Not just media center.

I wouldn't need to go through so much hassle just for media casting. I have tested MHL and Miracast.
I'm trying to become as portable as possible. I personally find that 8" to 10" is the sweet spot for maximum portability, but most such devices are tablets geared towards media consumption.

I can access corporate email and Excel, Word, Powerpoint on my Tab S but it's cumbersome to perform updates or type long emails. I have tried Miracast and find that there is a 0.5 second lag that actually breaks your concentration when you want to write / update something.

MHL does not have the lag but I am left with a bluetooth mouse and keyboard. This introduces its own set of problems when the bluetooth devices go to sleep, there is a lag to wake them up again.

Even then, MHL is a phone-only solution. As I posted earlier, I had almost gotten the combined MHL + OTG dongle until I came across Displaylink.

The pics of CoC were only for initial testing of connectivity, to show it works.

The upside is that by using a combo OTG + Charging extension, I can use:
1. Logitech K400R wireless combo keyboard + mouse
2. the Displaylink dock
3. CHARGE MY PHONE AT THE SAME TIME.

You can see this in the pic showing the Logitech Unifying receiver.

All day fully portable computing.

An additional benefit is that this dock will also connect to any Win 8.1 and/or Win 10 tablet without needing to get pricey bluetooth keyboard docks.
