The assembled new host is connected to the display without a signal

Asked by: Marie 225 views Hardware February 26, 2019

The newly assembled host, the system and the sub-discs that others gave me in the computer city, was no problem on other people's monitors at the time; but when I came back to connect the monitor, the monitor showed no signal, the host was fine, but I used the monitor. Connected to my laptop can be displayed, indicating that the display is no problem, if my host connected to the display will show no signal, which is the problem

    A very simple question, see the connector connected to the computer, you must be plugged in the nuclear display, the actual machine has a separate display, take a look at it

    You have inserted the wrong place. Many motherboards have a display output interface. When you use a discrete graphics card, be careful not to insert the wrong location.

    Surely some lines are not connected.

    If you don’t have the right one, look for it, don’t go to the computer for repair.

    Check the graphics card or connection. Then whether the motherboard has its own graphics card or a separate graphics card, if you need to set the priority startup item

    It should be a problem with the monitor

    See if the power contact is not good, or the network problem

    No signal will power out the problem but your monitor is powered independently  The possibility is small  I have encountered a situation where the resolution problem  the host is using other monitors to debug, install the system, etc.  The resolution is set to match that display the display itself There is also a range of resolutions  When the resolution set by the host exceeds the range of the display, it will be black or have other text prompts. For example, if the resolution set by the host is higher than the range of the currently used display or below the range, there will be problems.   But you said that there is no surprise when there is no signal  even if it is a resolution problem, there will be tips Black screen There will be no signal prompts I suggest you adjust the resolution first. Open the monitor first  Look at the resolution range of the monitor in the monitor’s own settings  Remember the value  Use another display that can display the host  to set the resolution of the system output just set the value to remember  then connect the center with the no signal.

    Host Poor internal contact, re-plug all kinds of connectors and boards, and other wiring must be plugged in, such as the independent power supply line, CPU power supply line or something. In addition, if there is a stand-alone display, the connector of the display should not be plugged into the integrated connector.  

    Is it a stand-alone network card or an integrated network card? If the display is not lit, there is no power, graphics card problem, then you have a separate network card, connect the monitor’s data cable to the integrated network card. You check the line. If you don’t have power, look at the power supply at both ends.

    Question: The host can display it when installing the computer. Just take it back and connect it to your monitor. But your monitor and connected notebook can be displayed. , evil door

    You try to connect the data cable connecting the computer and the monitor.
