Use Your PSP As An External Display
With a simple piece of software you can use your PSP as an external display. The software, which is available to download on their site, allows you to use the PSP as a 960×544 display. The data is sent over compressed and then decompressed for display. Although this sounds like it would slow things down, the video above shows it working nice and smoothly. Currently only 32 bit Windows XP or older is supported.
