HKC RAY-27 Naked-Eye 3D Monitor Launches With 120Hz 2K Display

Naked-eye 3D monitors have struggled to balance depth perception with visual comfort, but HKC is introducing a new approach with the RAY-27. This device aims to solve the common issue of eye strain by using directional light field technology to project images directly to the viewer's eyes. The monitor supports simultaneous 2D and 3D operation at the same 2560×1440 resolution, which means users can switch modes without losing clarity. This capability matters because it allows gamers and creators to use a single display for standard content and immersive 3D experiences without compromising pixel density.

Dual LCD panels synchronize light source for precise 3D alignment

The RAY-27 relies on a dual LCD panel setup that operates at a 120Hz refresh rate. HKC synchronizes the light source with these high-frequency panels to maintain precise image alignment. The system also incorporates pupil tracking to adjust the light field based on the user's position. This hardware configuration is designed to reduce the physical discomfort often associated with 3D displays. The monitor is scheduled for display at the 2026 DIC exhibition, marking its first public appearance.

Specifications

• Resolution: 2560×1440
• Refresh Rate: 120Hz
• Technology: Directional light field 3D
• Crosstalk: Center ≤3%, Global ≤5%

HKC specifies a viewing angle of plus or minus 20 degrees for optimal 3D performance. The recommended viewing distance sits between 60 and 100 centimeters from the screen. To minimize dizziness, the company targets a crosstalk rate of 3% or less at the center of the image. Global crosstalk remains under 5% across the entire display area. These technical constraints define the specific setup required for users to experience the 3D effect effectively.

The RAY-27 represents a shift toward practical naked-eye 3D by prioritizing low crosstalk and fixed resolution parity. Users interested in 3D gaming or visualization will need to maintain a strict viewing distance to utilize the feature. The product demonstrates a focus on technical stability rather than flexible viewing zones. We will see how this specific hardware configuration performs in real-world usage once the exhibition concludes.
