Section 9 – 3D Support

Radiance 2022 and Radiance 2042 rev 082813

Separate Left and Right

The Radiance can accept HDMI 1.4 “3D” video and output either the left-eye or right-eye image for a dual

projector 3D system that uses passive 3D glasses. This 3D system configuration uses two Radiance video

processors.

3D Output Settings

The Radiance has support for all of the commonly used 3D video sources. If you connect a HDMI 1.4a

compliant 3D video source and compliant 3D display, to the Radiance, you should automatically get a 3D

image, using the Radiance default settings.

The Radiance has settings that you can use to display 3D video, using non-compliant 3D video sources and

displays. The Radiance has settings to optimize the video on your 3D display. The Radiance also has

settings to display 3D video on some 2D displays (See section titled “3D Support for 2D Displays” for further

details).

3D Output Setup Menu

You can select the 3D output settings based on the input number, input memory, and input video mode. For

any of the three input conditions you can select ‘All” to apply the output setup to multiple input conditions.

When making settings that apply to multiple input conditions you can leave any of the output settings

unchanged by selecting the ‘-‘ option for that output setting. Press “4” for ‘All’ and press “5” to see the

current settings. The command is:

3D Output Mode = Auto

By default the output is set to “Auto 2,1.” The selection “Auto 2,1” means the Radiance automatically reads

the EDID for the devices connected to both outputs, giving priority to Output 2, and automatically selects

the appropriate output resolution. That is, if an active device is connected to output 2, the EDID from that

device is read to determine the optimal video output resolution and the Radiance automatically selects the

specified resolution. If no device is connected to output 2, or the device connected to output 2 is turned off,

the Radiance uses the EDID from the device connected to Output 1 and sets the output resolution

appropriately. Output 1 can have priority by selecting “Auto 1,2” from the

Video Output Select Menu

For “Auto” modes the output vertical rate is selected based on the input vertical rate. For example, input

formats 480i60, 720p60, 1080i60 automatically select a vertical output rate of 60 Hertz. Input formats

576i50, 720p50, and 1080i50 automatically select a vertical output rate of 50 Hz. For a 1080p24 input

format a 24 Hz output vertical rate is selected if the display supports a 24 Hz output vertical rate, otherwise

a 60 Hz rate is selected.

If the priority output is connected to a 3D device, and the secondary output’s device is not 3D, when a 3D

source is detected the Radiance automatically disables video to the 2D output.

For analog displays and digital displays, that do not properly support EDID, the output mode must be

selected.

3D Output Mode = Specific Format

The Radiance will convert all 3D input formats to the specified 3D output format. For example all 3D input

modes can be converted to a 1080p60 side-by-side output mode.

3D Output Type = Auto

The Radiance has support for all of the commonly used 3D Types (Frame Packed, Side-by-Side, Top-

Bottom, and Frame Sequential). When the output ‘Type’ is set to ‘Auto’ the Radiance will convert all 3D

modes and types to HDMI 1.4a mandatory 3D format.

3D Output Type = Specific 3D Type

The Radiance will convert all 3D input types to the specified 3D output type. i.e. All 3D input types can be

converted to 3D Frame Sequential to drive a CRT display/projector.
