Monitor - LX49xW - Image Diagonal

Large Display Area

With an image diagonal of 49” and a resolution of 1920 x 1080 pixels, the monitor is suited for displaying different image sources simultaneously. For example, DICOM X-rays and endoscopic images can be shown side-by-side in the surgical environment. The large image diagonal makes the monitor ideal for mounting on the OP wall and viewing images from a greater distance. Images can be scaled full screen, reproduced in their original size, or displayed in or next to one another with the PiP and PaP functions.

Monitor - LX491W - Flexible Usage

Flexible Usage

The monitor supports a wide spectrum of timings and can be adapted easily to the various signal requirements in the operating room. Together with its numerous input and output connectors, the monitor can be used in a variety of ways with established imaging systems. Depending on the procedure and requirements, users for example can quickly switch between endoscopic images, X-ray images in DICOM, and modality images with specialized timing, or combine these with other images.

Monitor - Comfortably View from Any Angle

Comfortably View from Any Angle

Wide viewing angles allow the monitor to be viewed from the side with minimal color shift, providing a clear view, especially when multiple people need to see the screen simultaneously.

Preset Look-Up Tables

The monitor is pre-calibrated in the factory. With five applicationoriented look-up table (LUT) presets and a user-configurable LUT function, the monitor is easy to install and maintain. It can be quickly adapted to the local viewing and lighting conditions or application preferences as needed.

User-Defined LUT Function

With the user-defined look up table (LUT), the default gamma model, color coordinates, and brightness of the LX491W can be adapted to individual requirements without additional sensors and software. With Force Mode, even the unknown timing of an older medical system can be analyzed and implemented in the monitor. As a result, even timing outside the standard range can be displayed on the monitor. This ensures compatibility, especially with older medical systems. And adaptations in the field, for example when replacing a device, become very easy.

Monitor - LX491W - Various Inputs

Numerous Video Inputs

The LX491W can be connected to imaging systems via the various video inputs, such as DVI, 3G-SDI, Composite, S-Video and VGA. The monitor can be simultaneously connected to both digital and traditional video signals (PAL, NTSC). If necessary, the video input settings can be adjusted using the OSD (On Screen Display) menu.

Monitor - LX49xW - PiP

Simultaneous Display of Different Image Sources

Thanks to the monitor’s widescreen format, the various input signals can be displayed in “picture-in-picture” (PiP) or side by side (PaP) orientations. This reduces the need for additional monitors, allowing users to view critical source image while simultaneously maintaining a view over other vital information.

Laminated Safety Glass for Easy Cleaning

The anti-reflective laminated safety glass ensures excellent image quality while protecting the monitor from scratch damage or liquid ingress during surgery or when cleaning and disinfecting the monitor.

Monitor - LX49xW - LED

LED Backlight

The monitor is equipped with an LED backlight that has been optimized for bright environments. LED technology offers a long lifetime expectancy even at high luminance settings.

Monitor - Quick Brightness Stabilisation

Stable Brightness and Instant Image Display

EIZO’s fully automated stability function uses an internal backlight sensor to quickly stabilize the brightness level at startup and to compensate for fluctuations caused by variations in ambient temperature and the passage of time.

Monitor - Fanless Silent Design

Fanless Silent Design

Engineered to dissipate heat without a fan, the monitor generates no distracting noises and does not circulate dust and germs or disturb the controlled laminar airflow within the operating room.

Monitor - LX49xW - Diagnostic Precision with Factory Adjustment

Diagnostic Precision with Factory Adjustment

To ensure the most accurate and consistent images possible, EIZO carefully measures and sets every tone on the production line to offer image quality tailored specifically to medical needs like gamma 2.2 and the DICOM Part 14 Standard.
