Walls – Video Wall Mount in the home

Short answer: As long as you're compliant with the TV/mounting documentation and there aren't significant defects in the studs (e.g. termite damage, water damage, etc) you should be fine.

Longer answer: I did this fairly recently and my advice is as follows...

• Make sure you purchase a TV stand that is rated for the size/weight of your TV. The specs on the site look pretty beefy but don't take any chances. Consult your TV manual for mounting details. Most (if not all) TV manuals will explicitly specify the weight of the TV and what VESA mounting pattern is required.

• Confirm what's included in the mounting kit and what surfaces it's rated for. The mount should explicitly say what its rated for and what's required. Our mounting kit (different brand) came with two sets of screws (1 set for concrete and 1 set for wood).

• Get a mounting kit that supports heavier weights and multiple VESA patterns. If/when you ever upgrade the TV, you don't want to have to replace it. :-)

• Have a friend help. Installation is waaaaaaaaaaaayyyyy easier (and much safer) when multiple people are involved.

• Check to see if the mounting kit lets you make small adjustments AFTER it's mounted. After setting (and re-setting) our TV mount several times, I later learned that it had the ability to make slight tilt modifications while mounted. D'oh! This saves gobs of time and is an awesome feature.

What's the least intrusive way to find out what's in a wall?

How do I run wires for a wall-mount flatscreen TV?

No... those expanding bolts aren't going to do the job, period. There are several reasons but suffice it to say your TV will find up on the floor. Toggle bolts of some variety are the preferred way to do it... it's hard to believe that no one in a city the size of yours has them or something more suitable. What you need is something that will spread the weight of your TV over a wide enough surface area and not be dependent on resisting withdrawal through the sheetrock, as the ones you pictured are. You said you can't find the studs... how have you tried? Is your home typical studs with sheetrock over? If they are metal studs that might be why you're having so much trouble. But don't use what you have pictured, they are not suitable. Let me know your answers to the above and I'm sure we can figure this out.
