工具/原料:
系统版本:windows10系统
品牌型号:华硕a豆15
方法/步骤:
问题一:分辨率发生不正确
显示器黑屏但灯亮的原因有可能是因为显示器分辨率不正确。显示分辨率(显示屏分辨率)就是指显示屏图形的精度,显示器能够显示的清晰度有多少。
处理方法:将电源线插上去,开启电脑等待灯亮之后,按CTRL +ALT+ F7恢复默认的分辨率。还可以根据更改计算机的分辨率,来处理显示器黑屏但灯亮的问题。
问题二:VGA接连线有问题
VGA接连线即视频传送规范连接线。一般连接有问题的话也会导致电脑显示器黑屏但灯亮。
处理方法:检查视频信号连接线有VGA、HDMI、DP等连接线,是不是有线路断裂和磨损等问题。假如发生线子破裂、损坏等的问题,换一条VGA线就可以了。
问题三:显卡出问题
显卡又被称为显示电源适配器,是电脑重要的硬件配置之一,担负輸出显示图型的任务。
处理方法:重新安装显卡。操作步骤是,拆卸主机箱上显卡位的隔板,将显卡的金手指擦洗整洁,指向电脑主板上靠CPU处的长内存插槽稍用力插下来,再插好显卡的外置电源线,将显示器连接到显卡的輸出插口,随后接入主机电源开机,系统会提醒你安装新硬件配置驱动的提醒,将显卡光碟放进光驱(要是没有光驱,很有可能在其它有光驱的计算机上把驱动光碟的文件拷到U盘后再应用也行),选择好驱动程序途径,随后一路下一步,进行后重新启动一下计算机就可以了。
问题四:计算机病毒毁坏
在电脑中毒的情况下,会破坏电脑的某些硬件或软件程序等,也会导致电脑显示器黑屏但灯亮的情况发生。
处理方法:启动计算机时按住CTRL键,或在开机在进到Windows系统启动画面以前按住F8键。 进到安全模式后开展杀毒就可以了。
总结:
以上便是常见的电脑显示器黑屏但灯亮的解决方法,多是硬件等因素导致,大家需要一一排查修复解决。有遇到类似问题的小伙伴可参照教程去操作哦。
