55" 4K IPS Surgical Display
DB55SF
The DB55SF is a 55-inch 4K IPS surgical display for room-scale viewing from the field, the circulating position, and anesthesia. The wide 178-degree IPS panel holds color and contrast across the room, and HDR10 support adds depth to live video. A 12G-SDI interface carries 4K over a single coaxial run for clean, low-latency routing.

Room-Scale 4K for the Whole Team
The DB55SF puts a large, calibrated 4K image where everyone in the room can see it. It is built for team viewing, stable signal handling, and clean integration on booms and walls.
Large 4K IPS Visibility
Clear From Every Position
The 55-inch IPS panel shows native 4K detail with a 178-degree viewing angle, so the picture stays consistent across the room. HDR10 support deepens contrast in live surgical video.
- 3840 × 2160 4K Resolution
- IPS Panel, 178° / 178° Viewing
- HDR10 Support
- 680 cd/m² Typical Brightness
- 10-Bit Color (1.07 Billion)
Multi-Source and Failover
Many Signals, No Blank Screen
The display shows up to four sources at once with PBP and PIP. A failover input switch moves to a backup source if the main signal drops, then restores it when the signal returns. Mirror and rotation modes align the image to the camera.
- Up to 4 PBP and PIP
- Automatic Failover Input Switch
- Mirror and Rotation Modes
- Black Stabilizer and Uniformity
12G-SDI and Broad Connectivity
4K Routing Made Simple
Four 12G-SDI inputs and outputs plus an SFP input handle 4K over long coaxial runs without latency. HDMI 2.0, DisplayPort 1.2, and DVI-D round out source support, with RS-232 and an equipotential pin for room integration.

FAQs
What is a 55" 4K surgical display used for?
It is a large-format display for whole-room viewing, so the field, circulating, and anesthesia staff can all read the same 4K image.
How does the automated DICOM calibration work?
An embedded front sensor measures the screen and calibrates it to the DICOM 3.14 grayscale standard. CFS Calibration Suite then tracks conformance and produces compliance reports. A rear sensor adjusts the backlight to hold brightness steady over time.
What happens if the main video source drops?
The failover input switch moves to a backup source automatically, then restores the main source when its signal returns.
How does it handle 4K cabling over distance?
Four 12G-SDI channels plus an SFP input carry 4K over long coaxial or fiber runs without latency.
Is it protected against fluids and tampering?
The front is rated IP45 against splashes, and the unit is vandal-proof with a direct-bonded glass face for easy cleaning.
How is it mounted?
It supports 200 × 200 mm and 300 × 300 mm VESA patterns for heavy-duty wall mounts and booms. Confirm load ratings with your mount supplier.
The DB55SF is configured, tested, and supported in the USA and backed by a 3-year warranty.
