It is necessary to review with Hewlett Packard which the maximum resolution on your laptop is. Now, if your laptop has switchable graphics, it is possible to disable Intel graphics in the BIOS, but if it has Hybrid graphics, it is necessary to use both drivers at the same time.
Your pc manufacturer use customized drivers, so it is necessary to install the drivers available at their website. Make sure, you have the latest BIOS and chipset.
