Differences on the Philips 3D Active glasses models?

[aleks_wayne]

Hello,
I'm trying to search on google the differences between the different models of the Philips 3D active glasses but there's no info on the net.
I also ask on some stores who sells different models and they really don't know, they just say the difference is on the price...
So some one knows the difference between the pta517 or pta518? Why the different prices?

Have a nice day

Hi,

Could someone answer that Question ? I have already 2 glasses PTA 516, and PTA 507.
I know there is a difference in contrast, and I see the difference : with PTA 507, the colors are more dark..

I'm thinking of buying a third glasses and I don't know which to choose PTA 508, 517 or 518.

I guess PTA 508 has lower contrast as well, but what about PTA 517 & 518. I don't care about confort. I want the best image.

Please someone, answer us !
