The graphics card is running normally but there is no signal on the monitor.

The computer host starts up and runs normally, why does the monitor display no signal?

The monitor data cable host connection is loose or has fallen off. First check the physical connection. Check whether the connection between the computer host and the monitor is stable.

Cable problem: Check whether the connection line between the computer monitor and the host computer is stable. If the connection is poor or damaged, the monitor will be unable to receive signals, resulting in a black screen. Monitor issues: If your computer is working normally but your monitor is not responding, there may be a problem with the monitor itself.

The computer host is running normally and the monitor has no signal. The reasons are as follows: the monitor data cable host connection is loose or has fallen off. First check the physical connection. Check whether the connection between the computer host and the monitor is stable.

The computer host light is on, but the monitor shows no signal. There may be several reasons: The monitor and the computer are not connected properly: Please confirm whether the connection between the monitor and the computer is correct, including the power cord, VGAHDMIDP and other video cables.

The graphics card is on but there is no signal on the monitor

It may be that the external wiring connection is not good. It may be that the motherboard is deformed, causing no signal. It may be that the parts are burned due to excessive temperature due to long-term use. The graphics card is desoldered. Suggested solution: First check the computer's external wiring. If not connected properly, the monitor will have no signal.

When the monitor display is on but there is no signal, this is usually caused by the following reasons: Poor signal cable connection: Confirm that the signal cable you are using (such as VGA, HDMI, etc.) is properly connected to the computer and monitor between interface. Make sure the plug is tight and make sure the signal wire isn't locked in place causing it to not connect.

You can use the following methods: Troubleshooting method: First check whether the replaced graphics card model is compatible. For example, if the old graphics card was from ATI, but you replaced it with an NVDIA graphics card, this will definitely not work. The old graphics card driver is still on the computer, and it will definitely not work if the new graphics card is not compatible with the old one.

: First of all, generally speaking, the monitor shows no signal because the monitor’s data cable has fallen off. Make sure the connection is normal. 2: If the monitor shows no signal, it may be that the monitor’s data cable is broken and the data cable needs to be replaced.

If the monitor shows no signal, it may be a problem with the graphics card, or it may be a loose memory stick. It's not necessarily a graphics card issue. Check the graphics card and monitor interface, and re-plug and unplug the memory stick. If it doesn't work, wipe the gold finger of the memory stick with hard paper and try plugging it back in again. Finally, check the cable and graphics card.

The monitor shows no signal, indicating that the monitor is powered on normally. If the host is running normally, it is recommended to cut off the power supply of both the monitor and the host, then remove the connection cable between the monitor and the host and reconnect it. Pay attention to whether the pointer of the monitor connection cable is damaged.

Both the monitor and the computer are good, why does the monitor always show no signal?

1. It is caused by the monitor not receiving the signal transmitted by the host. Generally, the data cable and connection are loose or the data cable is damaged. It is caused by four main reasons: poor contact of the memory module and motherboard failure.

2. The computer display shows no signal in the following situations: Pay attention to whether the motherboard light is on, the CPU fan is not spinning, and the power supply fan is not spinning. If there is no alarm, it is estimated that the motherboard may be more damaged; if the CPU frequency set in the CMOS of the jumper-free motherboard is incorrect, it may also cause a no-display fault.

3. When the computer is turned on, the screen is black and the LCD screen displays "No Signal". It may be that the desktop host is in poor contact with the video cable connecting the monitor. Especially if the interface is not plugged in or is loose, there may be something wrong with the connected data cable. Just unplug the data cable again. Or replace the data cable.

4. If the host starts up and runs normally and there is startup music, then the signal cable connecting the monitor and the host may be loose or have poor contact. You need to check whether the video output cable is loose or connected in the wrong position. Hosts with graphics cards need to connect the video output cable to the graphics card. If there is no graphics card, they need to be connected to the motherboard.

The computer has not been used for a long time, but it can start normally. What to do if there is no signal on the monitor

First reconnect the monitor wiring or replace the wiring and try to see if there is a problem with the monitor wiring. If the host has dual graphics cards, replace the other graphics card and test it to see if it is a graphics card problem. Open the case and re-insert and unplug the memory. You can use an eraser to wipe the gold fingers of the memory.

If the host starts up and runs normally and there is startup music, then the signal cable connecting the monitor and the host may be loose or have poor contact. You need to check whether the video output cable is loose or connected in the wrong position. Hosts with graphics cards need to connect the video output cable to the graphics card. If there is no graphics card, they need to be connected to the motherboard.

Check whether the monitor's power cord and signal cable are loose or damaged. If so, you need to replug or replace the cable. Check whether the graphics card driver is normal. If not, you need to reinstall or update the driver.

Solution 1 if the monitor does not light up when the computer is started: Check to see if the keyboard light is on. Press the numlock or caps switch key on the upper left side of the keypad to see if the keyboard indicator light responds. If so, pay attention to the sound of the system starting up. If the keyboard light responds, it means that the system starts normally, but there is no display.
