Going home this afternoon to work on the living room
The new wall mount goes right across both the wall plate for the HDMI cable and the electrical outlet
Moved the electrical outlet up to clear the mount and turned it horizontal. Blocking for the old wall mount had to be cut out to accommodate the relocation. The existing holes for the HDMI cable and center channel speaker wiring will be abandoned and patched as they are being relocated as well. The larger hole is going to be a recess for the stupid proprietary box separate from the TV that has all of the HDMI inputs.
