If the same image measures 1700:1 in one mode, vs 400:1 in another, the drop in contrast will be apparent through the glasses. We aren't talking about stellar contrast ratios to begin with.
These Nvidia vs. DLP-Link arguments are all over the internet. Another AVS member claiming the DLP-Link compromise the image vs the Nvidia setup.http://www.avforums.com/forums/proje...s-picture.html
1) When in DLP link mode, the projector chooses a special picture preset that matches the colour tint of the LCD lenses for DLP link glasses. As a result, it may look wrong with nVidia glasses
2) In DLP link mode, black is no longer black, but a grey/blue. When wearing the glasses it looks more grey again, but it IS compromising contrast ratio significantly as it is shifting the minimum light output in dark areas of the image
3) In DLP link mode, the glasses may become inverted requiring you to go into the projector menu to swap them
4) In DLP link mode, colours look a little more pale so this seems to affect overall image fidelity too
I'll pick up a pair next week to evaluate the differences for myself. Curiosity has gotten the best of me and I want to see the differences (if any) firsthand.
