Problem with the display due to a malfunctioning GPU?
Hello,
I need some guidance about an issue I'm facing with my HP Omen 16 gaming laptop, which is two years old. The specifications are:
- NVIDA GeForce RTX 460 GPU
- Intel® Core™ i7-14700HX (2.10 GHz)
- 1000 GB SSD
- 32 GB RAM
Whenever I connect to an external display (second screen), I encounter intermittent lag, sometimes with both screens briefly going dark and a single beep coming from the laptop body (not the speakers). I've tried using two different screens—one HDMI and one USB C—and the same problem persists. I've updated all available drivers for my display and GPU, including via the NVIDA app. I've also adjusted refresh rates to match between the laptop and external screen, upgraded the RAM, cleaned the fans, and even performed a reset. The issue still occurs occasionally, sometimes worsening when I play videos, open MS Outlook, or use Adobe Illustrator.
Interestingly, the problem is inconsistent: both screens can work well for a while before the lag or black screen happens. When it does, the beep and screen going dark seems to trigger a reset, with the screens turning back on quickly and performance improving afterward.
I’m not sure if this is related to overheating, as the laptop feels cool, the programs aren’t resource-heavy, and the fans operate normally. Disconnecting from the external monitor resolves the issue completely—my laptop runs smoothly afterward.
If anyone has any insights into what might be causing this, I would really appreciate it. I’m quite puzzled.
With thanks.
Create and model the external display?
Check how the external display is powered and whether it has its own drivers.
Examine Reliability History/Monitor and Event Viewer for any error codes, warnings, or relevant events around the times of the issues described.
Begin with Reliability History/Monitor.
A more user-friendly approach may show clearer patterns in the timeline.
