Exceptional image quality

The LMD-XH550MT (55-inch) and LMD-XH320MT (32-inch) display bright, high-quality 4K Ultra HD images in either 3D or 2D with a resolution of 3840 x 2160 pixels (16:9 screen aspect ratio). Sony’s unique local dimming panel technology ensures high contrast images that reveal fine detail in highlights and dark shadow areas. In addition, the anti-reflective panel structure helps surgical teams see clearly, even under the glare of direct lighting in the OR.

High brightness and contrast

The LMD-XH550MT and LMD-XH320MT feature Sony’s unique Local Dimming Technology, which controls the LEDS individually according to the scene and optimizes the brightness. This enables a peak brightness (panel specification) of 1,500 cd/m2 (LMD-XH550MT) / 1,750 cd/m2 (LMD-XH320MT) with a contrast ratio of 1,000,000:1.

HDR compatible

When receiving HLG (Hybrid Log-Gamma) signals from a compatible imaging system, the LMD-XH550MT and LMD-XH320MT can accurately reproduce HDR images with a wider range of brightness levels, greater contrast and rich colors.

SDR and HDR images are shown, with HDR image displaying a wider range of brightness levels

Anti-reflection panel structure

The monitor’s design minimizes reflected glare in brightly lit ORs, including distracting reflections from surgical lights. The panel’s anti-reflection structure reduces light dispersion, ensuring high-contrast images under a wide range of illumination conditions and viewing angles.

Wide, accurate color reproduction

The monitor’s advanced LCD panel and signal processing technology support highly consistent, accurate reproduction of a wide color gamut. This complies with ITU-R Recommendation BT.2020 that represents a significantly wider gamut than the BT.709 color space, allowing superior color reproduction and more realistic visualization.

Extensive 3D display options

The LMD-XH550MT and LMD-XH320MT can display 3D and 2D signals in HD and 4K. Connections for SDI (12G/3G), Display Port, DVI, and HDMI signal inputs support a variety of different 3D and 2D formats such as side-by-side, line-by-line, and top & bottom. Dual stream is available when accepting an HD 3D signal via SDI. 4K dual stream via two 12G-SDI inputs is also available (XH550MT only). 3D/2D operating mode can be changed directly with the button on the front panel, with selected mode indicated on the display.

Advanced features for today’s clinical environments

The design and powerful imaging features of the LMD-XH550MT and LMD-XH320MT ensure optimal performance and usability in the OR and other demanding healthcare environments.

A.I.M.E.™ technology

Sony’s proprietary A.I.M.E. (Advanced Image Multiple Enhancer) technology enhances the visibility of displayed images to assist surgical teams. Structure Enhancement improves recognition of the object’s outline, allowing structures to be seen more clearly with increased sharpness. Color Enhancement allows tonal differences to be manipulated for greater visibility. Shadow Enhancement improves visibility of details in dark areas.

two surgical images are shown next to each other with A.I.M.E. on and off. ON image is seen more clearly with increased sharpness.

Multiple display modes

Alongside a choice of standard display modes – side-by-side, picture-in-picture (PIP) and picture-out-picture (POP) – V Full mode lets users change smaller POP images to be enlarged and displayed full screen. Either or both POP images can be enlarged by the user as required.

Note: 3-screen display is available only for 2D images.

Clone output

The exact image displayed on the monitor – including display settings such as A.I.M.E. or picture-in-picture – is output for simultaneous viewing on a secondary display. This allows OR staff and students to view the same content that’s being viewed by the surgeon on a bigger display. The clone output can be rescaled from 4K to HD and vice versa; it can also be used to convert from 3D to 2D if a connected monitor or recorder only accepts 2D input signals. HDR (HLG gamma) can be converted to SDR for monitors or recorders that only accept SDR signals.

Optimized design for simplified installation and ease of use

The LMD-XH550MT and LMD-XH320MT are designed for easy, flexible installation and reliable, user-friendly operation in a wide range of demanding clinical environments.

Designed for easy hygiene

The display’s smooth surface, streamlined back shape and small vents allow easy wiping of liquids and gels off the LCD panel, control buttons, and rear cover, supporting high standards of disinfection and cleanliness in the OR.

Intelligent cabling

All signal cable ports face downwards to allow neatly organized cable connections. Three cable access points with covers further simplify cabling to meet a wide range of installation needs.

Extensive connections

Connections are provided to support a wide range of 3D and 2D video signal inputs from clinical modalities, including SDI (12G/3G), Display Port, HDMI and DVI.

Intuitive navigation

LED backlighting only highlights active control buttons on front panel to guide the user easily and prevent misoperation, also in dark environments. Custom buttons can be assigned to commonly used functions.

Dual AC/DC powering

(LMD-XH320MT only) A choice of direct AC power or DC powering via an optional AC power adapter (AC-300MD sold separately) gives extra installation flexibility in clinical environments.

Hands-free control

Using an optional footswitch (FS-24 available separately) surgeons can easily operate frequently used menu functions such as A.I.M.E. on/off, port A/B, PIP/POP, flip pattern and 3D/2D.
