The driver hasn't been digitally signed by a verified publisher. The driver might have been changed to include malware that could harm your PC or steal info. In rare cases, legitimate publishers do change drivers after they've been digitally signed, but you should only install an unsigned driver if you got it from a device manufacturer's disc. This package contains the software application that allows users to configure their Dell monitor settings such as Brightness, Contrast and Preset Modes. This application requires Display Data Channel Command Interface (DDC/CI) to work. I can physically rotate my Dell desktop's monitor to a portrait format BUT how do I change the software set-up so that the 'picture' is also in portrait format. (Just changing the physical position leaves everything else iin landscape and thus 90 degrees out.) Answer soon please: my neck is startin. Other PCI device that Windows cannot identify If you tried the above two steps and your Windows Device Manager still contains an Unknown PCI device, likely the device cannot be identified.

Driver updates for Windows 10, along with many devices, such as network adapters, monitors, printers, and video cards, are automatically downloaded and installed through Windows Update. You probably already have the most recent drivers, but if you'd like to manually update or reinstall a driver, here's how:
Update the device driver
In the search box on the taskbar, enter device manager, then select Device Manager.
Select a category to see names of devices, then right-click (or press and hold) the one you’d like to update.
Select Search automatically for updated driver software.
Select Update Driver.
If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.
Reinstall the device driver
In the search box on the taskbar, enter device manager, then select Device Manager.
Right-click (or press and hold) the name of the device, and select Uninstall.
Restart your PC.
Windows will attempt to reinstall the driver.
