LG 32HR734S-W: 31.5" 4K Mini-LED Surgical Monitor
Authorized LG medical imaging equipment supplier. The LG 32HR734S-W is purpose-built surgical display technology for high-acuity operating room environments. It solves three persistent problems in clinical imaging. Edge-lit backlights wash out contrast in bright surgical suites, operating room ceiling glare obscures fine tissue detail, and multi-cable 4K signal distribution is complex. The 32HR734S-W replaces those compromises with an integrated, clinically validated display platform.
The core medical imaging technology is a full-array Mini-LED backlight with 1,500 independent local dimming zones, 2,000 cd/m² peak brightness, and a DCI-P3 98 percent wide color gamut, the image fidelity that modern diagnostic imaging demands. A single 12G-SDI cable transports native 4K at 60 frames per second. The built-in Clone Screen mirrors the display to a second monitor with no splitter and no added latency, which makes the 32HR734S-W a complete operating room imaging solution for surgical suites, cath labs, and EP labs alike.

Mini-LED Precision, Optical Bonding, and Clone Screen
Three surgical display technologies set the 32HR734S-W apart from standard operating room monitors. Each addresses a specific failure point in traditional hospital imaging displays. Full technical data is in the expandable sections below.
Panel: 31.5 inch IPS, 3840 by 2160 4K UHD, 16:9
Backlight: full-array Mini-LED with 1,500 independent local dimming zones
Brightness, typical: 800 cd/m²

DICOM: Part 14 grayscale, stabilized at 500 cd/m²
Hardware Calibration: LG Calibration Studio
Response Time: 5 ms gray to gray at faster
Viewing Angle: 178° horizontal and 178° vertical
Optical Bonding: full-area bonding fills the air gap between the LCD and the protective glass with optical resin, which eliminates internal reflections that are critical for accurate surgical visualization in brightly lit operating rooms
Anti-Reflection: reduces ambient light reflections from operating room ceiling fixtures
Anti-Glare: diffuses specular reflections from surgical lights
Anti-Fingerprint: resists smudges and allows cleaning with operating room grade disinfectants
How the 32HR734S-W compares against a standard surgical monitor:
Clone Screen outputs a latency-free copy of the active display to any HDMI secondary monitor, with no external splitter required, and it works even when picture in picture or picture by picture modes are active. From cath lab interventional procedures to open surgery, the entire care team views the identical live feed, which improves collaboration and real-time clinical decisions without adding cabling complexity to your imaging equipment setup.

Clinical Applications
Deployed across the full spectrum of hospital imaging environments, wherever display fidelity and system reliability directly affect procedural outcomes and patient safety.
Full-array Mini-LED contrast and single-cable 12G-SDI integrate directly with laparoscopic tower systems and operating room AV infrastructure without additional distribution hardware.
Peak brightness of 2,000 cd/m² and DCI-P3 98 percent color reveal subtle mucosal detail that standard operating room imaging equipment can miss under bright procedural lighting.
Automatic failover input switching and an IP45-rated front panel keep cath lab equipment running uninterrupted during time-critical interventional cardiology procedures.
Clone Screen mirrors to the technologist console for a true shared imaging view, with no splitter, no signal delay, and no additional hardware between the procedural and control positions.
DICOM Part 14 calibration and native 4K resolution deliver precise fluoroscopic and intraoperative reference imaging for procedures where spatial accuracy matters most.
Clone Screen feeds a fully identical second display for observers, residents, and AV recording systems, without modifying the primary operating room workflow.
12G-SDI, Clone Screen, and Multi-View
A complete 4K surgical AV integration platform engineered to slot into existing hospital imaging infrastructure, including PACS radiology systems, laparoscopic towers, cath lab AV routing, and multi-room imaging networks. The expanded details on inputs, outputs, multi-view modes, failover logic, and mounting are in the expandable sections below.
HDMI x1: connects cameras, a PC, or image management systems.
DisplayPort x1: supports high frame rate 4K sources.
12G and 3G-SDI x4: 12G-SDI carries native 4K at 60 frames per second over one coaxial cable, while 3G-SDI requires four cables for the same result, and SDI routes directly from C-arm and fluoroscopy sources into PACS radiology workflows.
DVI-D x1: provides legacy system compatibility.
USB 3.0: supports firmware updates and peripherals.
Clone Screen, HDMI output: mirrors the complete display to a secondary monitor with no external splitter and no added latency, and it works even with picture in picture or picture by picture active.
SDI loop-through, 12G and 3G, four channels: passes each SDI input directly to recording systems, a PACS archive, or additional monitors without signal loss.
4PBP: displays up to four independent sources side by side, such as a laparoscopic camera, fluoroscopy, a vitals overlay, and a PACS reference at the same time.
PIP: overlays a secondary source in a resizable picture in picture window.
Mirror Mode: flips the display horizontally for boom arm orientations.
Rotation Mode: rotates the output 180 degrees for non-standard mounting.
The 32HR734S-W monitors signal integrity on the active input and automatically switches to a backup source across HDMI, SDI, DVI, or DisplayPort without manual intervention. For 12G-SDI in particular, the system switches from the primary input to the next available input if a signal loss is detected, which keeps the video output consistent during surgical procedures.
IP45, front: dust tight and protected against water jets, and compatible with operating room grade disinfectants.
IP32, except the front: protected against vertically falling water drops and solid particle ingress.
IK06: withstands 1 joule of impact energy.
Weight: 9.7 kilograms, which is 21.3 pounds.
VESA: 200 by 100 millimeters and 100 by 100 millimeters are supported.
