Q:The monitor seems to be flickering. What can I do? |
| |
Answer:
Please check the pins of signal connector. If the pins are bent or lost, please contact the dealer. A wrong setting of the display card is the cause for a flickering screen. See “ How do I set the scan rate ?”Or check scan rate , and set the display card to acceptable range |

Q:How do I set the refresh rate? |
In order to set the refresh rate, please follow the next steps:
Click “start”, click on “settings”, choose “control panel
In the window which then opens you click”display
Note: you can also get to this stage by clicking on a free space on your desktop with the right mouse tap and by choosing “properties”
The window which will then pops up is called “display properties”
Please click “settings” and click “advanced” on the right below
Click “monitor” in the window which then pops up.
You can now adjust the refresh frequency in the option area “refresh frequency rate”. In most cases the human eye does not notice a flickering screen anymore, starting from a refresh frequency at the rate of 72Hz. This is, however, also depends on the techniques and surrounding facts. By confirming both windows with “OK”, the new setting will be adjusted!
The chosen setting may possibly be tested for 15 sec. If you do not confirm the requirement “maintain chosen settings?”. E.g because the monitor cannot display the chosen refresh frequency, the former setting will be restored after that period of 15 sec. |

How are the resolution and graphic card associated together?
It depends on your graphic card which resolution options are available. Depending on the performance and memory qualities of the graphic card that is being used, the colour quality as well as the refresh frequency can be reduced when choosing high resolutions. With modern devices possible settings are pinpointed by the exchange of data(DDC) between those devices. The monitor conveys its maximum and/or ideal operating parameters to the graphic card. The graphic card will then set itself on the ideal rate or it will reduce the chosen setting to the one which is possible for this monitor. |

Q: The screen is getting worse after having connected my signal cable via an extension? |
Answer :
To guarantee an ideal display quality , try to avoid using an extension cord because by doing this, the signal quality will be drastically reduced and the picture displayed will be worse. Should you not be able to do without an extension please use a high-valued cable. |

Q: What are pixel faults and in which case is it a warranty claim? |
Answer:
Pixel faults are defined in the norm ISO 13406-2. One screen dot(pixel) is made up of three colourful dots(subpixels): thus a green, a red and a blue subpixel form one pixel. Due to different types of brightness of the singular pixels, different colours are displayed. If all three subpixels are activated, you will have one white lit pixel, if all three subpixels unlit, you will have a black pixel. If only one subpixel is defective(always white or always black), the pixel shows a wrong colour.
The following pixel faults are permitted to show without warranty claim:
3 white pixels(full screen dots)
or
3 black pixels(full screen dots)
or
7 faulty subpixels(singular dots) |
