HP Pavilion HDMI Not Working on Windows 11: Display Driver Fix

HP Pavilion HDMI output not working on Windows 11? The connected monitor shows No Signal or the TV does not detect the laptop at all. This is usually caused by the Intel or AMD display driver not recognizing the HDMI port, or Windows 11 not configuring the second display correctly. This guide covers the complete fix.

Why HP Pavilion HDMI Output Fails on Windows 11

The HDMI port on an HP Pavilion is routed through the display driver — it is not a standalone port. If the display driver has an issue, the HDMI output fails completely. Common causes:

• Outdated or corrupted Intel HD / UHD Graphics driver — the HDMI port is controlled by the integrated GPU in most HP Pavilion models
• Windows 11 projection setting not configured — the display is present but not shown because Extend or Duplicate mode is not selected
• HDMI cable or port issue — easy to eliminate by testing with a different cable or TV
• Display driver crashed — no output until the driver restarts or the machine reboots

Quick Test First

Press Windows + P to open the Project panel. Choose Duplicate or Extend. If the monitor lights up, the driver is fine and just needs the display mode set. If nothing happens, proceed with the driver fix below.

Fix HP Pavilion HDMI by Updating Display Driver

Step 1: Identify Your GPU

Open Device Manager → Display Adapters. Most HP Pavilion models use Intel UHD Graphics (integrated) or a combination of Intel + NVIDIA/AMD for discrete GPU models. The HDMI port on HP Pavilion 15 goes through the Intel integrated GPU by default, even if a discrete GPU is installed.

Step 2: Download Intel Graphics Driver

Go to Intel’s Arc and Iris Xe Graphics driver page and download the latest driver for your Intel GPU generation. Alternatively, use Intel Driver and Support Assistant which auto-detects the correct driver.

Step 3: Clean Install the Driver

Run the Intel Graphics installer. Choose Custom Installation and check Perform Clean Installation if available. This removes old driver entries before installing fresh. After install, reboot and test HDMI again.

Other Fixes for HP Pavilion HDMI No Signal

Disable Discrete GPU HDMI Routing (if applicable)

On HP Pavilion models with a discrete NVIDIA GPU, the HDMI may be routed through NVIDIA Optimus. If NVIDIA drivers are missing or broken, HDMI fails. Open NVIDIA Control Panel → Manage 3D Settings → Global Settings → Preferred Graphics Processor → set to Integrated Graphics. Test HDMI. If it works, reinstall the NVIDIA driver.

Registry Fix for Display Output

If the display driver is installed but HDMI output stays dark, check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video. Each subkey represents a display adapter. Inside each, look for Service — it should point to the Intel or NVIDIA driver, not a generic BasicDisplay. If BasicDisplay appears, the display driver is not loading properly — reinstall it.

Per Sarah K., who is a Graphic Designer using an HP Pavilion 15: “My second monitor via HDMI went black after a Windows 11 update. Pressing Win + P and selecting Extend was all it took — the display was there, just not activated.”

Frequently Asked Questions

Why does HP Pavilion HDMI show no signal on TV?

Either the display driver is outdated, the TV input is on the wrong source, or Windows is not sending output to the HDMI port. Press Win + P, select Duplicate or Extend, and check TV input source.

Does HP Pavilion HDMI use Intel or NVIDIA GPU?

On most HP Pavilion models, HDMI goes through the Intel integrated GPU. On gaming models with discrete NVIDIA GPU, HDMI may go through NVIDIA. Check Display Adapters in Device Manager to confirm.

My HP Pavilion HDMI worked before — why did it stop after Windows 11 update?

Windows 11 updates sometimes reset the display driver or change the default projection mode. Press Win + P and re-select your preferred display mode. If that does not work, reinstall the Intel Graphics driver.

Can a bad HDMI cable cause no signal?

Yes. Test with a different HDMI cable. Also try a different HDMI port on your monitor or TV. Damaged cables are a common but overlooked cause of no signal.

Conclusion

HP Pavilion HDMI not working on Windows 11 is usually fixed by pressing Win + P to activate the display output, or by reinstalling the Intel UHD Graphics driver from Intel’s site. If your HP Pavilion has a discrete NVIDIA GPU, check NVIDIA Optimus settings as well. The HDMI hardware itself rarely fails — the issue is almost always software or settings.
