  • Hi charwaka,

    As you have mentioned that the same display cable is working fine on the different computer, did you try connecting a different monitor to the computer?

    If the monitor has a built in self-test feature in it, please run the built in self-test on the monitor to confirm monitor is working fine.

    As the power button on the computer is solid white, check if the computer is giving out any beep sounds, and make a note of the beeps and post the beep count.

    Please reply for further help.

    Thanks & Regards,

  • Hi charwaka,

    There are a few steps that you can try before coming to a conclusion. Updating the video card drivers could help. To find the right video card driver for the system, please private message me the service tag of the system, I will check the specification of the Video card present in the computer and provide appropriate drivers for the same.

    To private message me, click my user name, click Add as friend, and click start conversation and send the service tag of the system.

    Awaiting your response.

    Thanks & Regards,
