Big-screen gaming that lives on your keychain.

Key Cast casts your phone to any HDMI display in seconds at 4K/60Hz, then folds down pocket-sized and clips to your keyring, popping open with a press. Built-in 2.4GHz chip for lower latency, higher poll rate, and more range, no pairing needed.

USB-C to HDMI. (HDMI cable not included.)
