4K UHD LCD Monitor OEV321UH
The 4K UHD LCD Monitor is intended to provide 4K 2D color video displays of images from endoscopic camera systems and other compatible medical imaging systems. The 4K UHD LCD Monitor is a wide-screen, high-definition, medical grade monitor for real-time use during endoscopic procedures and is suitable for use in hospital operating rooms, surgical centers, clinics, doctors' offices and similar medical environments.
This monitor displays color video images that are output from medical imaging systems on the LCD (liquid crystal display) panel. Liquid crystal and color filters are laid on the front of the flat light source (backlight) of the LCD panel. The LCD panel displays images by controlling the aperture of the liquid crystal according to input signals.
This document describes a 510(k) premarket notification for the Olympus 4K UHD LCD Monitor (Model Number: OEV321UH). The purpose of this submission is to demonstrate substantial equivalence to a legally marketed predicate device, the Sony LMD-X310S LCD Monitor (K150377).

Study Proving Device Meets Acceptance Criteria:
The study proving the device meets the acceptance criteria is a technical and performance verification and validation testing program as outlined in the "Summary of Performance Testing" section of the 510(k) submission.
- Electrical Safety and Electromagnetic Compatibility (EMC): The device was confirmed to be in compliance with ANSI AAMI ES 60601-1:2005+A1:2012 (general requirements for basic safety and essential performance) and IEC60601-1-2:2014 (EMC requirements).
- Software Verification and Validation Testing: This was performed and documented in compliance with FDA guidance for software in medical devices and cybersecurity.
- Risk Analysis: A risk analysis was conducted in accordance with ISO 14971, which identified design verification tests and acceptance criteria.
- Human Factors Validation Testing: Performed in accordance with FDA Guidance, this assessed applicable adverse events and reviewed overall risk analysis to confirm no unacceptable user-related residual risk.
The submission states that the 4K UHD LCD Monitor OEV321UH "has been verified and validated to be equivalent in electrical performance for displaying images from endoscopic camera systems and other compatible medical imaging systems, when compared to the predicate." The differences in system parameters (dimensions, input/output, active screen size, resolution, luminance, gamma curve) were reviewed via a risk-based assessment, which "did not identify any new risks or significantly modified existing risks, or raise new or different questions with respect to safety and effectiveness."
This is a submission for a medical display monitor, not an AI or diagnostic algorithm, so many of the requested items (e.g., sample size for test set, ground truth experts, MRMC study, training set) typically associated with AI/algorithm efficacy studies are not applicable in the same way.
Below are the answers to the specific questions, with "N/A" where not applicable to this type of device and submission.
2. Sample size used for the test set and the data provenance
- Sample Size: N/A for a typical "test set" as defined for algorithm performance. The testing involved a single device (the Olympus 4K UHD LCD Monitor, Model OEV321UH) undergoing electrical safety, EMC, software, and performance verification tests.
- Data Provenance: N/A. The "data" here would be test results from specific technical standards and internal verification protocols, not patient data from a specific country or retrospective/prospective study.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- N/A. Ground truth, in the context of image interpretation by experts, is not relevant for a display monitor's technical performance verification. The "ground truth" here is compliance with established engineering and safety standards.
4. Adjudication method for the test set
- N/A. Adjudication methods (like 2+1 or 3+1) are used to resolve disagreements among human readers on clinical cases. This is not applicable to technical compliance testing of a monitor.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No. An MRMC study is not relevant for a medical display monitor as it's not an AI-powered diagnostic tool. The device is a passive display for human interpretation.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- While the monitor operates standalone (i.e., it doesn't require a human to perform its basic function of displaying an image), this question typically refers to the standalone performance of an AI algorithm. In that context, no such study was done as this is not an AI algorithm. The device's standalone performance was demonstrated through technical verification and validation against engineering specifications.
7. The type of ground truth used
- The "ground truth" for this device's performance is adherence to established international and national electrical safety, electromagnetic compatibility, software validation, and risk management standards (e.g., ANSI AAMI ES 60601-1, IEC 60601-1-2, ISO 14971, and FDA guidance on software and human factors). It's essentially engineering and regulatory compliance standards.
8. The sample size for the training set
- N/A. This is not an AI algorithm, so there is no "training set."
9. How the ground truth for the training set was established
- N/A. Since there is no training set, this question is not applicable.
