A:AnswerThank you for your inquiry, John021980. Yes, the Insignia™ Full-Motion Wall Mount is designed for TVs ranging from 47" to 90" and extends up to 25.2 inches from the wall. While it provides flexibility for positioning, the ability to rotate a 45-inch TV a full 90 degrees depends on factors such as the mounting arm length and clearance space.

A:AnswerI have a 70" LG connected to mine. But I don't have any trouble with the full motion feature of the mount. When I purchased the TV and wall mount I also purchased the Total Tech Membership. So I was able to have the Geek Squad install mine for free, and they did a great job. I would suggest asking them for help trouble shooting. Even before I purchased my Total Tech Membership they were ALWAYS great about helping me figure out a range of different problems. I'm sorry I couldn't be more help. You may consider the Membership too. It paid for itself in the first computer repair and TV wall mount installation and TV set up.
A:AnswerThis Wall Mount works for most screen sizes between: 47 in. to 90 in. diagonal. (Including 55" and 70"). The maximum TV weight is 130 lbs. (59 kg).
