Additional useful information
Identify Chromecast with Google TV 4K by GZRNL, then use this source-reviewed page to check its video, audio, network, power, remote, connection, reset, and exact accessory requirements before replacing parts.
GZRNL identifies the 4K version of Chromecast with Google TV. Google's specification page lists up to 4K HDR at 60 frames per second, Dolby Vision, HDR10, HDR10+, HLG, Dolby Atmos pass-through, dual-band 802.11ac Wi-Fi, Bluetooth, integrated HDMI 2.0, and USB-C power at 5 V DC and 1.5 A. Wired networking needs Google's separate Ethernet power adapter because the dongle has no RJ45 port. Plug it into a compatible HDMI input, connect the included wall supply, pair the two-AAA Chromecast Voice Remote, and complete Google Account and network setup. For 4K playback, Google also requires a 4K display, suitable HDMI path, 4K content, and adequate broadband. Low-power warnings call for the original-rated supply and cable, without an unsupported hub. If the screen is blank, check the selected input, HDCP chain, extension capability, and firmware before factory reset. Reset erases accounts, apps, and local settings. Do not apply this row to the similar Snow G454V HD device, which is limited to 1080p and does not list Dolby Vision. Google TV Streamer is a different set-top product with HDMI cable, Ethernet, 32 GB storage, Matter, and Thread.
- Networking: Dual-band 802.11ac Wi-Fi and Bluetooth
- Power: USB Type-C at 5 V DC and 1.5 A with included supply
- Ethernet: Available only through Google's separate Ethernet power adapter
- Remote: Chromecast Voice Remote uses Bluetooth and two AAA batteries
- Storage caveat: Limited internal app storage is not a user-removable media slot
- Variant caveat: GZRNL is 4K and must not be confused with 1080p HD model G454V
