David: Welcome to another edition of Tech Talks with Konnectus.  Today our topic is going to be LCD screens.  A question we are asked all the time from clients is "Can we use residential grade, or should we use commercial grade LCD screens in our projects?" What are the differences, Jonathan, between the two?

Jonathan: Look, there's two main differences between residential and commercial grade screens.  The big one is the warranty.  Residential screens have a one-year warranty, and a little known fact is that the warranty isn't valid for a commercial environment.  So, as soon as you take a residential screen to a commercial environment, the warranty is void.  Now commercial screens, on the other hand, have a standard three-year warranty, and you can use those in commercial environments.  The second big differentiator is the build quality.  The commercial screens are built with superior materials and components because they are designed to operate for long periods of time, and in harsher environments.

David: So Jonathan, is there ever an application in commercial environments where residential screens are okay to use?  When would we maybe recommend it?

Jonathan: Sure.  There is really one type of space where a residential screen can be used in a commercial environment, and that's in an office breakout or kitchen where people are just watching television.  If the screen breaks down, it has very low impact to the organisation, and it's cheap to replace.
David: So, there's four categories of commercial LCD screens.  Let's just go through each of these now.  The first one is the Prosumer Range.  Tell us a little bit about Prosumers and when you might use it in a project.
Jonathan: A Prosumer really is a residential screen and the manufacturers built it to such high quality that they've said well, we can actually warrant this in a commercial environment.  so they put the 3-year commercial warranty on the product.  Now, the best place or best applications of those type of screens are simple meeting rooms and collaboration spaces.  The reason?  They're just so cost-effective.
David: Awesome!  Entry level commercial screens is probably the next category.  Now these are a little bit more rugged, a little better build quality, sort of, built for the 16-hour a day, seven days a week use.  When will we use this type of screen?
Jonathan: That's right.  They're much more rugged and robust and as you say, warranted for 16-hour a day 7 days a week.  Now you'd install this screen in a heavily used space, and places where there is a low tolerance for failure.  Places like the boardroom or a heavily used training room.
David: Okay, excellent!  The next level up is, you know, a very high quality commercial LCD screen.  And these are usually built for that very rugged 24/7 environment where reliability is key.  What's an example application where you might use this?
Jonathan: Well, the big application needs for 24/7 is digital signage.  Places like the airport: the arrival or departure screens, menu boards at a retail outlet.
David: And the final category is the video wall category.  So this is kind of unique, isn't it?  Tell us a little bit about what a video wall is?
Jonathan: Well, a video wall really is where you stick a whole hep of LCD screens side by side, and above each other, to make a very large video canvas.  You can effectively create one large image.  The spaces where these are used a lot are command and control centres, in retail environments, and in airports as well.
David: So again, we're looking at the, sort of, very reliable 24/7 type of applications in those examples you just gave.  But one key thing about these screens is their very very thin boarders, isn't it?  So when you do bump these screens up again each other, you know, you almost can't see the borders between the screens.  It's a very pleasing effect, and something you can't get from any other type of screens, can you?
Jonathan: No, that's right and some manufacturers have even got the bezels so small that the overall border between the screens is only 3mm!
