  • Overview
  • Download
Traditional LCD monitors integrated LCD panel, video & audio processor, function controller and power supply into one cabinet, which not only increase their volume and weight, more importantly, the LCD panel will produce heat in working conditions, the power consumption will be increased with panel size increases which caused more heat generated . In addition, the heat from video processing modules and peripheral components built-in the video processing system will greatly reduce stability and service life of the monitors.

Split type design
Apart the display (LCD panel) from video & audio processing and master control system, minimize the heat of monitor and make its performance more stable.

More portable
Split type design, minimize the size and weight of monitor to make it more portable.

Easily For Maintenance
If a failure appears, just need to inspect, repair or replace the components built in the bottom case, rather than disassembling the whole unit, which will reduce maintenance costs definitely.

More compatible
Choose “video & audio controllers” with different functions according to  the application requirements at current stage. We just need to buy corresponding “video & audio controller” instead of LCD panel if we want to upgrade the monitor, which will greatly reduce users’ purchasing cost.


Screen Protector
To prevent the LCD screen from being scratched or impacted, the innovative designed separate protector is only 300g, made of the special material with characteristics of good optical transparency, high resistance to impact,  and with excellent thermal stability, creep resistance, cold resistance, electrical insulation and flame resistance. Installation and removal is simple. Not only can effectively protect the LCD screen from being impacted, you can also make it as a transparent drawing board  to help the producer to preset the position when shooting the advertisement etc.

Extensible Sunhood
It is sepecially designed for RW1850HD. This designed is based on iTechLCD previous sunhood technology,and fully considered the strong light inteference to the monitor in outdoor shooting. The secondary extension design of the sunhood could solve the strong light intefering problem.

Video/audio signal auxiliary detect function
In order to get accurate luminance and chroma information, RW1850HD internally installed high sampling rate brightness waveform, RGB waveform and vector scope. It display the real-time luminance and chroma, which work as photographer's and technician's reference tool to guarantee the record video information within standard luminance range.
