I'm struggling to understand why one DLP tv with the HD2+ chip would apparently perform so much better than another. I mean at the end of the day we have a lamp, the HD2+ chip, the colour wheel and the screen, surely pretty much all of those are common to all the HD2+ DLP TVs? What is it that makes one perform so much worse e.g. with the Sagem HD-D45 the contouring and breaking up of the picture on pans, what's the cause? I'm sure this problem or something very similar also affected the Optoma H77 projector and just thought it was a DLP thing to be honest. Cheers, Andy.
