I would think with a curved screen and warping software you could achieve the desired results with only 2 or 3 projectors.
I think again, not certain that for 5 you need Eyefinity for that and a supporting card. Only a few cards support 5 or even 6 outputs at once. Not all 7970 for example do. This also brings an issue as some of those displays I believe must use DP connections, if not then adapters. Yes their are other ways to achieve such with other hardware or software but not an out of box solution for HDMI or projectors.
Really it seems that projectors are not being manufactured to properly accommodate this issue. If so we would have certified Display Port models available.
Regards screens and I know this is something Mike and some others have spent along time with. Just some of my own thoughts so please correct me or give your own opinions.
For me 16:9 is too shallow really, maybe more so a problem for flight sims. Triple 16:9 is too wide to an extent going beyond our real FOV.
I have been told by a local pilot for British Airways that regards simulators a large curved screen is fantastic with a large open world with far reaching area and draw distance. So perfect for a flight simulator and being up in the sky. His opinion for such on a cockpit would be visually more limited simply because a typical racing game the draw distance or the open world of the track is much more confined. Also in a race car your not needing to look up/down into the virtual world anywhere as much compared to a flight sim.
Remco has shown with altering a games FOV and a screen up close perhaps to get around the shallowness of 16:9 he can achieve a superb realism in scale. I know you guys, Mayaman and Mike have done several screen layouts and perhaps achieved similar.
Personally for me I think I will go for that kind of realism in scale but using the width of 16:9 to wrap right around for the side doors. So keep the screens up close like Remco has but with triples? See how many of the triple monitor guys do this idea to get 180 degrees viewing yet try to maximise being in the car not having full triple screens in FOV at all times. It no doubt also helps increase the size of their screens.
The problem is you cannot get say a 25-50" tall screen (for realistic cockpit depending on viewing distance) unless the projectors are far back. You then like he had was shadows or projection onto yourself. With a model like the W1070 this is super easy to achieve either from rear projection or ceiling mounted units at a short range. DLP short throw 1080p may be the best route to go and it supporting 1600x1200 could be an option as Mike you seem to of went back to 4:3. Anyways I am hopeful...
No doubt more similar models will be appearing this year, if only they were certified and had DP or support with triple HDMI.
By all means feedback or opinions are welcomed.
Have any of you tried this?
