Hi again...Im running 1920x1080 res....From my experience with NVG´s wich is about 7 years as a recon scout in the army. I dont remember it to be very grainy, maybe sometimes during rough weather, where not much moon/star light was present. But in good conditons with fresh batteries, they are actually pretty clear. However there was always a feeling that what you looked through was digital/filtered guess this is caused by filters or whatever they are (im not into the tech). :smartass:
Regarding the colour I know there is a difference in colour, some are more green others are more yellow/greenish, maybe this is caused by tiny differences in the plates who filteres the light. I alwaysed liked looking at the more yellowish/brownish green, hence why I want to tweak it a little bit ;)
