[Solved] No HDMI Signal From Your Device Error
When you get the “No Signal” error on your HDMI devices, it means that your monitor or TV is unable to get any input from the currently selected source. But, worry not. There are five workarounds you can try. Work your way down the list and you will bring back signals for your HDMI device.
- Check the input source
- Check the cable connections and display settings
- Update your chipset drivers and graphics drivers
- Try a factory reset
- Check for hardware issues
Before we start troubleshooting, please restart your computer to flush the buffer. Also, make sure that your HDMI devices have a stable power supply. After that, proceed with the steps below.
In case you selected the wrong input source, we recommend checking the input source on your monitor or TV.
To do so, press the Input or Source button on your remote (or on the sides of your monitor or TV) to switch the input source to the HDMI port. If you have more than one HDMI port, ensure to select the right HDMI port. (If you can’t find the Input or Source button, check the user manual, or look up your model on the internet to determine where the button locates.)
If the right input source is currently selected, then check the connections and display settings as in Tip #2.
Now, please check that the HMDI cable is plugged into the correct port on both your computer and the monitor or TV. If so, check if the correct projection is set on your computer. Here’s how to do it:
- On your keyboard, press the Windows logo key and P together, and then select the correct projection which you are trying to obtain. If you’re using an external monitor, you can choose Duplicate or Extend.
Check if your monitor gets an input signal. If not, move on to the next tip.
When you encounter the “No Signal” error, one of the first things you should do is to update your chipset drivers and graphics card driver since an up-to-date graphics driver always ensures the best gaming performance and fewer bugs.
To update your chipset drivers, please refer to this post.
To update your display card driver, here’s what you can do (please note that the following screenshots are taken on Windows 11, but the instructions work on Windows 10 as well):
- On your keyboard, press the Windows key and X at the same time, select Device Manager.
- Double-click to expand the category Display adapters. Then right-click your graphic card driver and click Update driver (the name of the device can be different on your computer).
- Then click Search automatically for updated driver software.
- Wait for Windows to find the latest driver available for you.
- When the driver update is done, restart your computer for the change to take effect.
- Then check and see if the problem is fixed.
If Windows says that it’s already found the latest driver for you, so no newer drivers are found, then you should consider updating your graphics driver in a different way with the help of Driver Techie.
Its ever-growing driver database allows you to always have access to the latest device drivers that you need. More importantly, Driver Techie simplifies the driver update process, so all it takes is just 3 clicks (for Pro users), and all your drivers are updated.
To use Driver Techie to find you the latest drivers:
- Download and install Driver Techie, then launch it.
- Click Scan Now.
- After the scan, select all the drivers you need to update and click Update All. Then all your drivers will be updated automatically without you having to do anything else.
Please note that Update All is available for Pro subscribers only, otherwise, you can only manually update the driver one at a time. To see how to manually update the drivers one by one, please check this post.
If you’re a Pro user of Driver Techie, and need our technical support to help with the HDMI no signal problem, please feel free to contact <firstname.lastname@example.org>.
If updating the driver still fails to resolve the HDMI no signal problem, then you can consider doing a factory reset for your monitor or TV.
To perform a factory reset for your monitor or TV, you will have to open the Display Settings menu. (There should be a Menu button on the side of your monitor, or on the remote of your TV. Please look it up in the User Guide.) Once you enter the setting page, look for the reset option and select it. Then, wait for the reset to complete.
Please note that the screenshot below is only for your reference.
Once done, restart your computer and your monitor/TV. Then, check if the problem persists. If so, you should consider the possibility of hardware issues as mentioned in Tip #5.
If none of the solutions above fixes the HDMI no signal issue for you, then you need to check if either the input device or the output device is having a hardware issue. However, there are more than 3 items you need to check, such as your graphics card, HDMI cable, HDMI ports, your monitor, and your TV. Since it requires advanced technical skills to complete, we recommend you seek help from a repair store or the manufacturers of your devices.
At last, we hope that you find a final solution in this post and that your HDMI no signal problem will soon come to an end. If you have any ideas to share with us, please feel free to leave a comment down below.
