after day of totally obsessive research about projector -lrb- 3d , 3d glass , 2d to 3d conversion , full 3d as oppose to `` 3d ready '' and on and on -rrb- , I finally make a somewhat inform decision and order the Optoma gt750e . I have nothing to compare it to , as this be my first projector , but I could not be happier !! my new toy do everything it promise and we have watch several 3d and 2d movie in the comfort of we home - it have even make a 3d fan of my unimpressible husband . the picture be fabulous in a darkened room and good in ambient light . the build in speaker be good enough to enjoy anything you want to watch but HDMI surround sound be better , of course . 3d sound be through the hdmus output so sound be not send to the RCA out or the headphone out when play 3d or convert 2d to 3d . we have use both a Panasonic dmp-bdt210 integrated-wi-fus 3d blu-ray dvd Player and a Sony 3d blu-ray player hook directly to the projector via a hdmus cable . the gt750 recognize the Panasonic immediately but take longer to find the Sony 's input . the picture be great with both player . we have use a king size sheet , a blank wall and now a elite 135 '' screen - the screen give you a fabulous picture but the wall be waaaaay better because you can make the picture so big !! all in all , the gt750 be a delightful toy and I would do it again ! here be what you 'll need if you want to take advantage of the gt750 's 3d capacity -lrb- all be available on Amazon -rrb- - a hdmus 3d capable cable UltraClear HD DLP Link compatible 3d glass - most comfortable for I - work beautifully and best picture overall or optoma bg-zd101 dlp link 3d glass - be a bit heavy but have a great picture - some flash in bright scene or Optoma Technology bg-3drfglass 3d rf rechargeable glass -lrb- radio frequency NOT IR glass -rrb- work with the emitter include with the projector - picture be good and glass be comfortable but the picture be better with dlp glass - you can use all three kind of glass at the same time . also , I find out the hard way , 3d glass can not be find at local retailer . I should have order a extra pair -lrb- or two -rrb- . I also purchase a Panasonic dmp-bdt210 integrated-wi-fus 3d blu-ray dvd Player which play 3d and convert 2d to 3d -lrb- after I follow the advice in the follow quote -rrb- . it also stream Netflix , you Tube and all they friend and you can -lrb- slowly -rrb- search the internet . it be fabulous ! for the Panasonic 2d to 3d conversion fix `` turn on you blu ray player and navigate to setup , next go to player setting , then push tv \/ Device connection . go to 3d setting and go to 3d type , click this and change it to side by side , as this tv support neither full hd -lrb- for 2d-3d conversion -rrb- . once you have change it to side by side , the problem be fix . now insert a non 3d movie and push the 3d button and go to 2d to 3d conversion . you tv will sense 3d content and ask you if you want to switch , you will only have a few seconds to push yes so be ready or it will revert to 2d .
