Projector that displays on two walls?

[TMBS]

Hi

 

I've had an odd request from our Drama teacher. He wants a projector that will display on two walls, his room is used for teaching and assemblies. I've never heard of one but didn't know if anyone else had?

 

He wants it to be able to display on one wall for assemblies and then when he's teaching to display on another.

 

Thanks[MENTION][/MENTION]

Do you mean like two projectors showing the same thing at once on two walls? Or one projector that can be used on two walls (at separate times?)

 

The first one would surely just be a VGA (insert other) splitter.

 

The second, being a rotatable mount (assuming throw distances work with your projector).

 

The other option is two different projectors (We had a room that was dividable into 4 areas with partition walls, so each classroom had their own projector, then a big one for when it was a 4-room room)

Hi Steve

 

Ideally one projector. I don't think a rotatable mount would work as they're really high ceilings. I've suggested two projectors and/or an interactive screen but he didn't want those...

 

Thanks

They're not exactly the cheapest option, but there are plates that have electric rotation, with pre-set settings.

 

So you could program in "Assembly" and "Class" settings etc (Think of like car seats that have programs).

 

But really it sounds like you need to ask him exactly the purpose of this As if it doesn't want two projectors etc, the question would be why and what does he want, as will he be happy changing rotation etc himself if not?

 

Big TV on wheels?!?

I think this is the way forward

 

 

The electronic mount might work but depends on how long the pole can be...

One with a VCR underneath in a locked metal box? :-)

A 'two-image throw' solution my last place of work was going to use in a new computer room as I was leaving was:

 

1. Interactive display/board (RICOH or similar)
   
2. Ceiling mounted projector projecting second image to second wall

2 projectors will give the best solution, and probably be cheapest. Maybe 2 different brands so the 1 remote doesn't switch the wrong projector on? Or some manufacturers allow you "key" the projectors so 1 remote can do both, but you have to select which channel you want to use.

Looks about £3k worth of projector! It would make a Casio projector seem cheap.

A large mirror, or one on a selfie stick?

 

Two large displays I think is your only option here, but gets expensive if you want touch as well.

I've seen classrooms with 2 projectors and they just duplicate.

We have a couple of wheeled screen stands - something capable of holding a 75" display and with motorised height adjustment is (I think) about £800. A 75" non-touch display (i.e. a TV screen) is also about £800, just for rough pricing. You get a 4k display for that with much better brightness and contrast than your average projected display, and installation / setup is fairly minimal, you just need a couple of pairs of hand to help get the screen bolted to the stand.

A wheeled display could be the better option, but thought would need to be given to cable management and display size ratios. Also (as usual) please look at the commercial display screens rather than consumer products. Although you can buy a consumer grade 75" screen for around £800 it won't be covered by any warranty when the manufacturers discover it was installed in a school. Commercial equipment is designed to show static content (Powerpoints rather than television) and will be covered by any warranty claims. A quick search shows 75" commercial screens start around £1500 ex VAT, and dhicks is right about the motorised trolley around £800 ex VAT.

Good point - the wheeled stands we have have enough room inside the structure to hold a 4-way power strip, with a 5-metre cable for plugging in, you just need to make sure there's a wall socket at each point you might want to plug the display in. We haven't had any problems (so far...) with our home-style LG displays, a couple of which have been in use for 2 years now. A nice feature of commercial displays, though, is an OPS slot for mounting a suitable PC, which makes for a nice all-in-one setup (turn the screen on and the PC turns on too) and saves confusion in a classroom setting with having to remember a separate PC is switched on. Saying that, we actually have one of the LG displays powering a Raspberry Pi from its built-in USB sockets, so the whole thing starts up when the power to the display comes on.
