I thought the same thing about the wear, until I discovered this below
the blue and red tubes show the phosphur grain a the very top edge of the screen(screen is 35" in height and the top 2 inches or so shows the grain as plain as day, as good as the green or maybe even better) I cannot for the life of me get it to focus up properly on the middle of the screen, I have played with my tilt and V flapping adjustment for hours on end with blistered fingers from my screw driver
my rasters are perfectly centered up and down, left and right
I encountered a problem like this before, using maximum raster and the HD-144 special lenses on my Barco 808, grain would never come in like it should in my setup, I went back to the HD-8's and there was my grain, I wish I had a hd-18 lens laying around so I could test, but before with the hd-144 problem no tubes would come in, my green right now is showing mighty fine grain
I swear this is due to my throw distance, I am 18% clsoer that what the manual gives, most folks say that 5% closer is pushing it for a NEC, I have tried to track down a throw distance calculator for the HD-134m's but to no help I can't
I also could be fighting my 2.35:1 screen
Thanks Cliff, I think the horz lines are actually starting to get worse, the blue tube is very very bad right now :(
PLEASE post pics so that I can see this, and as well post some screenshots of the final image. I'm serious about this and have asked for it several times now for a reason. I know we are all busy big dog but spending a few minutes taking some good shots will make all the difference in the world.
DO NOT PPHHUUCCKK AROUND WITH THE H POT!!!! Put it back to where it was!
I had a situation with this PJ where in I was messing around with existing memories and was unable to maximize the raster via amplitude because of the existing setup. When I erased everything, all of the sudden I had one hell of a lot more adjustment on amplitude as a result.
I had no problem filling the raster with where the PJ was in the first place. You really should avoid messing with the PJ in that manner if possible.
With these type of lenses and ESPECIALLY with using the type of raster/lense combo like you are, you should have NO problem acheiving excellent focus.
Are you using my memories for your work? If so, your next step is to reset the projector and start from scratch.
Make sure that you DELETE ALL setup memories on the pj before you reset it. I can walk you through this if yoiu like before I leave for WV tomorrow.
At this point, I'm damn tempted to just drive down.........
I couldn't imagine that you could not be getting the results that I did but at the same time, if your trying to get 720P from a screen ratio like what you have, this could be the cause as well.
Ken really needs to pay you a visit......
