Hi there, folks


After seeing many PJs here and there, trying to grasp differences that probably only existed in my imagination, I was confronted with an (economic) offer that I could simply not refuse and bought myself a Yamaha DPX-1000


The PJ is quite good. The croma aberration is impossible to discern on normal viewing conditions and the image processing circuity does wonders even with less than average soruces (i.e., a $200 DVD player). The blistering speed of DLPs also struck me, as well as the overall quality of the optics and general build of the apparatus. Color is also very good, very neutral, even with factory settings.


Rainbows are there and you don't need to make an effort to see them, but I already counted on that. But the - motion - posterization is terrible. It realy ruins the whole thing.


I was wondering if there is anyone out there who has the same PJ or the same problem (posterization) with an HD2 machine and has found ways of minimising it. There is a thread on posterisation out there but it already quite old...


Cheers

Ok, so last night I installed a new OS in my HTPC with a custom resolution of [email protected] via DVI. The PJ resolved a 1:1 pattern flawlessly, but best of all, much of the posterization was gone... I could not believe my eyes!


I don't know whether I should attribute this to the absence of D/A A/D conversions, to the scaling performed by the computer or to the fact that I was viewing a 25fps source (I live in a PAL country) at 60hz. My greatest fear is that the improvement is caused by the 60hz refresh rate, as it has the effect of breaking down the smoothness in DVD playback (the effect is something akin to NTSC 3:2 telecine conversion, but with an origin of 25fps instead of 24fps). And it is precisely in those smooth camera pans that posterization shows up! I wonder if the improvements in posterisation will stay once that I configure my HTPC for [email protected] I recall some other member stating that he could see much more posterization with PAL DVDs than with NTSC material.
