The message is easy to misread: it usually does not mean that the monitor itself has no power, and it does not prove that the cable is broken.</p> <p>It means the monitor is not receiving a usable video signal on the input it is currently trying to display.</p> <p>That distinction makes troubleshooting much simpler. Instead of changing settings at random, you can treat the display setup as a short chain and find the point where the video signal stops reaching the screen.</p>
