Question 1

The is suppose to be a 3D projector. Does that mean it's automatically one or is that a special setting? In other words, can I use it like a normal projector? Thanks for any and all help.

Accepted Answer

There are 3 settings you may have to do for 3d...

turn 3d on/off
type of 3d input (default is auto)
and then an invert setting ( sort of like a sync).

Just be sure to turn 3D off when you go to another source...like TV

Just noticed this is going for 599.  Don't hesitate...buy it.

Question 2

Can this be mounted on the ceiling?

Accepted Answer

Yes, ceiling mount on this unit works just fine, the image can be flipped on the projector so there is no need to do something special with the device you are connecting to it. There are pre-tapped screw holes on the bottom that will work with a universal mount. Download the manual from the manufacturer for those screw sizes if the mount you choose doesn't include all screws.

Question 3

Can this be ceiling mounted?

Accepted Answer

Yes, I mounted this projector to the ceiling using the kit that was provided with the projector at purchase.  The hardware provided was terrible and some of it would not work for my installation, and the necessary thread type was basically unavailable when I went to the box stores to find it.  We ultimately found something that was fairly close, and forced it to work.  It is steady and works fine.

Question 4

Can I use it for Power Point presentations in a classroom?

Accepted Answer

I would say yes.  I originally bought for business presentations but use it for watching movies at home.  The screen is very bright and easy to hookup to a laptop.  Should work well.

Question 5

How does it compare to an Optoma HD180? The Optoma died on me after 2.5 years (video card problem probably due to overheating) and wanted another projector with a little upgrade in video quality. Would this be a good buy? I'm willing to spend $850 at most...

Accepted Answer

I have only used the Acer, but it had amazing video quality, great color and detail on a 116" diagonal screen. It did have 2 negative points for me.
 Rainbow effect, which I finally noticed was happening whenever I blinked while watching high contrast scenes
Fan noise when not in Eco mode was considerable, and still audible even in Eco mode

Question 6

Is this able to be mounted upside down?

Accepted Answer

Yes, or backward mounted, there's a 1/4 20 hole on the bottom and 3 3mm holes

Question 7

Do I need to connect to a computer?

Accepted Answer

No. you don't have to unless you want something to see from your computer. you can DVD - blue ray player, dish receiver or anythig that can play video.

Question 8

Need to know throw distance... Screen is 92 inches diag... Projector mount is14 feet away...

Will this projector work?

Accepted Answer

According to the calculator I found, it's outside of the optimal range for this device.

14 feet will get you a 130" diagonal screen.  At most, you'd want to mount this projector 10' away for that screen size.

There are plenty of image adjustments this thing can make though, and with most nvidia- or AMD-based video cards, you can do further adjustments with the video drivers.  (Assuming you're hooking this up to a computer.  Game consoles and Blu-Ray players may not have the same luck.)

Question 9

What is the contract ratio?

Accepted Answer

Contrast ratio is the ratio of the light reflected from an all white image and an all black image. So a projector with a 1500:1 contrast ratio means that the white image is 1500 times brighter than the black image. The higher the contrast ratio, the more detail you can see on the projected image. Contrast is what makes it possible for us to see the subtle shades of colors. So good contrast is all about seeing the details.  Light sources are the "enemy" of contrast, and that is why movie theatres are dark.  This projector uses DLP technology, which is what they use in the movie theatres, and it greatly outperforms LCD or LED (at least for my purposes).  The 3,000 lumens is the key I think.

It is 10,000 :  1 on this particular model.

Type in Acer H6510BD datasheet in your browser's search window, and it will take you to the full data sheet.
This is an incredible projector, especially given the price.  Love mine.

Question 10

What is the maximum throw of this product? I'm looking to use it outside in my backyard. Need a distance that is a little further back...15-20ft

Accepted Answer

This projector actually works pretty well with distance. I have use it outside and although I cannot give you an exact distance I would say about I used it at about 15-17ft. One downside is you will most likely need to turn up the brightness and not have eco mode on so that will shorten your lamp life but it will work great at a far distance. It has two adjustments that will help you adjust the screen size and focus by hand.

PS. I currently have it in a room about 10 ft back from the wall in eco mode in a dark lit room and it hits about 72inch. but the size is put down quite a bit to fit the wall. it goes well over 90" at full size from this distance.
