Man no HDCP is kind of a letdown frown.gif
post #2012 of 2165
Why do you say that? I routinely display HiDef by HDMI from a Humax HD-FOX T2 - this requires HDCP.
post #2013 of 2165
well does it work? from my understanding if you have no HDCP support you don't get a picture? I don't want to have it always tethered to my PC.

?

Of course it works. That's what I said. I don't know where you got the idea it doesn't work. Have you tried it? If not, why haven't you tried it?

I must of looked at your response wrong, and I don't have this projector yet I'm looking to get a idea if I want it or not. I'm curious to see how it holds up.

Last night I successfully achieved 3D on my QUMI 2 for the first time since buying it a year ago. Though I have not tried any 3D BD players on it yet, I had success hooking up my FUJI W3 3D camera through a VP3D1 adapter to the QUMI. On the Fuji W3 I chose 3D HDMI option, and on the QUMI the 3D option became available when I selected a 3D pic (MPO file) on the W3. Then I was able to select the DLP-Link option in the QUMI 3D menu. So then I opened and took out my active 3D glasses for the first time and voila! Even my wife was impressed and she is super picky about 3D glasses. The room was dimly lit and screen size in the neighborhood of 6 ft. Now if only I could convert some 3D movies to MPO format and play them back on the Fuji W3 I'd be set.... smile.gif

How did the 3D look? I was wondering if it would be too dim to be useable.
post #2018 of 2165
It did seem dimmer that than the 2D image would be, but I think I will enjoy watching a full length 3D movie. I hope to try Avatar this weekend so I'll post a follow up. I can take a pic of the screen which will not be an aligned pic but will ive an idea of the brightness. I can even post a 3D pic I think using my Fuji W3. The QUMI was being projected in a dimly lit room on a low ratio (maybe 1:1) screen which is about all I could come up with in a home-made screen in Brazil. The projector is about 7 feet from the screen and brightness for 2D movies is just fine. The 3D itself was great, or as good as my camera plus photographic skills allow. Seeing the pics on-screen I realize how important it is to tweak the images before projection now - alignment and cropping mostly. BTW, I got the glasses I got off Amazon, 3DTV Corp. - $60 for two pair.

Good luck trying to photograph a time-division multiplex 3D display with a 3D camera!
post #2020 of 2165
wink.gif Haha - Thanks. The request was about brightness reduction so I just took a pic showing the same frozen frame on the projection screen with the glasses and without. I'll post the pic. There are probably be other factors, but having the same frame and and camera settings, the image should answer the question.

I followed the steps posited by Sherazta on page 65 of this thread using my brother-in-law's PS3, but in Portuguese (we live in Brazil) I was having a hard time with the menu. So I finally switched to English on the PS3 and got 3D on my QUMI2 via a VP3D1 converter($200 on Amamazon).

I grabbed a 3D BD of Avatar, knowing my wife would love to see it again, and the first 3D movie experience on my QUMI2 was - unreadable subtitles and garbled 3D video. I checked that I did have DLP_Link selected in the 3D menu on the QUMI. I thought my 3D glasses must have a problem. Actually I think it has to do with synch. Anyway after a few minutes of weird 3D and unreadable Portuguese subtitles I thought the left/right views look reversed. So I rotated the glasses 180 degrees and Bingo! Now, we did have them on the correct way to begin with so don't go there. But I can suspect there is a setting somewhere I haven't checked yet that will allow me to to reverse the left/right views. Anyway my wife liked the fit of the glasses better upside down.

Once the glasses were readjusted, the 3D was excellent, the subtitles strangely appearing somewhere in between the foreground and background much of the time. The white floating seeds seemed at time to appear between us and the screen. I was most impressed by the scene in the river after the main character jumped off a cliff into a water fall. Excellent 3D.

As one would expect the brightness with the glasses on was quite reduced. (pic below). I have read in this thread it may be 75% as bright. That's a lot for a' movie like Avatar that has many, many scenes in a forest, at night or otherwise not bright scenes. But my wife said she thought the 3D from the QUMI was much better than what we saw at the 3D dolby digital theatre in town. So that means it will do for now. Besides I only have one other 3D BD, Prometheus, and a lot of it is dark scenarios too. But next trip to the USA I'll be looking to pick up a brighter projector.

Can't wait for a copy of the hobbit or other 3D movies I haven't see yet - Hugo, Shrek 3, etc.

Cheers -

The glasses present alternate frames to alternate eyes, so already the transmission is down to 50% just by the multiplexing. Then you have the on-state opacity of the LCD in the glasses to contend with, so if the transmission is 75% you only get 37.5% brightness at best. This can be compensated for by making the picture smaller, but that rather defeats the objective.

Had my son and daughter-in-law over during the weekend to watch the Brazil x England soccer game. Afterwards I guessed correctly that he wanted to see some 3D since he hadn't been over since I set up the Qumi + PS3. Both he and his wife were amazed watching Avatar, as my wife too had been. They all agreed the image was better than in a local 3D cinema, sound too according to my son. And my sound set up is not really balanced well. So the local 3D cinema must be poorly set up - big possibility. My son complained about how dim THE HOBBIT was at the local 3D cinema, and the whole experience very disappointing. I saw it in an IMAX 3D in the States and was very impressed with the 3D and image quality. So when my son rents or buys THE HOBBIT 3D BD to watch on the Qumi + PS3, it will be interesting to compare notes. All I need now is two more pair of 3D glasses...

How big a screen do you have?
It all really depends on the movie. The first part of Thor in 3D is practically unwatchable in 3D on my 96" screen. Very dark, but the 2D version, even in theaters was very dark also.
post #2025 of 2165
My projection size is close to 72". I have no measuring device and cannot buy one since I am somewhat incapacitated temporarily due to recent shoulder surgery. I am using a larger screen that was built to accommodate an older 2000 lumen projector whose bulb had blown for a second time. It was great when it worked, but neither it nor a couple of backup units could survive 2 voltage surges within a year's time. At 72" the Qumi 2 is bright enough in a dimly lit room. For Avatar, I find it dark but watchable. The PS3 has been returned to my brother-in-law who just bought a 52" TV so I will not be watching anymore 3D till I buy a PS3 myself ($500 here in Brazil) or a decent 3D BD player. I am considering a Samsung E5500.

Hi all,

Never felt the need of joining the forum because my doubts about products were easily answered just doing a search in such a great forum. However, I couldn't find any answer to this, so I would really appreciate it if any of you could help me here:
I am planning to buy a Qumi q2 lite and would like to transmit the audio using a bluetooth transmitter so I can pair the audio out of the Qumi with my bluetooth speakers (trying to get rid of cables). However all the bluetooth transmitters I found must be powered using usb. So I was wondering if the usb in the Qumi q2 could power a transmitter. If any of you has the Qumi and could try to connect a cellphone or any other device that charges through usb to the Qumi usb port to see whether it charges or not, I would really appreciate it.

Thanks a lot in advance
post #2027 of 2165
Your wish... yes it does.
post #2028 of 2165
Thanks a lot for your answer. Which Qumi do you have? I am planning to buy the Q2 lite and just hoping the usb port provides power since according the specifications is for "service only". The usb port of the regular Q2 and Q5 can read files on a usb stick but not the usb on the Q2 lite, so not sure the Q2 lite can provide power. Cheers.
post #2029 of 2165
Sorry, I wasn't aware of the "lite" and presumed you meant Q2 rather than Q5. What's the difference? I never use the USB port anyway.

post #2030 of 2165
Just want to add that the USB port on the QUMI 2b, I think "b" stands for "white" ,has no audio out utility... I like the idea of using blue tooth speakers though! exactly how do you plan to set it up?
post #2031 of 2165
Actually bought a good tape measure and discovered that my projection screen size is only 60". The physical screen will take a larger projection but with the ambient light we like to have I'd rather get a different projector with more lumens rather than moving the QUMI to the wall behind the sofa and having the image more washed out. The QUMI is a great small projector and my wife is very happy with it, but for me, the brighter and bigger the better - especially for3D.
post #2032 of 2165
You definitely need to control the ambient lighting with the Qumi, particularly with the longer throws, but I find it good enough in dark or near dark conditions. 3D is another issue though. A problem I have at the moment is that it needs to be too near the screen for a particular application I have in mind, and I can find no convenient way of increasing the effective focal length of the lens.

Re the Bluetooth idea, presumably the audio will come from the 3.5mm jack, and the USB will only be used to power the Bluetooth transmitter. I am concerned that the system delays will cause the sound to be out of sync with the picture (not a problem for audio-only applications). An alternative would be the iTrip type of FM audio repeaters - they are analogue, and therefore have minimal delays.
post #2033 of 2165
Yes, exactly, that's my plan, the transmitter will be connected to the audio-out port via 3.5mm jack and the USB will be used to power the transmitter. I thought about the delay but I think it's worth to give it a try since some reviewers of these transmitters say there is not delay with tv image and the projector will be pretty close to the speakers. A fm transmitter is not an option for me because my speakers don't have radio.
Anyone with the lite can confirm the usb port is able to power a device?

Thanks to all!
post #2034 of 2165
From comments about the Qumi 2 Lite on Amazons website, it looks like it will not power external devices. The USB port is for input from laptops and tablets.
post #2035 of 2165
Thanks for your post, but I read all the comments in Amazon and bhphoto and couldn't find anything that suggests that. The usb port is for service only but that doesn't mean it can power a device. Moreover, according to the instructions manual it's usb type A, so it should be able to provide power... Cheers

If you already have them I think a trial (with a TV or whatever) would put any concerns to rest (or cause you to reassess your plans).
post #2037 of 2165
I already ordered the transmitter but it will take a while to get here. As soon as I receive it I will try it and post the results here, in case anyone is interested. Cheers
post #2038 of 2165
By the way, just did a quick trial watching al jazeera in my iphone and streaming the audio to my speakers via bluetooth and there was no delay at all, so I hope the transmittter works the same way.
post #2039 of 2165
Good news.
post #2040 of 2165
I quote - "The lite does not have an SD slot and will not play from USB. In effect, the normal version seems to have an in built player and file finder, whereas the lite requires a device or computer that has the player already as an input to project."

First page on Amazon.com listing the Vivitek Qumi 2 - Lite B

Cheers
