BenQ 19-inch display appear wavy

Home of the 19-inch BenQ monitor the emergence of waves.How to solve?

In rare cases, LCD display screen will appear Miscellaneous interference pattern.This may be the VGA card is caused by the frequency, you can try to manually or automatically through the adjustment phase and as few frequencies to improve the image quality.Can also check your computer's graphics power, as well as whether the signal output Stable, updated graphics driver, to replace the data lines as well as to test the power cord, in order to rule out the possibility of non-display, if the problem still exists, contact BenQ Service Center confirmed detection.Your display should not be a problem.You can take this display Other computer 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 is a digital device, 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 identify the liquid crystal display digital signals.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), the clock can not be done, and Vector The analog signal exactly the same.Therefore, to embody the liquid crystal display, there will be now flickering or Shuiwen like.And this is like the flashing display card with the refresh rate has nothing to do:liquid crystal display rather than CRT monitors, it is not an internal cathode Ray tubes, rather than to rely on e-gun attack on the CRT on phosphorus 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, the LCD Did not display electron gun and line by line interlaced scan of the principle of the screen (LCD display work from beginning to end points of each pixel are luminous, flashing phenomenon does not exist), and refresh rate does not exist the concept of change have not changed a kind, refresh rate All of the LCD are not working.Displayed on the display card has adaptive function, 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 It will be impossible to 85Hz.This is the most basic common sense.

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

Solution:
1) If your And computer display monitors have a digital interface card, then strongly recommended 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), then you need to look at the The use of the computer environment, reduce electromagnetic radiation monitor data on the impact of the line (for example, as far as possible, so that the VGA line is far from the main chassis, will surely opt for a magnetic ring with two ends of the product line), multimeter check the voltage at home Is not a stable (if necessary, display the best and do not have to play host to share a row), whether the current pure, ground Paicha the ground are in working order, and so on.

Finally, the liquid crystal display or strongly recommend the use of digital DVI Interface (This is the first to buy liquid crystal display when it 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 analog D-SUB The old user interface graphics cards, not to give up this market has done.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).
