@OskarsS, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
I understand how frustrating it can be when your HP Omen 17 suddenly shows a black screen, especially after a hard reset. Let's walk through some steps to help you get your display back.

Step-by-Step Troubleshooting:

Perform a Hard Reset Again

Sometimes the first reset doesn’t fully clear the hardware state.

1. Power off the laptop completely.
2. Disconnect all external devices (USBs, HDMI, etc.).
3. Unplug the power adapter.
4. Press and hold the power button for 30 seconds.
5. Reconnect the power adapter and try powering on.

Try External Display Again

Reconnect to your TV or monitor via HDMI:

• Power on the laptop and immediately press Windows + P multiple times to cycle through display modes (Duplicate, Extend, Second screen only).
• Wait a few seconds between each press to see if the external display activates.

BIOS Recovery (Blind BIOS Reset)

If the screen is black even during boot, try a BIOS recovery:

1. Turn off the laptop.
2. Press and hold Windows + B keys, then press and hold the Power button for 2-3 seconds.
3. Release the power button but keep holding Windows + B for another 10 seconds.
4. If successful, you may hear beeps and the BIOS recovery screen should appear.

Reset CMOS (if accessible)

If you're comfortable opening the back panel:

• Disconnect the battery (if removable).
• Locate and remove the CMOS battery for 5 minutes.
• Reinsert it and try booting again.

Only attempt this if you're experienced with laptop internals or have support.

Check for POST (Power-On Self-Test)

• Power on the laptop and listen for beeps or fan behavior.
• If there are no beeps and the fan runs continuously, it could indicate a hardware issue (GPU, motherboard, or display cable). 

I hope this helps. 

Take care and have a good day.
