42 inch 3D Cinema Technology Monitor

The Zunzheng CM420TD is a 42" Multi-Format reference monitor with 3G/Dual-Link/HD/SD-SDI, Component, Composite, & DVI-I Inputs. As a flagship CM series monitor the CM320TD delivers the highest level of performance available within the Zunzheng product lineup. This unit features full 12-bit video processing and a 10-bit panel capable of reproducing over 1.073 billion colors on screen. The monitor is also equipped with a passive circular polarizer and in-monitor multiplexing allowing for easy and affordable 3D monitoring in addition to its already capable 2D monitoring modes. The CM420TD provides support for virtually any signal format from NTSC/PAL to HD and 2K, including advanced 12-bit, 4:4:4, and XYZ signal formats. This monitor was purpose built for color critical evaluation in the most demanding applications within post production, broadcast, and on set monitoring environments.


Color space management is handled by our CFE2 Color Fidelity Engine. This advanced second-generation 64x64x64 Matrix 3D LUT processor ensures a high degree of accuracy in any color space mode. Select between Rec 790, EBU, SMPTE-C, DCI-P3, Native Wide Gamut, and Custom User Generated color spaces. CFE2 supports custom calibration LUTs as well as DIT LUTs that do not require profiling of the panel with a probe before import (e.g. BlackMagic Design Film Mode to Rec 709 LUT, LogC to Rec 709 LUT, etc.)


The CM420TD is equipped with 3Gbps SDI (SMPTE 425M-AB) & Dual-Link SDI (SMPTE 372M) inputs, which provide support for advanced formats including 4:4:4 RGB, 4:4:4 YCbCr, and 4:4:4 XYZ signals. With support of both Level A and Level B 3Gbps SDI the CM172 is compatible with virtually all 3Gbps SDI sources and provides many advanced viewing modes for multiplexed (2x SMPTE 292M) Level B signals as explained here.


All Zunzheng monitors come standard with 13 Mode On-Screen Scopes. Up to two types of Scopes can be displayed simultaneously and can be toggled on/off instantly with a single button press. Scope Windows can be displayed in any of 6 onscreen locations and the two scope windows can be stacked on top of each other or sit side by side for maximum flexibility. Zunzheng is also one of the few companies to provide this scope functionality across all inputs, even DVI. This means that full scope functionality is possible while using many of today’s most popular HD-DSLR cameras that only offer HDMI output.



Built-in audio disembedder and internal speakers allow you to listen to any single channel or stereo pair of embedded audio channels pulled from HD/SD-SDI video on the internal speakers or via the monitor’s audio line out. This disembedded audio is always delayed by the exact amount of video processing and pixel response time to ensure perfect lip sync for audio critical applications. Meter all 16 channels of embedded audio on screen either in a horizontal layout (VU with dB readout) or next to one of the Scope Mode Windows displayed in a vertical layout (PPM).
