We use HDMI to watch high-definition videos and listen to high-definition music.
HDMI, or High Definition Multimedia Interface, is the most widely used signal cable for connecting devices like digital televisions, Blu-ray players, DVD players, PlayStations, and Xboxes. This HDMI cable is used to connect two devices and transport high-quality digital audio and video.
HDMI is also utilized in PCs and laptops since it is a versatile and effective cable. It’s useful when it comes to displaying high-quality movies, such as in educational presentations or retail displays.
Many consumers have claimed that when HDMI is hooked into the TV or any other device, there is no signal. When the TV displays the message “no signal,” it implies it is unable to receive any signal from the external input or the specified signal source.

What source should my TV be on?
Your television’s on-screen input list will normally name it as either TV or ANTENNA if you’re using a coaxial cable. ANTENNA or a version of it, such as ANT, will normally be labeled on the back of the television. When using a coaxial connection, most televisions will need to be set to channel 3 or 4.
Take note of which HDMI input your HDMI cable is plugged into on your television if you’re using one, as most televisions today offer numerous HDMI ports. If your HDMI cord is connected to HDMI-2 on your television, for example, you’ll need to pick HDMI-2 from the on-screen input list to see your picture. As indicated in the input photo above, all of your HDMI ports should be identified with a number (HDMI-1, HDMI-2, etc.) on the back of your TV.
If you’re utilizing component cables, your television’s on-screen input list will normally say COMPONENT or COMP. Some televisions feature numerous component inputs, which should be designated COMPONENT 1, COMPONENT 2, etc. on both your television and your television’s on-screen input list.
If you’re not sure which input your cable box is connected to on your television and can’t check it, you can simply use trial and error by picking one input at a time from the on-screen input list on your television. If one doesn’t work, press the INPUT / SOURCE button again and try another until you find the correct input and your picture returns.
If you know your television is on the correct input but still don’t have an image, double-check both ends of your cords for tightness, as a loose cable can also cause this problem. This problem might also be caused by a faulty cable or port on the television.
