According to pro-poor development, timely adjustment on 2、显卡驱动问题，重装显卡驱动 先检查显卡驱动 再看看内存和显卡 都没问题就换显示器的硬件 显示器用的时间长了，各种小毛病就会接踵而来。要解决这些小毛病实际上很简单，用一双眼睛就可以看出故障的所在。 3、电源变压器离显示器和机箱太近 电源变压器工作时会造成较除夜的电磁干扰，除夜而造成屏幕抖动。把电源变压器放在远离机箱和显示器的处所，可以让问题水到渠成。 4、音箱放得离显示器太近 音箱的磁场效应会干扰显示器的?俘常工作，使显示器发生屏幕抖动和串色等磁干扰现象。 5、病毒捣蛋 有些较劲争论机病毒会纷扰扰攘侵略屏幕显示，比如:字符倒置、屏幕抖动、图形翻转显示等。网上处处可见的屏幕抖动脚本，就足以让你在中招之后头除夜如牛。 6、显示卡接触不良 重插显示卡后，故障可获得清扫。 WIN95/98系统后写缓存引起,如属于这种原因，在节制面板-系统-机能-文件系统-疑难解答中禁用所有驱动器后写式高速缓存，可让问题获得根调整决。 7、电源滤波电容损坏 打开机箱，假如你看到电源滤波电容(电路板上个头最除夜的阿谁电容)顶部鼓起，那么便申明电容坏了，屏幕抖动是由电源故障引起的。换了电容之后，即可解决问题。 electricity at no cost, revenue from electricity sales.

According to pro-poor development, timely adjustment on 8、显卡老化 需要替代... 备注:如果还是不懂或者问题还是没有解决，可以去电脑高手网询问。 常见故障一:开机抖动 电脑刚开机时显示器的画面抖动得很厉害，有时甚至连图标和文字也看不清，但过一二分钟之后就会恢复正常。 这种现象多发生在潮湿的天气，是显示器内部受潮的缘故。要彻底解决此问题，可使用食品包装中的防潮砂用棉线串起来，然后打开 显示器的后盖，将防潮砂挂于显象管管颈尾部靠近管座附近。这样，即使是在潮湿的天气里，也不会再出现以上的“毛病”。 常见故障二:闻其声不见其画 电脑开机后，显示器只闻其声不见其画，漆黑一片。要等上几十分钟以后才能出现画面。 这是显象管座漏电所致，须更换管座。拆开后盖可以看到显象管尾的一块小电路板，管座就焊在电路板上。小心拔下这块电路板，再 焊下管座，到电子商店买回一个同样的管座，然后将管座焊回到电路板上。这时不要急于将电路板装回去，要先找一小块砂纸，很小心地 将显象管尾后凸出的管脚用砂纸擦拭干净。特别是要注意管脚上的氧化层，如果擦得不干净很快就会旧病复发。将电路板装回去就大功告 成。 常见故障三:干扰杂波 显示器屏幕上总有挥之不去的干扰杂波或线条，而且音箱中也有令人讨厌的杂音。 如果未过保修期的话，你可找相关部门去理论，如果已过了保修期的话，您可先更换一个+300V的电容试试，也可以试着自己更 换电源内滤波电容，这往往都能奏效;如果效果不太明显，可以将开关管一并换下来。 ，如果无效就要交付专业维修部门了。还有就是显卡的质量有问题 electricity at no cost, revenue from electricity sales.

According to pro-poor development, timely adjustment on 常见故障四:显示器花屏。 这问题较多是显卡引起的。如果是新换的显卡，则可能是卡的质量不好或不兼容，再有就是还没有安装正确的驱动程序。如果是旧卡 而加了显存的话，则有可能是新加进的显存和原来的显存型号参数不一所致。 常见故障五:显示器黑屏。 如果是显卡损坏或显示器断线等原因造成没有信号传送到显示器，则显示器的指示灯会不停地闪烁提示没有接收到信号。要是将分辨 率设得太高，超过显示器的最大分辨率也会出现黑屏，重者销毁显示器，但现在的显示器都有保护功能，当分辨率超出设定值时会自动保 护。另外，硬件冲突也会引起黑屏。 有时主机由于主机的原因也会造成黑屏现象，但无论您怎么拍打彩显机壳也不会有所好转，所以有条件的话可将显示器接到别一台确定无 故障主机上试试看。另外，目前有很多显示器在拔掉连在显卡上的信号线后就会出现自检显示功能，如果显示正常就说明显示器基本无故 障，故障点在信号线或显卡上，这样一来就能更方便地找到故障点了。 常见故障六:图像扭曲变形 其常见故障点通常是行或场的某校正电路出现了问题(比如S校正电容等)，由于维修起来要有一定的专业知识，所以笔者您交付家 电维修部门进行维修。当然，如果故障是在您对显示器进行了什么操作后出现的话，那么您可先参照#说明#进行一些调试校正工作试试， 只要您详细看过说明书通常都能搞定～ 常见故障七:系统无法识别显示器 显示器出了硬件故障或某元件性能不良所致，显卡出了硬件故障或显卡驱动程序损坏所致，显示器和显卡相连的数据线出现 了问题,VGA插座出了问题.未安装显示器厂家的专用显示器驱动程序所致. 常见故障八: 屏幕闪烁故障 如果把显示器的分辨率和刷新率设置得偏高或过低的话也可能造成此类故障，所以可把分辨率和刷新率设置成中间值试试(注:长期 工作于超频状态会使某些元件老化而出现此故障，而且故障点比较难找)。还有就是显卡或显示器electricity at no cost, revenue from electricity sales.

According to pro-poor development, timely adjustment on 的驱动程序存在BUG，所以要先更新 一下驱动程序试试。如果以上处理均无效，可重点检查一下高压包产生的加速极电压和高压是否正常，因为有时这两个电压异常也会导致 此类现象。注:如果打开电视机也有闪烁的话，那就要先查一下市电电源是否存在问题了——如容量太小或电压波动过大等(最好找电工 检查)。 有时一些带磁物品(如一些低档电源盒或ADSL外猫电源等)放在显示器附近会造成屏幕的某一个角闪烁，所以遇到此现象要先试 着清除显示器周围的物品看看，通常问题都能得到解决。 液晶显示器常见故障 1、出现水波纹和花屏问题 首先要做的事情就是仔细检查一下电脑周边是否存在电磁干扰源，然后更换一块显卡，或将显示器接到另一台电脑上，确认 显卡本身没有问题，再调整一下刷新频率。如果排除以上原因，很可能就是该液晶显示器的质量问题了，比如存在热稳定性不好的问题。 出现水波纹是液晶显示器比较常见的质量问题，自己无法解决，建议尽快更换或送修。 有些液晶显示器在启动时会出现花屏问题，给人的感觉就好像有高频电磁干扰一样，屏幕上的字迹非常模糊且呈锯齿状。这 种现象一般是由于显卡上没有数字接口，而通过内部的数字/模拟转换电路与显卡的VGA接口相连接。这种连接形式虽然解决了信号匹 配的问题，但它又带来了容易受到干扰而出现失真的问题。究其原因，主要是因为液晶显示器本身的时钟频率很难与输入模拟信号的时钟 频率保持百分之百的同步，特别是在模拟同步信号频率不断变化的时候，如果此时液晶显示器的同步电路，或者是与显卡同步信号连接的 传输线路出现了短路、接触不良等问题，而不能及时调整跟进以保持必要的同步关系的话，就会出现花屏的问题。 2、显示分辨率设定不当 由于液晶显示器的显示原理与CRT显示器完全不同，它是属于一种直接的像素一一对应显示方式。工作在最佳分辨率下的 液晶显示器把显卡输出的模拟显示信号通过处理，转换成带具体地址信息(该像素在屏幕上的绝对地址)的显示信号，然后再送入液晶板 ，直接把显示信号加到相对应的像素上的驱动管上，electricity at no cost, revenue from electricity sales.

According to pro-poor development, timely adjustment on 有些跟内存的寻址和写入类似。所以液晶显示器的屏幕分辨率不能随意设定，而传统 的CRT显示器对于所支持的分辨率较有弹性。LCD只能支持所谓的“真实分辨率”，而且只有在真实分辨率下，才能显现最佳影像。 当设置为真实分辨率以外的分辨率时，一般通过扩大或缩小屏幕显示范围，显示效果保持不变，超过部分则黑屏处理。比如液晶显示器工 作在低分辨率下800*600的时候，如果显示器仍然采用像素一一对应的显示方式的话，那就只能把画面缩小居中利用屏幕中心的那 800*600个像素来显示，虽然画面仍然清晰，但是显示区域太小，不仅在感觉上不太舒服而且对于价格昂贵的液晶显示板也是一种 极大的浪费。另外也可使用插值等方法，无论在什么分辨率下仍保持全屏显示，但这时显示效果就会大打折扣。此外液晶显示器的刷新率 设置与画面质量也有一定的关系。朋友们可根据自己的实际情况设置合适的刷新率，一般情况下还是设置为60Hz最好。 此文来源于冒1冒新浪博客: ，欢迎到冒1冒博客坐坐，里面很多相关精彩哦。 electricity at no cost, revenue from electricity sales.
