4K HDR Display ON/OFF Controller

Ideal Use Cases

The Kramer FC-18 is designed for HDMI systems in which a display or projector should turn on when a source signal becomes available and turn off when that signal disappears. It monitors the HDMI input and automatically sends the appropriate power command when it detects either the onset or loss of the signal. This makes it suitable for installations that need display power to follow normal source operation without requiring a separate manual action each time.

The controller also supports situations where direct operator control is preferred. A connected display device can be controlled through the FC-18 front-panel buttons, over Ethernet, or with contact closure switches. These options allow the same controller to support automatic operation, local control, and externally triggered control.

Why Choose This Model

The FC-18 combines display power control with support for high-quality HDMI signals. It accepts and outputs 4K@60Hz video with 4:4:4 color sampling and HDR. Listed HDR compatibility includes HDR10 and Dolby Vision. This combination allows the controller to manage display operation while remaining in the path of a 4K HDR HDMI system.

Its automatic behavior is based on actual input-signal status. When a signal begins, the unit sends an ON command to the connected display or projector. When the signal is lost, it sends an OFF command. This direct relationship between source activity and display control provides a clear, repeatable operating sequence.

Installation and Integration

The FC-18 accepts an HDMI signal, processes it, and provides an HDMI output for connection to a display or projector. Within that signal path, the unit reclocks and equalizes the HDMI signal. The product data does not specify cable requirements, mounting arrangements, power details, or physical dimensions, so those installation parameters should be confirmed separately when planning the complete system.

Control integration can be matched to the needs of the installation. Front-panel buttons provide control at the unit itself. Ethernet enables control through a network connection, while contact closure switches provide a physical external control method. Automatic input detection can remain the primary operating method when the goal is to have the display respond directly to source availability.

Performance Highlights

• Supports 4K@60Hz HDMI signals with 4:4:4 color sampling.
• Supports HDR, with HDR10 and Dolby Vision listed in the product data.
• Reclocks and equalizes the HDMI signal before output.
• Detects both the onset and loss of an HDMI input signal.
• Sends an ON command when an input signal is detected.
• Sends an OFF command when the input signal is lost.
• Offers front-panel, Ethernet, and contact closure control options.

These functions place signal handling and display power control within one device. The supported refresh rate is 60Hz, corresponding to the stated 4K@60Hz signal capability.

What Makes It Different

The defining feature of the FC-18 is its ability to translate HDMI signal presence into display power commands. It does more than pass an HDMI signal: it monitors that signal and initiates ON or OFF control at the relevant transition. This enables a source-driven workflow in which starting the source can activate the display and removing the source signal can trigger shutdown.

The availability of three manual control paths adds flexibility around that automatic function. Local control is available from the front panel, network-based control is available through Ethernet, and external physical controls can be connected through contact closure switches. Users can therefore choose the control method that matches the way the connected display or projector needs to be operated.

Final Assessment

The Kramer FC-18 is a focused solution for controlling a display or projector according to HDMI source activity while handling a 4K@60Hz 4:4:4 HDR signal. Reclocking and equalization are integrated into the HDMI path, and HDR10 and Dolby Vision support are listed. Automatic signal detection reduces the need for repeated power-control actions, while front-panel buttons, Ethernet, and contact closure switches provide alternatives when manual or external control is required.
