I turned of my hp omen after playing siege than when i turned it back on it stayed at a black screen. I tired to listen if i could hear anything but nothing. Than i switched HDMI’s. And the monitor turned on but says the HDMI ports are inactive

Hello @Mikeqny 

Can you tell me the full model or product number of your omen?

Which HDMI ports are you using?

If your Omen Desktop has a dedicated video card, you can only use the HDMI port on that card.

The HDMI port on the motherboard IO shield will not work.

Like this example photo.....

If you unplug the power cord, then hold down the power button for 10 seconds, then plug the power cord back in and turn on the computer, does the monitor work now?

@photoray002 i held the power button after unplugging and it did turn on then i hit restart and then  it stayed at a black screen again
