I have use this item like 3 day and I buy it as a replacement for my old epson and as a complement to my benq ... I have probe it in different condition and I can describe it as follow ... at night light on or off it simply work great in power point presentation and computer general use ... the same for movie ... when connect to the ps3 or my 360 image be not as good as in a lcd tv , but it be possible to play and that be normal if you consider that this projector be 800x600 and it be really cheap ... when connect to my old xbox , my ps2 or the wius it work exactly as a tv , same quality ... anyway I would not recommend this unit to play new video game ... in day light condition it continue work perfectly well ... you can see the image clear even in a image 60 '' wide ... terrific performance for such a cheap projector ... I highly recommend it ... if I compare this projector to my other two one -lrb- a expensive epson and cheap benq -rrb- I only have one thing to say ... why do 'n this acer exist when I buy my first projector ? this one be superior in all term ... Acer x1161p be actually 2700 lumen , not 2500 ... in the economic mode image quality decrease let 's say like 15 % or 20 % in day light condition but it be still ok ... on the other hand , at night you can not hardly see any difference ... if you want to buy a projector take this seriously into consideration ... it be great ... and remember , a replacement lamp be only 128 buck ...
