far. On the other hand, if your TV is farther from the switch, choose a higher frequency to be sure nothing in the room will interfere with the signal.

Setting of the Infrared Frequency on the HDMI Switch Splitter

The conditions necessary to use your HDMI switch splitter with your selected Infrared Frequency are listed below.

  • Use the HDMI Switch Splitter to connect all of your HDMI output devices.
  • When you choose HDMI as your [signal] output, you can choose between using HDMI or UTP for all of your output.
  • If you choose UTP as your signal output, connect the main unit and display directly over an HDMI connection.
  • Connect the main unit’s cat5e/6 cable, the receiver Smart TV or other devices), and the output to the receiver.
  • Then connect the HDMI Switcher splitter to the included 5.5@4A power supply.
  • After that connect the 4 receivers to the 5V@2A power supply wire.
  • Once the Switch Splitter is turn on, all of the connected HDMI receivers will connect to the receiver in town on the device.
  • As a result, a port that is not in use will stay redundant and won’t show an HDMI device when it is select on the receiver.

Setting the Infrared Frequency for an HDMI Switch Using an HDMI Cable Injector and an IR Remote

  • You can check out the remote signal over the HDMI cable injector. Which enables Infrared signals to pass through the HDMI cable if the HDMI switch splitter is too complicate for you.
  • When seeking for a solution to extend the IR remote control coverage and control the HDMI source device that is outside the range of coverage of the IR control, the IR remote extender can help you save money.
  • However, the IR control works if it is within 100 meters or 300 feet of the HDMI source device.
  • Addtionaly the infrared remote extender works with “dual-band IR devices”. 
  • Which enables it to work with IR signals between 30 kHz and 60KHZ, effectively covering most A/V devices in the home.
  • It exploits an unutilized CEC channel on the HDMI cable to transmit the IR signal across the HDMI cable length, which increases the strength of the infrared remote device over HDMI.


It’s now time to wrap up this blog. The frequency of your HDMI switch can be changed if you have signal problems.

It is important to remember that determining the right frequency for your requirements may require trial and error. If you have a lot of devices, it may also take some time to cycle through all potential frequencies.

If you’re having trouble determining the right frequency, you might need to look at the HDMI Switch’s manual. So I hope this article will help you configure the frequencies on your HDMI switch. Please express your worries in the section below.
