I'm currently working on a show using multiple projectors and need to find a way of controling them without using six different laptops.
Does any one know of any software or hardware available that can operate multiple projectors with the same and potentially different images/footage? And is it possible to send one image to two adjacent projectors in such a way so the image appears as one large image?

Hoping someone can help..

Thanks!

This is a question perhaps best posed in the digital PJ or computing forums, however MadMrH might be able to chip in with something useful.

CRT or digital ? Via RS232 ?

Hello kneeya

All things are possible though you have to work through what it is your actually trying to achieve - you cant for instance take a 4:3 or 16:9 Source and Display it across two screens without doing a huge vertical stretch!

What you initially describe sounds like a job for a Videowall processor - you don't 'control' the Projectors you instead have a multiple output box that lives between the Source(s) and the displays and you programme the box to show what you want and when.

The Videowall processor will include frame stores so you can create 'effects' using tiled images, horizontal or vertical stretches, zooms etc.

What is your ideal scenario, is this a permanent or temporary set-up and most important what's the budget????

This isn't going to ba CRT question I'm sure.

Quite a lot of the digital projectors have sufficient zoom and sample to allow them all to be fed the same source.Then just chose a section of one big image.

If its a temporary show then a lot of the big AV hire companies have image splitting equipment as standard.

I use TVONE kit. (about £1500 per channel)

Multi projection with OVERLAP (Blend) zones requires much more control than HARD EDGE to EDGE projction of each image.

Hypotizer STAGE is another. (£6K + but is a showcontrol system as well with graphics etc)

Analogue way Diventix (£15K per 2 video ch)


All of these have individual uses.......

There are many others - I spent 2 years of research into this.........you could do with giving full details of the system , what you send it, what yu want sent out, etc.

Check out my home cinema thread in my signature .

Thats TWIN side by side projection in ONE large image - this style of projection is known as a "Blended" projection.

There is also STACKED which is usually a vertical stack of two or more porjectors that BOTH do the SAME image - This is usually to increase brightness or offer redundancy factor in a live show. side by side stacks as found in some ome cinemas to reduce vertical height required, these are more difficult to setup than a vertical stack.
