LMD-3251MT (LMD3251MT)

32-inch Full HD 3D LCD medical monitor


3D imaging is an increasingly important tool in today’s operating rooms. It’s a practical alternative to conventional 2D imaging, giving surgeons a stereoscopic view of high-resolution pictures captured with endoscopes and surgical microscopes.

3D offers an accurate, life-like visual experience, with improved depth perception and spatial orientation. This provides a more realistic visualisation of complex procedures.

The LMD-3251MT is a high-performance 32”* Full HD monitor that’s designed for use in medical environments. Connected to a 3D camera system, it displays smooth, high-resolution images that are viewed by surgeons and staff with the use of light, comfortable passive polarising glasses.

The monitor is fully compliant with medical safety standards for hospital operating room use. It’s also ideal for other environments where high quality 3D viewing is desired, from consulting rooms and clinics to conference halls and training suites.


See High-impact, Detail-packed 3D Images in Full HD 1920 x 1080 Resolution
Add an extra dimension of detail and realism when viewing images captured with today’s 3D endoscopic and surgical microscopy camera systems. Advanced polarising filter technology delivers smooth, flicker-free, easy-on-the eye stereoscopic images in Full HD that are viewed by surgeons and operating room staff wearing light, comfortable passive glasses.
View with Light, Easy to Wear 3D Glasses
Stereoscopic Full HD images can be viewed with a choice of passive 3D glasses that require no power source and can be worn with minimum fatigue over extended periods of time. The BKM-30G comfortably fits most facial shapes, and features a specially designed nose pad and temple tips that hold the glasses securely in place. The super-lightweight BKM-31G ‘clip-on’ model attaches to normal glasses and features a convenient flip-up design.
Energy-efficient, Environmentally Friendly Panel with LED Backlight
The panel’s energy-efficient LED backlight offers high image brightness as well as lower power consumption than conventional CCFL designs. The mercury-free backlight also reduces potential environmental impact at end-of-life disposal.
3D/2D Switchable
As well as high-resolution 3D images, the LMD-3251MT can also display images from conventional 2D surgical camera systems in Full HD resolution.
Clear Images with a Wide Viewing Angle
The LMD-3251MT employs 32” α-Si Active Matrix TFT widescreen display panel that minimises colour shift from all viewing angles. This helps to achieve consistent image viewing when used in surgical applications.
Coated Panel Reduces Light Reflection
The AR coating reduces reflections from ambient light, ensuring high contrast even when used in bright lighting conditions.
Natural Gradation and Accurate Colour Reproduction
An advanced 10-bit digital video signal processor delivers smooth, natural tonal gradations for extremely life-like, accurate image reproduction.
ChromaTRU™ Colour Matching for Accurate, Dependable Colours
The LMD-3251MT ensures that colours seen by the surgeon are an accurate representation of the subject. Precise factory calibration of RGB co-ordinates for each panel ensures the highest levels of true, consistent colour reproduction across multiple monitors. Further calibration maintains white balance at a uniform colour temperature throughout all grayscale levels.
Colour Temperature and Gamma Curve Selection
Display colour temperature can be selected with three preset colour temperate modes (D93, D65, D56) and five user-defined settings. There’s also a choice of CRT 2.2 and DICOM gamma curve settings to meet the needs of different modalities.
Wide Range of Display Modes
The LMD-3251MT supports a variety of 2D display modes, including Side-by-Side (SBS), Picture-out-Picture (POP) and Picture-in-Picture (PIP). It allows display of images from multiple sources on a single monitor. Adding the optional BKM-256DD DVI-D input adaptor supports display of images from two simultaneous DVI input signals.
Mirror Image for Convenient Side-by-side Working
The monitor’s mirror imaging function lets an assistant view a ‘flipped’ mirror image of the surgeon’s own display. It is ideal for procedures where two surgeons are working at opposite orientation points to the patient. With this feature, surgeons no longer have to stand side-by-side, sharing a single display as they do in a conventional operating room.
Protected Controls
Inadvertent operation of the control panel can be prevented by the display’s key inhibit function. Pushing the Control button on the control panel turns off LED switch lights and overrides switch functions.
Extensive 2D and 3D Input Capabilities
The monitor accepts a wide range of input signals as standard, including composite, Y/C, RGB/component, HD15 and DVI-D. Dual expansion slots for up to two optional input boards allow the LMD-3251MT to be used as a multi-format monitor, including support for 3G/HD-SDI.
Black Bezel for Optimised 3D Viewing
The display’s unique black bezel design provides an excellent viewing background and gives surgeons a clear, optimised view of 3D images that are being displayed.
Compliance with medical standards
This product is distributed to the US and EU as a medical device and satisfies product safety standards (e.g. IEC 60601-1). For more details, please contact your nearest Sony sales office or an authorized dealer.
