Highlander is correct, those are the fancy $3 angle plugs from Monoprice. They received mixed reviews but what did I care; for 3 bucks, I was willing to give them a try. They do seem a little flimsy but work fine plus they go well with my fancy $9 HDMI cables.
Which reminds me...the HDMI cables are too stiff. This is the first non-BJC HDMI I have tried.
Which also reminds me...I hate how Panasonic changed the inputs to the side, of the back, of the display. It works for me because the side they are on is towards the closed part of the room but if they were on the other side, you would see every cable. My older Panny had them in the middle which was better.
Which reminds me, maybe I will have a new outlet installed right behind the display to hide the power cable and then run the HDMIs in the wall.
This thread reminds me that I have yet to have any coffee this morning.
Which reminds me that today I am installing flood lights, can lights and the display for the patio.
That reminds me that I have some reports due for work and I shouldn't be on here.
But...that reminds me that I have a few questions left on the way I should hook up the outdoor display.
