HDR Compatible

When receiving HLG (Hybrid Log-Gamma) signals from a compatible imaging system, the LMD-XH550MD can accurately reproduce HDR images with a wider range of brightness levels, greater contrast and rich colours.

Local Dimming Technology

Sony’s unique Local Dimming Technology provides precise control over LED lighting sources for backlights in both light and dark areas. This technology allows for independent activation (ON) and deactivation (OFF) of LED lighting sources for each specific area, enabling to redistribute saved power from dark areas to boost the brightness of bright areas. The outcome is exceptional performance for HDR content, providing more natural images for an immersive viewing experience.

Wide, accurate colour reproduction

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

Anti-reflection panel structure

The monitor’s design minimises 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.

Advanced features for today’s clinical environments

Powerful imaging features of the LMD-XH550MD ensures optimal performance and usability in the OR and other demanding healthcare environments.

A.I.M.E.™ technology

Sony’s A.I.M.E. (Advanced Image Multiple-Enhancer) technology enhances the displayed images by adjusting the colour, contrast and visibility of shadow areas for an enhanced image analysis.

Clone output

The clone-output feature allows you to effortlessly see or record the same content that you are currently viewing when the second monitor or recorder is connected. Additionally, you have the flexibility to select the resolution of the clone-output, choosing between 4K or HD depending on your specific usage requirements.

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.
