32" 4K 3D Monitor with Polarizer
The 32" 4K 3D Monitor with Polarizer was developed for medical applications that require precise stereoscopic image visualization. The solution combines 4K resolution with glasses-based 3D and is designed for surgical environments in which depth perception, image detail, and high-quality visualization are critical.

Glasses-Based 3D: Stereoscopic Methods
Glasses-based 3D monitors use passive polarization and require surgeons or other users to wear lightweight polarized glasses. This technology provides high-quality stereoscopic depth perception and is currently one of the most widely used solutions in surgical environments due to its proven reliability and cost efficiency.
Side by Side (SBS)
How it works:
The left and right eye images are displayed next to each other horizontally. Each image is scaled to half of the horizontal resolution.
Pros:
Simple signal processing, widely supported.
Cons:
Reduced horizontal resolution per eye.
Top/Bottom (Over/Under)
How it works:
The left and right eye images are placed one above the other. Each image is scaled to half of the vertical resolution.
Pros:
Lower bandwidth requirements for transmission.
Cons:
Reduced vertical resolution per eye.
Line by Line (Interleaved)
How it works:
The left and right eye images are split line by line. Example: Odd lines = left eye, even lines = right eye.
Pros:
No heavy scaling needed, efficient use of pixels.
Cons:
Potential image artifacts depending on the panel and glasses used.
