Connections

Connect external devices such as Blu-ray players, HD receivers, PCs, and gaming consoles to the TV using appropriate cables (e.g., HDMI, USB). Switch input modes to select the desired external device.

HDMI: Use certified HDMI cables. Ensure both the TV and external device are off and unplugged before connecting. For optimal clarity, ensure the connected device supports HDMI Deep Color; if issues arise, disable this setting in the TV's menu.
