What do you think? Is better this projector LCD or a LED 1000 lumens projector(Such as Dell M900HD)?

I am not familiar with the other projector but have been very happy using the Epson for powerpoint presentation. Easy to use and very sharp quality.

One suggestion for Sangean if they're listening ... I have the PR-D5 ... you should have an option to keep the display lit continuously if the user wants it. (Like the 909x, which I also own).

This is one of the brightest projectors available. My screen is 110" and could be much larger with excellent brightness, even with 3D, the ultimate brightness killer. Projector is 16' from screen, with room to move it forward or backward (see on-line manual for size vs. distance.)

Well depending on ebay you really want it for would make the choice. I own this lg pa77u and love it. Not 1080p bit close enough and super bright and led so last forever. Lg does make an upgraded model starts with an 85 or something it does full 1080p but no 3d and it's double the price. Lg led orojectors are super compact Erich is really nice but the way technology is going all tvs and projectors are gonna be the 4k soon so if you have the funds I'd find a led 4k projector but if not and on a budget the lg pa77u is the answer. Is awesome just read the reviews. On this particular item they don't lie. Hope that helps Well depending on ebay you really want it for would make the choice. I own this lg pa77u and love it.

Hi there, sorry late response. This projector is very good, for presentations as well. However it's not strong enough to work with daylight, just closing curtains is not enough, it has to be really dark. In the evenings it works perfectly, even with lights on!!! I mainly use it to watch movies in the evenings, perfect! Especially the big screen, love it!

I believe with the 3500 lumens you could push a 50' screen and it would still look sharp. I do a 40' screen with a 2000 lumens projector and it looks great, but it has to be dark. I am not an expert, but I have been doing outside movies for the neighborhood for over 10 years for fun.

I have the 100" airbright 3d it works decent I have a great viewing angle. Every time someone comes over to watch the game or movies they all love it. I do have some sort of image imperfection on the screen. Its only noticable on a white screen projected. I did send back one screen because of it and it was the same type of imperfection on the new screen. The problem is you won't see it until the screen is fully put together. I said forget it the second time around it was not that major to have to restrech another screen..overall I would give this screen a 7.5 out of 10. Its the best you will find for the money.

It all depends of how much dark you can get your classroom and how big your screen would be So, you can buy it and adjust the size of your screen accordingly to the brightness in room Some hints: First -This is one of the brightest led projectors yet (even LG PF85U with 1000 lumens is somehow not so more strong, because image seem those they boost with a wite lamp to get more lumens, like acer k530) Second: Led lamps do not get weak over the time like regular ones do, and the light is somehow much less yellow tinted, so one 700 lumens led projector, can be compared with a much brighter regular lamp projector, like a old 2000 lumens lamp one Third: If you want a brighter and much more powerfull projector, that lasts more than 20.000 hrs, specially to use in classrooms, go to the casio signature models, with 2500 to 3000 lumens (white light also). Those casios have not so great color balance, costs like U$ 830 to U$1000, but are the perfect choice for educational issues, and are really realy strong (there is a youtube presentation were a guy uses it's internal laser source to cut appart some plastic garbage, to show how strong is its light source - of course, when iside the projector, its laser is safe and does not hurt anyone - but dont stay staring directly to the light at short distances, as you wouldnt do also on a 3000 lumens lamp projector...)

Your blacks are only as good as the lack of ambient light in the room, and that holds true for any projector regardless of whether it's 60 lumens or 6000 lumens. The 3M is really a $200 projector, the Roku stick makes up the other $100. If you draw the shades during your office presentation and hit a normal projection screen then this little projector does a respectable job. If you're in a normally lit room and not hitting the screen with any direct light you can hit your screen with 40 or 50" image that's also quite respectable. If you're in a darkened room then it looks quite good even out to 6 feet. It runs equally bright on battery power or when it's plugged in and there is a power saver mode that reduced the brightness by about 25% to increase battery life. The batteries will easily take you through a 1.5 to 2 hour presentation in full on mode and probably 3 or 4 hours in power saver mode. There is also a function that turns just the bulb off and on instantly so you don't have to go through a boot up sequence (especially handy if you use the Roku stick) I have used for 5 different presentations myself, and my little 3M projector is currently in China being used for several presentations to show high quality stock footage. I also use it when I travel so I can watch Amazon or Netflix or Hulu Plus in my hotel room on a 5 or 6 foot projection Obviously a white wall is best but it's not too shabby on an off white wall if the room is dark. Bottom line, it's a nice little projector, very portable, very high quality product and nice image quality at 720p. Based on my personal experience with this projector I would recommend it for home entertainment and for smaller office presentations.

quick one that comes to mind is if you have a dark room, plasma should be better. But i personally like LED, aside from being a new technology, on a side by side comparison, the picture looks a lot awesome in LED than in plasma...

It does better than comparable lumen models I have owned. The lighting location matters, I.e. if you turn on a lamp on the opposite wall you'll see very little change... but if you turn the overhead lights on near the screen it is considerably washed out. With my mini blinds closed in the middle of the day the picture is still very good. Short throw does matter I believe. Not sure if I'm saying this correctly but I believe the closer the source the less effect light pollution has on it. If your looking for a projector to use with over head halogen lighting you'll need a significantly higher lumen version. It does better than comparable lumen models I have owned.

Check the service tag on Dell's site and it should give you a list of hardware, or open the half of the laptop that contains the screen and look at the back of it. Regardless of whether its CCFL or LED, just go with LED and get the right video cable for the motherboard. Going with LED will cost you about 1/3 the price. CCFL is not mass produced anymore.

It depends on your preference. You can definitely watch it in a lighted room, but, as with all projectors, the colors will look richer in a darkened room.

This isn't an LED Light Source machine.... it is Single 0.65" DC3 DMD DLP Technology by Texas Instruments system. I just bought this unit as it is 1080p vs my Optoma HD66 which was 720p. You would have to watch a lot of TV 2 put 6000 hrs on one of these. I plan on replacing mine around 4000 hrs. if I ever needed to. I would recommend this to all my friends, it is a great projector for the money.

Actually online aficionado......The new Samsung LED's are WORSE. It is mentioned in cnets reviews and some have left comments here on amazon. One guy mentioned how he can see streaks running through his new LED tv in a dark room. So yeah... LCD's only look good when the lights are on.My friend has a panasonic plasma that he games on a lot. NO BURN IT. There is temporary image retention but that goes away fast.

I don't really do photographic work. It is far superior to the old TN screen it replaced. Without putting an IPS display next to it I couldn't make a decent comparison. Now that Dell is running sales on their 24" 4K IPS display I'd take a closer look at that. If you do get this 28" display keep fluorescent lights away from it. Fluorescent flicker plus 30Hz refresh = ugh.

I don't know the gain, but I can tell you that for the price, it's a good screen. I'm using a 1600 lumen projector throwing 18 ft and the picture is clean and clear.
