Which HP all-in-one system allows the display to be mounted in portrait or landscape mode?

The HP Engage One Pro is the all-in-one system that allows the display to be mounted in either

portrait or landscape mode. This flexibility is particularly useful in various retail and hospitality

settings where different orientations may be needed for different applications. The ability to switch

between portrait and landscape modes allows for better customization of the user interface and

improves the overall user experience. Reference for this capability can be found in the product

datasheets and user manuals for the HP Engage One Pro.
