A bit off topics, but i have been using sainsonic 144hz 3D glasses and they work great and are very cheap.
I risked paying almost 4 times more for the benq D3 glasses, ok they are not 4 times better, i would say they are 30% better in total. Brighter, sharper, better face tones, more vibrant colours by about 10~20%. 3D looks that extra touch better with better depth, and 3D layering thanks to the contrast improvement.
Shame on benq for not supplying them with the projector, allowed people to use other brands that let down their product.
