What's the reason for the water ripple on the monitor screen?
Graphics cards, signal lines, the display itself failure, will cause this phenomenon.First of all, to exclude, reduce the scope of failure, you can connect the monitor to a normal host, tested. If the confirmation is the monitor question, mostly concentrates in the monitor, in the power supply circuit has the capacitor to be invalid, causes the exchange ripple to be too big, displays in the screen is the ripple pattern.At the same time, do not ignore the point, the surrounding environment there is interference will cause this phenomenon, you can try another location. (I have encountered a liquid crystal display that ripples over a cordless phone.)
Put the monitor on another host and try, and if not, that's the problem with your host. If so, that's the problem with your monitor. There are water ripples are usually caused by interference, or poor filtering.
A fine view around the computer (within one meter) if there is interference, such as equipment, refrigerators, electric fans, hair dryer, uninterruptible power supply, voltage regulator, fluorescent lamp with magnetic interference, if there are two computer monitor is very close (within one meter), also can make the appearance of the two small ripple interference the brain on the screen. The method is to remove equipment with interference from the computer. If the problem is not resolved, contact the computer repair center.
