• Fast Mode

This function minimize the interlaced video processing time delay. This mode is also useful when displaying fast-motion interlaced video content and when reducing the delay between video and audio. (* OBM-U170 model is only supported.)

• Color Space / HDR / Gamma Comparison (Side by Side, Wipe position)

This unique function allows users to compare the two different color spaces, gammas, HDR / SDR, camera logs and any other color settings side by side simultaneously.
The comparison area can be moved and selected by using the vertical wipe pattern.

Color Space & Gamma Comparison image

• 4K Waveform Monitor and Vector Scope Display

These features enable users to monitor sources using the internal Waveform and Vector Scope.
Waveform Wide mode* is supported, and both Waveform and Vector Scope can be displayed simultaneously.

• High Dynamic Range(HDR) Display Function

The OBM series provides the function to display the High Dynamic Range footage.
Postium HDR function allows users to view both highlights and shadow detail of scenes at tha same time, thus resulting in more natural and realistic images.
The OBM series supports PQ EOTF (SMPTE ST 2084), Hybrid Log Gamma and S-Log3.

High Dynamic Range(HDR) Display Function image

OBM-HDR provides the function of comparing HDR and SDR(Standard Dynamic Range) on the displayed image on the OBM series simultaneously.
