This is an educational topic that I have to teach quite often to prospects and newbies to the digital signage market. People see cheap LCD screens at Best Buy and think that they should integrate that quality into their retail location. A commercial grade screen costs more and people often think too shortsightedly at the initial cost, not thinking about the total cost of ownership. Like replacing that screen in a matter of months because you ran it 24 hours a day, burning in the image and frying your motherboards. And your limited consumer warranty will not cover you.
A commercial screen will often come with a 3 year warranty, is made for 20+ hours of commercial use with fans, lower overall power consumption, and in some cases, technology to prevent burn in (image retention). Many other reasons exist too, and so it was good to see our partner Samsung sponsor a white paper on the topic. It does a decent job of explaining why the initial up front cost will save you much heartache and money in the near future.
