It's quite peculiar, but there's no documented way for any user to output video from their Windows Phone to an external display (television, monitor, anything else with a screen). We say 'documented' because Windows Phone actually does support video-out, so long as you work for Microsoft. At numerous events where Microsoft has demoed the latest and greatest in the world of Windows Phone, we've always seen presenters plug a USB cable into their phones and magically the video is output!
While it may forever remain a mystery as to why Microsoft didn't bless everyday users with this functionality, there's been a quiet movement to unearth the functionality. Developers marsrogers has been spearheading the project on XDA-Developers since November 2011, and we've been keeping an eye on their findings since the thread was first published. Thankfully marsrogers has been very frequent in updating the post with the latest progress, but for a long time it appeared the project would go nowhere.
That is until a few days ago, when marsrogers shared the image above. It looks like he's reached a breakthrough, after obtaining a key ingredient from a helpful source who sent a copy of an original build 7003 ROM from the LG Panther (one of the earliest prototypes of a Windows Phone 7 device). In simple terms, the best way marsrogers could find the files needed in an accessible way was from prototype software. And as evidenced by the photo shared with the world, it has made video-out possible on a Windows Phone 7 device.
There is a caveat to all of this, and a big one: it may not go public. The reason being that a source marsrogers considers to be "quite trustful" has informed him that Windows Phone 8 will include video-out functionality. Apparently you will be able to output your phone's screen, even via Remote Desktop in Windows.
Video-out is possible in Windows Phone 7, but the discovery just came at an awkward transition time. So that's that we suppose. For more on the project, including insight into how the breakthrough was possible, visit the source link below.
