HDMI cables are very large and can prevent a keep equipment close to the wall or to the bottom of a mobile. For that there are these adaptors 90 degrees. Ordered two different types.
One of the adapters have the male side slightly higher while in another is greater the female side.
Serves for input or HDMI output. You must put the male side in the TV and connect the cable into the female side.
Detail of the upper side of the adapter.
The other adapter is stockier.
My ps3 is right back there on holder thanks to these adaptors.
There are TVs on the wall bracket in which you cannot connect anything without this adapter.
Great product, works without bad contact. I leave below link for products:
