I was looking for the most affordable and compact bracket for a 21 '' monitor. Perfect for a small table. Just consider the height! Although it is tall, a 13 '' laptop in the open position under the monitor fits only if you install it as high as possible. There is a 15 '' laptop nearby and you have to move it away so as not to touch the monitor when you open it. And I have a monitor with a mount at the very bottom. This means that a monitor with a mount in the middle will hang too low and an open laptop simply won’t fit under it. Especially if the diagonal is more than 21''
