Compared with other Kindle models, Amazon's is gargantuan. Its 9.7-inch E Ink screen provides ample space for reading books and viewing graphs and images. But what if you could use all of those E Ink pixels for something more creative, such as displaying your Windows desktop As it turns out, with a few simple tricks you can use the Kindle DX as a computer display that can show anything your usual monitor can show.

In this guide I'll explain how to do it. First, however, some credit where credit is due: People originally showcased this method on TinyApps.org, demonstrating the procedure on a Mac. After working with those folks, I was easily able to apply it to |Windows 7| as well.

Start by connecting the Kindle DX to your computer and waiting for |Windows| to mount it as a USB storage device (this should happen automatically after a moment). Next, from Kindle-jailbreak-0.10.N.zip, extract the file called update_jailbreak_0.10.N_dxg_install.bin. Place this file in the root of your Kindle (not in the documents folder).
