Common Causes of HDMI No Signal Errors (DallasFixTech Insight)
- Faulty or Incorrect HDMI Cable: The simplest and most common cause. A damaged cable, a cable that's too long, or one that doesn't support the required bandwidth (e.g., trying to run 4K over an older HDMI 1.4 cable).
- Damaged HDMI Port: Bent pins, debris, or corrosion inside the HDMI port on either your device (PC/console) or the display.
- Incorrect Input Selection: The TV/monitor might be set to the wrong HDMI input (e.g., HDMI 1 when your device is plugged into HDMI 2).
- Resolution Mismatch: Your device might be trying to output a resolution or refresh rate that your display doesn't support.
- Outdated Firmware/Drivers: Old graphics drivers on a PC, or outdated firmware on a console or TV, can cause HDMI handshake issues.
- Power Issues: Insufficient power to the source device or display can prevent signal output.
- HDCP (High-bandwidth Digital Content Protection) Issues: Problems with content protection can prevent a signal from being displayed.
