11W brethren.  I am tasked with finding an buying a new TV for our addition's living room, which will hang above the fireplace and sit under a 12 foot vaulted ceiling.  The hearth is 8 feet wide, so there are no size limitations.  I am looking in the 65-80 inch range.  Have any of you bought a TV recently and would be willing to help with any tips you picked up during your own shopping experience?  Any help would be appreciated.
