MS323PA 4K UHD Mini-LED Surgical Monitor FAQ

How does Mini-LED local dimming benefit surgical imaging on MS323PA?

Mini-LED local dimming improves contrast control and luminance uniformity, helping subtle edges and depth cues stand out in endoscopic and laparoscopic video. In practice, this supports clearer differentiation of fine structures under challenging lighting and reflective conditions in the OR.

When should we enable or adjust local dimming during procedures?

Local dimming is typically beneficial for high-contrast content and scenes with dark backgrounds. If your team notices blooming around bright instruments or overlays, you can reduce or disable local dimming to prioritize uniform luminance. The best setting depends on the camera output, overlays, and ambient OR lighting—many teams set a default profile and fine-tune for specific specialties.

What connectivity makes MS323PA easy to integrate with existing OR systems?

MS323PA supports multiple input options including HDMI 2.0 ×2, DP 1.2 ×2, DVI ×1, and professional SDI (3G ×4, 12G ×1). This flexibility helps match common camera control units, routing/switching devices, and OR integration platforms without needing unnecessary converters.

Can we distribute the signal to another monitor or recorder?

Yes. MS323PA provides video outputs (HDMI ×1, DVI ×1, SDI ×1) that can be used for downstream routing, recording, teaching displays, or secondary viewing—depending on your system architecture and the format requirements of connected devices.

Does MS323PA support multi-source viewing for team collaboration?

MS323PA supports multi-view modes such as PIP, PBP, and quad-view. Typical OR use cases include camera feed + ultrasound, camera feed + patient data, or two camera sources side-by-side—helpful for coordination, teaching, and complex minimally invasive workflows.

How does optical bonding help in bright operating rooms?

Optical bonding reduces internal reflections and improves perceived contrast, helping maintain visibility under strong OR lighting. It also supports a flatter front surface that is easier to wipe clean, which is important for routine disinfection and daily OR turnover.

What color and gamma options matter most for clinical use?

MS323PA supports BT.2020 wide color performance for consistent color rendering, along with multiple gamma options (including DICOM and Linear) to suit different imaging sources and preferences. Many teams standardize a color/gamma preset per department to keep image appearance consistent across rooms and shifts.

Is the MS323PA suitable for low-latency endoscopy and laparoscopy?

For real-time procedures, stable signal handling and minimal processing are critical. Using direct digital inputs (SDI/DP/HDMI) and matching the monitor settings to the camera output helps maintain smooth motion and responsive viewing. If your workflow includes routing/switching, we recommend validating the full chain (camera → router → monitor) as part of OR commissioning.

What installation options are available for different rooms and carts?

MS323PA supports VESA 100×100 mounting, enabling boom-mounted, wall-mounted, and cart-mounted installations. When planning installation, consider viewing distance, cable routing, and line-of-sight for the full team—especially for teaching rooms or multi-user minimally invasive suites.

What power and included accessories should procurement plan for?

MS323PA uses DC 24V power and is supplied with essential accessories such as power adapter/cables and common signal cables (including SDI, DP, and HDMI). For streamlined deployment, many hospitals standardize spare cables and verify outlet/UPS compatibility for carts and booms during installation.
