Whether you’re trying toset up multiple monitorsor use anexternal display for your laptop, the “No HDMI signal” error might pop up. This message could indicateissues witheither of your devices(source or destination).
You could also experience it due to incorrect source/projection settings, outdated drivers/firmware, or damaged components. But before diving into the related fixes, we recommend checking the loose connections first andtry replugging the HDMI cable.
Verify Input Source
Adjusting the correct input source is an important thing to consider. If you’ve plugged in your HDMI cable to one port and set the input source to another, your monitor won’t display anything or will likely throw the “No HDMI Signal” error. Here’s a quick workaround to this problem:
Change Projection Setting
If you get the “No HDMI signal” error after connecting your laptop to an external monitor, there may be an issue with the projection setting.
There are four different options available – PC Screen Only, Duplicate, Extend, and Secondary Screen Only. While the latter three options will cast your laptop content, the first one will not send an HDMI signal to the external display. Here’s a simple guide to changing the projection setting to fix this problem:
Power Cycle Your Monitor
Sometimes, the bugs and glitches within your monitor could interfere with the HDMI signals. In such a scenario, performing a power cycle (turning the monitor on and off) will reset the configuration parameters, which might fix the error.
Here’s how you can do this the right way:
Try Using Another HDMI Port or Cable
Damaged ports and cables could be the other reason you’re facing a signal problem on your device. To identify whetherHDMI is working or not,check for bent/broken ports and cables.
You may even plug in another HDMI device on the port to identify if it has some sort of issue. Likewise, you can try a spare cable to find out if the former one was faulty. If you encounter any problems with the HDMI cable, kindly replace it with a new one.
Well, you may even get aSyncwire HDMI cablefor better durability and flawless transmission. Thanks to its metal construction, the cable won’t get damaged even after being bent over 3000 times.
Check Problem in Another Monitor
Another method to solve the “No HDMI signal” is to check the issue on another working monitor. This is to identify whether any components of your display device are damaged.
If you do not get any signal, know that there are problems with your PC, cables, and ports. However, if the desired content is displayed on the screen, it’s a clear sign to troubleshoot your monitor or youmight even need to replace it!
Update Your Display & Monitor Adapters
The display adapters are responsible for sending display images to the monitor or related devices. Any issues with its drivers can directly affect the signals despite thetype of monitor connectionyou’re using.
Likewise, only one display in a multi-monitor setup may show the “No HDMI signal” error. This is probably due to an outdated or corrupted monitor driver.
If you’re able to access the source device, we advisechecking the issue insafe modefirst. If the problem prevails, follow the below steps tocheck and update the device drivers:
Reseat Memory Modules
If the memory module hasn’t been installed properly, your device simply won’t boot. So, there’s a maximum chance that your output device won’t display anything or throw a signal error.
In this case, we recommend reseating the RAM sticks and cleaning the slots well. This ensures no debris or dust is stuck while the memory module is seated. Below is a simple guide that should help you clean and reseat the RAM:
Update Monitor Firmware
A corrupted monitor firmware often leads to unexpected display errors. Even when everything looks fine, the “No HDMI signal” might pop up on your output device. Regarding the same, here are the necessary steps you need to adopt forupdating the monitor firmware:
Factory Reset Your Display
The final option is to perform a factory reset to restore the monitor to its original configuration. This will fix any bugs or glitches that might have interrupted the HDMI signal. For demonstration, we have used the MSI Optix G241V E2 model. But the steps should be similar on other monitors too:
