Question:

What could cause a monitor to not detect a signal from a newly installed Windows PC?

I recently replaced the SSD of my old computer and installed Windows on it. I shipped the computer to my sister, who is using a different monitor than mine. When she tries to connect the monitor to the computer, either through the graphics card or the motherboard ports, the monitor says no input. The monitor works fine with her laptop. The computer seems to be running normally, as the keyboard and mouse light up. Could the problem be related to me turning off the computer before setting up the Windows account, or to some damage during the shipping? The computer was transported by car and did not appear to be harmed.

Answer:

If you have recently installed Windows on a new or old PC, you might encounter a problem where the monitor does not display anything when you turn on the computer. This can be frustrating, especially if you have shipped the computer to someone else and cannot troubleshoot it yourself. In this article, we will explore some of the possible causes and solutions for this issue.

Cause 1: Incorrect or loose cable connection

One of the most common reasons why a monitor does not detect a signal from a PC is that the cable connecting them is either not plugged in properly, or is faulty or incompatible. This can happen if you use a different monitor than the one you used before, or if the cable was damaged during the shipping.

To fix this, you should check the following:

• Make sure the cable is securely connected to both the monitor and the PC, and that it matches the port type (HDMI, DisplayPort, VGA, etc.).
• Try using a different cable, or a different port on the monitor or the PC, if available.
• If you have a graphics card, make sure the cable is connected to the graphics card port, not the motherboard port. If you have multiple graphics card ports, try switching between them.
• If you have a monitor with multiple input sources, make sure you select the correct one using the monitor’s menu or buttons.

Cause 2: Incorrect or missing display driver

Another possible reason why a monitor does not detect a signal from a PC is that the PC does not have the correct or updated display driver installed. This can happen if you have installed a new operating system, such as Windows, or if you have changed the hardware, such as the graphics card.

To fix this, you should do the following:

• If you have access to another monitor or a TV that works with the PC, connect it and use it to install or update the display driver. You can download the driver from the manufacturer’s website, or use Windows Update to automatically find and install the best driver for your device.
• If you do not have access to another monitor or a TV, you can try booting the PC in safe mode, which uses a basic display driver that should work with most monitors. To do this, press and hold the F8 key as soon as you turn on the PC, and select Safe Mode from the Advanced Boot Options menu. Once in safe mode, you can install or update the display driver as described above.
• If you cannot boot the PC in safe mode, you can try using a USB flash drive or a DVD to install or update the display driver. To do this, you need to create a bootable media with the driver files on it, using another computer. Then, insert the media into the PC, and change the boot order in the BIOS settings to boot from the media. Once booted, you can install or update the display driver from the media.

Cause 3: Hardware damage or malfunction

A less common but more serious reason why a monitor does not detect a signal from a PC is that there is some hardware damage or malfunction in the PC or the monitor. This can happen if the PC or the monitor was dropped, hit, or exposed to extreme temperatures or moisture during the shipping or handling.

To fix this, you should do the following:

• If you suspect that the PC is damaged, you can try testing the components individually, such as the power supply, the motherboard, the CPU, the RAM, and the graphics card, using another PC or a diagnostic tool. If you find any faulty or broken component, you should replace it or contact the manufacturer for a repair or a warranty claim.
• If you suspect that the monitor is damaged, you can try connecting it to another PC or a laptop, using a different cable or a different port, if available. If the monitor still does not work, you should contact the manufacturer for a repair or a warranty claim.
