Hello to all. I got hd-145 lenses on my marquee 8500 and i like that sharpness what those lenses gave. I also have "test bench" macine (marquee 8000 chassis ) with 8" lc tubes and hd-10 lenses, those two projectors are in different locations and i havent done really good side by side comparation between those two. It seems that those hd-10 lenses are not sharp as hd-145.s are ( that was noticed just by lookin phospor grain)
So i´m asking how do you rate lc lenses compaired to ac ones? (sharpness)

Is this near right:

hd8->hd10 ?
hd-144/145->gt-17?
or hd-144/145-> hd-10f?

Or is it so that all lc macines doesent give that good "visible phospor grain" that hd-145 give
My 8500 resolves quite good those one pix off/ one pix on patters @1080p50&60hz ( tested with patters that i-scan hd+ give)

Gonvergense was little off..

Or maybe i just must take that test benc macine to home and start testing

Yes. I used that "good visible grain" method to compair those lenses and how sharp they are, that if P16ln..(lc tubes) tube has smoother surface than 180 dmb tubes, makes that method useles..

I got your point here. Image focus is variable to some extent, otherwise your crispy tube face is always there, like a costant. An irritating one

Ohhh...

I forgot to mention:

P16s (Lc or not), and P19s have smoother surface (I don't have tons of tubes here but I have noticied it clearly on a population of 20 different Mecs, P16, P19 and 180s) which makes your method close to useless. But, this is my experience, a limited one, others may disagree.

Actually i just looked some tubes that i have here.. P16 is smoother than 180xxx are.
