I buy a pc last year with the nVidia 3d system , it come with a Samsung monitor and it look fantastic . I instantly think `` i need a bigger screen '' so I go to nVidia 's page to view compatible display . the Optoma hd66 be and still be list as be compatible an support . so I buy one ... well guess what ? it be neither compatible or currently support . if you search the nvidium page you will find that if you hd66 be build before August of 2010 -lrb- that be right , August of 2010 ! -rrb- it will not work . I then call Optoma tech support and be tell by the phone tech that in order for it to work , it have to be send back to the factory for modification and that I would be responsible for the shipping ... I tell the guy that that be outrageous and I would simply return it and get something that actually do work as advertise . in case you wonder , I purchase the Acer h5360 . . I should have purchase it the first time around , not only do the 3d work flawlessly , it have way more feature than the hd66 like `` auto keystone , auto orientation , color wall compensation '' to name a few . if you look for a 3d projector that really deliver , you can wait two month till the actually compatible hd66 's hit the street -lrb- and hope they work -rrb- or you can get the Acer h5360 . of course deal with Amazon be the only way to go , the return of the hd66 be simple and I be enjoy real 3d in my living room on the Acer .
