Need advice mounting 43" TV with a 50cm extension on an interior drywall
Hi everyone, I have a 43" LED Smart TV. The wall is an interior drywall partition with standard gauge metal studs and the wall is about 11 cm (\~4.3 inch) thick. I need to use a heavy-duty, full-motion mount with a long extension arm of about 50cm (\~20 inch). I know extending a TV that far out creates a massive lever effect and pull-out force. I came up with 2 options:
Option 1 - Direct mounting with 6 points of contact
I would secure it directly to the wall using 6 points of contact. The TV mount has a mounting surface of 43cm width and 30cm height (17 inch width x 12 inch height ). Because of the stud spacing, only 2 screws (top and bottom middle) would go directly into one metal stud. The other 4 mounting points (left and right sides of the plate) would go only into the drywall using heavy-duty toggle bolts (like Snaptoggles or other better alternatives). Is this configuration strong enough to handle the pull-out force of a 50cm (\~20 inch) extension without buckling the single metal stud or cracking the drywall?
Option 2 - Mounting a backer board first
To distribute the weight across multiple studs, I would use a piece of \~2cm (3/4") thick plywood or melamine board large enough to span across two adjacent metal studs. I would secure this wood board firmly to both studs to create a solid base, and then attach the TV mount directly to the center of it using thick, short wood screws (lag screws) that bite entirely into the wood without going through into the drywall behind it.
Which of these two options do you think is the safest ? Or maybe you guys might know other options.
Thank you !
