first , let 's set expectation . I do not care if this would replicate a purpose build home theater unit . I buy the optoma because it be small , would sit on a end table beside my couch and have good enough resolution to play game when I point it at my wall . I know it would not display hd , it be less than $ 400 , and it come with a headphone jack so I would not disturb the wife -lrb- too much -rrb- while she be watch tv . I be worry that it would be a little dim , cheaply construct , and difficult to adjust . turn out , it be well constucted , plenty bright -lrb- especially on a\/c power -rrb- , and focus the unit be straightforward . what I do not expect be that it would be bright enough in daylight to watch espn3 through the xbox , play game with no issue , and that it would work with my gorilla camera tripod . when the sun set and the room darken , it work exactly like I hope it would when I buy it . when the sun 's up , I can still use it without issue . if you want a high def experience , buy something else . if you want a hand size projector to play image against a available -lrb- white -rrb- surface in anything but the brightest lighting , this thing work . add a hdmus cable and a Apple HDMI adapter , and you have get a portable projector for Angry bird at 60 '' . who would have think ?
