Good Evening All,We are in the final stages of buying our equipment for our church plant, and due to the facility we have opted to go with 2 50'' TVs. The room is 40x40 with 120 chairs. A few questionsAre 50'' TVs big enough? We are thinking of doing 2, one on each side of the stage.Which TVs are durable, and are rugged enough to withstand packing\unpacking every week and moving around in a trailer?Any other thoughts on TVs?Thanks,Bryce SwansonInnovate Church

Typical rule of thumb is to measure the distance between the screen and the furthest viewer, and then divide by 6. That number should be roughly the image height of your screen. (Or sometimes use /8 for larger content, for /4 for more detailed content), and keep no one should be "off-axis" off the screen by more than 45 degrees to either side (the letter "O" starts to look like "I" once you are too far off-axis)
Image viewing, especially for text, is greatly a function of the image height. A typical 16:9 format 50" flat panel display provides an image just over 2' high, which is probably good for viewing from a maximum of 12' to 20' depending on the content. So I'll echo Jordan's comments that while a 50" display may sound like it would be big, it is likely much too small for that space. What I tell people to do is go to an electronics store and stand the distance from the screens that your furthest viewer would be from your screen and think about what you plan to display on your screens. You might be surprised how small those images look at that distance. Well, I'd say stick with professional models from manufacturers like LG, NEC and Samsung. Avoid consumer models whose warranties exclude any commercial or professional use, And get some good quality flight cases and some good quality, heavy duty stands, both of which are probably going to represent a substantial cost on their own. And if their use is critical then you might want to purchase three or four displays so that you have a backup or two.What are the sources for the images and how do you plan to get them to two displays? How high do the displays need to be in order to be viewed by everyone and how tall of a stand does that require?
I am generally a buy the best and keep it a long time kind of guy, but not when it comes to displays. I think the best way to resolve the tension between cost and "we should upgrade" is to buy consumer displays and resell them every year, or two at the most. Displays have been getting bigger, better and cheaper at a fierce rate, so one or two sizes below the largest model will generally be an area of the price sheet that has already been heavily discounted. We have had excellent luck with Sharp products all around our campus over the last 10 years, but of course we aren't roading them. I suspect we are about three years away from, better than current HD, 12'-15' displays at commodity prices. Projector based setups will become a thing of the past soon there after.
Bryce,I set a room with two 80" widescreen LED TVs to replace the screen/projector package in a room of similar size to what you described…and I felt that they should have been larger.See picture. I'm about 5' 7" tall, by the way, so my arm-span is about that same distance.
I had a Client that thought this way until they had spent more in a year on consumer devices that had failed and were not warrantied in the application than if they had simply purchased commercial units to start with and eventually they replaced everything with commercial units. But what was a critical factor in that application, and may be in many others, was the impact of a failure.One aspect of that is the potential effect of any failure or problem on the intended purpose or use of the displays. Is any failure or possible loss of use of a more critical nature? Another factor can be how any replacement will be funded and if that funding will be readily available. In some cases it may be easier or more practical to get greater initial funding than it is to get ongoing funding for repairs and replacement.
We are talking about a display in a church not an anesthesia machine. I realize long warranties give a system integrator or contractor the easy out when there is a problem but warranty length has nothing to do with quality or reliability. A Kia is not less likely to fail or last longer than a Honda just because it has a longer warranty.
