My computer is suddenly in this situation, just asked colleagues, explanation is not so convincingWhat's the reason for that?
Simply put, there is unlimited electrical transmission around the monitor (cell phones, phone calls, text messages)The larger magnetic field passes (the speakers are too close)Fluctuation of voltage (larger electrical appliances are switched on)
The magnetic field is too general to arise this kind of problem. If after every time turn on the machine, always appear this kind of circumstance, suggest to take back the place that buys to repair. Most of them are all bad
Cause analysis of display screen jitter:The resolution of the display is low (the higher the resolution, the better the resolution, the better the removal of the "drag shadow") and in any case does not affect the motion of the picture. The picture jitter is a series of interference in the line or field signal. The cause of the fault is usually the power supply of the monitor, the filter electrolytic capacitor is inefficient, and the update is good.
There is a strong electromagnetic source around itDid you put it next to your cell phone?Or a very close place where the induction cooker or something?There are also ADSL cats and larger routers that seem to cause jitter
