HDMI Adapter for Galaxy tab2 10.1

Got this adapter about 3 months ago, plugged it in my tablet, hdmi cable into TV and plugged the tablet into AC adapter. Worked like a charm. For next 2 - 3 weeks we watched PLEX videos each night while in bed. I then needed my tablet elsewhere and disconnected it from the adapter.

Recently, I hooked it up again but now all the videos, regardless of the player, stutter making them impossible to watch. I tried new hdmi cable and/or connecting the adapter/tablet to another TV in the house with the same dismal results. Then I noticed something strange.

When I touched the screen while a video was playing the player control bar (i.e pause/play buttons) would pop up AND the video went perfectly smooth (audio that was out of synch went back in synch) until the control disappeared off the screen.

As well, simply unplugging the HDMI cable and restarting the video will also eliminate the stuttering.

To sum up, video only stutter when in "full screen" AND the HDMI cable is plugged into the TV.

Sometime between when I disconnected the adapter the 1st time and the present something changed on my tablet. I have no idea what this may be.

Any1 have any idea why these videos would stutter in "full screen" mode but play perfectly well with the control bar visible??

 

No it does not.. I even went as far as removing/stopping as many apps as possible to free as much memory but nothing helped. In PLEX, I can set the streaming rate and even at its lowest (480p) rate the stutter is the same.
