Here are the only differences I can find from the MyQumi site:
http://www.myqumi.com/specs.php

Contrast ratio:
Q2 = 2,500:1
Q2 Lite = 10,000:1
Isn't 10,000:1 significantly better? Or is this one of those things I won't notice.

File compatibility:
The Q2 Lite does not have a built-in file viewer. For me, the projector will be used for presentations from my laptop and playing movies from my home theater system.

I/O connection ports:
The Q2 does not have a MicroSD port (because it doesn't play files directly). I don't intend to play files from the unit directly.

Standard Accessories:
The Q2 includes a miniHDMI to HDMI cable, miniHDMI to miniHDMI cable, and a carrying pouch. The Q2 Lite does not.

Optional Accessories:
The Q2 Lite does not have the Battery Dock and WiFi USB Dongle options.

The cost difference is about $40 more for the Q2 on Amazon. My main concern is whether the contrast ratio makes that much of a difference. Does 10,000:1 of the Q2 Lite going to have a much better picture than the 2,500:1 of the Q2 (surprisingly, the "lite" model has a better contrast ratio)?

To me, CR makes all the difference. However, most manufacturers specs are pulled out of their rear.

I went with the Q2 Lite. I figured I'd go for the low-cost option with the better (because of CR?) image for business presentations, over the feature differences. I'm hoping that in lighted offices, that the better CR will show the image better.

I called Vivitek about getting a component-to-VGA cable so I can hook this projector up to my home theater system, and they said they don't carry one even though it's mentioned in the user manual. I instead ordered a $5 component-to-VGA cable from Amazon, which sounds like it should work with projectors and HDTVs, but not with computer monitors. It says the VGA port of the device has to support both VGA and component signals, which, it appears, most projectors do.

Yes. VGA is on the same port as the Q2, the "Universal I/O" port. And, yes, the VGA cable is included.



From the specs page:
http://myqumi.com/specs.php

I/O Connection Ports
Q2 Lite
Mini-HDMI, Universal I/O (24-Pin Connector for VGA/Component Input), AV Mini-Jack, Mini-Jack Audio-Out, USB

Standard Accessories
Q2 Lite
Remote Control, 24-pin Universal-In (VGA) Cable, AC Power Adapter, Documentation Kit


Curious, why did you ask? Did you hear somewhere that it doesn't have a VGA port or doesn't include the cable?

Gonna find out. Off-the-shelf, a third-party component-to-VGA cable will not plug into their proprietary Universal I/O port.

But the idea is to go:

component source >>> component-to-VGA cable >>> F/F VGA coupler >>> Qumi VGA-to-Universal I/O cable >>> Universal I/O port on projector


Here's the component-to-VGA cable I ordered:


Qumi VGA-to-Universal I/O cable (included):


VGA F/F coupler to join the 2 cables at the VGA end:


It should work fine if the Qumi projector really does accept YPbPr component signal over VGA through the Universal I/O like the manual says it does.

I got to talk to a technical support on vivitek, he said the lite has 10,000:1 dynamic contrast ratio and the q2 normal has 2,500:1 native CR, he said marketing department made it not clear which is not funny at all to me, I think they made it that way to fool buyers thinking the light is better but in reality, the "normal" having a little high price just make sense more CR than the Q2 lite to make it cheaper.  If it is not too good to be true well we prove it again this time. You all get it right?

To clear doubts- as far as the projection goes, file browser and media player aside, the regular and the lite are the exact same projection unit.
I had the q2, cousin has the lite.
Same exact picture to the smallest detail.

I think they made it that way to fool buyers thinking the light is better but in reality, the "normal" having a little high price just make sense more CR than the Q2 lite to make it cheaper. If it is not too good to be true well we prove it again this time.
