When you encounter issues with HDMI connections after changing the operating system, such as from Windows Vista to Windows 7 Professional, there are a few troubleshooting steps you can take to address the problem:

Troubleshooting Steps:​

1. Check Display Settings:
   • Right-click on the desktop and select "Screen Resolution" or "Display Settings."
   • Ensure that the correct display is set as the primary monitor and that the resolution is appropriate.
   []Update Graphics Drivers:
   • Outdated or incorrect graphics drivers can often cause display issues.
   • Visit the manufacturer's website for your PC or graphics card to download the latest drivers for Windows 7 Professional.
   []Check HDMI Cable and Ports:
   • Ensure the HDMI cable is securely connected to both the PC and the TV/monitor.
   • Try using a different HDMI cable to rule out any issues with the existing cable.
   • Test the HDMI ports on both the PC and the TV/monitor to verify they are functioning correctly.
   []Configure HDMI as Default Output:
   • Right-click the volume icon in the system tray and select "Playback devices."
   • Set the HDMI device as the default audio output if required.
   []Restart Windows Audio Service:
   • Press Windows key + R, type services.msc, and press Enter.
   • Locate "Windows Audio" in the list, right-click it, and select "Restart."
   []Try Different HDMI Port:
   • If available, try connecting the HDMI cable to a different HDMI port on your PC.
   • Some PCs have multiple HDMI ports, so testing different ports can help identify if a specific port is causing the issue.
   []Test with Another Device:
   • Connect the PC to another TV or monitor to see if the issue persists.
   • This helps determine if the problem lies with the PC or the original TV/monitor.
2. Check TV/External Monitor Settings:
   • Ensure the TV or external monitor is set to the correct HDMI input channel.
   • Check the TV/monitor settings to verify that HDMI input is enabled and functioning.

     Additional Considerations:​

     • Compatibility: Ensure the HDMI port on the PC is compatible with the TV/monitor.
     • Firmware Updates: Check for any firmware updates for the TV/monitor.
     • Reset TV/Monitor: Power cycle the TV/monitor by unplugging it for a few minutes and then plugging it back in.
     By following these steps, you can troubleshoot and potentially resolve the HDMI connection issue between your Windows 7 Professional PC and the TV/monitor.
