I've been messing with my Sony HW40ES projector calibration lately trying to maximize the contrast in my room (and try to keep myself from upgrading). I'm using an i1 Display Pro to read using HCFR on a 100" white Silver Ticket screen. The best on/off contrast I can get is around 4000:1, but it's way off in that mode. When I get the greyscale as close as I can get it, I'm getting closer to 2000:1. However, my ANSI is a steady 60:1, no matter my on/off.
I'm a little confused about which one really matters on a projector, but according to this article from Projector Central
, it seems ANSI is the more important of the two. So I'd really like to improve that paltry 60:1, but I'm not sure what exactly to do. If I'm getting the same ANSI regardless of the video mode used, I'd assume it's either the room or the projector panel degrading.
My room is painted dark grey with matte paint, and blacked out completely. So only reflected light from the dark grey walls/ceiling, as well as my brown speakers, is coming back to the screen. I'm not "allowed" (wife) to treat everything in velvet, so paint had to do. When I look at the projector lens, I do see some dust that looks to be trapped between the elements of the lens. I'm sure that's hurting my ANSI, but I don't know if or how I can remove the dust. Is it even worth trying?
I've been considering upgrading to a 4k projector, but don't want to downgrade my picture quality due to my limited budget. I know the lower-end DLP 4k projectors don't have nearly as good an on/off as the Sony, but what about ANSI? That seems to be an elusive measurement to find, despite Projector Central claiming it's the more important of the two. Thanks for any help, suggestions, and recommendations.
