Thanks for the interest and questions.

This is something I pulled off the internet:

"Check your TV's owner's manual for mounting guidelines. Most TVs are compatible with brackets that follow VESA (Video Electronics Standards Association) standards. You'll see the word "VESA" followed by a number, which tells you how far apart the holes on the bracket or TV are in millimeters. For example, VESA 75 means that there are 4 holes in a square, and each side of the square is 75mm long. VESA 100/200 means that the holes are in a rectangle, with two sides measuring 100mm and two sides measuring 200mm. You should be able to find that information in the owner's manual, or you can measure the holes yourself to determine which VESA standard fits your TV. Many mounting brackets are compatible with more than one VESA standard, so finding one to fit your TV won't be difficult."

The horizontal mounting brackets on this TV stand are 21" long and the vertical brackets are 17", and as you can see, they have bored slots throughout. The base itself is not adjustable in height. I've attached additional images. I hope this helps.

Question: I received this package yesterday. Curious whether it's possible to use the brackets you provide in the package for 200x200 VESA TVs or is a separate mounting bracket necessary to attach to the stands brackets?
