Compact and light weight , this be aim squarely at the travel business person who need to make presentation while travel , but it be also a handy general purpose projector , if you can accept a few limitation in exchange for the low price . pro : very compact , low price , excellent image quality , good color , good build quality , easy to use , good remote con : no hdmus input , remote not backlit the high lumen mean this projector be very bright and can be use in a room with a fair amount of ambient light . a step up from the 800x600 210 model , the 310 's 1024x768 resolution and 4:3 aspect ratio be fine for present and for dvd 's , gaming , and many video format . it be equivalent to 720p hd -- higher resolution than standard dvd video -lrb- 640x480 -rrb- and fine for streaming video , divx , home video , photo , and similar use . it be very well suit for laptop video game with a mid-level graphic card as well . you get Epson build quality and reliability , long bulb life , good out of the box color , instant on\/off , usb instant play -lrb- for photo , presentation , and pc display , but not suitable for video -rrb- , and VGA -lrb- good for pc Video and general display purpose -rrb- . you get vertical -lrb- but not horizontal , that be reserve for the more expensive 315 model -rrb- lens shift and lot of tweaking option -lrb- most of which you will not need -rrb- . this unit be very quick and easy to set-up and use , and quick to shutdown and pack up as well . I use the VGA input to connect my laptop to the projector , everything work fine and be quick and easy to setup . projector detect the video signal and the auto config work as expect . I project a 84 '' -lrb- diagonal -rrb- image use ECO mode -lrb- lower power\/brightness , less noise , longer lamp life -rrb- and leave the auto iris on -lrb- better black -rrb- . I do not need to make any adjustment to color , everything look good to I . the image quality be excellent for the price . for business purpose , it be very good . for home media , it be acceptable and , at this price , very decent . the black be not `` inky , '' but the image be bright and colorful . also a good choice for gaming via the VGA connection . there be no hdmus at this price , not a issue for business use , but it mean you 'll have to use component output to the VGA input connector via a special cable -lrb- not include -rrb- for best quality dvd\/movie video . no usb cable be include , either , which be a bit lame in my opinion , but , hey , look at the price ! verdict : the basic idea here be to deliver a good quality , budget projector that feature Epson 's key image and build quality , and basic feature , at the lowest cost possible , I believe Epson have hit the target and that these projector will be quite popular . I have raise my initial 4 star rating to 5 star base on my test and performance vs. cost -lrb- i.e. bang for the buck -rrb- . a excellent business projector and a handy all-around projector when use with a laptop or desktop pc via the VGA connector . --------------------- Update 2011-12-01 : photo and Art image look very good to excellent . there be plenty of detail , very bright , fairly sharp , wonderful color fidelity , and overall great image quality . I also do some limited testing to see how this unit would work with streaming video for casual movie watch -lrb- e.g. netflix , Amazon Instant video , etc. -rrb- . image quality be very acceptable . Blacks be decent , thing that be black , look black . this be no match for a good home theater unit , no inky black and `` pop '' here , but a very decent and eminently watchable image . would be great for sport , I be guess . I watch some Netflix film and they look very good , dvd quality plus\/minus depend on source . the Amazon video I watch -lrb- Firefly non-hd -rrb- be a bit lower in quality , but still acceptable . some native video -lrb- i.e. play from laptop hard drive -rrb- look great , near or better than dvd quality , YouTube video be pixellate due to they low resolution , but the higher rez look ok . -lrb- on a 84 '' image , you be go to notice block and pixellation w\/youtube and other lower quality source , so keep that in mind . -rrb- I use blutooth speaker or headphone for audio - do not bother with the projector audio . all in all , it be fun and I be very pleased with the result . I think many would be perfectly happy with this projector for casual movie\/video use -lrb- just do not compare it to a moderate to high-end HT unit -rrb- . the wonderful hbe -lrb- human brain effect -rrb- take over after awhile and you do not really notice any image quality issue . perfectly enjoyable and very inexpensive by comparison . also very easy to set-up and put-away . I project the image on my light beige wall and even that look pretty good . the auto iris do click a bit occasionally -lrb- as with most other unit -rrb- , but you can turn it off if this bother you . it improve the black a little bit , noticeable , but not a dramatic change . if you do not get too hang up on the lower resolution -lrb- vs. the newer 1080p unit -rrb- , moderate screen door effect -lrb- never bother I at all -rrb- , you 'll have a lot of fun . and , at current price , this be hard to beat in term of fun\/dollars spend .
