Fix: No Signal on the Monitor but the PC is Working
Choose the correct display resolution
- The no signal on monitor error may suddenly show up whenever you power on your Windows PC.
- This issue mostly occurs due to hardware issues such as a damaged HDMI cable as well as an outdated graphics card driver.
- Updating your display drivers and choosing the correct input source may prove helpful in this scenario.
In an unfortunate circumstance, you might have noticed a no signal error on the monitor as soon as you turn on your Windows PC. When this happens, no image is displayed on the screen, and as a result, your monitor is rendered useless.
If you are facing the same issue on your system, this guide has got you covered.
Why is there no signal on the Monitor but the PC is working?
There can be several reasons why your monitor displays No input signal message, and no image appears on the screen. Here are a few prominent ones:
- Loose or faulty cables – A loose connection between the PC and Monitor and a broken cable often causes this error.
- Incorrect display settings – The no signal on monitor error also indicates that the display settings are not properly configured.
- Faulty monitor – You may also witness the no signal on the monitor message if there is some fault in the output device itself.
- Outdated drivers – If the display drivers become corrupt or outdated, you are likely to face display errors like the one at hand.
- Hardware issue – Some physical damage to the hardware, particularly the monitor, CPU, and cables, can also trigger the error.
Regardless of the reasons why the no signal error on the monitor error shows up, it is quite easy to troubleshoot.
How do I fix the no signal on the monitor error?
Before moving on to move advanced fixes, you should perform the following preliminary checks.
- Ensure that there is no connection issue between the CPU and monitor by checking that the video cable is firmly connected.
- Use a different video cable to connect the monitor and PC to rule out the damaged HDMI cable possibility.
- Make sure that the graphic card is firmly inserted into its slot located on the motherboard.
- Connect a spare monitor to the PC to check for any damage to the monitor.
In case these tricks do not help alleviate the problem, try the below fixes.
1. Select the correct input source
- Power on your computer and then your monitor.
- Press the Menu button on the side of the monitor to view the menu options.
- Keep pressing the Menu button to access the Input Source and then select the correct choice. For instance, if your monitor is connected to the VGA port, you should select VGA as the input source.
