Projector vs Video Wall

[otto...@gmail.com]

Our church projector is in need of replacement and we were about ready to pull the trigger on an Epson EB-PU1008B 8500 Lumen projector to replace our 6000 Lumen Panasonic. 

A friend is steering me toward a video wall setup or large (98") TV. It would gain us brightness and clarity. We currently are projecting to an 8' x 6' screen and don't have a lot of space to go 10' wide. 

I've been looking at doing a 2 x 2 video array using 55" monitors. A system like LG has a 3.5mm black line between screens. Other systems that cost more can be narrower.

What has your experience been with a video wall vs a projector? Does the black line between screens have to be considered when putting PowerPoint slides together or is it narrow enough that your eyes ignore it? Are these screens non reflective or will that be an issue?

Have you installed a video wall that can be folded against the wall or winched (tilted flat) when not in use. Our screen is about 9 feet from the front of the sanctuary. See attached photo.

We recently replaced our projector with an newer projector instead of going to screens on the wall for the following reasons:

1. New projector was a huge upgrade in brightness and sharpness of resolution so everything is much clearer and easier to see.

2. We have conduit going to our projector location, switching to screens would have involved running new wired connections

to the wall where we would have put the screens, which would have been a big increase in cost.

We didn't want to trust our projection system to wireless connections.

3. We did not consider a video wall as a replacement for the large projector screen that we have so I can't speak to

how those gaps of the bezels of the TV's would impact the powerpoint. I believe that would not work well

because we display a lot of text on our slides, and I don't know how a video wall handles large amounts of text

displayed on a screen. I have mostly seen video walls used with more graphics with less text or larger text that

is still readable across a thin bezel.

4. Our contractor also brought up the other con of using TV's versus a projector screen combo. You will always have large 

black boxes on the walls. When we aren't using our screen for a worship service like during funerals, I roll the screen up

(ours has a motor to roll and unroll the screen from its case) and then there isn't this huge screen just hanging on the

sanctuary wall that isn't being used.

5. We have a significant amount of sunlight that comes into our sanctuary during morning worship, we actually have shades

over one side of our clear story because the morning sun can wash out even our new projector. We were unsure if multiple

TV's would be big enough and bright enough to actually give us a better picture than we get with our very large screen currently.

6. Our contractor has installed lots of projector/screen combos and TV solutions as well, so they would have been

comfortable with either direction, but after considering all of the pros and cons, a new Epson laser projector gave us incredible

clarity and brightness over our projector from 2010, and kept the aesthetics of our sanctuary the same.

Including details here for those that may be interested in video walls.

Mount Calvary had a projected system for 14 years and the projectors finally failed and needed to be replaced.  We also have a sanctuary that has windows on both the north and west side which provides an abundance of light which makes it sometime challenging to project from the back of church to the screens that are in the front.

We then looked to the possibility of video screens.  There were many concerns that the picture may be grainy or may show the delineations between the modules of the screen.   I can tell you that those that doubted the solution were pleasantly surprised when we finalized our installation and used them in worship for the first time.   They are bright and can be used in a dark sanctuary or on days when there is bright sun as well.   We use the screens weekly for worship and school chapel as well as movie nights and bible studies that have videos.

It has been a blessing to our congregation.
