What is the purpose of video walls?

The main reason people want video walls is to get attention of customers. It’s hard to walk past a video wall without looking at it. There are two kinds of video walls: the big ones and the creative ones.
The reason why people want big video walls, is because it’s big and it’s get attention. See the picture of Media Markt below… Yeah, it’s that big! You can show your logo, offers or video’s on it. People will see it.

The creative ones are actually the fun ones. Because they don’t have a 16/9 resolution. See the pictures of Primera and BP below. The width is bigger than you expect. You can also make a flower formation. People will likely stop and look at it, because it’s quite rare to see it. And ofcourse because it looks awesome.
