PSPdisp [Current version: 0.6]

This program package enables the use of a Playstation Portable as an additional monitor in Windows. You can also remotely send keyboard and mouse commands to the PC. The newest version implements sound streaming, too.

PSPdisp is compromised of four components, on Windows a display driver, an usb driver and the interface application which captures the screen, compresses it and sends it over USB or WLAN to the PSP. On the PSP side there is an application that decompresses the frames and displays them.

System Requirements

Download the installer package below and execute it. The installer works for all supported platforms and will install the correct 32 bit or 64 bit drivers.
If you want to manually install the drivers, you can extract the setup files with an unzip tool (like 7zip). This will leave some files in the wrong folder, so this is only recommended if you know what you are doing.

Important! If you uninstall a previous version you have to restart the computer before starting the new setup. Otherwise the new display driver will be uninstalled on the next restart and you have to install it again!

Note that the usb, the display and the SideShow driver are not WHQL certified. Windows will present you with a security warning because of that.
