Frequently Asked Questions

Is it safe to wall mount large TVs?

Choosing a wall mount that is compatible with your TV size is important. Since TV mounts have to lift a significant amount of weight, you must consider a durable one. 

Is it safe to mount a TV without studs?

Most of them are designed for drywall but it still requires you to install studs for a more secure experience.

Without studs, your TV will hang on the wall just like a picture frame which can fall anytime, and watching TV can be uncomfortable.

Where can mounts fit?

Some can fit above the fireplace mantel, movie theater, outdoor, and indoor lounge. Anywhere you watch TV, you can mount it. 

Is hardware included in the mount kit?

Yes, they should have the following hardware:

  • Cables 
  • Cords
  • Studs
  • Screws 
  • Washers
  • Spacers

What type of TV mount is the best?

We suggest that you choose one that is compatible with the size, weight, and height of your TV. This is because they are specifically designed to support the weight of your television.

What if your wall has no studs for the mount?

It is ideal to use studs but if there are no studs available then you can use the hollow-wall anchors, which can help attach the TV to your wall.

The hollow-wall anchors come in huge varieties and are readily available for any size and style of the wall. 

Can a TV be too heavy for a wall mount?

TV size and weights are directly linked to each other, if the size is large then ultimately it will be heavy. There are VESA standards for checking the capacity of your TV size with the TV mount’s capacity.

Can I mount my TV myself?

Yes, you can mount your TV yourself. However, we advise you to read the manual before you get started with the process.
