I'm about to buy an Infocus X1 DLP projector, and have a couple of questions. I have demo'ed a SP4800 but cannot get a demo of an X1, I understand the firmware and default settings are different between the two. I was very impressed by the image of the 4800, I am assuming I can get the same results with the X1. Is there any reason to spend 33% more on the 4800? Has anyone used this unit with a denon DVD-2200 prog scan player? If so which gives the better image 480p into the VGA port or 480i into the svideo port using the faroujda video processor? Is there much difference between the two? I have heard rumours that the X1 will be losing the faroujda chipset in the near future, has it happened yet and if so how can I identify whether the model I am getting has the faroujda or not (I am talking about markings on the box or something similar - I can't demo the X1). Can anyone recommend a screen that works well with this unit, something about 90 inch diagonal. Is it worth doing A DIY screen or are the results better with a bought one? Thanks in advance. Harry.
