Hi All,
Today I have received a call from one of my client which is actually an architect company. Please take a look at his requirement :

--> : They will take 3 HD pics from 3 different cameras and pic would be covering 180 degrees area for eg they will take a panoramic image from left to right and they will process this image and will give me one single image .Obviously this final output image would be too wide to fit on single display. So now they wants it to show to their customer via projector and they already have circular projector room setup in their office.

So my point is should I look for one HD projector that could process such a high definition wide image or should I use 3 different projectors using ATI eyefinity technology?

AMD Eyefinity Technology

Please help me guys.
 
Maybe because they do not want the bezels of the displays to interfere in the image.

Eyefinity is the way to go @havoknation, a HD7870 2GB should do the trick in my opinion for redundancy you can also look at a slightly more powerful HD7950 2GB.

GPU is not an issue, i could even plug 7970HD but I am wondering about which Projector and how many of it to render such a wide image at 1:1

Talk to the client about the image size and placement of projector's.

In our college I handled a 720p projector and the lens itself was ~4 inches across, so in your case if you use a single projector it needs to be a big and good one OR 3 smaller but equally bright projector's synced up with Eyefinity. That is something that no one can help you with, you will have to do it yourself.

Sure will ask to my client about image resolution and further details

but @ALPHA17, one more doubt rises, say if i attach 3 * 1920_1080p projectors in eyefinity then will my final output resolution be 5760(1920+1920+19200) * 1080 ?

Don't think there's a single projector that does this. Even if there is, it'll be prohibitively expensive. I'd say get 3 projectors and configure them side by side. Sounds like the most logical solution. Make sure that the projectors have keystone correction as you'd definitely need to do that in this case.
 
I haven't used the Eyefinity tech. before nor have I seen one in person so I can't comment much about that.

If projectors are going to be expensive, why not use a bunch of LCDs instead? 3~4 LCDs wall mounted driven by HDMI over the Eyefinity tech. should be fine IMO. The bezels might be a hindrance here but when viewed from a distance, it may not be that obvious. There are LED displays available in the market with very thin bezels so do consider this option as well. Besides, the IQ, black levels, and the contrast from the LCDs would be miles ahead of a projector's display (a projector cannot project black light and thus relies on the darkness of the screen here) for devices of the same budget. Aesthetically, I'd say the LCDs would look much better than the projectors and will require the least time, money and efforts to get everything done.

With projectors, you will have to invest in a good projection screen (pull-down types) or if this is going to be a permanent setup, you will need to do all the necessary framework. And then you will have to do the ceiling mounts, conceal all the cables and run it all the way to the PC, invest in lengthy cables and so forth. So keep all those in mind.

Yes that should be the final resolution. Essentially, the pixels along horizontal res. add up.

Could you please comment on keystone correction a bit more?
@Gannu
Thanks for the above post. I will talk to my client for LED/LCD option.
