Users questions:My computer's LCD screen do not know how going on, running water wave patterns will appear when the rock, run one after the situation eased off time, do not know why, look for HP's engineers asked about N times no solve the problem, in the end is a problem with hardware or software problem? Which expert can helpAddress what, kindness without saying thank!
Experts answer: CRT monitor I used to answer a case of water ripples, the answer is this: you say this, there are two possibilities: 1: display their own part of a capacitor switching power supply quality deterioration, and a ripple component caused by interference . You can display received the otherMachine a try. 2: the host computer ATX power supply poor quality, radiation volume, resulting in leakage of electromagnetic radiation by the magnetic field of power, interfered with the normal display monitor. This case, you can move relatively far away the host computer location, or for a magnetic ring with the VGA connection. After IFace up a map, you see the connection of the two, there are two packages, that is magnetic, can effectively reduce the magnetic interference. Similar connection with magnetic ring, and must be better than not to do so. Ha ha. ~~~~~~~~~~~~ Liquid crystal display of common troubleshooting tips: Source: Golden Bridge Information Network issuedCloth :2006-02-221. Huaping problem appears water ripples and the first thing to do is to carefully check the existence of computer peripheral sources of electromagnetic interference, and then replace a graphics card, or receipt of another computer monitor, verify card itself is no problem, then adjust the refresh rate. AsResults exclude the above reasons, it is possible that the quality of the LCD monitor problem, such as the thermal stability of the bad issues. There is a liquid crystal display water ripple of the more common quality problems, they can not solve, the proposed replacement or repair as soon as possible. Some LCD monitors will appear at startup Huaping problem, givesIt felt like a high-frequency electromagnetic interference, like writing on the screen is fuzzy and jagged. This phenomenon usually is due to no digital interface card, while the number of * through the internal analog converter circuit and the VGA connector on graphics card. Although this form of connection to solve the problem of signal matching, but itBrought to interference arising from distortion. The reason is mainly because the LCD display itself is difficult and the input clock frequency analog signal synchronization clock to keep one hundred percent, especially in the analog sync signal frequency of the changing times, if the time synchronization circuit liquid crystal display, orWere synchronized with the video card signal transmission line connected to a short circuit occurs, poor contact and so on, can not be promptly adjusted to maintain the necessary follow-up to sync relationship, it would appear Huaping problems. 2. Display resolution is set properly as LCD and CRT monitors display different principle, it is anOne correspondence of pixels in a direct display. Work under the best resolution of the LCD to display graphics output of the analog signal through the processing, transformation to the specific address information (the pixels on the screen of the absolute address) of the display signal, and then into the LCD panel, directly to the display signal added to the correspondingPixels on the drive pipe, some with memory addressing and write similar. So LCD screen resolution is not arbitrarily set, but the traditional CRT monitors support for the resolution of the more flexible. LCD can only support so-called "real resolution", and only real resolutions toShow the best image. When set to true resolution other than resolution, generally by increasing or reducing the scope screen, display remains the same, more than some of the black handle. Such as liquid crystal displays working in low resolution 800 * 600, when, if the display is still one correspondence with pixelsIs displayed, then it can only reduce the center screen in the center of the screen of that 800 * 600 pixels to display, although the picture is still clear, but the display area is too small, not only feel uncomfortable but also for expensive LCD display board is a tremendous waste. Another plug can also be usedValue and so on, no matter what resolutions remain in full-screen, but this time display will be compromised. In addition, LCD refresh rate settings and the picture quality to a certain extent. Friends according to their actual situation may be appropriate to set the refresh rate, normally set to 60Hz or better
