to all the be consider buy this projector !!!! buy it !!! do not worry about the fact it do not have a hdmus input ! buy the converter vga to hdmi -- you can buy the converter for $ 4.87 on ebay.com or $ 7.99 on overstock.com -- this will give you full hd . I use the projector directly on the wall . it have a excellent picture . it beat my 3d benq . all projector over 2000 lumen should be good with light on . the acer with 2700 lumen be fine . if you do not have the converter you be only cheating yourself out of the best performance out of you projector . resolution : native : svga -lrb- 800 x 600 -rrb- no coverter . Maximum : uxga -lrb- 1600 x 1200 -rrb- . Maximum wide : 1080p -lrb- 1920 x 1080 -rrb- with converter . I think I should receive a sponsership for this comment . next be my question . I buy this acer and a LG 3d blu-ray home theater when look to make the movie 3d do I look for glass & a kit compatible with the projector or the blu-ray ? look for answer from anyone else that have a mix-match set that be CURRENTLY get 3d movie to work and not game
