Personally I would go with the Nvidia glasses, but I believe any generic DLP shutterglasses will work so you can save some money (like these: http://www.i-glassesstore.com/dlp3d-wireless-2set.html
). I don't know for sure if the X102 will work or not although they should. Nvidia has a good driver but the iz3d driver is also pretty good. Some games look better with one or the other but overall they are comparable. Yes, some DLP sets have issues with overscan, this is a hardware problem so it will be across the board whichever driver you use. If you want to do PS3/BluRay 3D then don't get the Nvidia glasses. Nvidia is PC only. The generic glasses should work with anything, though.
