Suddenly getting a notification on your PC monitor screen that your HDMI signal has been lost can be very infuriating, especially when you are trying to complete a work project while projecting your work on a large screen such as a electronic device screen and you get a “no HDMI signal” notification. Confusion might set in because you were not expecting to see notifications about your PC’s HDMI signal at that time. This article is a guide on the steps to take when you get a no PC HDMI signal on your PC VDU screen.
PC HDMI has no signal
Your Windows/iOS PC might suddenly show the “no HDMI signal” notification because of several reasons. Some of these reasons for your Windows/iOS PC suddenly sending you a “no HDMI signal” notification are: your Windows/iOS PC is in sleep or hibernation mode and because it is in sleep or hibernation mode, it fails to send signals to your Windows/iOS PC’s screen. Also, your Windows/iOS PC accessory wiring and ports might be the problem. It may also be a problem of wrong settings on your Windows/iOS PC can cause it to send you a “no HDMI signal” notification. The reasons for your seeing a “no HDMI signal” notification while working on your Windows/iOS PC screen would be discussed here.
Faulty Windows/iOS PC accessory ports wire connections
Your Windows/iOS PC HDMI connection is made of wires and ports. For your Windows/iOS PC HDMI to be able to send signals to your monitor screen, all the ports and wires in the HDMI-to-monitor connection setup must be physically okay. If the ports and wires that make up your Windows/iOS PC’s HDMI setup are not physically okay, you would see a “no HDMI Signal” on your Windows/iOS PC screen.
Glitches on your Windows/iOS PC
A “no HDMI signal” might pop up on your Windows/iOS PC screen because of a glitch. A possible cause of your Windows/iOS PC glitch could be your connecting HDMI cables with your Windows/iOS PC while your Windows/iOS PC is still on and running. This glitch is temporary 90% of the time and can be eliminated. The temporary glitch on your Windows/iOS PC might obstruct HDMI signal flow to your Windows/iOs PC monitor which would lead to your Windows/iOS PC sending you a “no HDMI signal” notification.
Wrong Monitor inputs
Another possible cause of your Windows/iOS PC sending you a “no HDMI signal” notification is a wrong input on your Windows/iOS PC. A wrong input source on your Windows/iOS PC could lead to the monitor’s failure to send graphics output from your Windows/iOS PC. Modern Windows/iOS have input sources like DVI, VGA, and HDMI. If you were supposed to connect with an HDMI input source and you instead connected with a VGA input source, your Windows/iOS PC would fail to send out graphics output, and you would get a “no HDMI signal” notification.
Low Monitor Resolution
Your Windows/iOS PC display resolution might not be up to what is required to get HDMI signals. If your Windows/iOS PC’s graphics card has a far higher resolution than what your Windows/iOS PC monitor can display, you would get a “no HDMI signal” notification on your screen. The reason for this is that your Windows/iOS PC’s graphics card is the main component responsible for producing graphics from your Windows/iOS PC and this graphics card usually has its default resolution. If your Windows/iOS PC monitor does not have the same resolution as your Windows/iOS PC graphics card, it would not be able to transmit your Windows/iOS graphics output to the external screen as HDMI signals.
Outdated Windows/iOS PC graphics card.
Another reason for a “no HDMI signal” notification popping up on your screen could be an outdated graphics card. The resolution of the graphics card on your Windows/iOS PC might not meet the required resolution for your Monitor to transmit the HDMI signal, and because of that, you would see a “no HDMI signal” notification pop up on your screen.
Malfunctioning Hardware
The “no HDMI signal” notification on your screen may be due to a malfunction of your Windows/iOS PC. Common malfunctioning Hardware that causes “no HDMI signal” notifications are graphic cards and random access memory (RAM). If your graphic cards are malfunctioning, there would be no graphics output transmission in your Windows/iOS PC. Also, if your random access memory sticks are malfunctioning, computer operations on your Windows/iOS PC would be slowed down or stopped altogether, and you would get a “no HDMI signal” notification on your screen.
Software issues
The reason why you got a “no HDMI signal” notification may be because of a software issue. Software issues like a malicious software infection of your Windows/iOS PC can cause your Windows/iOS PC to malfunction. This malfunction can include a failure of your Windows/iOS PC to send out graphical output. The failure of your Windows/iOS computer to send out graphical output would lead to you getting a “no HDMI signal” notification on your screen.
Software bugs
Continuous update of your operating system and other software and drivers is the best way to make sure that your Windows/iOS PC works optimally. But, the drawback of continuous of your Windows/iOS PC software and drivers is the introduction of bugs that can meddle with the operations of your Windows/iOS PC. If your Windows/iOS system’s operations are not smooth, your output would be affected and it would lead to you getting a “no HDMI signal” notification on your screen.
Solutions to ” no HDMI signal” problems
Getting a “no HDMI signal” notification is not unsolvable, as there are many solutions to a graphical output blockage problem or an HDMI transmission problem to your electronic device screen or your game console, or anything else you are transmitting your Windows/iOS PC monitor. Here are possible fixes for the “no HDMI signal” notification.
- Check your HDMI wires and your HDMI port
As soon as you see the “no HDMI signal” notification on your screen, the first thing to do is to check the HDMI cables and port. Run your finger from your electronic device’s HDMI port all through to your Windows/iOS PC’s HDMI port to see if the HDMI wires were properly inserted into both your electronic device and your Windows/iOS PC’s HDMI ports.
If after running your finger through from your electronic device’s HDMI port to your Windows/PC’s HDMI port, you find no fault with the HDMI connection, you need to check the ports themselves, to see if they are already bent. If the HDMI ports are already bent, call an expert technician to come to fix the HDMI ports for you.
- Try using a different HDMI wire
If after checking both your HDMI wires and ports, you see that they are intact, your HDMI wires might have internal cuts. If this is the case, try connecting a new HDMI wire to your HDMI ports, and see if the “no HDMI signal” problem would be solved.

If after running your finger through your HDMI wires and ports and there is no problem, and also changing your HDMI wires and there is still no problem, consider changing the source of graphics input from HDMI to DVA or from HDMI to VGA and see if you successfully transmit. If you don’t, the problem is either with your Windows/iOS PC monitor or other hardware like the graphics card.
- Check your Windows/iOS PC’s monitor and graphics card resolution
Your graphical output hardware includes your graphics card and your monitor. For your Windows/iOS graphical output to be frictionless, the two pieces of hardware would need to be of the same resolution. Check your Windows/iOS PC monitor and graphics card to see if they are of the same resolution and if they are not, update the resolutions.
