Individual checks suppose that there’s no faulty with the hardware components itself. May be if you have VGA Onboard the bios has disabled the option and this caused the issue.

Enter the Bios set up and ensure that the Onboard VGA feature is enabled. Also check the VGA cable and the all 15 pins are straight and not damaged in the monitor out. If you can clean the both ports with a brush and then wash it with surgical spirit.

There is also an issue with the refresh rate of the LCD Monitor. Set the refresh rate to a low value in between 60 Hz- 75 Hz depending on the LCD specifications labeled on the back of the monitor. Finally do a CMOS clear and see if the display is ok. Otherwise you need to consult a technician to fix the issue.

Since you already checked some of your computer’s devices using a different computer, might as well check your LCD monitor on that computer if it works there. I think you are using an onboard video card because it is not included in the devices you checked and tested on the other computer.

If you are using an onboard video card or a built-in video card, try following the steps mentioned on the above post on how to enable the onboard video card in the CMOS.

But on the other hand, if the graphics card is already enabled, and you are still getting a blank display on your monitor, I think you may need to buy a new graphics card.

It is possible that the built-in graphics card is already broken and not functioning. Please be aware, there are instances where broken onboard devices affect other working onboard devices. That’s why sometimes it’s better to use a separate hardware device than to use the built-in one in the motherboard.
