Monitor - LX550W - Uniform Image Quality

Uniform Image Quality from All Angles

This large-format monitor is fitted with a high-quality IPS panel characterized by a very wide viewing angle. Image reproduction is thus made even more precise and efficient, regardless of the viewing angle.

Monitor - LX550W - On-Site Adjustment

Quick On-Site Adjustment

The built-in On-Screen Display (OSD) can quickly adjust the monitor to different image types and the prevailing ambient brightness at the installation site. Service technicians can also quickly and easily adjust the grayscale display on site to suit their needs.

Monitor - Everything in a Single Glance

Everything in a Single Glance

Compared to solutions with multiple monitors, there are no regional color differences or obtrusive bezels between individual image sections on large screen monitors with high resolution, so that users can conveniently display important information on a single screen.
Monitor - LX550W - PiP

Superimposed Image Display for Emergency Signals

With the Picture-in-Picture (PiP) function multiple source images can be shown at the same time on the LX550W, so as to display a live signal directly on the monitor in an emergency, for instance.

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.

Monitor - Quick Brightness Stabilisation

Quick Brightness Stabilization for Instant Viewing

EIZO's fully automated stability function makes use of 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 - LX550W - Consistency with DICOM Part 14 Calibration

Consistency with DICOM Part 14 Calibration

The monitor is calibrated to comply with DICOM Part 14 to offer rendering consistency over time.

Monitor - Brightness Uniformity for Constant Brightness Across the Screen

Brightness Uniformity for Constant Brightness Across the Screen

The Digital Uniformity Equalizer (DUE) function provides optimum backlight luminance uniformity which is considered difficult to attain due to the characteristics of LCD monitors, especially with larger screen sizes.

Monitor - Work Safely with Minimal Picture Delay

Work Safely with Minimal Picture Delay

With images displayed on the screen in real time, time critical aspects of image distribution are addressed to ensure, for example safe catheter localization during insertion into an artery.

Operational Reliability with Redundant Components

With its redundant components architecture (2 power supplies, 2 backlights), EIZO ensures a high degree of operational reliability. A monitoring function can be configured to notify the X-ray system if, for example, operating conditions become critical or a component fails.

Monitor - LS580W - Keep Your Monitor Lit Longer

Keep Your Monitor Lit Longer

The monitor is equipped with two independent LED backlights that offer a significantly longer service life over conventional CCFL backlights. In addition, you can maintain high brightness while simultaneously lowering power consumption. Since the LED backlights are mercury-free, they will also reduce any potential impact on the environment when they are disposed of.

Monitor - Arm Mountable VESA Compliance

Installation on a VESA Ceiling Suspension

Compliance with the VESA standard enables attachment to existing mounting accessories.

Optional LCD Panel Protector for Easy Cleaning

The monitor can be equipped with a panel protector. This secures the screen from scratches, damages and liquids and alleviates cleaning and disinfection of the front surface.

Customer Assurance with Medical Standards

The monitor meets the high requirements of itnernational medical safety and EMC standards.
