Turning on your computer only to find that your monitor has “no input signal.” Can be frustrating. Lucky your monitor is still working, otherwise, you wouldn’t be able to see this message in the first place. So don’t panic just yet. Most of the time this is a faulty connection or worst-case scenario your video card is not working properly. Through this article we will take you through the steps to help you troubleshoot a few ways to uncover the issue to see if we can solve it.
Step 1: Check hardware for connection issues
The most common problem with no signal issue is that there isn’t a solid connection. First, check to see if your HDMI / VGA cable has is properly plugged in. Remove from the port and reinsert to make sure.
Check the cable that you are using to see if there is any damage to it. also, check the connections. If you are using a VGA or DVI cable make sure the is no bent pins on the cable or the in your PC. We want to make sure that the cable is still intact and there isnt any noticeable issues with the connections.
If the cable still seems to be intact and the connections are all in working order try using a different cable entirely. Try to use the same type of cable DVI, HDMI or VGA to see if the cable was the issue.
Alternatively if you are using a HDMI cable you can try plugging it in to another monitor. if nothing is available most TV’s have a HDMI port. Try it on your TV to see.
Step 2: Is your computer just in Sleep mode.
By this point, I think you would have bashed your keyboard out of frustration anyway. But it doesn’t hurt to double-check to see if your computer is in sleep mode.
To do this all you have to do is press the any key. Yes, the any key. Press enter, bash ghdehai, or simply hit any button to see if your computer wakes up after a few seconds. If it does then you have solved your problem.
Option 3: Restart your Computer
Have you tried to turn it on and off again? Sometimes all your computer needs are to simply restart.
Different steps to try
- Turn off your computer and monitor and unplug the cables.
- After a few minutes reconnect the cables and turn your computer back on.
Step 4: Select Moniter Source:
Most monitors might have a source button, to switch between VGA, DVI, or HDMI. Something like you would see on a TV when selecting between HDMI ports for your PlayStation and cable. If you by mistake selected DVI when your computer is using an HDMI port then your screen will have the dreaded “no input signal.” Double-check which type of source that you are using then make sure this is the same source that is selected on your monitor.
Step 5: Make sure drivers are up to date.
Now if your monitor is still not working you might have to update your video drivers. You will need a separate monitor and a different connection type. For example, if you are using VGA then trying plugging in an HDMI or DVI cable. If you don’t have a monitor try using a TV if you have an HDMI connection. Plug everything and proceed to update your drivers if you are able to see the screen.
