Omen 870 monitor display problem

[Brownie44]

I have a brand new just out of the box Omen 870-157c

I have plugged in the power cable, keyboard and mouse in USB, and cable to the modum.

I have plugged the HDMI cable into the video card (not the HDMI 1 or 2 for the mother board)

My problem is:

I only see on the monitor a red diamond shaped icon in the center of the monitor and nothing else.The monitor works fine when connected to a different computer.

When i turn on the Omen it sounds like it starts up ok. lights are on ond the fan is running.

I have tried plugging into the other two HDMIs but they do not work.

I know the HDMI cable is ok.  Ihad it on a different unit.

I have tried all the keys on the keyboard and the mouse.

Where do I go from here?

Hello;

Allow me to welcome you to the HP forums!

Since your PC apparently comes with both onboard video and a separate video card, from your description, either (1) the video card itself is bad, or (2) when HP configured your PC, they did not configure it properly to use the video card as the default video device.

Unfortunately, without video on your PC, there is really nothing we can do from here to have you diagnose these problems.

You paid for free HP Tech Support as part of the warranty coverage, so you might as well make use of it.

While this PC is still under warranty, you should contact HP Customer Support directly to have them put you in touch with HP Technical Support to see what they can do about troubleshooting and repairing your machine remotely.

I did this recently and the HP Tech was able to remotely access my PC from the Internet and do the needed repairs.

NOTE: After you get through, stay on the line until you are finally able to talk to some one -- it can take a while!

If you have trouble finding a phone number, then try: 1 (800) 474-6836

Good Luck

Dean,

I followed your suggestion to contact a live HP tech support person.  They were able to resolve my problem on the phone. It took awhile but my computer is up and running like it should.  HP tech support was knowledgeable, friendly, patient.  I could not have asked for a better experience on the phone with a tech support person.  Hats off to  you and HP for a very satisfying  experience.
