Monitor - Endo 4K - UHD Display

Display Surgical Images in 4K UHD High Resolution

The monitor has a resolution of 3840 x 2160 pixels, which is four times the size of a full HD monitor. 4K UHD endoscope and microscope images can be reproduced in high definition. Easily see fine details that are otherwise difficult to distinguish on full HD monitors.

Article: Three Reasons to Use 4K Endoscopy and Surgical Monitors

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 - Zoom

View Large Images in Full HD

When inputting 4K UHD signal, even if an area of the screen is magnified using the zoom function, it is possible to display the area with a resolution equal to or higher than full HD.

Monitor - Endo 4K - Color Gamut

Sharp Color Reproduction with Wide Color Gamut

Not only does the EX3140 faithfully display the sRGB color gamut, but it can also produce images emulating the 4K video color standard BT.2020. It accurately displays BT.2020-compatible camera images, increasing the range of yellowish-green to red.

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 4K - Design

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 and the monitor has a protection rating against foreign material and splashes of IP45 on the front and IP32 in entirety.

Monitor - Endo 4K - Cable Cover

Cable Cover for Safety and Hygiene

With the attached cable cover, cables can be stored neatly out of sight, increasing safety and hygiene in the operating room.

Monitor - Endo 4K - Protective Glass

Protective Glass

The monitor is covered with protective glass which helps guard the LCD screen from shock and dirt. The glass has a hardness of more than 9H, making it difficult to scratch, even if it accidentally bumps into walls when being moved.

Monitor - Endo 4K - one Cable

4K UHD Connection with One Cable

The 4K UHD video connection interface is equipped with one DisplayPort 1.2 and Quad Link 3G-SDI (BNC). Using the DisplayPort 1.2 terminal, 4K UHD image can be displayed at 60 frames per second with a single cable. Furthermore, the locking mechanism of a DisplayPort cable means that it cannot be accidentally unplugged, allowing for a consistent and stable connection. With the 3G-SDI (BNC) terminal, stable transmission is possible even over long distances of more than 30 m.

Preset Functions for Easy Switching

Various setting such as the input terminal selection, brightness, grayscale tones, color gamut, etc. can be stored in the monitor as preset functions. These settings can be named according to the operator's preference by easy operation of the OSD (On Screen Display) button.

Monitor - Endo 4K - Blickwinkel

Comfortably View from Any Angle

The EX3140 has a horizontal and vertical viewing angle of 178 degrees so images can be viewed from various directions with minimal changes in contrast.

Monitor - Endo 4K - Rotate and Mirror

180° Rotation and Mirroring

Regardless of the orientation of the surgical camera, you can rotate the displayed image by 180 degrees or mirror to find the perfect operating view. This is suitable for matching the image with the line of site of surrounding assistants and surgeons, improving convenience in the operating room.

Monitor - Endo 4K - Multiple Signals

View Multiple Signals on One Screen

Two separate signal sources can be viewed simultaneously on one monitor screen side by side using the PoP (Picture Out Picture) function. This is useful when several images need to be viewed at once, such as multiple modalities.

Monitor - Endo 4K - Adjust Screens

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 without interfering with the other image. This is perfect for multi-modality use, where endoscope, CT and MRI images can be accurately displayed on the same monitor.

Monitor - Endo 4K - Independent Rotation&Mirroring

Independent Rotation and Mirroring

When displaying two signals at the same time, each display can be rotated 180 degrees or mirrored independently from the other.

Monitor - Endo 4K - Vesa

Standard VESA Mounting for Convenient Installation

The monitor supports VESA mounting standards for installing in various locations such as from ceiling arms, wall hangings, endoscopic carts, and desktops. An optional stand is available for desktop installation.

Customer Assurance with Medical Standards

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