The CJ TECH HDMI Cable operates passively, transmitting digital audio and video signals between compatible devices. Once connected, it requires no additional configuration. The quality of the signal (e.g., 4K resolution, 3D content) will depend on the capabilities of your source and display devices.
- Resolución 4K: To experience 4K resolution, ensure both your source device (e.g., 4K Blu-ray player, 4K streaming device) and your display device (e.g., 4K TV) support 4K output and input, respectively.
- Contido 3D: Para 3D viewing, your source device must output 3D content, and your display device must be 3D-compatible.
- Formatos de audio: The cable supports various audio formats, including Dolby True HD, DTS-HD Master Audio, and standard stereo audio, depending on your connected devices.
5. Coidados e mantemento

- Manter limpo: If connectors become dusty, gently wipe them with a dry, lint-free cloth. Do not use liquid cleaners.
