The JVC Professional VF-HP790G is a high-definition studio viewfinder engineered to provide camera operators and engineers with a superior, large-screen monitoring interface for the GY-HM790 and GY-HM890 series camcorders when docked in a studio configuration. Its defining feature is a large, high-resolution 8.4-inch LCD screen capable of displaying both HD and SD video signals with excellent clarity and color accuracy. Beyond simply showing the camera's output, this viewfinder integrates full camera menu control, allowing operators to navigate and adjust all camera settings—such as paint parameters, audio levels, recording setup, and system configurations—directly from the viewfinder's controls without needing to access the camera body itself. This centralized control is crucial for efficient operation in fast-paced studio, broadcast truck, or live production environments.

Designed for ergonomic integration into a studio sled or mounting arm, the VF-HP790G connects to the camera system via a multi-core cable that carries video, power, and bidirectional control data. It often features a hood to block ambient light and customizable overlays for safe area markers, focus peaking, and zebra patterns. By combining a large, detailed display with comprehensive camera control, this viewfinder transforms the operator's experience, providing the visual feedback and command interface necessary for precise shot composition, exposure adjustment, and overall camera management in a professional studio setting.
