Monitor - Endo 3D 4K - Visibility EX3141

4K 3D Surgical Display with High Visibility

This monitor faithfully reproduces stereoscopic images in 4K UHD resolution (3840 x 2160) at a high brightness of up to 450 cd/m², achieving both detail and depth for endoscopy and microsurgery.
Monitor - Endo - S.R.S.C

Enhanced Sharpness

EIZO's proprietary image sharpening technology Smart Resolution with Sparse Coding (S.R.S.C.) allows full HD images shot by conventional endoscopy and surgical cameras to be displayed in high definition 4K resolution without lag.
Monitor - Endo 4K 3D - Large Images EX3141-3D

View Large Images in Full HD

When inputting a 4K UHD signal, you can zoom in on a specific area of the screen and display it with a resolution equal to or higher than full HD.
Monitor - Endo 3D 4K - Color Gamut EX3141-3D

Sharp Color Reproduction with Wide Color Gamut

Not only does the monitor faithfully display the sRGB color gamut, but it also reproduces images emulating the 4K video color standard BT.2020. This ensures vivid reds and yellow-greens captured with BT.2020-supported cameras are displayed more accurately.
Monitor - Endo 4K - HDR

HDR Compatibility

HDR (High Dynamic Range) is a range that approximates the human perception of color and light as content is shown on a display device. The monitor is equipped with the perceptual quantization (PQ) curve and hybrid log-gamma (HLG) for supporting HDR. This ensures images from HDR-supported endoscope cameras are displayed without crushing blacks and more closely resemble the human visual system.
Monitor - Endo 3D 4K - Design EX3141-3D

Fully Flat Design

Operating rooms contain various medical devices that are arranged by the type of surgery being undertaken. In consideration of safety, EIZO's surgical monitors adopt rounded corners. Furthermore, the front is covered with a fully flat protective glass with IP45 for protection against foreign material and splashes (the whole monitor has an IP32 rating).
Monitor - Endo 3D 4K - Cable Cover EX3141-3D

Cable Cover for Safety and Hygiene

With the attached cable cover, cables can be stored neatly out of sight, increasing safety and hygiene.
Monitor - Endo - Improved Durability

High Durability

The monitor has protective glass with a hardness of 9H, making it resistant to impacts. Furthermore, the monitor is equipped with optical bonding, which removes the layer of air between the LCD panel and glass. This ensures foreign materials such as dust and moisture cannot damage the LCD panel.
Monitor - Endo - Reduced Reflections

Reduced Reflections

Reflections on the screen of LCD monitors are caused when external light hits the screen and reflects off of the protective glass and layer of air at different refractive indices. Optical bonding removes the layer of air in order to lower the difference of refractive indices. This softens the reflections and produces a clear, highly visible image without affecting contrast.
Monitor - Endo - Condensation Prevention

Condensation Prevention

Optical bonding prevents condensation from forming between the LCD panel and protective glass. This allows the monitor to maintain high visibility in harsh environments.
Monitor - Endo 3D - 3D-Formats

Various 3D Signal Format Support

The monitor supports Side by Side, Line by Line, Top and Bottom, and Simulcast (SIMUL) 3D signal formats.

Monitor - Endo 3D - Rotation

3D-mode: 180 Degree Rotation

Regardless of the orientation of the endoscopic camera, you can display the image in a direction that is easy to see.

Monitor - Endo 3D - Parallax

3D-mode: Parallax Adjustment

With the parallax adjustment function, you can adjust 3D images both vertically and horizontally so that it displays a natural sense of depth.

Monitor - Endo 3D - Independent Adjustment

2D-Mode: Adjust Screens Individually

When displaying two signal sources side by side on the same screen, each image's display mode (gamma 1.8 - 2.6 or DICOM Preset Mode) can be adjusted independently of the other image. This is useful for viewing two different modalities simultaneously under the correct display conditions (e.g. endoscope, CT, MRI). 

Monitor - Endo 3D - Rotation and Mirroring

2D-mode: 180 Degree Rotation and Mirroring

Regardless of the orientation of the surgical camera, you can rotate or mirror the screen by 180 degrees to achieve the perfect operating view.

Monitor - Endo 4K - Cable Management EX3141-3D

Easy Cable Management

With 12G-SDI (BNC), and DisplayPort 1.2 or HDMI, 4K UHD images are displayed at 60 frames per second with a single cable over various modalities.

Also, the small AC adapter size aids in easy cable management. With the 12G-SDI (BNC) terminal, stable transmission is possible even over long distances of 30 meters.

Monitor - Endo 4K - Safe Connection

Safe and Stable Video Connection

Typically HDMI cables cannot be locked into a terminal but this monitor contains a specialized locking mechanism on its side specifically for HDMI. This ensures all cables can be locked onto the monitor for consistent and stable connection.

Rest Assured with Medical Qualifications

In order to realize safe and reliable monitors that can be used with confidence at any medical institution, EIZO acquires various medical standards and safety/EMC standards.
