Mounted a TCL 65" tv on wall. my first Television larger that 40 inch. The Mount is holding it but when I pull out fromwall to possibly get an angle with the mount of the TV it wants to move out of position and angle down.  I figure the nuts from the factory setting are no tight enough to hold out from the wall this size of Television. I believe mine weighs about 50LBS.  It works well only when I have pushed straight viewing from wall mount.
