Screen Display Issue with HP Omen: Multiple Split Bars on Screen

[berkerb]

Hello HP Support Team,

I am experiencing a recurring screen issue with my HP Omen Laptop 17-CK2000NT. The display intermittently splits into multiple horizontal bars, as shown in the attached image. This issue persists even after performing a clean installation of Windows 11.

Here are the troubleshooting steps I have already taken:

1. Reinstalled Windows 11 from scratch, but the display issue remains.
2. Updated the graphics drivers using both Windows Update and the NVIDIA official website.
3. Checked display settings and reset them to default values.
4. Connected the laptop to an external monitor, where the display appears normal, indicating that the issue may be specific to the laptop’s built-in screen.

The laptop’s specifications are as follows:

• Model: HP Omen Laptop 17-CK2000NT
• Processor: Intel Core i9-13900HX
• GPU: 16GB GeForce RTX 4090
• RAM: 32GB
• Display: 17.3-inch QHD

I would appreciate any guidance on resolving this issue. Is there a possibility of a hardware malfunction, or are there additional software/driver adjustments I can try?

Thank you for your assistance.

Kind regards,

Berker Baydan

Hi @berkerb,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

Based on your description and troubleshooting steps, the issue appears to be hardware-related, specifically with the built-in display panel or its internal connections. Here's why.

1. External Monitor Works Normally: When the display is fine on an external monitor, it suggests the GPU and drivers are functioning correctly.
2. Persistence After Clean Windows Installation: Since the problem persists after reinstalling the OS, it's unlikely to be software-related.

Next Steps to Diagnose and Resolve:

1. Perform a Built-in Diagnostics Test:

• Restart your laptop and press F2 repeatedly to enter the HP Hardware Diagnostics menu.
• Select Component Tests > Display Test to check for any errors with the built-in screen.
• Note down any error codes and report them to HP Support.

2. Check for Firmware Updates:

• Visit the HP Support website and search for your laptop's model.
• Download and install any available BIOS or firmware updates for your system.

3. Inspect the Display Connection:

• If you're comfortable with hardware, inspect the ribbon cable connecting the display panel to the motherboard. A loose or damaged connection can cause such issues.
• If unsure, have an HP-certified technician inspect it.

4. Reset the GPU Settings:

• Open the NVIDIA Control Panel > Manage 3D Settings > Restore to Default.
• Ensure the laptop is using the NVIDIA GPU for applications and not switching to integrated graphics (check Display Adapter Settings).

I hope this helps.

Take care and have a good day.
