We were just talking about the state of custom ROM hacking on Windows Phone 7, including some of the reasons users seek out that kind of modified code. One compelling reason to do so is the desire to get features which Microsoft or the phone’s manufacturer left out. That just what we’re looking at today, on news of an interesting modification that can add video out capabilities to a WP7 handset.
How can you do video out without a hardware jack in place? By co-opting an existing output, obviously. This hack routes screen data over the phone’s USB connector, delivering it to an attached PC. That represents just one of the many limitations of this system: it doesn’t do standard HDMI for connection directly to a monitor, requiring you to run client software on a PC in order to view the stream.
Other limitations with this method include how it’s incompatible with PC syncing through Zune, requiring you to reset the phone to re-enable standard USB connectivity. You’ll also notice your phone’s refresh rate take a hit, as the system struggles to push as much data as possible over USB. And, of course, since we’re talking about hacked ROMs, you’ll need a phone with custom ROMs available for it.
All those caveats aside, it’s impressive that this even works at all, and shows just how resourceful smartphone hackers can be. If you’re curious in giving things a spin, full details on what you’ll need to get both your phone and PC set up and ready are available through the source link below.
