LG Unveils 4K Mini LED Surgical Monitor for Enhanced Image Clarity in OR

What You Should Know: 

– LG Electronics USA, a leader in medical imaging technology, today introduced its latest innovation for the operating room: a new 31.5-inch, 4K surgical monitor (model 32HR734S) featuring advanced Mini LED display technology. 

– Designed to provide surgeons with clearer, more detailed images and precise brightness control, the monitor recently received 510(k) clearance and is now available.

Advanced Imaging with Mini LED Technology

The new monitor leverages Mini LED backlighting, utilizing thousands of tiny LED diodes across 1,500 local dimming zones. This technology enables exceptional brightness control and significantly enhances visual contrast, achieving a dynamic contrast ratio of up to 1,000,000:1 and a peak brightness of up to 2,000 cd/m2. The result is clearer, more detailed images where dark areas appear darker and bright areas brighter.

Furthermore, the display boasts an ultra-wide color gamut, covering 98 percent of the DCI-P3 color space, ensuring excellent color consistency and reproduction across the 4K (3840 x 2160) screen. This optimization of image clarity and color makes it ideal for demanding surgical applications like laparoscopy and endoscopy.

“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. “This device is now available for surgeons to experience an immersive environment to focus entirely on the surgical procedure and operate precisely.”

Designed for the Operating Room Environment

Understanding the demands of the surgical suite, LG engineered the 32HR734S for durability and usability. It carries an IK06 rating for high resistance to physical impact and features liquid ingress protection against splashes. The monitor also incorporates Optical Bonding technology, which integrates the display layers without air gaps, combined with Anti-Glare, Anti-Reflection, and Anti-Fingerprint coatings. These features minimize reflections and ensure optimal image clarity even in brightly lit operating rooms. Its relatively lightweight design (21.3 pounds) also offers flexibility for mounting on surgical arms and booms.

Versatile Display Modes and Connectivity

Enhancing operational efficiency and communication, this is the first LG surgical monitor to feature Clone Screen, allowing the primary display image to be duplicated onto a second monitor via HDMI. It also supports 4PBP (Picture-by-Picture) and PIP (Picture-in-Picture) modes, enabling the simultaneous display of up to four input sources or the overlaying of one source onto another. This allows medical teams to monitor various data streams, such as endoscopic images alongside vital signs, on a single screen. Additional viewing flexibility is provided by Mirror Mode (horizontal flip) and Rotation Mode (180-degree rotation) to match camera orientation.

For reliable signal transmission, the monitor supports 12G-SDI, enabling 4K signals to travel long distances over a single coaxial cable. Crucially, it includes a Failover Input Switch feature. If the primary video signal (across HDMI, SDI, DVI, or DP interfaces) is lost, the monitor automatically switches to an alternative input, ensuring uninterrupted video crucial for surgical procedures.
