HDMI is a commonly used abbreviation for High Definition Multimedia Interface. It allows the homeowner to avoid constant plugging and re-plugging of wires. HDMI switches are also known as HDMI switchers or HDMI switching boxes. These switches are the so-called ‘hubs’ for your home theatres audio/video. Generally, these cables and switches will not cause connection issues. Refer to the commonly issues given below and clear out the problem.
I cannot connect the cable to my HDMI port
It is important to ensure that the cable version is appropriate prior to connecting it into the port. Refer to the manual of your display device and verify the version number supported by the HDMI port. HDMI ports are available in four different versions. Each of these versions consists of different ‘Magsafe’ ends.
I do not get any sound from the video
In such a scenario, ensure that the cable is properly connected to your display device. Disconnect the cable, clear out any dirt or dust and reconnect. If the issue persists, check the video card specifications of your transmitting device. If it does not consist of a single HDMI port, you will need to purchase an adaptor. If you still face the problem, return the cable and opt for a newer one.
The HDMI switches do not work well with all my devices
This problem is known to affect most DVR owners. This is because the DVR never powers off and hence it will not release the HDMI switch automatically. Therefore the HDMI cable might not get recognised the next time when you plug it in. Some switches support port prioritisation, which can solve the problem. The port prioritisation switches gives priority to the device on input 1 over input 2. This means that if you have a DVR on input 2, and turn on the Blu-ray player on input 1, it switches. When you turn off the Blu-ray player, it reverts back to the DVR.
