A:AnswerIf your 65" TV has a standard VESA mount back, it should work. We recently mounted an LG 65" (32 lb) OLED TV to this mount and it works really well.
A:AnswerYes. The stand has height adjustment. You can adjust the height when hanging the tv on the mount. I currently have 6 inches between the tv and base.
A:AnswerThere is seven slots where you can choose to lower how you can hang out I will send photos that will display it being hung from the second to last slot hopefully this is helpful to you.
A:AnswerThis stand should fit your 48" Sony without a problem. It is advertised as a universal mount, so the associates at Best Buy have sold this stand with confdience. I bought one for my LG OLED TV and it was perfect.
