Hi yokoyoko !

Finally, I built my triple screen stand : http://www.gamoover.net/Forums/index.php?topic=27617.msg447586#msg447586
1725

and I bought a third motor ... to ADD the traction loss :-)) thanks

Bonjour Mat,

your monitor stand looks really good. Will the monitors move with the traction loss or will they be static?

If you need further infos for building the tl please feel free to ask!

thanks,
it was tricky because the arms were not designed for been horizontal ... so I had to cope with this pb and add an adjustment bolt
1742
but ... I can test several configuration as drawn before !!! for 20€
yesss

But, no, they won't be moving : too shaggy !

Thks, I'll try to make some drawing to get advices from you about the building !

Some changes to my rig:

Short throw video projector instead of triple screen. For now I am very pleased but some tweaks and improvements will be needed for sure.

Some impressions you can see here in the video. Detail views of the setup in the end of the video:

Waouh! I really like it, well done Yokoyoko!
:-D
It is more immersive, I bet!

Could you share the price/link?
And approximative dimensions of vid's support?

Thanks
Mat

Hi Yokoyoko,

Very impressive !!The screen just front of the wheel , very good idea.You cut the screen , your hands are in the same position as in the game.Really nice setup with a big accuracy to setup all the stuff.

Could you give some more informations:
Which game ? I recognize the nordschleife but not the game.
Projector informations

;)

Hi guys,

thx for the comments!

It is more immersive, I bet!

Yes, it is really cool :D I always wanted to try this since I saw the videos of remco hitman (who was the first I know who realised his rig with such a video projector setup).
Before using the projector I used 3x120hz 27inch screens from iiyama (these: http://www.amazon.de/Iiyama-G2773HS-GB1-widescreen-TFT-Monitor-Reaktionszeit/dp/B007W6X7NM/ref=sr_1_1?ie=UTF8&qid=1385909171&sr=8-1&keywords=iiyama+g2773hs. This was pretty cool too. But with 3xFull HD resolution my Nvidia GTX680 4GB graphic card was really at it's limit in games like P.Cars. or Assetto Corsa (with nearly everything maxed out). rFactor or Iracing isn't really a problem for a modern graphic card, even at triple screens.

As you said - I think too that this projector setup is really immersive :!: Ofcourse there are not only advantages to triple screens. I think on this topic everyone has decide on it's own (like always ;) ). For example for online racing it would be nice to see the right mirror - but with my current setup it is not possible with a correct field of view. The correct field of view is so impresive important!!! I would never change this even 1° from the calculated one :!:

For rfactor (horizontal fov) in my example:
-screen height: 82cm
-distance eyes to screen center: 55cm

82cm/2=41cm ---> 41cm/55cm=0,74545 ---> invers tanges of 0,74545=36,7 ---> 36,7 x 2= ~73° FOV

For games like Assetto Corsa or P.Cars. you will have to use vertical fov... it is the same routine just with the width of the screen. 145cm in my case.

Some other tweaks for a more immersive setup:
- go to your rfactor *.plr file and set (under graphic options) Cockpit Vibration Mult1, Cockpit Vibration Freq1, Cockpit Vibration Mult2, Cockpit Vibration Freq2 to zero.
- in the *.plr set max framerate to -120 or -180 or -240 - try what looks the smoothes - with my 120hz projector I use -240 but you will have to prove that your graphic card can deliver these 240 fps all the time
- In game settings I maxed out everything (graphic setting wise)
- in Nvidea inspector I use alot of Anisotrope filtering - as my distance to the screen is realy near
- EDIT: create an own resoltion in Nvidia Inspector (downsampling) - I use atm 2560x1440 @ 120hz

And approximative dimensions of vid's support?

Sorry I don't understand this question - can you ask with other words please?

Which game ? I recognize the nordschleife but not the game.
Projector informations


Hi Vicpopo - as tombo said - it is rFactor (oldie but goldie) :lol:
The mod is the PCC 2007 from GSFM with the 997 GT3 Cup. You will find it here: http://www.team-gsmf.org/page/index.php
The track is the Nürburgring version of COM8. http://www.rfactorcentral.com/detail.cfm?ID=Nordschleife
I set in the car settings the ffb multiplikator to 1.8 with my T500RS wheel. Ffb effects to "low" and 100% strength in game settings.

The projector is a Optoma GT760 short throw projector. http://www.amazon.de/s/?ie=UTF8&keywords=optoma+gt760&tag=googhydr08-21&index=aps&hvadid=22510936106&hvpos=1t1&hvexid=&hvnetw=g&hvrand=1511214041557180599&hvpone=&hvptwo=&hvqmt=e&hvdev=c&ref=pd_sl_8lztenm6zn_e
I really would had haved the Benq W1080ST (with 1080p nativ instead of 720p as the Optoma) BUT the "throw" of this would have been to long. I mounted the projector in the end of my rig where the traction loss slides from left to right. This is the only way - as I wanted to move the projector with the rig while the car in game looses traction. The screen moves to with the rig. Depending on this I only have very limited space between the projector and the screen :( - the Optoma is now 74cm away from the screen. The Benq would need for the same size of screen a distance of about 120cm! This was not possible for the room where the rig is "housed" in.

You can see this projection is not ultra expensive - indeed it costs half the money that my 120hz triple screen setup had cost. The projector can run 120hz too - what I strongly recommend!

The screen is done in the same way as I did my hometheatre screen some years ago. It is 3mm MDF (wood) which is coated with "black widow" screen paint. ---> REALLY BRILLIANT STUFF http://en.wikipedia.org/wiki/Black_Widow_%28paint_mix%29 - beats every commercial mid to high end screen easily :!: Costs for the screen around 40€

a big accuracy to setup all the stuff
ohh yes - it is a real pain.

Things to do:
- make the projector mounting more stable
- adjust everything that the shadows of the steering wheel will disappear
- move the screen some cm more downwards
- black border around the screen
- paint the back of the screen or mask it with carbon film

Best regards

:shock: sorry, my question should have been : what is the height of your projector mounting?
and you gave the distance of 74cm ;-)
