Only had about an hour to play with this little device. I placed it between a Lumagen Radiance and a Lumis HOST. No sync issues noted, except once I lost sync while flipping the effect on and off.
It definitely adds a level of clarity to my already sharp DLP picture. I ended up mostly watching with POP at 70%. That may end up being too high after I have more time to evaluate, but it looked pretty good to me. I suspect I will eventually end up somewhere between 50 and 70%.
Overall, I will give it a thumbs up. Definitely a keeper. Will give it a go in 3D on my Optoma tonight.
