HP Spectre x360 14 Intel Arc A370M Not Detected Windows 11

The Intel Arc A370M discrete GPU on your HP Spectre x360 14 does not appear in Device Manager under Display Adapters – only Intel Iris Xe or Intel Arc integrated graphics is listed. Applications use only integrated graphics and performance in GPU-accelerated tasks is much lower than expected from an Arc A370M.

This guide covers Intel Arc A370M driver installation, DDU cleanup, and Intel Arc Control setup to get the discrete GPU detected and running on the HP Spectre x360 14 in Windows 11.

“Arc A370M was completely missing from Device Manager on my Spectre x360 14. Only integrated graphics showed. HP Support Arc driver fixed it and now both GPUs appear.” – Fatin, digital designer from Shah Alam

Why Intel Arc A370M Is Not Detected on HP Spectre x360 14

The HP Spectre x360 14 uses Intel Dynamic Tuning Technology to manage both Intel Arc integrated graphics (in the Core Ultra processor) and the discrete Arc A370M. When the Intel Arc driver is missing or at the wrong version, the driver stack for the discrete Arc GPU cannot initialize, leaving only the integrated graphics visible. Both GPUs share the Intel Arc driver family but require the HP-specific configuration to enumerate the discrete card correctly.

• Intel Arc A370M driver missing – discrete GPU not enumerated in Device Manager
• Intel DSA (Driver Support Assistant) installed incompatible Arc driver version for HP Spectre
• Driver conflict between integrated Arc and discrete Arc A370M after Windows 11 update
• Intel Arc A370M appears as unknown PCI device in Other devices category

Fix 1 – Clean Install Intel Arc Driver with DDU

Boot to Safe Mode (Shift + Restart – Troubleshoot – Advanced – Startup Settings – F4). Run DDU, select GPU and Intel, click Clean and restart. After normal boot, go to support.hp.com/us-en/drivers, enter the Spectre x360 14 service tag, and download the Intel Arc Graphics driver under Display – Video. This HP-qualified package correctly configures both the integrated Arc and discrete Arc A370M driver stack.

Fix 2 – Check Device Manager for Unknown PCI Device

Open Device Manager and look under Other devices or PCI Express devices for an unknown device. Right-click it and select Properties – Details – Hardware IDs. If the device ID starts with VEN_8086 and DEV_56A0 or similar Arc discrete IDs, this is the Arc A370M awaiting a driver. Select Update driver and browse to the HP Intel Arc driver package folder extracted from the HP download.

Verify Intel Arc Control After Installation

After successful Arc driver installation, open Intel Arc Control (installed automatically with the driver). The system section should show Intel Core Ultra integrated Arc graphics AND Intel Arc A370M as separate GPU entries. If only one appears, the driver installation was incomplete. Reinstall the HP Arc driver package after another DDU cleanup.

Fix 3 – Update HP BIOS

Open HP Support Assistant and check for BIOS updates for the Spectre x360 14. HP BIOS updates include Intel Arc firmware improvements that improve discrete GPU detection and initialization during boot. BIOS updates are a critical step when Arc A370M is not detected even after clean driver installation, as older BIOS firmware may not correctly initialize the discrete GPU PCIe link.

Fix 4 – Configure GPU Switching in HP Command Center

Open HP Command Center. Look for Display or GPU settings. Some HP Spectre x360 14 configurations include a GPU switching option between Hybrid and Discrete modes. If set to Hybrid, the Arc A370M is only used when applications request high-performance GPU. In Discrete mode, the A370M is always active. Switch to Hybrid and back again to reinitialize the GPU switching service that may have failed to detect the discrete card.

Frequently Asked Questions

Why is Intel Arc A370M not detected on HP Spectre x360 14?

Intel Arc driver is missing or at incompatible version. DDU clean remove all Intel graphics drivers and reinstall the HP-qualified Intel Arc driver from HP Support.

How do I reinstall Intel Arc driver on HP Spectre x360 14?

Safe Mode DDU clean install, then download Intel Arc driver from HP Support for Spectre x360 14. Avoid Intel DSA on HP laptops.

What Intel Arc GPU does HP Spectre x360 14 have?

Intel Arc A370M (4GB GDDR6) discrete GPU with Intel Core Ultra 7 integrated Arc graphics.

Does HP Spectre x360 14 support Intel Arc Control?

Yes – Intel Arc Control installs with the driver and shows both integrated and discrete Arc A370M for performance monitoring and game profile management.

Conclusion

Intel Arc A370M not detected on HP Spectre x360 14 in Windows 11 is resolved by DDU clean removal of all Intel graphics drivers in Safe Mode, followed by installing the HP-qualified Intel Arc driver from HP Support. Updating HP BIOS ensures correct PCIe initialization for the discrete Arc A370M. Intel Arc Control confirms both integrated and discrete GPUs are correctly detected after installation.
