HDZero Quad Viewer

Four FPV feeds. One ultra-bright screen. Built for race day.

The HDZero Quad Viewer combines the functionality of four HDZero monitors into a single, rugged unit with a large 10.1-inch high-brightness display, making it ideal for race spotters, spectators, and race directors who need to track multiple pilots at once.

With support for HDZero digital and analog video, the Quad Viewer allows you to monitor up to four FPV feeds simultaneously in a quad-view layout or switch to a single full-screen feed for detailed viewing.

Designed for Outdoor Events

The Quad Viewer features a super-bright 1800+ nit screen, ensuring excellent visibility even in direct sunlight. Whether you’re standing trackside or managing an event tent, the display stays clear and readable all day long.

Smart Video Handling

Each channel automatically switches between HDZero digital and analog video based on signal strength for the selected race channel. This makes the Quad Viewer compatible with mixed pilot setups without manual intervention.

Ideal for Racing and Events

Spotters can track pilot position and relative progress in real time
Spectators get a clear view of multiple pilots simultaneously
Race directors benefit from a built-in monitoring screen and simplified HDMI output

The Quad Viewer also functions as a 4-to-1 HDMI multiplexer, combining all four FPV feeds into a single HDMI output in a quad-grid layout for external displays or streaming setups.

Note: HDMI output resolution is limited to 1280×720p. For higher-resolution per-channel output, the standard HDZero Event VRX remains the preferred solution.

Flexible Power Options

Power the Quad Viewer easily using:

XT60 input (2S-6S LiPo) - perfect for race-day battery swaps
DC barrel connector - for bench or fixed installations
USB-C - great for powering with a USB-C PD power bank

Finding power at the field is never a problem.
