Error Codes (102): Troubleshooting, Fixes & Prevention Tips explained below.

What Does HDMI Handshake Failure Mean❓

HDMI Handshake Failure occurs when connected devices fail to properly establish communication through the HDMI connection. The “handshake” is a process where the source device (like a Blu-ray player, game console, or computer) and the display (such as a TV or monitor) exchange information about supported video and audio formats. If this process fails, you may experience no picture, no sound, flickering, or error messages. This failure can be caused by incompatible devices, cable issues, or firmware problems.
