Product Descriptions
Multiple Inputs
Each screen is equipped with 2×12G-SDI inputs, 1×12G-SDI output, and 1× HDMI input, supporting up to three 4K signals simultaneously, allowing customers to quickly switch between SDI-1/SDI-2/HDMI signals with ease, making it highly flexible to various scenarios.
Full-Screen Waveform
One screen ensures monitoring, while another focuses on Full-Screen Waveform(as for 4 screens, 1&2 as a set, 3&4 as a set). Five waveform available: Waveform Monitor, Vector Scope, Histogram, Audio Phase, or Audio Meter.
Factory-Calibrated for Consistent Color
Every Konvision monitor undergoes rigorous color calibration before shipping. With proprietary 3D LUT color calibration technology based on tetrahedral interpolation algorithms, paired with industry-leading calibration software (Calman/ColourSpace) and professional-grade probes (e.g., colorimeter K10-A, luminance meter CR300), we ensure precise and consistent color accuracy across all units and screens.
High Dynamic Range
Konvision's HDR simulation technology restores and simulates HDR signals, accurately presenting rich details in both highlights and shadows. While displaying HDR content, it supports calculating and displaying the percentage of areas with luminance above 203 nits.
Custom LUT Import
Easily import and store 3D LUTs via USB. Once loaded, different LUT effects can be applied across multiple screens for side-by-side comparisons, no need for screen switching.

Multiple Gamma and EOTF Curve Conversion
Supports Gamma 2.0, 2.2, 2.4, and 2.6, along with a variety of EOTF curves that comply with broadcast and digital cinema standards.
Remote Control
Compatible with TSL 3.1/4.0/5.0 protocols and supports GPI-based remote control for a wide range of functions, including signal input selection, blue-only mode, marker, Tally control, and aspect ratio.
Three-Color TALLY Light
The TALLY light uses red, green, and yellow indicators for clear and intuitive signal status display. Control or customize the TALLY light through the RS422 interface using TSL or GPI protocols.
User-Friendly Operation
Features ergonomic button layouts and shortcut keys for seamless operation. The multifunctional knob allows precise adjustment of brightness, contrast, volume, and system menu settings.
