I have Samsung Galaxy S3. I connect my phone to 29 inch monitor using HML + HDMI wires. Also I connect it to Apple bluetooth keyboard and magic mouse. I get a very nice experience of Desktop. However S3 has maximum resolution of 1280x720 which does not give a nice look on big monitors.

I have following questions:

  • Can I extend my monitor screen from mobile screen so I can drag and drop apps from one to another?
  • Can I change resolution of apps running on my monitor to higher than 1280x720.


Note: External monitor does not have touch functionality.

  • 1
    I doubt that the graphics chip in the S3 is able to produce higher resolutions.

Having a different external display was one of the new features with Jelly Bean 4.2 You will need a siutable update for your S3 to stand a chance. What level of support you will get then is still in doubt depending upon the real hardware capabilities and what support Samsung put in.

  • Great. I have seen 4.2 documentation. When I had asked this question, 4.2 was not released yet. Do you have real life experience on this feature?
