Tips:Church Led Video Wall Instead Of a Projector

  LED video walls are quite popular display products, you may be see it for outdoor sports stadiums,big churches etc.

  A question is if you consider a video wall instead of a projector for worship,here are a few parameters led video wall vs projector.

  Projector Brightness

  This one is a little more subjective, but we're finding that if a church wants to talk about a projector in the 12-14K lumen range or higher, we should probably start talking about a led video wall. Now, I should make it clear that a led video wall is not going to be the same initial cost as a 14K lumen projector. It's going to cost more up front. However, when we do the math, often the delta is low enough that it makes sense to go with a led video wall.

  Video walls for churches don't need lamp changes, they can be mounted to the wall or flown and don't require a clear path from viewing screen to projector. The overall service life of a led church signs is likely to be longer, and they generally require less maintenance. At the end of the day the wall may still be more money, but the extra value it brings is often worth it. Not every time, but sometimes.

  Ambient Light Levels

  a few years ago, I've worked with churches that are not the modern "black box" style of sanctuary. One had a giant 300 sq. ft. stained glass window right next to their screen. And yeah, it faced south. My first thought was led video wall for them for two reasons. First, it would have the punch that no projector ever would making it possible to actually overcome all that ambient lighting. Second, and maybe more importantly for me, the blacks would actually be black. You see, a screen will only ever be as dark as the white screen ever gets. When there is that much ambient light in the room, it's never going to be darker than light grey.

  That destroys contrast which makes the already not bright enough projector seem even more washed out. By contrast, the background of a led video wall—the space between the pixels—is black. And when the LED is off, it's black. I don't care what the contrast ratio spec says about a projector, it only matters if the room is very dark. In a full light situation, the screen looses.

  Screen Location

  Some churches want to use a big backdrop stage led screen. Projectors can be problematic because if people get too close to the screen, they'll cast shadows unless you do rear projection. But rear projection requires a big backstage area. If you want to do a wide screen, you'll need to blend the projectors, and that can be tricky and may need adjusting from time to time. And the screen will still be competing with stage light.

  When we switched from a 16K projector to a led video wall at Coast Hills, the biggest thing we all noticed was that the stage lights had no effect on the video image. Whereas before we had to be really careful where we pointed the lights, how much haze we used and even where we hung fixtures, the video wall had enough power to punch through all of it. And the blacks stayed black no matter what.

  Like I said, there are no hard and fast rules. Yet. Video wall technology is advancing at breakneck speed and almost every year we're seeing an increase in pixel density, and a decrease in weight and cost. Brightness isn't changing much; they're already bright enough. But we're also seeing refresh rates go up, and processing quality improve all the time.

  All of that to say, if you're thinking about replacing or upgrading some projectors, especially larger ones, it's worth looking into led video walls. They don't make sense in every case, but when they do, they're a big win.
