S SK_tech Member Jul 11, 2025 #2 HDCP error usually shows up when your device (like a laptop or streaming box) and your TV or monitor aren’t playing nice with copy protection stuff. Try this: Unplug and replug the HDMI cable. Use a different HDMI port or cable. Restart both devices. Make sure your display supports HDCP. Avoid HDMI splitters — they often cause issues. If it keeps happening, switching to a different screen or using a certified cable usually helps.
