    Sometimes, the fault lies with the HDMI cable, OS issue, driver, etc. Therefore, in this article, we will talk more about different scenarios in which such a problem occurs and how to fix them.
    When connecting a laptop or PC to a TV or monitor, an “HDMI no signal” message often appears, showing the display input can’t detect an incoming signal.

    No HDMI Signal! Possible Reasons for HDMI not connecting:

    1. Faulty or unsupported HDMI cables, or slow data speed, often cause no signal errors.
    2. Outdated device drivers are another common issue; different displays need specific drivers for connection.
    3. Drivers act as a bridge for device connections. Using incorrect resolution drivers (like Full HD on a 4K device) results in no output.
    4. Matching drivers and correct I/O connectors are essential. Adjusting the TV’s or monitor’s resolution may help.

    Knowing these issues, let’s explore solutions step by step.

    How to fix HDMI no Signal from your device Issue:

    • First and foremost, turn off the computer and place it near your TV.
    • Leave the mouse and keyboard connected to the computer to manage the configuration.
    • Refer to the TV or monitor manual to understand the type of supported cable to connect.
    • Check the type and speed of the HDMI cable; any mismatch between the two may cause the problem. The different types of HDMI cables available in the market are Standard HDMI:720p/1080p, High-Speed HDMI: Up to 4K, and Ultra-High-Speed HDMI: Up to 10K resolution.

    • It is recommended to connect the cable to the TV or monitor before turning on the computer because there is a situation where the system may fail to recognize the external display.
    • Look for a different output device to test cable and display ports on TV or laptop/PC for compatibility issues.
    • After turning on the computer, the screen looks stretched, or part of the screen is not visible; you need to adjust the screen resolution in Windows.
    • The last option would be to check the drivers on the display and laptop/PC for any possible issues, and we will talk in detail about how to do this later in this article.

    Verify Input Source:

    Ensure the correct input source is selected on modern monitors and TVs, which often support multiple sources. ‘Auto mode’ automatically detects and switches the source. Change settings using the On-Screen Display (OSD) button or remote control, selecting from HDMI 1, 2, or VGA, depending on your connection.

    Projection Setting:

    If you are specially connecting your working desktop or laptop computer to 2nd or extended screen (like a monitor or TV), you must check the projection settings.

    Windows OS has 4 options as below:

    • PC Screen Only
    • Duplicate
    • Extend
    • Secondary Screen Only​

    You need to ensure the correct option is selected to push the display to 2nd screen, which can consequently eliminate the HDMI no signal from your device error.

    Windows users can use 'Windows key + P' to get this option. Also, you can use the system tray options to get this option in Windows 11/10.

    Display Driver Setup in Windows 10/11

    When connecting a new device to a PC or laptop, Windows searches for and tries to install necessary drivers. In cases where automatic updates fail, manual driver updates through display settings are needed.

    • Right-click on desktop -> Select Properties or Personalize option
    • Now select Display Settings from the list of preferences
    • An icon with numbers will be displayed on it for attached monitors to connected devices. If there is only one device, then there will be no option to toggle between display screens

    • In the same icon with numbers displaying screen, select the display monitor and select either extend your desktop or mirror your desktop option.
    • The screen blinks for a second or two, connecting to the selected display.

    In instances where single multiple screens connect to the same PC or laptop, graphics card-dependent displayed settings may require changes from the Windows 10 control panel.

    Install or Update Display Drivers using Device Manager.

    • To update the display drivers, go to Start -> Type device manager -> enter
    • In the next screen, select display adapters -> Select “Intel UHD Graphics 620” or any other options that you see under “display adapters.”
    • Right-click on “Intel UHD Graphics 620″-> update drivers -> two options will pop up on the screen: Manual update option as Browser for drivers on the computer and automatic update option would be listed as “Search automatically for updated drivers software.”

    • Select Search automatically for updated drivers software option first and let Windows search and install appropriate drivers.
    Auto Update
    • If automatic driver updates fail, switch to manual updating: select “Browse for drivers on the computer,” find the driver file if available, and proceed to configure it.
    Manual Update
    • If the downloaded driver is not available, you can choose ‘let me pick from a list of available drivers on my computer,’ select an available driver, and click next to install.
    • If a Graphics card is configured on the laptop or PC, then a different version of the display driver update is required. The latest display drivers can be downloaded from respective vendor portals like NVIDIA or AMD driver download page.

    Check and Adjust Your Hardware Setup

    If “no HDMI signal” persists, try these steps:

    1. Power cycle the monitor and TV to fix temporary issues: turn off, unplug HDMI and power cables, wait, then replug.
    2. Check cables and ports for damage or dirt; replace if necessary.
    3. Test with a different monitor or TV to check your laptop/desktop output.
    4. Reseat the display card on desktops using dedicated cards if the issue continues.
