HP Omen drops HDMI signal when gaming?

[mottcallie]

Hello,

I have encountered a persistent problem when loading games or playing mid-game, in which my display will suddenly go black and indicate "no HDMI signal detected". The issue has occurred across multiple games and multiple gaming platforms (Steam/Subnautica, Battle.net/Diablo II). Audio typically persists for a few seconds before cutting out as well. The only solution is to hit the power button and force the computer to shut down. The PC is just over a year old (so of course out of warranty). However, searching for this issue online indicates it is a relatively common problem with no obvious solution.

So far I have tried the following:
- Running the HP PC Hardware Diagnostic, everything is functioning properly with no issues detected
- Resetting the PC to factory default and reinstalling Windows
- Updating Windows and all other Microsoft products

- Updating NVIDIA drivers
- Switched fan to "turbo" to avoid overheating. I have also monitored the CPU and GPU temperature while gaming and see no signs of overheating

- Replacing HDMI cable

@mottcallie -- indicate "no HDMI signal detected"

This could be a "hardware" problem with your graphics adapter -- it stops sending any stream to the monitor, and the monitor displays that message.

Does the issue happen when watching a Youtube video, or just when playing games that work the graphics adapter to the limits of its capability?

@Itsmyname -- thank you for your prompt response. The issue only happens when playing games. I have not been able to trigger it with anything else such as YouTube videos, running intensive code in MATLAB, watching Netflix, etc. To provide more detail for my examples of when it does crash:

1) When playing Subnautica, the PC typically drops HDMI connection the moment the game has finished initially loading

2) When playing Diablo II, the PC is able to run the game but sometimes randomly drops connection mid-game, sometimes drops connections during animation sequences (e.g. boss death animation), and always drops if I hit the windows button while playing (e.g. to check something in the start menu)

If this were a problem with my graphics adapter, is there a way to test that this is the issue beyond just best guess? Moreover, is this a part that can be easily replaced? I am less familiar with customizing/replacing parts within the computer.

To be able to answer you effectively, we need some information

we need the exact model of your computer, and the product number

Give the full name with the product number P / N

this is not a model:

@mottcallie --  I have not been able to trigger it with anything else such as YouTube videos, running intensive code in MATLAB, watching Netflix, etc.

My impression is that none of those apps are "graphics-intensive".  I can imagine that MATLAB is CPU-intensive, but that it (and Netflix and YouTube) only occasionally displays graphics output, where "occasionally" means only 30 frames per second.  This is in sharp contrast to high-end gaming apps.

A graphics-adapter is one of the easier components of a desktop PC to remove/replace.

(Watch a "how-to" YouTube video.)

It makes sense to try a different graphics-adapter (borrowed from friend/family?) to see if that "swap" eliminates the symptoms.  Or, find a computer store with a "no-questions-asked-money-back-guarantee-within-3-days" policy, and buy a graphics adapter from that store, and test it.
