1- Connect an external monitor to the notebook. For instructions on connecting an external monitor, see Connecting a Monitor, Projector, or TV (Windows 10, 8).
2-If the computer screen does not automatically display on the external monitor, press F4 (or the key with this symbol ) until the screen image displays.
3- If an image displays on the external monitor, there might be a graphics driver conflict with the notebook LCD display. With the external monitor connected, go to HP Customer Support to download and install the latest graphics and chipset drivers for your specific computer. If there is an updated BIOS version available, use the steps in Updating the BIOS to install it.
