This was just about a worse possible scenario for projection and obviously outwith the normal range i would be expecting to use the device but it showed me that if the fluorescent lights hadnt been on directly overhead the device is well capable of being used up to about this distance

As to the sound problem some people have commented on previously you have two obvious options to kill the unwanted sound track output by the projector speaker 1 turn on mute on projector and you wont hear it ok if you just want to watch and not listen or 2 the better solution a buy an hdmi audio extractor it definitely can there are two windy feet at the front to allow you to angle the projector they can simply be removed as well as the 2 rubber feet at the back which then exposes holes for a set of screws hope that makes sensethe few drawbacks which arent a huge problemare there is no image size reduction allowing you to fit your image to your screen without having to physically move the projector

There isnt a headphone socket on the projector which was a disappointment but the sound works fine through headphones when ive got the projector plugged into my computer to watch my blurays albeit in 720p

Apart from the resolution problem the other main problem is the amount of light pouring through the ventilation grills and through the bottom of the projector
