When colour accuracy is is of the utmost importance, the ColourEdge CG2730 27inch 16:9 IPS Monitor from EIZO has the tools needed for colour accuracy and consistency. This 27inch widescreen display features a 2560 x 1440 WQHD resolution complete with 99% coverage of the Adobe RGB colour space and 98% coverage of the DCI-P3 colour range. In addition to enhanced colour accuracy, this IPS (In-Plane Switching) panel supports a 1500:1 static contrast ratio, 350 cd/mÂ² brightness rating, a 16-bit look-up-table, 48-bit (3 x 16-bit) with approximately 278 trillion hues, and 178° horizontal and vertical viewing angles.
Setup of the ColourEdge CG2730 monitor is simple as it comes equipped with DisplayPort, DVI-D, and HDMI inputs. Once connected, the display can be calibrated, to ensure improved colour accuracy using the built-in colour measurement device along the Digital Uniformity Equaliser (DUE), for true colour representation from the centre of the display all the way to the edges. To back up the colour calibration capabilities of this display, EIZO has utilised their own microchip designed for precise and consistent colour quality. This EIZO monitor also comes with a copy of ColourNavigator software and light protection shields.
Enhanced Image Quality
The CG2730 features clear graphics and structures as well as sharp text contours. Its IPS LCD panel offers enhanced contrast and hues that are independent of the viewing angle. The back lighting is achieved by using improved energy-saving LED technology.
EIZO Microchip for Enhanced Colour Reproduction
The CG2730 is equipped with a high-quality microchip (ASIC, or Application Specific Integrated Circuit) that EIZO developed specifically for the special requirements involved in work demanding high colour accuracy. The EIZO ASIC ensures precise, consistent, and lasting colour display thanks to its special algorithms.
Compact, Space Saving Design
The sophisticated LCD panel has a very narrow border and is designed for a compact housing. Power supply and signal interfaces are unobtrusively integrated into the unit.
The gamut of the CG2730 includes up to 99.9% of the Adobe RGB colours. For example, it covers colours in offset printing at 100%. For this reason, the screen visibly shows which saturation has been achieved with cyan and yellow tones.
Thanks to its 16-bit look-up table, the CG2730 can resolve image signals with an accuracy of 1/65 thousandths. Colour nuances and image structure are not lost, particularly in the case of dark hues. This reliable and precise reproduction reduces calibration steps, saving valuable production time.
Consistent Hue Curve and Colour
The brightness level of LCDs varies from module to module in relation to the image signal and the addition of red, green, and blue. This can only be recorded and corrected using special measurement devices. For this reason, EIZO configures each CG2730 at the factory with its colours and hue curve. This ensures that a consistent colour temperature is attained throughout the entire grayscale range. The result: Colour reproduction is balanced, precise, and reliable for the CG2730.
Integrated Measurement Device
The CG2730 achieves maximum colour accuracy thanks to its integrated measurement device. This is automatically positioned for calibration and is concealed in the bezel until the next measurement. EIZO optimally calibrates each CG2730 and its integrated measurement device. This integrated solution eliminates production spreads, as can occur with external measurement devices. The fact that the measurement is carried out at the upper edge of the screen makes no difference, because the CG2730 is equipped with DUE and the sensor is correlated with the centre of the screen.
Digital Uniformity Equaliser (DUE)
The DUE in the CG2730 ensures colour purity and even brightness distribution across the entire display surface. A chip automatically adjusts for irregularities. While conventional LCDs are optimised at best for homogeneity of a white surface, every hue looks the same across the entire screen with EIZO. The DUE ensures precisely matching colours from the centre right to the outermost edge of the screen, where the integrated sensor extends to measure and carries out the adjustment for the entire surface and all tonal values.
The ColourNavigator software (included in the delivery of the CG2730) has direct access to the monitor's lookup-table during calibration. This enables the user to set colour temperature, brightness, blackness, and hue curve to suit their requirements. Calibration is based on the default set during production and is therefore unique in terms of precision and speed.
The CG2730 calibrates itself without requiring any user input. The computer does not even have to be turned on. Once programmed, the CG2730 starts the adjustment at night, during lunch, or at any other defined time. Programming takes place conveniently via the ColourNavigator or the on-screen menu.
Colour Drift Correction
Temperature deviations can lead to imprecise colour reproduction. Colour deviations of more than 2 Î”E often arise, especially when the room temperature fluctuates. The CG2730 has an internal thermometer to eliminate these inaccuracies. It controls and reduces the unwanted colour drift fully automatically.
Balanced brightness is crucial for brilliant colour reproduction. Traditional LCD monitors need one to two hours to even out their brightness. However, even then, they are still sensitive to temperature deviations. The patented electronics of the CG2730 therefore regulate the backlight. They ensure constant brightness, regardless of the operating times and temperature.
Dark tones on LCD monitors in poorly lit rooms can appear blurry or too light depending on the viewing angle. True Black ensures a high contrast ratio at all times. This means that dark tones do not lose their depth on the CG2730.
DisplayPort, HDMI, and DVI-D ports allow up to three computers to be connected at the same time. Users can switch between the interfaces automatically or manually. HDMI signals from HD cameras can be viewed directly on the CG2730 using the HDMI and DisplayPort ports.
An integrated USB hub (Ver. 3.0) is provided for the connection of peripheral devices. For example, a keyboard and mouse can be connected to the monitor. The CG2730 has two upstream ports, enabling devices connected to the monitor to be used alternately with two computers. One of the three downstream ports can be used as a high-speed battery charging port.
The monitor offers the standard resolutions and image refresh rates for video production. HDMI signals (YUV and RGB) are supported with refresh rates of 60, 50, 30, 25, and 24 Hz. The monitor also features I/P conversion. The CG2730 can be conveniently used in video editing and animation systems, too.
10-bit Colour Depth
The CG2730 has a DisplayPort and an HDMI port, in addition to the DVI interface. The ports have a 10-bit colour resolution in combination with the frame rate control (FRC). The monitor can therefore display even the smallest of tonal gradations with a billion colours. However, you need to have the corresponding application software and graphics board that provide 10- bit support.
