A:Answer Yes, I have an LG 55OLED just bought and had Installed above Fireplace. Its beneficial to have the Tilt Model. The main thing to consider is space above & below the TV DIMMs. I have about 5" Above, and 2"Below - this is Important because the Installers Need The Upper Space to HANG the TV (they need to Lift it on to the Bracket), pretty sure you can get away with 4" though.
I originally wanted the 65"LG and couldn't get it installed with only a 4" Total Avail Space -Top and Bottom.
The LG OLED's are the Best Quality Pic Avail Today. Close to viewing Lifelike Pic's.
