High-quality 4K HDMI cable from Type-C, 3m long, allows connection of smartphones and tablets to a large-screen TV. - Cable Type: Type-C to HDMI - Length: 3m - Supported Resolution: 4K - Application: Connect smartphones/tablets to large-screen TVs - Included: Instruction manual I opened it, but it wasn't compatible with my device, so I gave up after trying to connect it once. The box is a little torn, but the main unit is like new. Thank you for looking.
