small projector with 4 point keystone and edge blending

( Boy I is gonna feel silly if I got that wrong )

The combined tube area becomes almost (within 2% inc.

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. * 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 tubesĪs 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 ! Slight increase in brightness PJ nearer screen - not a main reasonīetter convergance stability PJ nearer screen - not a main reason My reasons for trying this are as followsUse of more vertical tube size so higher resolution and brightness- My Main Reason (see below*) $2000 or $3000 - PCI card based - NOT ON GENERAL SALE but current modelsīaro SEMU - I have 2 boards not sure if SEMU or SEMU lite - can only tell when in projector will update as I find outīarco polaris - software for use with projection within domes etc Matrox PJ range of cards - offer 3 & 4 head display with OVERLAY only. Panaram - hardware based - £25,000 - Hardware based Watchout - PC based software - approx cost £4,500 for the software and you need 3 pc's Nvidia Quadro FX cards, others did not get good results from these cards BUT they were using the FX1000, I have on test the FX4000 AGP card, support for edge blending on the FX1000 has been dropped by Nvidia, the FX4000 is still supported. and so it begins.Blending options software, firmware & external equipment I have looked into
