Monitor not detected

[sm123456mait]

Hello HP Community,

I have an HP Victus 16 (Ryzen 7, Windows 11, hybrid AMD/NVIDIA graphics) and am unable to get my external monitor to work via HDMI (and/or USB-C). This issue started recently—previously, both internal and external displays worked, and my TV is sometimes detected, but my PC monitor either shows “no signal” or appears as a gray, disabled “Generic PnP Monitor” in Device Manager.

What I’ve already tried:

• Checked HDMI/USB-C cables, different ports, and confirmed monitors work with other machines.

• Updated Windows 11 to latest version.

• Removed all AMD/NVIDIA graphics and AMD chipset drivers using DDU, then reinstalled latest drivers from official sites.

• Updated BIOS/UEFI to the latest version from HP.

• Tried both current and previous BIOS versions (no difference).

• Set internal display to 1920x1080 @ 60 Hz before connecting external monitor; tested lower/higher refresh rates.

• Power cycled both laptop and monitor, and plugged in monitor before boot.

• “Detect” function in Windows Display Settings, and cycled with Windows + P.

• Disabled AMD Eyefinity and confirmed NVIDIA/AMD control panel settings.

• Uninstalled gray Generic PnP Monitor in Device Manager and performed hardware scan/restart.

• Ran Windows sfc /scannow and DISM repairs (no integrity violations detected).

• HP Support Assistant and hardware diagnostics (no issues found).

• Checked for missing or problematic devices in Device Manager ("requires further installation", missing ACP driver, etc.), and updated AMD chipset drivers.

• Tried alternate output configuration (USB-C → HDMI adapter, same result).

• Monitors work via TV but not standard PC monitor.

• Attempted fresh Windows install (no effect!).

Context:

• Laptop: HP Victus 16 series, Ryzen 7, hybrid AMD/NVIDIA GPU, Windows 11.

• The problem persists across multiple monitors and cables that work on other laptops/desktops.

• System otherwise stable, no crashing or clear GPU failure. Internal display works fine.

@sm123456mait, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

It sounds like you've already gone through a pretty comprehensive list of troubleshooting steps. Given that the problem seems to be isolated to your external monitors (and not cables or the monitors themselves, since they work with other systems), the issue could involve one or more of the following:

Try Disabling One GPU:

Go to Device Manager and disable either the AMD or NVIDIA GPU temporarily. Check if the monitor works after that.

Clean Driver Reinstall:

Completely remove all graphics drivers, then reinstall just the NVIDIA or AMD drivers (not both).

Check in the Graphics Control Panel:

Open the NVIDIA Control Panel or AMD Radeon Settings. Check if the external monitor is detected and adjust settings there.

Force Monitor Detection:

Right-click the desktop > Display Settings > Detect. If it still shows as "Generic PnP Monitor," try adjusting the resolution or refresh rate manually.

Check BIOS Settings:

Go into BIOS and look for settings related to hybrid graphics or PCIe. Disable or adjust these settings if needed.

I hope this helps.

Please feel free to reply here if you have any questions or if you need further clarification on any of the steps. 

Take care and have a good day.

System Model Victus by HP Laptop 16-e0xxx
System Type x64-based PC
Processor AMD Ryzen 7 5800H with Radeon Graphics, 3201 Mhz, 8 Core(s), 16 Logical Processor(s)
BIOS Version/Date AMI F.24, 30-07-2025

SO I tried all the methods you said. I could not do the BIOS thing, as there was apparently no option. I am still facing the same problem. My TV still seamlessly is recongnised but not the external monitor.
