Prerequisites

Supported Video Signals and Engine IO Modes

HDR is supported with Matrox SDI or IP boards, and with software I/O mode NDI. The HDR preview (see below) on desktop monitors, can be used with VGA engine versions as well.

To verify the correct output of your HDR design, we recommend using a calibrated SDI reference monitor. A spectrum and waveform analyzer helps measure and validate the correct output.

Requirements

HDR requires resolutions of 1080p or higher (HDR in 1080i is not supported). HDR rendering is highly performance and memory intensive, with the use of higher bit depth, and the additional conversion steps required.

Setup HDR Preview

For designing purposes, an HDR capable monitor can be used. However, to verify the final output, an HDR capable UHD SDI reference monitor is required.
Viz Engine can convert to scRGB colorspace to create an HDR window, provided by the Operating System (Windows 10 and 11). This requires an HDR capable Desktop Monitor.

To setup an HDR window preview, you need to enable Use HDR in the Windows Display settings:

• In Windows Control Panel, click on System → Display.

• Select the display, and turn on HDR:

  

• Make sure your display is capable of showing HDR content:

  

  Additional information is available in System → Display → Advanced display:

  

  We recommend installing a color profile provided by your display vendor, or do a manual calibration using the Microsoft HDR Calibration tool:

  

• In Viz Config Settings, enable HDR preview:

  

  The Scene Editor now shows the content in scRGB colorspace, providing an HDR preview of your scenes.

• To verify if the window is capable of HDR color space, move the slider in the SDR content brightness:

  

  If the scene editor window is not being affected by the slider setting, the HDR output is working correctly.
