Yahoo let the fun begin. Now if we can get a driver for Nvidia that would be
awesome over HDMI 3D and digitally assigned!!!! Who knows just might happen sooner than later.

Is there a way to use 2 Q5 to make 1080p picture?

not yet, but I am going to make it sooner or later, my girlfriend hates q5 because of the noise it makes. I have planned to buy a 40mm or 50mm case fan, attach a short USB cable to it and plug it in the USB connector in the back of projector. The fan itself would sit right under the projector where is the air intake vent.
I guess the projector is so loud because of the incredibly tiny fans throttling, so I hope adding a bigger one at lower speed might solve the fan noise issue.

If you place two Q5 next each other rotated by 90degrees you can get maximum of 1600x1280 image. Bigger, but It is still not going to be Full HD. But you can input 1080p image to a single Q5, the downscaled Full HD image looks actually much better than native 1280x720.

When Q5 noise in Eco>Q2 noise in normal, were they in slightly different positions. one enclosed and one in open air?
Can you expand on jitters please. What camera?

Noise comparison:

Q5 Eco lowder than Q2 normal immediately;
Position is exactly the same: hanging up side down in open air.

Q5 Normal is twice lowder than Q5 Eco.

There is another annoying issue about noise of Q5. In Eco mode occasionally it increases fan speed as if Normal mode is suddenly on then it reverts after several seconds to previous fan speed. Thus Q5 having better image quality comparing to Q2 is hardly usable for movie watching at home due to loud and variable fan noise.

Re: jitter
It looks the reason for jitters was badly encoded media. I tried playing bluray disk and the image looks smooth and pleasantly nice now.

I will post additional comments on Q5 later in separate message.

I can barely hear the Q5 from 4ft mounted above my head using movie mode!
in full power mode in eco I cannot hear it. You must have one quiet room.

Wounded I'd the USB port could power a raspberry pi, talk about portability.

Finally got my nvidia card to do 1080p and scale on the Q5 without cvt blanking! I used the LG .inf file from
the PA70 thread. For video playback this fantastic. Just when you think it can't get any better someone
provides a better solution. Thanks AVS members and Merry X-mas!!!!!!

So Qumi Q5 owners, how do you feel about the soon to release Qumi Q7 new model? Can you share your thoughts?
post #219 of 231
I saw it at ces today. Non-working case. Talked to staff guy and he said will be 2nd half ship. Price is 8 to 9 hund. He did comment on stupidity of plastic lens as they can't handle the heat. Q7 has glass lens and zoom. Two major advantages over comp.

Yes. I did also notice that, also the rear panel is more organized and no more power bricks, it's a WOW factor imo.smile.gif

I recently got the Qumi Q5 and use it with my custom pc. Im using a Nvidia 660TI and I love my Qumi. I just posted a thread about combining them. I would like to know if by combining 2 projectors do you get a better image and resolution but a 2 in 1 image projection.
post #223 of 231
Here is some tip to improve the image even more:

- download the ECI monitor test patterns:
http://www.eci.org/_media/downloads/monitor/eci_monitortest_pc.zip
- open them full-screen on your projector.
- use your graphics cards output color settings to start the calibration.

Using GPUs output color settings (instead those in projector menu) I managed to improve the image without making Q5 fans throttle.
I use Movie mode in projector which is one of the most silent modes (except for ECO), in graphics card settings for projector image output - adjusted Gamma to 2.0, Contrast to 50 and Brightness to 1 or 2.

Hi Greg, can you link the .ini file or write a short tutorial how you did it?

Hello! I'm new to AVS forum. I'd like to buy QUMI Q5 in near future, but in order to prepare our home for the new projector I hope to know the size of the Power Adapter. I can't find that information on datasheet (L x W x H) so maybe someone of you who already have the projector can measure it. I'd like to know this information because I'm thinking of hiding the Power Adapter inside a hole in the plasterboard from the ceiling. Do you think it gets too hot for that purpose?

Thank you in advance

Can you put a link to the thread.

A glass lens is a major advantage over the competiton in this class of projectors and hopefully no problems with focus.
A zoom lens is definitely a added plus.
Sorry LG Vivitek got my buying dollar close to what I want.
Yes I can make trade offs with price, avalibilility of this projector not having a resoution of 1080P, I can live with 720P.

Qumi 5 + Chromecast + Plex = awesome !

Hi all,

I've had a qumi q5 since sept 12' working flawlessly until earlier today. I use it connected to my laptop via hdmi and also use a ps3 connected with hdmi. Today all of a sudden the white colours being projected appear pink. This totally ruins the viewing.

It's not the cable nor is it the laptop or ps3 because I've checked them all and the de colourisation also appears on the qumi's own menu ie USB setting with nothing else plugged into the Qumi.

I've updated to the latest firmware and also tried as many settings on the qumi as I have access to via hdmi. I've used it in normal power for around 3-4000 hrs.

I've looked at alot of online resources but can't find a solution, any help would be appreciated. Thanks in advance

It's time to make use of the 2 years warranty

My apologies for reviving a several month old thread. Just wanted to point out that Buydig has these for about 280. I bought one without knowing the complexities of DLP link 3D. I assumed (yeah, I know) that getting a 3D DLP Link compatible pair of glasses (specifically approved for Vivitek would be all that I need. It's out for delivery on Sat, but I think I'm not going to be able to use the 3D.

The only sources I have are my phone (Galaxy Note 2 w/MHL HDMI) and laptop HDMI (intel integrated graphics). From what I've seen, the HDMI 1.3 standard isn't really up to snuff.

Does anyone know if there is a way to get my sources to display 3D?
