VIVITEK QUMI LED 1280x800 - Page 60

post #1771 of 2165
has anyone gotten the ps3 to do 3d without an adaptor like 3dxl and if so how and is it even possible?
post #1772 of 2165
Though a few posters suggested they had, the posts imo were misleading. The qumi is incapable of displaying frame packed, side by side and over/under formats, unless converted to a 120 Hz frame sequential format. An interesting product releasing soon is the 3DFury, looking at the specs, it should work well with the PS3 and Qumi. Keep in mind that due to the low lumen output of the Qumi, it is not very good for 3D.

Thanks 3Dnewb, I have been following this thread for quite some time but at $399, i will have to pull the trigger.

Hi guys, I'm past the 200 hours on my qumi and despite all it's problems I'm happy, anyway I wanted to show you mi ceiling mount installation for my qumi, it's practically finalized so any suggestion to improve it are welcomed.

Muy bien, Espero que lo disfrutes!

I think I said that right, if not I meant---> very good, enjoy your efforts.

What size are you projecting now? Only suggestion I have is just make sure it's getting plenty of air into it. Is it mounted flush to the plexiglass?

thanks alot 3dnewb and yes you said it right (thanks for that effort!!), my diy screen is 106" and there´s a square hole on the top of the plexiglass to let the air circulate because there´s a fan in the qumi, and yes it is mounted flush th the plexiglass.

I've noticed something like a dust blob in the image, is there a way to eliminate this from my qumi?
post #1781 of 2165
Good question, I recall someone saying that the complete optical path was sealed. I'd call tech support, whatever you do, don't smack it, to try to dislodge it, especially if it's still hot.

You can try changing the background to one of the solid colors, I think if I remember right, it had green. Then from the side try to observe if there's something on the lens (there will be reflections from the light that look odd), but never look directly into it while it's on. If the light path is not sealed, canned air can be used to blow it out, but only when the unit is completely cooled off.

Ok 3dnewb thanks for the advise, I'm totally new in this matter so, I'll check the projector and look at the thinks you are mentioning.

Hi, i need your help..

http://www.avsforum.com/avs-vb/showp...postcount=1197

Does this 120hz trick work with dualprojection and 2560x800 resolution ( eyefinity ) ?

Not interested in 3d, just fluid widescreen gaming @ 120hz
post #1784 of 2165
It works for Nvidia 3D Vision, comfirmed.

What can you accomplish by removing the Identification Pins from a VGA addapter/cable and connecting to a AMD GPU, I've no idea.

Basically what you do by removing those pins, is hide your display from the GPU, it essentially can not see the display and comfirm what type it is. So it defaults to saying it is a CRT. At which point, you create a custum resolution.

Does eyeinfinity work if it sees what it thinks are 2 generic CRT Displays? I've no idea.
post #1785 of 2165
I'm going to build a new PC rig, the decision if AMD or NV for graphics isn't final yet. I would chose Nvidia but afaik nv surround doesn't support dualprojection, it has to be tripleprojection as minimum if you want to expand your FOV. Things could have changed with new drivers, dunno...

Thx for the help anyway.

Can you use IR glasses for 3d with the qumi cause I know there is an option in the 3d menu. If so, which glasses and do you need an IR emitter. How does it work. PLEASE HELP! DLP glasses are too expensive in Canada.
post #1787 of 2165
Well yes and no. The Qumi allows you to turn off DLP Link if you are using IR glasses, otherwise the image can appear to be washed out due to the "white flashes" that DLP Link glasses need to sync.

But the thing is, for IR glasses, you need a 3-pin mini-DIN Sync Out to plug the emitter into.

So you'll need a device with this feature, such as the 3D-XL or 3DFury.

You do know that the Qumi will do 3D, but it will be dark, as such the room needs almost 100% light control?

Also, you do know that, you can not view 3D from sources like a stand alone 3D Blu-ray player, Set Top Box(Broadcast) or a PS3/XBox 360 without a converter. But you can playfiles from your computer through a stereographic player.
post #1788 of 2165
3DNewb..thanks for the heads up in regards to the $100 off on the Qumi. I figured it was now or never to jump on getting my first projector... Sadly enough I had to return it today for a replacement as I was really disappointed in the color reproduction.

Admittedly I do not know much about projectors period. I have followed the Qumi and this tread since last January so I am well aware of the strengths/limitations of the unit. Still I felt something was wrong. The first issue was fan noise.. OK I lied when I said it was my first projector, I have been using on occasion an old dinosaur Sharp from 1995 or something like that (discarded from my school), that thing sounded like a turbine when running and I had to believe anything newer would be better right? I noticed the different modes on the Qumi, User/TV/etc produced a different fan noise level however I have to believe it was still way too loud for people on this forum to not be complaining about it.

Second, and most importantly, was the wicked horrible color reproduction. I used both HDMI and VGA inputs on both a laptop and desktop for redundancy purposes.. The image not only displayed the green tint some people were complaining about but the reds were also really really red.. I mean red on my monitor was bright pink through the Qumi. I also could not achieve anything remotely close to "white", the best I could get was a dirty yellow haze, i.e. backgrounds of MS windows. Please tell me that is not normal? I know screenshots are subjective but to me the reds didnt seem that intense..

Using the HDMI through the Catalyst Manager I was able to adjust the Red/Green/Blue channels and found that sliding the Red/Green 0-100% produced expected results however sliding the Blue channel resulted in no change whatsoever. Pardon my lack of understanding with LED DLP projectors but this leads me to believe that one of the three color filters was defective from the factory and hopefully a replacement would fix the issue..

Nothing is more frustrating than wrestling with a purchase for months and then being let down when you finally pull the trigger on it! At least the retailer has an excellent return policy.

Hi

I received my Qumi today and want to connect to my DVD player via the AV in connector. I purchased a A/V (Yellow, red, white Connectors) to jack connector (not the Vivitek Original) but I cannot get a picture/sound from my DVD player on the Qumi. Any suggestions of which cable to get? Can I use a A/V to HDMI cable?

Thanks
post #1790 of 2165
You need the RCA cable from Vivitek, it's proprietary. Contact them through their support email or Facebook and provide them with a copy of your receipt and they'll send it to you.

anyone selling this PJ for 399 still?
post #1792 of 2165
Not currently that I'm aware of, although the Acer K330 is 499 at Newegg until tomorrow (LED 500 lumens). One thing with Newegg NO REFUNDS, Exchanges only.

http://www.newegg.com/Product/Produc...pk=acer%20k330

If interested, there's a thread on it http://www.avsforum.com/avs-vb/showthread.php?t=1344147
post #1793 of 2165
3Dnewb yeah I keep thinking that the fan noise would bother me with that unit. What do you think?I notice you are very active on the threads I have been reading for a on the go projector so I would love to hear your recommendation on what you where buying if you where getting it for xmas. Thanks for all you do!

Well I like the Qumi a lot, watching movies like Nemo and Speed Racer, were stunning due to the vivid colors they have. The only drawback of the Qumi is a lack of lumens, it pretty much needs to be used in a semi-dark or darker room.

I'm not sure on the Acer K330, I have the Viewsonic PLED-W500 now, due to the fact that it supports 3D at 1280x720 via HDMI and has more lumens than the Qumi. Myself, I'll gladly put up with fan noise to avoid lamp replacements and fretting over hour accumalation.

But there is plenty of information in these forumns to make a decision for yourself. I know I was concerned about fan noise after seeing the first few videos posted of the 500 lumen LED projectors, where they sounded like a vacum cleaner, but that's not the case. They sound more like those little portable space heater fans humming away blowing hot air in the room.
The fan to me, is a little louder than represented in this video, but it's a good representation.

post #1795 of 2165
So if it was your money and you where going shopping right now the w500 would be the one you would buy?

-P
post #1796 of 2165
Yes, because I use it for gaming in 2D and 3D PC gaming.

For watching 2D movies/gaming I loved the Qumi, for 3D movies/gaming, it was a lil dark.

hard call to make a 5360 and 2 bulbs and a w700 and 1 bulb both will get around 12000 hours at 650$ and are so much brighter.
post #1798 of 2165
Aye, but there are many other things to factor in like electrical use, cooldown times, portability, color wheel failure, predeposition to RBE, gradual lumen loss over time, etc....

I just don't want to be the guy that is on his 3rd bulb by the 700Hr mark, like this poster http://www.avsforum.com/avs-vb/showt...3#post21332103

Or this guy with 400 Hrs http://www.avsforum.com/avs-vb/showt...0#post21343120

There can be any number of factors leading to premature bulb failure and these two posts I linked are more the exception than the rule. There are plenty of people that use projectors with lamps and are quite successful in getting the alloted hour rating out of the bulbs.

But I'll stand by my statement "Myself, I'll gladly put up with fan noise to avoid lamp replacements and fretting over hour accumalation".

But that's "me"

Individuals need to make their choice based on their needs and applications.
post #1799 of 2165
Bingo. And I don't want my living room to look like I have a fruit juicer on the table or a fruit juice hanging by the ceiling.

In pure darkness, I find my LED PJ to be too bright sometimes and that it sears my eyes (I'm light sensitive). No way in hell would I watch a normal PJ in darkness.

have you seen a fruit juicer or a bulbed pj beforeya 300 lumens can be sooo bright?tripod mounting still?

this is all forum fud really,If any of this was a real problem they wouldnt sell any.As any one who has used a PJ for presentations
knows even the 500 lumen led pjs would never cut it.
