LINCOLNSHIRE, Ill., April 30, 2025 – Medical imaging technology leader LG Electronics USA, is introducing a new 31.5-inch, 4K (3840 x 2160 resolution) surgical monitor with advanced Mini LED display technology. This monitor (model 32HR734S) features enhanced color reproduction and local dimming zones to produce clearer, detailed images and precise brightness control.

Designed as an advanced color video display for various compatible medical imaging systems, the new surgical monitor enables precise brightness control. It also provides an ultra-wide color gamut, optimizing image clarity and color, making it an ideal choice for a variety of surgical applications, including laparoscopy and endoscopy. Its lightweight design (only 21.3 pounds) gives flexibility to the end-user for mounting on surgical arms and booms.

The display’s Mini LED backlight technology utilizes thousands of tiny LED diodes and provides excellent color consistency across the screen, with 98 percent coverage of the DCI-P3 color space. It has 1,500 local dimming zones, inherent to Mini LED technology, producing clear, detailed images and precise brightness control across the entire LED backlight. This enhances visual contrast by darkening the dark areas and brightening the light areas, significantly enhancing the dynamic contrast ratio up to 1,000,000:1 and reaching a peak brightness up to 2,000 cd/m2. The local dimming technique may also improve energy efficiency and screen life compared to traditional edge-lit backlight technologies.

“Our Mini LED technology produces outstanding images for surgeons, with local dimming zones increasing the brightness and the contrast ratio, along with an enhanced color spectrum, allowing for deeper, truer anatomical colors,” said Stephen K. Hu, LG Electronics USA’s head of medical displays. “Having recently received 510(k) clearance, this device is now available for surgeons to experience an immersive environment to focus entirely on the surgical procedure and operate precisely.”

In addition to its impressive visual performance, the 4K Mini LED surgical monitor is built for the demanding conditions of the operating room. Engineered for durability and reliability, it features high resistance to physical impact, as denoted by its IK06 rating, while its liquid ingress ratings ensure optimal splash protection in surgical environments. It employs Optical Bonding technology, seamlessly integrating the backlight, module, and glass without any air gaps, along with Anti-Glare, Anti-Reflection and Anti-Fingerprint coatings on its front, significantly improving display readability by minimizing reflections and glare – ensuring that image clarity and color response are optimized even in brightly lit surgical environments.

The launch is also the first LG surgical monitor to incorporate the innovative Clone Screen feature. Clone Screen allows users to duplicate the image being displayed on the Mini LED on a second monitor (connected via HDMI), facilitating operational efficiency and communication within the surgical environment, especially in situations where multiple medical professionals need to view the same image.

For added versatility, the monitor supports both 4PBP (Picture-by-Picture) and PIP (Picture-in-Picture), allowing it to display input from up to four different sources simultaneously or overlay one input on another. These features enable medical professionals to monitor various critical information streams concurrently on a single screen, enhancing operational efficiency and decision-making. For example, medical staff can view a combination of laparoscopic and endoscopic images while monitoring vital signs. Additionally, Mirror Mode makes it possible to flip the on-screen image horizontally, while Rotation Mode can rotate the image 180 degrees to match the orientation of the surgical camera, allowing users to adjust the display for optimal viewing.

The monitor supports 12G-SDI, which enables long-distance transmission of 4K signals over a single coaxial cable, while the Failover Input Switch feature ensures uninterrupted video signal by automatically switching to an alternative video source if the primary input fails. This function is compatible across all interfaces, including HDMI, SDI, DVI, and DP, offering flexibility in setup and redundancy in signal sources. Particularly for 12G-SDI, the system can automatically switch from the primary input to the next available input if a signal loss is detected. This seamless transition between inputs minimizes disruptions and ensures consistent video output, essential for surgical applications where continuity of care and image clarity are critical.
