This is a combination of my posts so far to try and keep blending posts together as suggested by MC Maniac (who did not offend me ).
I will edit this post as things change, I will only "bump" this thread for major changes but will edit as small changes happen. PLEASE voice any opinions.
28/6/05 - added SEOS response, added contrast modulation pj thread link.
.....and so it begins.....
Blending options software, firmware & external equipment I have looked into
Nvidia Quadro FX cards, others did not get good results from these cards. I have written to Nvidia but no response.
Watchout - PC based software - approx cost £4,500 for the software and you need 3 pc's! (too expensive)
Analogue WAY - £16,750 - WAY too expensive - hardware based
Panaram - hardware based - £25,000
Matrox PJ range of cards - offer 3 & 4 head display with OVERLAY only. $2000 or $3000 - PCI card based - NOT ON GENERAL SALE but current models
DScalar - currently being looked at
Baro SEMU - currently being looked at
Barco polaris - software for use with projection within domes etc
SEOS - their answer to my question of do you do anything that would help us?
"Unfortunately, SEOS specialises in complete display system solutions for the flight simulation market and Virtual Reality centres - we don't offer systems compatible with your requirements as these can be purchased at lower cost "off-the-shelf".
Items I have so far
Nvidia Quadro FX4000 card - I know loads think this is a poor starting point BUT the 4000 is the top AGP card with the latest drivers - Installed
I currently have 2 Barco 801s - one data, one half turned into graphics - Both will be graphics when new boards arrive which are also on route (some arrived 7/6/05). The graphics has scheimpflug adjustment, higher resolution.
I am lucky enough to have 2 soft edge & contrast modulated boards for an 801s Arrived
7/6/05. They take the place of input 3 board so I must change back to RGBHV inputs.
I have 3 convergance on green boards (These wont fit the 801s ) - but I intend to end up with a pair of 1208/9 if this actually works - Arrived
I have the base of a RG801 (non s) this has a convergance on green tray which might work.Anyone got the modified convergance on green boards for a 801s? or Soft edge contrast modulated for later projectors
, cash waiting.If anyone in the UK has a 801s D or G kicking about I could do with it any condition even non working, with toasted tubes
cash waiting - currently one of mine is in my cinema room, the other is ready for this setup - I dont want to loose the use of my cinema while I play with these toys......As I think this will take me many weeks to progress.
I will try and post pics as this moves forward
My reasons for trying this are as follows
Use of more vertical tube size so higher resolution and brightness- My Main Reason (see below*)
Slight increase in brightness PJ nearer screen - not a main reason
Better convergance stability PJ nearer screen - not a main reason
* I have a fixed 16:9 screen, widescreen from one PJ uses 75% of vertical tube height - hence the masks you see on loads of tubes
As I calculate 2 PJ with a 25% overlay should use 98.4375% of the vertical tube height - and greatly increase the resolution to a total picture of 2100x1600 and give a 25% increase in brightness per projector, which will mean a % increase in brightness overall not sure how that bit works !
I know there are people out there who dont think this will use any more tube area - I could be wrong - but to date no one has convinced me of that. The combined tube area becomes almost (within 2% inc. overlay) a native 16:9
Boy I is gonna feel silly if I got that wrong
Maybe I will fail
but along the way I will have tried something new, had a bit of fun, and will accept the "told you so's" of course if I succeed "A large shout of were not worthy"
will be heard from the non believers.
Currently the odds are 5% in the blenders favour and 95% against
Others please send me a PM and I will add your info here, so far this is info I found within other posts

Pj's with contrast modulation as standard
My own notes in case anyone wants to follow my progress
Nvidia Quadro FX4000 - Installed in my HTPC running v6.x.x.x drivers, latest is 7.x.x.x . Unable to update drivers without the loss of the Nvidia control system. (3 attempts) Will build a new driver disk and start again. Also picture quality seems to have a more "grainy" apprearance. Colours are however much more vibrant but brightness is lower. possible driver conflict issues so will start with a fresh drive. loss of output from card at times - this may well be motherboard related as I have had this in the past with my ATi board.
Noticed that the Nvidia site has the download for drivers and user manual the wrong way round! Also first line of the .pdf file for work station user guide spells station wrong "Staion"
. So my faith in Nvidia is weak. They have also removed their on line shop for ONE MONTH while they update it!
(seller of this card on ebay gradogrado NOT TRUSTED - bought as new obviously second hand, rude and abusive on phone)
