In February 2021, EIZO accepted an Academy Sci-Tech Award (Technical Achievement) for the ColorEdge CG Series monitors with built-in calibration sensors. EIZO was the first manufacturer in the world to bring a self-calibrating color precision solution to market in 2010, and continues to commit itself to providing highly precise and sophisticated imaging solutions made with dedication and care. In September 2020, the ColorEdge PROMINENCE CG3146 HDR reference monitor received the 2020 Hollywood Professional Association (HPA) Award for Engineering Excellence.
As the first true HDR reference monitor in the world to be equipped with a built-in calibration sensor, it was recognized for its advanced technologies, putting it at the forefront of innovation in creative visual solutions.
ColorEdge monitors undergo rigorous quality control during production and are adjusted using professional spectrophotometers for consistency in measurement results. Sensors are placed directly over monitors and red (R), green (G), and blue (B) gamma values are measured from 0 – 255. The monitor’s 16- or 24-bit LUT is used to select 256 tones from trillions of colors to achieve the smoothest color gradations and images without deviated steps.
After a monitor has been fully calibrated for maximum precision, it still needs to be recalibrated at regular intervals to maintain accuracy over time. To do so, a sensor is used to measure the state of the monitor and adjust the values from the reading to match a predefined standard via dedicated softwares. As software calibration can provide inconsistent results and losses in gradation steps, ColorEdge monitors use hardware calibration, which controls the hardware of the monitor directly by utilizing its LUT (look-up-table) to offer higher precision and better gradation characteristics. This is the preferred method for color-critical applications.
Using EIZO’s expertise in color science, the ColorEdge CG Series built-in sensor is calibrated using high-end spectrophotometers to achieve precision. With EIZO’s patented DUE technology, ColorEdge monitors achieve high uniformity across the screen so that no matter where the sensor is placed, precise measurements are taken. The built-in sensor is positioned in the top bezel to minimize imposition on the creator’s visual line of sight. EIZO’s engineers conduct extensive testing of the sensor’s mechanical components, ensuring the mechanism that moves the sensor into place operates correctly throughout the life of the monitor. The sensor is carefully positioned at a nearly imperceptible distance from the screen’s surface so as not to allow ambient lighting to interfere with readings. Operators can rest assured the sensor will measure accurately.
EIZO’s modern built-in sensor technology supports accurate measurability of HDR values. This allows for accurate readings of extremely high (1000 cd/m2) and low brightness levels across the screen – typically a challenge due to high and low brightness levels’ susceptibility to saturation and noise respectively. The built-in sensor’s optical design and measuring circuit were developed to combat this and ensure consistent screen characteristics under the new HDR standards for content creation. This technology is implemented in the ColorEdge PROMINENCE CG3146 – the world’s first true HDR reference monitor with a built-in calibration sensor.
