I know that one can install command-line linux distros on android. I also know that the screen resolution can be changed. I have a laptop screen with vga input laying around that I was hoping to turn into a small netbook for school with my phone as a processor. However, I have the droid razr m and I can't find (online) any way to output video so I can use the laptop screen. So my question is: How do I output the phone screen to VGA/HDMI as cheaply as possible?

  • You'd probably need to build a transcoder yourself. If the Razr M supports MHL output you might be able to find a commercially available MHL-to-VGA converter. – Dan Hulme Jul 14 '14 at 23:06

  • That doesn't convert to VGA, it's for HDMI, and as I said, it depends on whether the Razr M supports MHL. – Dan Hulme Jul 14 '14 at 23:11
  • Ya hdmi will work for me too – Elliot Gorokhovsky Jul 14 '14 at 23:11

I don't think there is a way to do this with this phone. The Droid Razr M doesn't support MHL, and its Android version is too old to have the feature of mirroring the screen to a Chromecast. You could still use Chromecast to send specific video (i.e. from movie players, presentation apps, or YouTube) to anything that has HDMI input, but not to mirror the whole screen.

Note that the phone's screen itself doesn't use a high-level protocol like VGA or HDMI, so you can't simply take the screen off, cut its ribbon cable, and wire a VGA screen in its place.
