Yes I will need to find a proper home for the PJ, centered with the screen.
In your experience, is projector height relative to the screen a critical factor? In other words, is the best image achieved with the projector lens at the centre of the screen?
I could potentially put the projector on a shelf directly over my head (centre of the screen height and width). But if it's not a big issue it would be more convenient to have it higher up (especially for playing Wii!).
So you will be able to correct the pincushion, and you have some CA,
Does position of the prisms relative to the projector, position of the projector relative to the screen, position of the prisms relative to each other, and/or zoom affect CA?
are you happy with the purchase?
At half the price of the next cheapest options I know of, I'm quite pleased with an AR coated optical glass product.
But, if the prisms only cost $8 each from surplus shed (like their other prisms) then the price the group buy paid seems a bit high. Still, I've not no regrets even though my girlfriend doesn't seem so impressed so far
