Скачка напряжения не было, а монитор плоский, марки AVALON, 19´´, TCO`03, а более подробные его показатели я скопировала с сайта производителя (если надо..., для меня это все равно филькина грамота)
This is a summary of the requirements for flat panel displays in TCO'03 Displays.
For more detailed information see the labeling standard.
Visual ergonomics
Resolution
The display shall have at least 30 pixels/degree.
Brightness
Brightness must not be too low. It must be at least 150 cd/m2.
There must be even brightness over the entire display. Brightness may only differ by a maximum ratio of 1.5 to 1.
Brightness must be even over the entire display, even when viewed at an angle. Brightness may only differ by a maximum ratio of 1.7 to 1 for a 30-degree angle in the horizontal. The same requirement applies to rotating displays, but measured at a 15-degree angle when standing and a 15-degree angle in the vertical.
Contrast
The contrast between a character and the background must be sharp even from angles other than perpendicular to the display. Contrast modulation (Cm) must be Cm >=0.8 at 30 degrees in the horizontal.
Display frame
The display frame must not give rise to disturbing reflections.
An earlier requirement specified that the frame should not be too dark or too light but this was removed in October 2005. Nevertheless, it is still important to avoid strong contrasts in our field of vision, as described in The Advisor for displays. This is also something the user should consider him or herself when choosing a display.
Color reproduction
The display must have a preset color temperature that can be adjusted by the user. Color reproduction must be even over the entire display surface. Colors must not be distorted when viewed from a side angle.
Workload ergonomics
It must be possible to adjust the display in the vertical by at least 20 degrees.
The display must be height adjustable. (It is particularly important to be able to lower very large displays down to the table surface.)
Emissions
Alternating electrical fields must be a maximum of:
- Band I: 5 Hz to 2 kHz, <= 10 V/m, measured at 30 cm and 50 cm in front of the display.
- Band II: 2 kHz to 400 kHz, <= 1.0 V/m, measured at 50 cm around and 30 cm in front of the display.
Alternating magnetic fields must be a maximum of:
- Band I: 5 Hz to 2 kHz, <= 200 nT, measured at 30 cm in front of and 50 cm around the display.
- Band II: 2 kHz to 400 kHz, <= 25 nT measured at 50 cm around the display.
Noise levels (measured in Bel) from fans, etc. must not exceed a maximum:
- 4.4 B in operating mode
- 3.9 B in idling mode
If the product does not emit any disturbing tones, higher noice levels are accepted, but must not exceed
- 4.7 B in operating mode
- 4.2 B in idling mode
Electrical safety
The display must fulfill the safety requirements of
EN/IEC 60 950.
Ecology
To minimize environmental impact, the display must:
- Be manufactured in accordance with ISO 14001/EMAS.
- Contain limited amounts of heavy metals such as mercury, cadmium, and lead (Displays certified after 1 July 2006 also meets the RoHS directive).
- Contain limited amounts of brominated or chlorinated flame-retardants (Displays certified after 1 July 2006 also meets the RoHS directive).
- Be prepared for recycling to facilitate material recycling.
- Be equipped with information stating where it can be recycled.
Energy
The display must be fitted with an energy saving function that ensures power consumption of a maximum of 2W in the lowest standby mode. From 1 January 2006 the power consumption may not exceed a maximum of 1W in the lowest standby mode and a requirement on power consumption in active mode will also be included.
