order this projector after read good review here and elsewhere . initially I be quite impressed by the image quality , very decent 720p image that match my expectaion . however , about 9 month into use , the projector start develop bad pixel . I make the obviouse mistake of not return it on the spot for a in-warranty repair . initially just a few ... but the situation deteriorate over time . I be now about 18 month from first use and the device be unusable ; there be over 100 bad pixel -lrb- mostly white -rrb- plus a `` bad '' black line run across at about 2\/3 the screen . obviously there be something significantly wrong with the reliability of the dlp device use in this design ... I have contact customer support ... look forward to they reply . Update May-31-12 : have return the unit to Optoma for repair - they gracefully accept this as a `` in warranty repair '' even though technically out of the guarantee 12-month period . good expereince ... make I comfortable of purchase optoma product in the future .
