You can quickly fix this no signal problem with the following measures. The following will give you the information of why there is no HDMI signal from your device.
Make sure you have started your device with the power button
Human error is possible in such cases. Make sure you have pressed the power button of your input device before making any changes to the configuration. Man can forget to on the device. Sometimes, they press the power button two times. So, the device gets both commands. It starts but again shut down because of the power button. Another reason can be the standby mode on your devices. Again, press the power button to ensure that it is not in standby mode. If this is the problem, restart your device. It will solve the issue and your device will get the signals.
Check and ensure physical connections
If your device is properly on, you should move on to this step. Check your physical port connection. Sometimes, it becomes unplugged or not properly plugged into the port. It is called a weak physical connection. Your device is unable to get signals because of this weak physical connection. Plug your cable properly. You should not take any measures regarding the software configuration before ensuring the proper physical connection and the device. Wiggle the port with your hand push. Your HDMI devices may have many connections with them. You should disconnect all the connections first to solve the signal problem.
You just have to turn off the connected devices with your HDMI system. After the complete shutdown of all devices. You should again plug in the power cables of the devices and connect them with HDMI connection ports. Your problem will be solved by this quick fix available for the hardware type of problem. Also, check that your HDMI port is working properly. It can also become loose and cause failure in the connection.
Change your input source
You should check your input source, this may help you to solve why there is no HDMI signal from your device. If the input source is not working, try a different source to get the signals on your monitor. Making software changes is of no use when there is a problem with the physical devices. You might plug in the input source with the wrong port. So, check that you have correctly plugged in your cable to the right port. If it is not the right port, try the other input source port. Pick up the right input for your display to get the HDMI signals to your monitor. You can also do software configurations to change the input channel
Use an HDMI cable of a shorter length
HDMI ports come in different lengths. It depends on the type of port you have on your device. You must have to ensure that the device port length is enough to handle the HDMI cable plugged into it. The maximum length of the HDMI cables is fifteen meters. We can use only short-length cables to display high-screen resolutions on some devices. There are different criteria for each type of device. These criteria are as follows:
You should the resolution of your monitor. If you have a 4K resolution screen, your HDMI cable port length should not be less than three meters. As we know that long distances make the signals weak. The shorter distance is best for the fast signal speed. The signals cover shorter distances and reach quickly to destinations.
Make changes to the display resolution
Ensure that your screen resolution is compatible with your HDMI resolution. When you try to use different resolutions for the same media content, the system does not quickly adapt to these changes. Your device will show weak signals if you try to play the 4k content with a cable of length more than 5 meters. You can also face weak signals or no signals at all. You have to make your screen resolution compatible with your PC’s screen resolution.
The best way to fix the resolution problem is to manually change the setting to automatic adjustment of the screen resolution. The screen will adapt itself according to the resolution of the monitor display settings are set to automatic.
Ensure your firmware is not out of date
Your device should be the latest. If your input and output devices are not compatible with each other. There are different types of factors that affect signal strength. Any signal that comes out and goes into the device depends on various factors. One of the factors is the handshake problem between the old and new devices. This handshake will not happen successfully if the devices are not compatible with each other. If you have the new display device and the device that is used to output the result is older, your handshake phenomenon becomes fails and your device will get weak signals or no signals coming from the source towards the destination.
Update the firmware of the old device to resolve this issue of compatibility. There are different methods to update the firmware of the hardware device. You can try one of the following methods to update your older version of the device firmware:
- You can use the internet connection on your device by using the USB port.
- You can play a disc to resolve the firmware updating issue.
- You can create an RS232-C-type connection to your system.
- You can use the user manual of the device to follow the instructions to update the device firmware.
- You can contact the developer of the device to update your device firmware.
Change the connection type
If you are still having the issue, your device resolution screen display is correctly working. You need to take other measures to solve this signal issue. Change the connection type of your device. You must have to connect your device using different inputs. The input can be using a VGA port. Now, check whether your device is getting the signals or not.
The user must know that both the ports are different in their functionality but you can connect the input cable with the visual graphics array port to check whether the problem is in your connection input or not. You will the insight into your problem by connecting the HDMI wire to the VGA port. To check the working on the HDMI port, you can take the following measures. Make a dedicated connection between the VGA port and your computer using a VGA cable. Change the input from the TV menu. Find the VGA option and choose the VGA option from the given windows. Check whether it works or not. If it is working then there is a problem with your device’s HDMI port.
Make changes in the sequence of boot
The sequence of devices matters. It affects the result. You should change the order in which you are starting your devices. All the connected devices are powered on with a sequence. You should change this sequence to resolve your signal issue. You can reverse the boot sequence of all the connected devices with the input. You should do the exact opposite of what you were doing before. You should disconnect the HDMI ports before shutting down the devices.
