DM-RMC-4K-SCALER-C/-DSP:
4K DigitalMedia 8G+®Receivers and
Room Controllers with Scaler
Introduction
The DM-RMC-4K-SCALER-C and DM-RMC-4K-SCALER-C-DSP provide advanced
one-box interface solutions for a single display device as part of a complete Crestron®
DigitalMedia™ system. Each device functions as a DM 8G+®receiver, 4K/60 video scaler,
and control interface, providing a single HDMI®output. In addition, an analog audio output,
Ethernet, RS-232, IR, and relay control ports are provided. Built-in scaling enables the
connected display to handle virtually any video signal—including 4K and Ultra HD.
The DM-RMC-4K-SCALER-C-DSP also provides internal surround sound processing.
For additional information about the various features and capabilities of the
DM-RMC-4K-SCALER-C and DM-RMC-4K-SCALER-C-DSP, refer to the product
specification sheet on the corresponding product page of the Crestron website
(www.crestron.com). For installation information, refer to the DM-RMC-4K-SCALER-C/
DM-RMC-4K-SCALER-C-DSP DO Guide (Doc. 7708) at www.crestron.com/manuals.

Configuration
This section provides configuration information about the following:
•Video wall processing
•Adjustable underscan and overscan
•User-selectable output resolution
•Standby timeout
•Display mode
•EDID
•Connection to a third-party HDBaseT transmitter
Video Wall Processing
Multiple DM-RMC-4K-SCALER-C units can be combined to configure a video wall
composed of up to 64 individual displays (up to eight columns of displays by eight rows of
displays). A separate DM-RMC-4K-SCALER-C is required for each display, and a
DigitalMedia switcher with sufficient DM 8G+ outputs is also required. Each
DM-RMC-4K-SCALER-C provides zoom capability and bezel compensation on its output to
display a portion of the source image.
To configure a video wall, use the Crestron Toolbox™ DMTool or use SIMPL Windows as
discussed in the following sections.
Configuration Using DMTool
An overview of the steps necessary to configure a video wall using DMTool follows.
NOTE:
For detailed information, refer to the Crestron Toolbox help file.
1. Connect to the DigitalMedia switcher.
2. Connect to the desired DM-RMC-4K-SCALER-C.
3. Open the Setup window of the HDMI output.
4. In the Video Settings dialog box, configure the video wall. In addition, configure
bezel compensation to compensate for image loss at the edges of the display.

Video Settings Dialog Box—Video Wall and Bezel Compensation Configuration
5. Repeat steps 2-4 for each DM-RMC-4K-SCALER-C that connects to a display for
inclusion in the video wall.
Configuration Using SIMPL Windows
An overview of the steps necessary to configure a video wall using SIMPL Windows follows.
NOTE:
For detailed information, refer to the SIMPL Windows help file.
1. Configure slot 3 for a DM-RMC-4K-SCALER-C Scaler by setting the
<Scaler_Out_Wall_Mode>
,
<Scaler_Out_Horizontal_Bezel_Compensation
>,
and
<Scaler_Out_Vertical_Bezel_Compensation>
analog input joins to the
desired values.
2. Repeat step 1 for each DM-RMC-4K-SCALER-C that connects to a display for
inclusion in the video wall.
Adjustable Underscan and Overscan
If content does not fit properly on a display, adjustments to underscan or overscan may be
desired. Adjustments can be made up to 7.5%. Adjusting the underscan reduces the image
size by the specified percentage so that the entire video frame is displayed. Adjusting the
overscan expands the image size by the specified percentage so that extra information
around the edges is not displayed.
To adjust underscan and overscan settings, use DMTool or SIMP Windows as discussed in
the following sections.
