First things first, the major yet most simple issue with the monitor showing no signal error is none other than loose cables or incorrect plug-ins. Now there can be a chance that either the cable, which you have plugged in, is not appropriately connected to the monitor to input signals, or the HDMI connection isn’t supporting the access.

Having considered that, before you get to any possible fix, it is important to recognize the problem first. And for that, you just need to trace the cable that connects your monitor with your PC or system unit. If the connection is strong enough and you don’t find the cable attached loosely connected to the monitor, then there is some other reason behind the ‘no signal’ error.

For instance, it can possibly be a faulty display cable. In addition to that, the display cable can be broken or worn out as well. So in that case, all you need to do is replace it with a new one.

Now:

What if you don’t find any of these issues with your monitor or PC? That’s where you need to check some other peripherals. With that being said, let’s have a look at all the other possibilities that might cause your monitor to display the ‘no signal’ error. Here we go:

Check the Power Source

No signal on monitor new PC? Make sure to check the power source then. This is for the reason that at times, the display cable is plugged-in perfectly, but your PC isn’t connected to the power source, which prevents the monitor to turn on, in the first place.

Check the Monitor Input Source

Secondly, another major cause of seeing a ‘no signal’ error on the monitor could be that your monitor supports a different kind of input source, and you’re plugging in the wrong cable. For instance, if your monitor is supporting a VGA connection, then you’d be needing a VGA cable instead of an HDMI – and vice versa.

Having said that, there are multiple input sources available, as in VGA, HDMI, and several other DVI inputs. In all cases, you gotta be very cautious while buying the input data cable, in order to avoid any future inconvenience.

Check Monitor’s Resolution

Now that you have checked your computer’s power source and the cable connections as well; but the issue still persists, then you better head towards your monitor’s resolution settings.

Having said that, the first thing, which you need to ensure, is that your monitor is capable of displaying the resolution that your PC’s graphics card is generating. With that, you’d only be able to have a video output. Otherwise, it would be sending improper or no video input on monitor – resulting in blank screens.

Now to resolve this problem, you have to change your monitor’s resolution settings, by either turning off or rebooting your PC into Safe Mode. This will help you fix Windows 10 monitor no signal issue as well.

In addition to that, your Windows PC will start working on a much lower display resolution in Safe Mode, through which you can eventually switch to a compatible resolution setting that your monitor supports.

Lastly, if you are unaware of your monitor’s resolution settings, then you can read the instructions mentioned in the user manual. Or else, you can access the help center at the manufacturer’s website in order to get it resolved.

Fix Your Graphics Card: Hardware Update

Last but not least, if you have tried all of the above-mentioned particulars, and still face the no signal issue, then there is absolutely something wrong with your computer’s graphics hardware.

That said, you may have a faulty graphics driver or an incompatible one, which does not generate resolution as much as your monitor’s capacity. So in either of the cases, you simply need to replace it with a new one.

Now that can be done in two ways: one is by updating your graphics card manually, and the other is by updating your drivers manually.
