Before Using the Monitor Checking the Environments of the Installation Location of the Monitor The apparent color reproduction on the monitor is greatly affected by ambient light or glare. This section introduces the ideal conditions of use for standard-definition (SD) CRT monitors for studio use meeting standards set by SMPTE. Illumination The ideal illumination conditions for a monitor are as follows: – indirect lighting – illumination with a color temperature near that of the reference white (D65 or D93, depending on the standard in your region/country) – Maximum light around the monitor: 12 cd/m 2 (10% illumination of 120 cd/m2 white [100 IRE] on a monitor) – 30 to 40 lux reaching the operator – 20 to 100 lux in client area or script reading area Notes on the illumination environments for LCD and CRT monitors The illumination environments greatly influence the reproduction of black, or the contrast, on LCD and CRT monitors. Under a bright illumination, for example, in an office room which has about 500 to 2000 lux, the LCD monitor provides a higher contrast than the CRT monitor. Under a lower illumination, for example, in a studio, the CRT monitor has a higher quality than the LCD monitor. The LCD device controls the brightness by moving LCD molecules with the backlight always lit. For this reason, in a dark place, an LCD monitor screen shows very dim light leaks from the black image. In a bright place, however, the LCD monitor is able to provide a high contrast thanks to its advantage of smaller light reflection. On the other hand, the CRT monitor can cut off the black signal input and reproduce black even in a dark place. However, its contrast becomes lower in a bright place, as reflected outdoor light degrades the reproduction of black. Viewing Distance The ideal viewing distance is 4 to 6 times the vertical height of the monitor screen area. Note on viewing distance for high-definition (HD) signals When a high-definition (HD) signal is displayed on the monitor, the ideal viewing distance is 3 times the vertical height of the monitor screen area. Installation Location The ideal installation location is 60 to 120 cm (2 to 6 feet) away from the wall at the back of the monitor. 6 The Basics of Monitor Technology Wall Color A neutral tint, especially neutral gray, is ideal for the wall color of the room where you install the monitor. The neutral gray area of more than 8 times the monitor screen area is needed. Viewing Angle The ideal viewing angle is within 5 degrees from the center of the monitor screen when the operator views the entire monitor screen. Keep the viewing angle within 15 degrees from the center of the monitor screen.
