is unseen in broadcast and post-production environments. Be it for camera or lighting
professionals, editors, colorists or post-production staff, anyone who is highly
demanding about colors will value Barco’s RHDM series as indispensable references.
Colors that last
While traditional reference monitors need to be recalibrated at least weekly, the
RHDM-family will keep their colors lasting for months on end. Barco's reference monitors feature advanced calibration and stabilization technology, integrated into the
display’s electronics, which tracks color performance in real time and corrects for any
changes related to temperature and aging.
Excellent motion handling
With Barco’s RHDM series displays, you can do full justice to the action scenes you
produce. Thanks to the high-speed 120 Hz panel, proprietary LCD speed-up algorithms and scanning RGB-LED backligh technology, the RHDM series prevent
motion blur and judder. Additionally, a black line-insertion algorithm presents native
interlaced images without any de-interlacing artifacts. This results in excellent motion
handling and lifelike motion scenes with a CRT-like quality.
Color accuracy
At Barco, we understand the complexity of color. And just like many other color-critical professionals, we understand that judging color is an every-day challenge. The
RHDM-1701 and RHDM-2301 combine Barco’s long-standing expertise in the field of
color accuracy with the most recent and cutting-edge technology around, such as the
RHDM series’ native 10-bit panel (22-bit with proprietary dithering), calibrated RGBLED backlights, unique 48-bit processing and embedded 3D-LUT cross-talk

RHDM-B series
RHDM-1701B and RHDM-2301B are reliable references for master control
rooms, camera control, camera shading, signal quality checks, technical
rooms etc, both in TV studios as well as
OB vans.
Camera control/shading
At the time of shooting, Barco’s RHDM-B series are the reliable references for program
directors, colorists and camera and lighting staff. During real-time color judging, the
RHDM-B series provide continuous color stability, perfect representation of grayscales,
deep darks and correct pastel tones. The split-screen functionality helps compare and
adjust two cameras or other sources side by side on the same monitor with the highest picture quality. The monitors also support In-Monitor Display functionality and two
tally lights on the actual LCD, hereby saving valuable rack space.
Field productions
In OB vans and ingest & transmission monitoring environments, RHDM-1701B and
RHDM-2301B users benefit from the display’s robustness and system stability. The
RHDM-B series can easily withstand temperature cycling conditions, so that frequent
calibration is not necessary. They also feature various modes for video handling and
motion blur reduction, which allows to correctly judge fast moving scenes.
Mixing and master control
In preview and master control environments, the RHDM-B series are the most reliable
and stable reference for source quality validation and for program and output monitoring. The monitors also support In-Monitor Display functionality and two tally lights
on the actual LCD.
Barco’s RHDM-B series provide the most reliable colors and CRT-like image speed. The
monitor latency is always presented on the on-screen display, allowing sound editors
to work more efficiently.
Technical room
For delivery and ingest monitoring, Barco’s RHDM-B series offer a stable reference for
color grading and speed judgments across different workflows.
Technology highlights:
• Supports all standard SD and
HD-SDI signal
• Optional Dual Link
• Optional 3Gb/s HD-SDI
• Supports TSL 3.1 and 4.0 serial
tally/UMD protocols
Transport formats
The RHDM-B series are ideal display solutions for checking HD to SD conversions and
decompression artifacts. The displays offer a de-interlace and native interlaced handling option, which allows validating multiple application formats.
Tally & UMD control
Dynamic Under Monitor Display (UMD) control with the TSL protocol and tally lights
show valuable indications to anyone working in a television studio, being it in front of
or behind the camera. Barco’s RHDM series support both, either on spare areas onscreen (RHDM-2301), or in overlay mode over the picture (RHDM-1701).

RHDM-P series
Film acquisition
The RHDM-P series are the perfect reference monitors for Directors of Photography
(DoP) on set during film acquisition, as well as for dailies processing. The Grade-1
color accuracy and stability means that two RHDM-P series monitors will show identical pictures even on two distant sets. The support of 3D-LUTs allows a better preview,
pre-post and faster creative decision making on set.

music etc.
Visual effects
Scanning RGB-LED backlight technology, a 120Hz LCD panel and native interlace mode
make the RHDM-P series an excellent reference for motion handling.
DVD and Blu-ray mastering
The RHDM-P series are reliable references to validate a digital intermediate and its
derivatives (DVD, Blu-ray, digital cinema masters etc.)
3D-LUT support
Reference monitors used in post-production of feature films need to visualize how a
final film print will look like. In order to simulate this, a 3D-LUT must be applied to the
input signal, either in an external processor, or internally in the monitor. Barco's
RHDM-P version is able to handle custom 3D-LUTs. Formats from Filmlight, Cinespace
and Autodesk are now supported as a standard feature.
Technology highlights:
• Supports Dual Link HD-SDI
• Supports 3Gb/s SDI
• Custom RGB primaries in (x,y)
• Supports custom 3D-LUTs

making a difference
Wide color gamut
Barco's RHDM-family has RGB-LED backlights with separate red, green and blue
LEDs. This results in a wide color gamut (wider than required for Rec.709). This color
gamut is then transformed to the required display gamut (e.g. Rec.709, SMPTE, EBU).
Wide color gamut
Worry-free auto-calibration
To counteract the effects of ambient temperature and backlight aging, the RHDM
series have integrated calibration and stabilization technology, including a spectrometer, various color sensors and temperature sensors. This means that the
displays’ colors and white point are constantly monitored and corrected in real time in
case of imperfections. What’s more, there is no need to recalibrate the monitors for at
least a one-year period.
Via an easy user interface, the embedded spectrometer enables manual control of the
display white point in actual (x,y) coordinates. In the RHDM-P versions, also the primaries can be adjusted so that film post-production users can benefit from the large
LED gamut. The white point balancing is directly performed on the backlight. Unlike
typical R-G-B gain controls in traditional monitors, the contrast is preserved and no
display levels are discarded. Manual calibration is as simple as typing in the required
white-point color coordinates, for example those measured on a CRT.
Motion blur prevention
Traditional LCD monitors present blur artifacts as a result of the deinterlacing mode,
which typically builds up the image in a line by line drawing process. Barco's RHDM
series counteract this by reducing the ‘hold’ effect created by LCDs. First of all, the
monitors have a fast 120Hz panel. In addition, the RHDM series’ scanning backlight
system makes sure that only the stable LCD information is illuminated.

Finally, to avoid the typical de-interlacing artifacts, the RHDM-family also allows for
black line insertion for native interlaced representation. In practice, this means
that each field of interlaced video (odd and even) is displayed separately and the corresponding second fields are blanked with black lines.
