"pdihwctl.sys" is a kernel driver in Windows operating systems for screen rotation functionality and was developed by Portrait Displays, Inc. The file provides options to rotate the PC's display and accepts user input for rotation settings. It is often bundled with video card drivers for brands like nVIDIA and ATI, even though some versions of drivers have their own rotation settings and options. Portrait Displays, Inc. started in 1993 and earlier in their business structure, they began providing rotatable monitors and software for them for Macintosh when they acquired the product line from Radius Corporation. Eventually, they halted production and focused on their leading software known as Pivot. Now, the company provides advanced imaging software for OEM applications.
