Shouldn't these charts also factor in the throw distances between min-max (or are these just all assumed at mid point)?
In my case I run at -7 and about a 17' throw from a 110" diag screen which represents about 30% short of max (tried to find a good trade off between lumens and max on/off). How would I adjust the throw distance to these numbers to get an accurate read between the X55 and X75 in an attempt to justify the added contrast (of the x75), over cost? What I'm trying to discern assuming my throw distance doesn't skew Geof's numbers is... would a difference of 14.5K (at -7), be a real world noticable difference to justify the premium over the X55?
Also FWIW - I bought a couple x104 glasses and compared to both the original & new JVC glasses and I can find no
discernible differences whatsoever (for my screen of course). What I found most interesting is by tweaking the glasses using the Xpand software and turning down white to -3 as what was posted earlier by Jason on his shootout thread, I think I do perceive less
dark ghosting. I have more to test but at about $65-75 for these glasses they seem to be an excellent value (and much more comfortable for glasses wearers too!). Edited by krichter1 - 11/25/12 at 2:16pm
