I am selling a smart TV because I no longer need it. It was working without any problems until just before. It can be used simply by connecting it to the HDMI and USB ports of your TV. The remote control is not included, but you can use the Fire TV remote app on your smartphone, or if your TV supports "HDMI CEC (Consumer Electronics Control)" (such as Sony's "BRAVIA Link", Panasonic's "VIERA Link", Sharp's "AQUOS Familink", or Toshiba's "Regza Link"), you can use your TV's remote control. 【Technical Specifications】 Fire TV Stick 4K Size: 99 mm x 30 mm x 14 mm (excluding HDMI connector), 108 mm x 30 mm x 14 mm (including HDMI connector) Weight: 53.6g Storage: 8 GB Audio: Dolby Atmos, 7.1 surround sound support, 2ch stereo, up to 5.1ch HDMI audio passthrough Voice recognition: Supported by the free Fire TV remote app (available on Fire OS, Android OS, and iOS) Input/Output Ports: HDMI output, Micro USB (for power) Compatible TVs: (1) 4K TVs with HDMI ports, supporting 24/25/30/50/60Hz and HDCP 2.2, such as Sony, Sharp, Panasonic, Toshiba, Mitsubishi, LG, Samsung, etc. (2) HD TVs with HDMI ports, supporting 60/50Hz, 1080p or 720p, such as Sony, Sharp, Panasonic, Toshiba, Mitsubishi, LG, Samsung, etc. For more details, please check the official website (https://amzn.asia/d/iIR6oMf).
