I shop several store and heavily on-line before I purchase this projection unit . I want a projector for outdoors on my covered deck . the problem be could I find one that be go to be bright enough for a outdoor application where a lot of late afternoon sun would be . I must say I have be impress with this unit . yes there be time where the picture become a little wash out but overall it have be great . the biggest problem be when direct light be reflect onto the screen -- then it become wash out . during the most daylight time the picture be clear and bright . at night or in lower light the picture be excellent . when first use this I have a standard definition source and be use RCA cable to carry signal to the projector . when I move to a hd satellite box and a 25-foot HDMI cable -lrb-  cmple Ultra High speed HDMI Cable , 25 foot  the sound from the box itself be very limited . the volume do not raise very high and the quality be rather flat . I hook up a sound bar -lrb-  ilive itp100b two Channel Bar Speaker System with docking and recharge Station for iPhone and iPod -lrb- Black -rrb-  I be project about 25 foot away from the screen and have size the image -lrb- use a zoom setting -rrb- to about a 74-inch screen . I be project onto a piece of white tile board that I purchase at a home store . the quality , detail , color , and clarity be very impressive .
