    Im just working out the details and wondered if anyone else has tried anything like this??

    Im considering going with 3 or 4 Optoma 720 1280x800 120Hz short throw projectors in portrait rear projection ($1500 each) on a purpose built curved Plexiglass screen? (2400x1280 Native Nividia/ATI surround or 3200x1280 with 4 projectors using Eyefinity or a hardware based monitor extender from Mviewtech for Nvidia which can also support 120Hz 3d!)

    Thats what Im considering for my next upgrade before Ivybridge-e comes out.

    Combined with an edge blending solution, probably Mviewtech hardware based edge blending compatible with Nvidia 3d (instead of software based so that the desktop can still be used)

    This will create one seamless edge to edge image in a 82" wide x 30" high arc with 4 projectors or 65" wide x 30" high arc with 3 projectors.

    The res given above is quite manageable by todays GPUs in SLI/Crossfire and you cant tell me that something the equivalent size of 3x24" monitors in Landscape isnt wide enough, especially when the screen is 30" high.. Imagine :) hmmmmmmmmmmm

    See calcs below. Still need to work out optimum seating distance and PPI to make sure res is high enough but not too high for the optimum seating position!

    Another different example below with front projection short throw projectors and a different approach to edge blending , though for me 800 vertical res isn't enough (and I think I would prefer the higher vertical res in portrait with this aspect anyway. Going with the rear projection means perfect monitor type quality image with no ambient light problems even if its not in an enclosure. The plexiglass has ambient light absorption properties to give a perfect picture even in well lit rooms or even in daylight!
    Projector throw distance would be right down around minimum .5 of a meter so not very deep either! ;)
    Im still working on the theory and looking for examples and components but I really think the perfect bezel-less solution can be done for under $5K now with these types of parts. Or even much less with cheaper $600 projectors!

    Plexiglas Hi-Def rear projetion screens are lightweight, durable, and offer exceptional performance. The diffusion technology enables the use of short throw and off-axis projection while providing optimal contrast. Hi-Def can also be used outdoors. Largest Sheet size is 81" x 144".

    PS3 120" example of rear projection.

    Anyone got any input, ideas or experience with this sort of thing?

    Fresnel lens ffs. Much cheaper and with added benefits.

    This stuff is cheap and its engineered specifically for rear projection. (it has micro lenses like a fresnel lens BTW)
    They have a studio quality version also designed for indoor use and it's only $175Au per SQ/M.

    no sure if they still sell the ostendo CRVD monitor but it's about the same principal.

    the division lines would annoy me though. maybe have to wait for OLEDs to mature and have a single curved screen

    Thats what the edge blending hardware (or software) is for. It blends the image so its one seamless image. The Ostendo is similar but probably done with 1 or 2 projectors in landscape. Im proposing portrait to get vertical res back! ;)

    Thought you said bezel-less?

    Also, you'll want to calibrate the projectors to make sure the colours are right from projector to projector.

    The reason why portrait imaging usually isn't done with projectors is because the discharge lamps' life is significantly reduced when the lamp is mounted vertically - and typically projectors are designed so that you can tilt the image up and down without violating the horizontal bulb rule, which means portrait projector orientation will almost certainly mean you will have a vertical bulb.

    I have a feeling you'll get better results with less but higher quality projectors than more low quality projectors - but I guess not under three because of the same reason why eyefinity with an even number of screens on each axis doesn't work.

    It is bezel-less... do you see any bezels involved? I know it's projection based, but what im wanting to do is create a reasonably compact large hi-res screen for surround gaming with no LCD bezels.. and this qualifies does it not?

    I have considered the issue of lamp life/heat and keystone issues which is why I want to go with probably LED based 300 to 500Lumens projectors (probably this one the vivitek qumi q2 led projectors only $500ea) which would be mounted at the back in the centre point of each screen position to avoid keystone issues.

    They have been reviewed to have a good image quality beyond what should be possible for a projector in this category! PS. the edge blending software or hardware would fix the offset problems.

    See the black thing around the screen? That'll be a bezel. About 50mm all the way around, by the look of it.

    Not sure I like the overlap idea, to be honest, would like to see it in action, looks like a freaking nightmare to get right. Would be easier to do edge to edge, I would have thought. Lens shift makes that pretty easy...
    Z...

    Edit - Wait... only 65"? WTF? Why? Even 82" - pretty small. Guessing you plan to sit quite close?

    i have one of these projectors. contrast not so great and i think 120hz only works at 720p not 800. not that big a deal.

    looks good in theory but 82" is small for what they can do. my 1 projector is at 136".

    Ummm yeah I guess.. but im comparing conventional LCD multi monitor to what Im planning and I consider it bezel-less because there's no bezels in between each projection. Anyway I wouldnt make the screen with the black boarder like that pic, thats just a front projection example that can be adapted to rear projection with the right kind of screen material... ie the Plexiglas RP.

    I plan on sitting as close as possible without being able to see the pixels, so yes it doesnt need to be 120". I dont want my simulations to be bigger than real life either as its a bit disorienting... It might look cool to go big, but the real immersion is in creating life size images with good peripheral vision which is why im going for curved screen with a slightly higher vertical res that you get in portrait surround! ;)

    Are you forgetting each projector is only going to be doing roughly a 30" high x 25" wide image which is not very much. At the close range I'll be using them they will have plenty of brightness and the rear projection screen enhances the contrast which is already pretty good on the Q2 projectors.

    As mentioned above Im going for something thats akin to a massive curved hires LCD monitor. I dont want it to look anything like front projection which often looks washed out.

    82" wide is a bit small for that effort. i have experience with blending from my projector days many years ago.

    if its lcd i assume you lose your black level. it will be doubly as bright as a minimum. not too bad thes days though.

    im just not seeing your point of doing this? if you had a 140" studio maybe you would benefit, but a widescreen projector would do 90% of what you want?

    how much is the mview? Last blender that was anything decent (in the old days) was a blendzilla at $20K. I am a bit behind the times but as I said, what is the point? blending is for 200" cinemas!

    quadro drivers have multiple projecter edge blending built in, quite a nice little feature
