The Orchid OR-841-HDSDI is a single 8.4” fully featured camera-top and field monitor system. The OR-841-

HDSDI offers built-in Waveform Monitor, Vectorscope, Audio Bars, Built In Speaker with audio outputs, and 

several diagnostic tools. This monitor is ideal for use as a camera top or field camera assist monitor. The OR-841-

HDSDI is equipped with two HD/SD-SDI inputs with switched output. Diagnostic tools include our exclusive 

ClipGuide  feature,  16  Tri-Color Audio  Bar  Graph  meters  with  peak  hold  and  numeric  display  of  headroom 

and peak levels, and real-time analysis of color space conversion gamut errors. Other standard features include 

factory calibrated screen, easy-to-navigate onscreen menus with RotoMenu control, 9 assignable function keys,  

adjustable color temperature, aspect ratio settings, a variety of screen markers, blue-only mode, monochrome 

mode, H/V delay, and 7 assignable GPI inputs. 

The OR-841-HDSDI features an all-digital TFT-MegaPixel active matrix LCD system. The LCD panel features 

a nominal brightness of 400 cd/m

2

 and a contrast ratio of 400:1 making each display ideal in a variety of 

environments and lighting conditions. 

The built-in Vectorscope allows users to monitor color gamut range in real 

time. It displays in full color and can also be displayed in various sizes, 

positions, and transparency options. The Vectorscope has adjustable gain 

from 1x to 5x.

The built-in waveform monitor (which includes adjustable White and Black 

clip level indicators) can be displayed in various aspect ratios, positions, 

and transparency options. The Waveform Monitor not only monitors 

luminance, but can also warn the user for out-of-range conditions such 

as overexposure or “blacker-than-black” errors with fully user-adjustable 

warning limits. 

The ClipGuide function operates with both the Waveform display and 

Monochrome/Color picture display. Both the upper and lower ClipGuide 

levels are user-adjustable in order to accurately display over-and-under 

exposures during different shooting conditions. For example, the upper 

ClipGuide limit may be set to 85 IRE and the lower limit to 10 IRE. With 

these settings, any exposures over the set limit of 85 IRE will display red 

on both the Waveform and picture (if selected). The same will be true for 

blacks under 10 IRE.

Included in the ClipGuide menu are settings for monitoring color gamut errors, which can occur in color space 

conversion.  Any data exceeding these values will be displayed as Yellow in the picture. The factory preset for C 

limits are 16 and 240 according to ITU-R BT.709. Typically, these values should not be exceeded during normal 

video production.
