I've read so many forums and advice pages about this but have seen nothing definitive!
I have a 23kg 55" tv and a full motion mount that claims it can hold 40kg+
I think my walls are plasterboard with studs but I'm not 100% certain... If I can confirm, through drilling little test holes, that there are studs are either or both of the following options ok:
1) if studs align perfectly with tv mount then just drill into wooden studs and mount on them with 4 x corner holes of tv mount, then the 2 middle holes of tv mount use heavy duty gripit plasterboard fixings.
2) if studs don't align, or just anyway, use something like 18mm ply/mdf to span all available studs behind tv, fix that in with numerous screws into wooden studs, then screw tv mount into the ply. < If I use this option should I go all the way through wood and plasterboard with the tv mount fixings or not?
Help hugely appreciated. I just want to avoid having to cut out the whole wall and but battens or additional studs in then replastering because that is waaay outside of my experience level. Thanks
