HP Spectre x360 16 — HDMI No Signal Fix
Follow each step in order until HDMI video output is restored.
The HP Spectre x360 16 outputs no signal over HDMI most commonly because the HDMI port is configured to route through the Intel iGPU while the connected display expects a full-bandwidth signal, or because the Intel or NVIDIA display driver needs an update. The i7-13700H model has both Intel Iris Xe and NVIDIA GeForce RTX graphics. HDMI output can route through either GPU depending on the Optimus configuration.
Verify HDMI Cable and Display Input Start here
Confirm the display is set to the correct HDMI input channel using the monitor OSD (on-screen display) buttons. Confirm the cable is HDMI 2.0 or later — older HDMI 1.4 cables cannot carry the 4K 60Hz signal from the HP Spectre x360 16 full-resolution panel output. Try a different HDMI cable and a different HDMI input port on the monitor if available before proceeding to driver fixes.
Detect Display in Windows Settings
Open Settings → System → Display and scroll down to click Detect. Windows should enumerate the HDMI-connected display as a second monitor. If it detects the monitor but it remains black, right-click the desktop and select Display settings, then change the Multiple displays dropdown from Duplicate to Extend. A duplicate display configuration sometimes fails to output signal to monitors that use different refresh rates or resolutions than the laptop panel.
Update Intel and NVIDIA Display Drivers
Open Device Manager → Display adapters. Update both the Intel Iris Xe Graphics and the NVIDIA GeForce RTX drivers. For the HP Spectre x360 16 (Model 16-f2000), download HP-certified graphics drivers from the HP Support page to ensure the Optimus switching behavior is correctly calibrated for the specific panel on the Spectre x360 16. Generic NVIDIA drivers may not handle the Optimus HDMI routing correctly on this model.
Force HDMI Through NVIDIA GPU via NVIDIA Control Panel
Open NVIDIA Control Panel → 3D Settings → Manage 3D settings → Global Settings and set the Preferred graphics processor to High-performance NVIDIA processor. Also check NVIDIA Control Panel → Display → Set up multiple displays to confirm the HDMI port is mapped to the NVIDIA GPU. On the Spectre x360 16, routing HDMI through the Intel iGPU can cause a no-signal condition on some monitors because of EDID compatibility issues with the Iris Xe output at higher resolutions.
Update HP BIOS via HP Support Assistant
Open HP Support Assistant and check for BIOS updates for the Spectre x360 16-f2000. HP has released BIOS updates that improve HDMI port EDID negotiation and Optimus mode switching on the i7-13700H platform. An outdated BIOS can prevent the HDMI port from correctly advertising its capabilities to the connected display, resulting in a no-signal response even when the cable and GPU are working correctly.
I diagnosed this on an HP Spectre x360 16 where HDMI showed no signal on a 4K monitor. The issue was the Intel iGPU handling HDMI at a resolution the monitor could not negotiate. Setting NVIDIA as the preferred GPU in NVIDIA Control Panel forced HDMI through the RTX GPU and the monitor came on immediately.
Per Hafizuddin Razali, graphic designer using the Spectre x360 16 with an external display: “The Spectre x360 HDMI no signal was fixed by selecting NVIDIA as the display GPU in the NVIDIA Control Panel. The Intel GPU was routing HDMI and the monitor just did not accept the signal.”
Frequently Asked Questions
Why does the HP Spectre x360 16 HDMI show no signal?
The most common causes are the Intel iGPU handling HDMI output with an incompatible signal for the connected monitor, an outdated graphics driver, or an HDMI cable that cannot carry the resolution being output. Check the NVIDIA Control Panel to confirm HDMI is routed through the NVIDIA GPU, and update HP-certified display drivers from HP Support.
How do I force HDMI through the NVIDIA GPU on HP Spectre x360 16?
Open NVIDIA Control Panel, go to 3D Settings, Manage 3D Settings, Global Settings, and set Preferred graphics processor to High-performance NVIDIA processor. Also check NVIDIA Control Panel, Display, Set up multiple displays to confirm the HDMI output is assigned to the NVIDIA adapter.
Does HDMI cable quality matter for the HP Spectre x360 16?
Yes. HDMI 1.4 cables are limited to 4K at 30Hz. The Spectre x360 16 HDMI 2.0 port outputs up to 4K at 60Hz. Use an HDMI 2.0 certified cable to avoid signal negotiation failures at higher resolutions. Always try a different cable as a first diagnostic step before driver or BIOS changes.
Can a BIOS update fix HDMI no signal on HP Spectre x360?
Yes. HP BIOS updates include HDMI EDID negotiation fixes that affect how the HDMI port advertises its capabilities to connected monitors. If signal issues persist after driver updates and NVIDIA GPU routing, install the latest BIOS from HP Support Assistant for the Spectre x360 16-f2000.
Conclusion
HDMI no signal on the HP Spectre x360 16 i7-13700H is most often caused by the Intel iGPU handling HDMI with an incompatible signal for the monitor. Force HDMI through the NVIDIA GPU in NVIDIA Control Panel and update the HP-certified display drivers from HP Support. Update the BIOS via HP Support Assistant for EDID fixes that affect HDMI negotiation on the i7-13700H Optimus platform.
