No signal over HDMI cable: how to solve the problem

Nowadays, monitors, laptops, TVs and computers are connected to a transmitter such as a computer or a Blu-Ray player via HDMI cables. However, sometimes you get an error message that no signal can be received via HDMI cable.

Why is there no signal over HDMI cable?

HDMI is a standard used for simultaneous transmission of image and sound over a cable. Since it is a multimedia standard, the transmission should not usually have any problems. However, it can happen that the HDMI cable cannot pass a signal back and forth between the two devices. This grievance can have several causes and can usually be fixed quickly. In most cases, it is just a loose contact.

1. Frequently, a cable that is too long is the cause of all evil. Try to transmit the picture and sound via WLAN. To do this, simply use a WLAN adapter such as a Chromecast or the Amazon Fire TV stick on the TV.
2. If you use the HDMI cable on a PC, then make sure you have the latest graphics card drivers installed.
3. The same applies to a TV. Here you should make sure that you have downloaded and installed the latest driver software. Even with the receiver, this may be the reason for the problem.
4. Of course, the HDMI cable may also be defective. Um dies zu testen, sollten Sie versuchen, ein anderes HDMI Kabel zu benutzen und zu schauen, ob es damit geht. Wenn es funktioniert, war tatsächlich ein defektes HDMI-Kabel das Problem.
