The Murideo SIX-G digital video generator can be automatically controlled by the Calman Display Calibration Software to produce measurement and calibration test patterns for SDR and HDR displays.
Calman Required version
- 5.7.0 or later (v 5.8.1 or later for full HDR support)
Murideo SIX-G Supported Firmware
- Version 2.42 or later for full HDR support
Murideo SIX-G Control Ports
- USB
- RS-232 serial
Murideo SIX-G Driver Installation
Connect with a USB cable:
- Install the Murideo SIX-G USB FTDI driver and connect the Murideo SIX-G to the Calman computer with a USB cable. (Seen by the computer as a com port.)
Note: The FTDI USB driver is available as part of the Calman Device Driver Pack (Download Link) or from the FTDI web site (Link). - When the driver is properly installed, the Murideo will be listed in Device Manager under Ports (COM & LPT) as “USB Serial Port (COMx).” If it is not listed that way, the driver is not yet properly installed.
Connect with an RS-232 null-modem serial cable:
- If the Calman computer has an RS-232 serial port, you can connect the Murideo SIX-G directly to the Calman computer with a null-modem female DB9 to 3.5mm phone plug cable (this is a slower connection).
Calman connection to Murideo SIX-G
Important: Murideo SIX-G units with version 2.xx firmware are able to select 3840×2160 resolutions in a “4K Geometry” mode. If the unit is in its 4K Geometry mode while attempting to connect to Calman, an error message will be produced that states “Firmware or application not up to date, check for a newer version. To avoid this error and connect normally, switch the Murideo SIX-G out of its 4K Geometry mode before connecting to Calman.
To connect the Murideo Six-G to Calman:
- On the Calman Source Settings tab, click the Find Source button.
- On the Calman Find Source dialog, select Murideo – SIX-G
- Select the appropriate Com Port (check Device Manager for the assigned com port).
- Click Connect on the Find Source dialog.
Calman Source Settings Options
When the Murideo Six-G is connected as a Calman test pattern source, the following Settings options on the Calman Source Settings tab should be set according to the type of display being measured or calibrated.
Refer to specific display model information to guide these settings on the Source Settings tab.
- Window Size
- Delay (Optimize for specific display characteristics)
- Pattern Size
- Pattern APL
- Resolution (match display’s normal drive signal)
The Source Settings options are detailed below for each of the following types of content:
- VESA sRGB SDR content (RGB computer monitors)
- HDTV SDR content
- HDR10 HDR content
- HLG HDR content
- Dolby Vision HDR content
Note: After changes are made on the Source Settings tab, the VideoForge PRO output mode does not change until Calman selects the first test pattern to be displayed
VESA sRGB SDR Content Calibration (RGB computer monitors)
VideoForge PRO Source Settings options for VESA sRGB SDR content:
- Color Format: RGB Full
- Bit Depth: 8-bit
- BT.2020: Disabled
- HDR: Off
HDTV SDR Content Calibration (video monitors & consumer TVs)
VideoForge PRO Source Settings options for HDTV SDR content:
- Color Format: YCbCr 4:2:2
- Bit Depth: 10-bit
- BT.2020: Disabled
- HDR: Off
Note: When enabling BT.2020 color space for SDR, the Color Format should be set to “RGB Limited,” as the VideoForge PRO does not support correct BT.2020 triplets for YCbCr output.
HDR10 HDR Content Calibration
VideoForge PRO Source Settings options for HDR10 HDR content:
- Color Format: RGB Limited
- Bit Depth: 10-bit
- HDR: HDR10
- EOTF: SMPTE ST 2084
- Mastering Display Primaries: P3
- Mastering Display White Point: D65
- Mastering Display Max Luminance: 1000 (540 for OLED)
- Mastering Display Min Luminance: 0.005 (0 for OLED)
- MaxCLL: 1000
- MaxFall: 400
Note: When enabling HDR10, the Color Format should be set to “RGB Limited,” as the VideoForge PRO does not support correct triplets for YCbCr output.
HLG HDR Content Calibration
VideoForge PRO Source Settings options for HLG HDR content:
- Color Format: RGB Limited
- Bit Depth: 10-bit
- HDR: HDR10
- EOTF: HLG
Note: When enabling HLG, the Color Format should be set to “RGB Limited,” as the VideoForge PRO does not support correct triplets for YCbCr output.
Dolby Vision HDR Content Calibration
VideoForge PRO Source Settings options for Dolby Vision HDR content:
Note: For Dolby Vision HDR mode, the VideoForge PRO resolution must be set to 1080p.
- Color Format: RGB Full
- Bit Depth: 8-bit
(The patterns are actually 4:2:2 YCbCr 12-bit. Dolby Vision tunnels the YCbCr 12-bit patterns through the RGB 8-bit signal path.) - HDR: Dolby Vision
- Dolby Vision Mode:
- Perceptual – To be selected when using the Dolby Vision workflow (not to be used with the Dolby Vision Custom workflow).
- Relative – To be used with the Dolby Vision Custom workflow, to perform the Metered Calibration steps.
- Absolute – To be used with the Dolby Vision Custom workflow, to perform the Post Calibration steps.
- Specialty Patterns: In Dolby Vision mode, the VideoForge PRO specialty patterns display to the TV screen, but they are SDR, not Dolby Vision HDR.
