Video output options
As most people have probably already heard, the "MHL" port on the SGS3 isn't compatible with existing MHL accessories or displays (so it isn't really an MHL port then is it). See
this site for more on that.
Sammie has released some over-priced accessories for it, but buying those would reward and re-inforce this move (the only nasty thing the've done on an otherwise brilliant phone) and they would probably become landfill when you get your next phone. Besides, Sammie recently indicated that this port can do more, so I guess that means they will release a second round of video accessories for this phone, making the first round landfill even before you move on to your next phone.
So, if someone really needs video output for their SGS3, what are their options?
Samsung makes a wireless (Wi-Fi) streaming video dongle for the GSIII, but this too appears to be proprietary and possibly just for the GS3. It looks like there are standards coming for wireless streaming, but they aren't here yet (e.g.
Miracast).
Are there other wireless video streaming devices that work with the SGS3?
Even better, though, has any other company created accessories that are compatible with the fake MHL port on the SGS3? The best would be something that worked with the SGS3 and with standards compliant MHL devices and displays (of which there are now > 100), but I don't know if that is possible.
Actually, for some users, something a bit different might work...
DLNA for example, which allows you to play content from your phone on any smart TV. It's not the same as 'video out' for your phone, but I think some poeple are just looking for a way to get media from their phone to their display. And DLNA is very widely supported standard now.
Also, these are low cost Android 4 devices in the form of an HDMI dongle - you plug them directly into your TV:
