That is what the customer thinks when they see an LCD in your business. I have no doubt about this, because I make it a point to observe people when an LCD is present in a retail business. Most people ignore them. Even in lobbies and waiting rooms, usually they are ignored.
That is because someone is failing to make them relevant or useful to the customer!
Dick Morris is famous for his line to Bill Clinton when running for the presidency: "It's the economy stupid!"
Well, I have a modified take on that, which is the key to selling and buying digital signage, whether DOOH or in-house.
It's not the hardware; IT'S THE CONTENT AND USAGE!
Technological hardware will never achieve anything or solve anything or improve anything if you don't use it effectively. This is what's wrong with so many lcd installations. We just pitched a company who has edgy, hip, imagery, product, and branding, but they haven't even integrated their retail store lcd deployment, and they aren't using them for messaging.
LCDs as a medium have to work that much harder to overcome the unspoken but manifest bias in customer's minds that they are just TVs (and not even as good as the one at home.) Much better to jolt that viewer with a Window Video System (WVS) and then message them into doing what you want them to do. Ideally that should be something sales-related, or at the very least, something trackable. But always lean toward selling. Otherwise you run the risk of lapsing into that grey area where business justifications start to veer away from dollars, sense, and profit.
