Native Resolution is WVGA(854×480)  It will accept resolutions up to 720p (1280×720) and WXGA – 1280×800

2) Largest image you can project and how far do you have to be to achieve it?

Technically you can project a 10 foot diagonal image (that’s big), unless you want fairly dim image in a dark room. In a well controlled room though a 4, 5 or 6 foot image is very practical and offer a reasonably bright picture.

3) Standard battery life?

Approximately 1 hour.  Light weight 3rd party external battery packs can improve on that.

Yes, has a massive 2 Gig of memory, no wonder it can do all it can, with documents, videos and more.

Uses LED light and lasts an estimated 20,000 hours. 

6) What is the native aspect ratio and does it support other aspect ratios?

16:9 but does support 4:3 aspect ratios. 

7) What’s the story on where to place the projector?

As an example, if you want a 60″ diagonal image, the front of the projector will be about 50 inches away, a 1.2:1 throw ratio

8) Does it have a remote control?

Yes, it comes with a full featured remote control. 

9) Does it have a full featured control panel on the projector?

10) What type of warranty does it have?

1 Year limited parts and labor. 90 days on the battery. 

11) Does it have a focus adjustment?

Yes. However does not have a zoom adjustment. Must be physically moved to produce a smaller or larger image.  The focus is rather sensitive.

12) What inputs/ouputs does the projector have?

One input for video signal that accepts a VGA cable, a RCA cable and a micro-USB input too. Also accepts HDMI through a mini HDMI port.

The highest resolution it will accept is 1280×800 through the VGA adapter. HD video sources are accepted via the mini HDMI port and will accept a 1080i signal, per Optoma, but I did not have luck with 1080i the one time I tried it before settling on 720p from my PS3.

17) What cables does the projector come with, and WHAT might I need?

The projector comes with one VGA cable to connect your laptop and one RCA cable wiR audioth L/. For S-video you will need an optional cable.

Dark environments with little ambient light for best viewing. A much better projector for sharing what you want, with a few people not a large room full of them.
