Display the same water as flash

My corner of the display after the start of a wave like a flash, like “ playing games, but there will not be flash “ Why?

Play games because when the screen moves on very quickly and you will not focus on the flash, he noted that in fact flash

to check your graphics card is not a loose or dirty Goldfinger If the card is not a bad estimate of the radioactive! Your display should not be a problem.You can display this to other computers to try to see if there is the problem.Play games when you do not mind this, so there is no attention, in fact, it should flash.

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 era of traditional CRT monitors analog interface, it will need in the computer graphics, through 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 simulation The principle itself signals caused by analog signal transmission cables through the process very vulnerable to outside interference (such as electromagnetic radiation), do not clock frequency, analog and vector signal exactly the same.Therefore, to embody the liquid crystal display, there will be Shuiwen or flicker are like.

And this is like flashing or Shuiwen with the graphics card 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 electron gun CRT bombardment on the phosphorus powder generated 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 Scanning 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 does not have a change like that all the refresh rate on LCD can not afford to have Role.Display card on display are 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 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, 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), you need to check your computer to use the environment to reduce electromagnetic Radiation monitors data on the impact of the line (for example, as far as possible, so that the VGA line is far from the main chassis number, we must employ electromagnetic ring with two ends of the line VGA products with the power cord, do not buy cheap non-brand-name), check with multimeter About Voltage's home is not a stable (if necessary, display the best and do not have to play host to share a row), the current is pure, Paicha of the earth ground, and so on are in working order.

Finally, or strongly recommend that LCD DVI monitor the use of digital interface (that in the first place 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 only those D-SUB old analog interface card users, and 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) .Your machine next to a large source of the interference it? Is likely to be interfered with.Voltage instability in your home, you buy a voltage regulator
