With the focus adjustment set to fine, I think there is no more than 4-5 clicks difference between the extremes. I have it set to the center of that range, so the difference is really only noticeable when you have a framing pattern on the screen. It's a matter of personal opinion, but especially for 2K projectors, there is something as "too much focus" in my opinion. I rather have the pixels blur a bit into each other than have the pixel grid on full display.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 07-05-2019 01:42 AM                     quote: Marcel Birgelen It's a pretty time consuming process and you need the proper tools to do it right, like at least some good binoculars It is - but not particularly IMO - but aren’t we installers and supposed to carry the right tools? Sound is also time consuming and requires special tools! 🙂  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 07-05-2019 02:30 AM                     "are they even mentioned in the manual" NEC manuals are the worst from all digital projectors I have worked on. Try figuring out how to R&R an NC900 prism from the service manual... there are images from the factory assembly, and the prism is shown on an otherwise bare chassis - obviously one does not need to remove EVERYTHING else to access the prism. You really need to take the NEC service course to learn how to properly take care of them... and the NEC policy of allowing anyone who passed that course to teach it (and then get their students access to the closed service website) is a bit odd. I pity the fool (©1982 Mr. T) who tries to do in depth service on an NC1100L without having taken the service course.  |  IP: Logged Adam Towill Film Handler Posts: 27 From: North Adelaide, South Australia Registered: Jun 2013 posted 07-05-2019 02:33 AM                     Hey guys, Keeping all this in mind. I'm going to look at temporarily moving it on a closed day and see how it performs. Approximate numbers are a throw of 14.3m, currently at 90 degrees to the screen, relocated will be about 85.2 degrees to the screen. Scope ratio is about 5.5m on screen. Realistically, is this something I should touch, or leave to a service agent? Thanks again.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 07-05-2019 05:46 AM                     While the horizontal shift is very limited on the NC900, you should be okay under these conditions. If you're able to do the necessary adjustment in NEC DCC S2, go on. The NC900 has a software limit for shift, depending on lens type. Naturally, don't modify the existing lens files, but copy, and modify the copy, so you can always return to the previous version. - Carsten  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-06-2019 11:31 AM                     My kudos to Mr Pflug! I was told that it didn't adjust by the people at NEC.

The Lens Shift setting almost removed any keystone issues.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-12-2019 09:04 AM                     Nice looking room Cameron!  |  IP: Logged
