- The device should be easily accessible to a power outlet.
Connections:
- HDMI: Connects to Blu-ray players, HD receivers, game consoles, etc. Supports HDMI Deep Color for clearer pictures (can be turned off if the device doesn't support it). Requires certified HDMI cables.
- USB: Connects to USB storage devices. Some USB hubs may not work; direct connection to the TV's USB port is recommended. Optimal connection requires USB devices/cables with specific bezel dimensions.
- IR Blaster: Controls external devices like set-top boxes, Blu-ray/DVD players, soundbars, and game consoles. Requires connection to the TV's IR Blaster port and universal control settings.

- Remote RS-232C Setup: Allows external control of the TV via a computer or A/V control system. Requires a USB to Serial (RS-232C) converter (PL2303 chip-based recommended) or an RS-232C (DE9, D-Sub 9pin female-to-female) cable, depending on the TV model. Set ID can be adjusted from 1-99 (0 for controlling all connected sets).
