Had a change to spend a couple of hours with a pre-production HS50 yesterday afternoon. He was connected to a sony dvp 999es palyer with components playing PAL progressive. The screen was a high contrast (short of grey) PROJECTA (similar to the da lites here in Europe).
I had some time also to play with the menu which is different from my vpl-vw12ht one.
The screen door is totaly absent. From a viewing distance of 4 meters and having a 110 inch diagonal screen the image was so smooth a film like that it remind me the one of an Infocus 7205 that one friend of mine has.
Colors were perfect (mind that my 12ht is calibrated to D65 with SMART III and has a CC30R filter), and the pj was extremely silent (at low lamp mode).
Now to the contrast issue, it is by no means 6000:1, BUT it is superrior to anything i have seen in sub 6000 eur. category including DLPs.
Gray scale is smooth and accurate, and the blacks are at a matterhorn dlp level. Iris was at auto (combining nice light output and good blacks) but i thought is was a bit slow (but not distructing at all) when reacting to from the brightest image to the dimest (although i need more time to spend with the pj be sure about this).
Build quality is no near my 12ht but it makes sense according to the price.
Well, will i buy him??
Yes, because for these amounr of money it the best pq i have seen and it can be better if calibrated properly (the options available are more than enough, i.e. Real color processing, Black level - high,low, Iris settings, color temps etc).
Well, thats for now. I can answer any question (if i know the answer of course) but bear in mind the time difference (i leave in south Europe).
