如果电脑开机时出现 "no signal" 的错误消息,表示显示器无法接收到来自电脑的信号。这可能是由以下几个原因引起的:1. 请确保电脑与显示器之间的连接线(如HDMI、VGA、DVI等)已正确连接,并确保连接牢固。2. 检查显示器是否打开,并且处于正确的输入模式。可以尝试按下显示器上的输入源按钮或菜单按钮...
HDMINo signal,断电开机之后为啥显示没有信号了 解决方案:1. 如果你的机器是集成显卡的:查看是否插错,检查主板是否有问题。2. 如果你的机器原来正常,可能是由于以下原因:内存条或显卡可能因震荡而松脱,长时间不用而生锈,或因环境潮湿、灰尘等原因导致接触不良。解决方法:使用干燥的毛巾或卫生纸擦...
1、如果你的机器是集成显卡的,一看插错没,二看主板。2、如果你的机器原来还好好的,那么可能是内存条或是显卡受到震荡松了,或者时间长锈了,或者环境潮湿接触不良或者进了灰尘。3、拿干燥的毛巾,卫生纸,擦拭内存条或显卡的小铜片(金手指),然后重插即可。4、如果环境潮湿造成的,那么就需要你拿...
Whenever my Lenovo laptop(S145-15IIL Laptop (ideapad) - Type 81W8) is connected to the TV using HDMI cable via a signal switch, the TV cannot receive the signal, but it can be received when connected directly without a switch. This happened to two diff...
I tried to connect the HDMI out to the HDMI in on a podium computer at a college. The Extron Monitor continually shows "No Signal". If it is plugged directly into the scaler, it works fine, but does not work at at when connected to the HDMI in on the top of the podium. Any ...

This time, the monitors are not showing at all, and simply display "No signal" when connected via HDMI or DisplayPort. I know the cables and monitors work since I can connect them to my laptop directly and independently. I can also see the moni...
这一现象有几种可能:1、VGA信号线故障;2、显卡故障;3、内存故障;4、主板或CPU故障;下面我分别来说一下如何确定故障点。首先,开机听一下有没有主板发出的“滴”一声(大约在主机接通电源5-6秒钟发出),这是主板自检声,如果有这一声,说明:内存、主板或CPU正常。那么就是VGA信号线或显卡的...
这个提示是显示器没有信号输入,这种情况一般是主机硬件故障或者接触不良导致的,拔插内存,清理金手指,或者换条内存试试,不行的话,如果是独立显卡,同样方法检查显卡,再不行,就看看主板是否有电容爆浆等明显损坏,或者换个主机电源试试,还不行的话,就只能把电脑主机送修了 ...
1、更换HDMI线,2、检查线是否接触良好,表面是否有污渍,3检查电脑硬件查看是否有驱动问题(有个三角感叹号)如果有问题更换驱动。4看你是先开的显示器还是待机显示器开主机,没开主机先开显示器当然没信号。
