A:Answer Actually LG's answer is incorrect. I have two wall mounts, 1 from Lowes, 1 from Best Buy - both fit 300 x 300 but neither will fit the 65UJ7700. This TV has a "bulge" at the bottom of the TV just barely below the bottom holes and therefore severely limits the options. I have yet to find one that works. The wall mount on the LG website that comes up with the search does NOT fit 300 x 300.. And that is the only one customer service at LG could come up with. When I asked her about the instructions that 300 x 300 would not fit, she said she could only read what was on her screen and suggested I call a professional installer. wow. just wow.
