FIREPLACE & TV ON THE SAME WALL ??

[Karen Margrave]

Have any of you installed a gas fireplace and had a tv on the same wall above it? I see it done on Houzz, and in magazines all the time, however; how practical is it? Is the TV too high?  Is there too much heat off the fireplace for the TV? (I understand we have to take extra precautions etc. insulating for wiring, etc.) 

It's just for looks, we are in southern California after all!  I'm thinking of one of the linear fireplaces since we're building modern style. Your opinions and experiences are appreciated.
