ViewSonic VA1916W resolution for 1440X900 60 Hz screen shaking What is the problem?

power line data for less than your monitor is no problem.You can display this to other computers to try to see if There is the problem.

You are not using the D-SUB analog interface to connect the monitor? This means that you are using the VGA of the first blue line.

This is because the liquid crystal display Digital equipment, if still use the traditional CRT monitors analog interface of the times, we need to computer graphics, through the digital signal is converted to analog signals through transmission lines to the VGA liquid crystal display, and then converted to analog signals to liquid crystal display Recognition of the digital signal.As the analog signal itself due to the principle, the analog signal transmission through the cables in the course of a very vulnerable to outside interference (such as electromagnetic radiation), do not clock frequency, analog and vector signal exactly the same.Therefore, to reflect the Liquid crystal display, there will be now flickering like.And this is like the flashing display card with the refresh rate has nothing to do:liquid crystal display rather than CRT monitors, and its in-house instead of cathode ray tubes, rather than to rely on e-gun attack on the CRT-P Powder produced images.Liquid crystal display on the back of the lamp is lit up in front of the LCD panel and the light-emitting passive, and not only the bright lights, the difference between dark and the next.Therefore, no liquid crystal display electron gun and line by line interlaced scan of the principle of the screen ( LCD monitors work, each pixel has all luminous, flashing phenomenon does not exist), and refresh rate does not exist the concept of change does not have a change like that all the refresh rate on the LCD were not working.Displayed on the card There are adaptive display functions, when you plug in the liquid crystal display, the card will automatically refresh rate option does not work, so as to protect the LCD.Therefore, in Windows, you can not be transferred to 85Hz.This is the most basic Common sense.

Digital interface (DVI) completely non-existent over the issue.

Solution:
1) If your computer monitor and video card have digital interface, so strong Suggest that you use DVI digital interface to connect.
2) If you do not have the liquid crystal display DVI digital interface (or your video card does not DVI digital interface), you need to check your computer to use the environment, reduce electromagnetic radiation monitors on-line data The impact (for example, as far as possible, so that the VGA line is far from the main chassis, the best choice with both ends of the electromagnetic ring product line), multimeter check the voltage at home is not a stable (if necessary, do not have to display the best And play host to share a row), the current is pure, ground Paicha the ground are in working order, and so on.

Finally, or strongly recommend the use of liquid crystal display DVI digital interface (this point in the first place to buy liquid crystal display when Should take into account the fact that only a D-SUB (analog), which is the interface of liquid crystal display manufacturers is to compromise the performance of the consumer, in order to take care of those, only D-SUB old analog interface card users, and not to give up on this Done by the market.Technically speaking, an increase in the number of artificially-mode, analog-digital conversion process, there is absolutely no need to create trouble in itself is very funny).
