Usage Features
- Setup: Instructions for attaching/detaching the stand, tidying cables, and mounting the TV on a table or wall. Wall mounting requires VESA standard screws and brackets (100 x 100, M4 screws, 4 screws, LSW130B bracket for LN45** models).
- Connections: Detailed guides for connecting various external devices:
- Antenna: Connects to a wall antenna socket with an RF cable (75 Ω). A signal splitter can be used for multiple TVs, and a signal amplifier may be needed for poor image quality.
- Satellite Dish: Connects to a satellite dish with a satellite RF cable (75 Ω).
- Adapter: Connects the antenna cable to the TV, the DC adapter plug to the TV's power input, and the power cord to the DC adapter before plugging into a wall outlet.
- HDMI: Transmits digital video and audio. Recommends using the latest High Speed HDMI™ Cable with CEC function for optimal image quality (up to 1080p and higher).
- DVI to HDMI: Transmits digital video from a PC to the TV. An audio cable is required for audio transmission.
- MHL (Mobile High-definition Link): Transmits digital audiovisual signals from MHL-enabled mobile phones to the TV using an MHL passive cable. Some applications can be operated via the remote control.
- RGB (PC): Transmits video signals from a PC to the TV. An audio cable is needed for audio. Adjustments to PC output resolution, refresh rate, brightness, and contrast may be necessary to clear noise.
- Component: Transmits analog video and audio signals. Incorrect cable installation may result in black and white or distorted colors.
- Composite: Transmits analog video and audio signals.
- Euro Scart: Transmits video and audio signals. Any Euro scart cable used must be signal shielded.
- USB: Connects USB storage devices (flash memory, external hard drives, card readers) to access multimedia files. USB cables/devices should have bezels less than 10 mm thick and 18 mm wide.
- CI Module: For viewing encrypted (pay) digital TV services. Ensure correct insertion to avoid damage.
- Headphone: Transmits headphone signals. AUDIO menu items are disabled when headphones are connected.
