Configure Your TV for 4K120/8K60 Video Passthrough

Most modern TVs automatically detect and enable 4K120/8K60 passthrough when paired with compatible devices. However, some models require manual configuration.

⚠️ Change these settings only if a 4K120/8K60-capable device (e.g. console or PC) is connected to Shockwafe Wireless, but your TV is not displaying content at the expected resolution or refresh rate.

💡 Steps vary by model and brand—refer to your TV’s support documentation.

Before You Start:

Ensure the TV’s eARC port supports 4K120 refresh rate.
Ensure your console or PC is configured to output 4K120/8K60.
Use a certified HDMI 2.1 cable shorter than 10 feet for maximum stability.
