HP ZBook Studio 16 G10 HDMI No Signal Fix

HP ZBook Studio 16 G10 · Core i9-13900H · NVIDIA RTX A · Windows 11 · HDMI output

When an external monitor connected to the HP ZBook Studio 16 G10 HDMI port shows no signal, the cause is usually a driver configuration issue, an incorrect output mode selection, or a cable or display compatibility problem. Follow the steps below to identify and fix the root cause.

Fix 1 — Update NVIDIA and Intel display drivers

Download the latest NVIDIA RTX A-series driver for mobile workstations from the NVIDIA website. Also update the Intel display driver from HP Support for the ZBook Studio 16 G10. A mismatch or corrupted driver is the most common cause of HDMI no-signal issues on dual-GPU workstation laptops.

Fix 2 — Press Win + P to set display mode

Press Win + P and select Extend or Duplicate. The HDMI output may default to PC screen only mode after a driver update, which disables the external monitor output entirely even when a cable is connected.

Fix 3 — Test with a different HDMI cable and monitor

Swap the HDMI cable for a known-working one, ideally HDMI 2.0 or 2.1. Also test with a different external monitor or TV. A faulty HDMI cable is often overlooked and can cause a clean no-signal result even on a working laptop port.

Fix 4 — Check the GPU selection in NVIDIA Control Panel

Open NVIDIA Control Panel → Display → Set up multiple displays. If the external monitor appears but is not enabled, click on it and select Use this display. On workstation models, HDMI is sometimes routed through the Intel iGPU and may require adjusting the GPU assignment in 3D Settings.

Fix 5 — Update the BIOS

Install the latest BIOS from HP Support for the ZBook Studio 16 G10. HP has released BIOS updates for this model that address HDMI port initialization issues and improve compatibility with 4K displays at 60 Hz and higher refresh rates.

Faizal, Cyberjaya: “My ZBook Studio showed no signal on the external monitor after a Windows update. Updating the NVIDIA driver and pressing Win+P to switch to Extend mode fixed it immediately.”

Frequently Asked Questions

Which GPU drives the HDMI port on the HP ZBook Studio 16 G10?

On most HP ZBook Studio 16 G10 configurations, the HDMI port is connected to both the NVIDIA RTX A-series GPU and the Intel integrated graphics. The active GPU driving the output depends on the Optimus setting in NVIDIA Control Panel and whether hybrid mode is enabled in the BIOS.

Does the HP ZBook Studio 16 G10 support 4K 60Hz over HDMI?

Yes. The ZBook Studio 16 G10 HDMI 2.1 port supports 4K resolution at 60 Hz and higher with a compatible display. Use a high-speed HDMI 2.1 cable to ensure the bandwidth is available for 4K HDR output.

Can I use both HDMI and USB-C displays simultaneously?

Yes. The ZBook Studio 16 G10 supports multiple external displays simultaneously using a combination of the HDMI port and Thunderbolt 4 USB-C ports. The exact configuration limit depends on the specific GPU model in your unit.

Why does the external monitor show as not detected in Display Settings?

In Settings → System → Display, scroll down and click Detect. If the monitor is still not found, try a different HDMI port or cable, and verify the monitor is powered on and set to the HDMI input channel.
