Issue with HP Omen 16 External Monitor Flickering

Hi everyone,

I have an HP Omen 16 laptop with a Ryzen 7 5800H CPU and a Radeon RX 6600XT GPU. I'm experiencing a persistent issue when I connect my laptop to an external monitor via HDMI. The screen flickers to black intermittently, and the mouse cursor resets to the center of the screen. This issue occurs in various applications, including Chrome, Blender, DaVinci Resolve, and Windows File Explorer.

Here are the details:

* The problem only occurs when the laptop is connected to an external monitor via HDMI. * The screen flickering never happens when I'm not connected to an external monitor. * The issue does not occur while playing video games, possibly because I play them in fullscreen mode. * The problem persists even after disabling hardware acceleration in Chrome. * When the issue happens in Windows File Explorer, the screen goes black and then comes back, but the file navigator remains partially black until I hover the mouse over the items to refresh their display. * I have confirmed that the HDMI cable is not the issue, as it works fine with other devices. * LatencyMon indicates high DPC latency with spikes in DirectX and Windows WFD driver when the issue occurs, and there are also audio glitches constantly. * Sometimes, I also see glitch particle effects on the screen when the issue occurs.

Things I've tried:

1. Updating all drivers (graphics, display, etc.). 2. Disabling G-Sync/FreeSync both in the monitor settings and in the GPU settings. 3. Adjusting power management settings to high performance. 4. Monitoring and controlling the temperatures to prevent overheating. 5. Reinstalling graphics drivers using DDU (Display Driver Uninstaller). 6. Testing with a different HDMI cable and monitor.

None of these steps have resolved the problem. If anyone has encountered a similar issue or has any suggestions on how to fix this, I would greatly appreciate your help!

Thanks in advance!
