if you compare the shoots of the optoma and the acer you can clearly see differences. in terms of ca acer is not as off as optoma. focus drift is not an issue with the acer because of different exhaust. i doubt nec will do it better, but because of the differences theres still hope. so plz read/inform before posting next time

Do you actually own either of them? The exhaust/cooling layout is the same (seen from the front, inlets front left and the right side, outlets front right by the lense and rear left corner), the acer does have focus drift and the CA seems about the same to me.

there are measurements clearly showing that k330 and nec l50w are the only ones out of the clones where the hottest exhaust is away from the lens. the others have the hot exhaust right next to the lens. no ones reporting focus drift for k330 so far. so you have k330 and stating it has a focus drift? that would be contradictory to the zol.com measurements.
if you look at the cross pattern picture taken from the optoma you can see that for example green is about 2 pixels off. the cross pattern picture taken by you shows that green is about a half pixel off. i appreciate that you share your experience with the device but once again plz stay correct with information. you can cleary see differences in therms for ca.

Hello guys!

As I already said, got my K330.

It is very small. Just for some testing, I projected a 135" picture on a BROWN wall!

In front of the wall in the hughe box, is a nice 135" screen. In a few days the projector will be on a ceiling and the screen on the wall.

I am very suprised how well the projector performs on that brown wall @ 135".
It is bright and the colors are nice too. The pictures are not showing the true quality. In real, it's brighter and better.

For a cheap HT setup, it's perfect imo.





Left side is now an a blank wall. It turns to a very nice brightness and color. Contrast is good too. As I said, don't let you fool you from my camera.

Could one of you please try to add the K330 to the Nvidia 3DTV Play supported list, via Nvidia's instructions here http://nvidia.custhelp.com/app/answers/detail/a_id/2774
post #216 of 933
Nonalcoholic, how do you find the picture sharpness and do you notice much CA? And just to confirm, is there any focus drift?
post #217 of 933
I also would like to know if there is any focus drift or change. Seems like it's down to this or the nec.


How far back did you have to be to produce the 135" picture?
post #218 of 933
Here the Acer is actually more expensive than the Optoma, so as of right now, the only reason for me to choose the Acer over the Optoma comes down to the focus drift. Comparing the rest is very speculative and subjective. Unless of course someone has the two units side by side.

I'm still gonna wait out for the NEC and see what happens there, but that's a premium price. The exhaust system between the NEC and Acer seems identical, so if users of the Acer are reporting focus drift, then it's probably safe to assume that the NEC will have too. And that alone for me wouldn't warrant that premium price. So can owners of the Acer report if there is any focus drift? Thx!

he states it has, but hasnt responded to

"so you have k330 and stating it has a focus drift? that would be contradictory to the zol.com measurements."
post #220 of 933
Yeah I read that, but oddly not much people have complained or commented much about it. Then again I know not many people have the unit. I just want a definitive yes or no, cuz it plays a big if not biggesst part in my purchase.

Yes it does. It settles after a few minutes here though, so it's not a big deal to me. I just leave it at the "final" focus and just let it be until it settles instead of refocusing.

I'm not sure what the "zol.com measurements" are that show it doesn't have focus issues, but I suspect it depends a lot on the environment.

Thanks for the invaluable reply!

I'm in the middle of ordering an Acer k330. I'm getting it from Hardwarehouse.de via the Vorkasse option. It looks like you have to wire transfer the money to them after you order the item. I have never done this, usually you just enter your card data and that's it. So...can anybody confirm that this is legit? I know this might sound silly, but i have lost money on online purchases before, so...

It has become a pain ordering from Germany lately. I have friend in Berlin I often visit, so I have my orders shipped to her when possible.

You could try asking if they do "Nachnahme Lieferung" it will properly cost you about €15 extra. Vorkasse zahlung sucks. yes, you have to wire/send them money in advance. By Nachnahme you pay the courier who brings your goods

Forget this comment, I just got an answer.
post #226 of 933
I have a Qumi, but I ordered a K330 from Germany yesterday.
I think, it is a huge step for me, because
- same price in EU
- two times brighter,
- louder speaker,
- better media player,
- on/off remote,
- auto power off
- optional Wlan
- built in a/c adapter
- include lens cap and all accessories
- 2 years warranty
post #227 of 933
It's necessary to edit and update Acer VGA EDID information to 1280x720@120hz like Qumi, because it has only 1024x768@120hz.

It's okay as long as you're aware that it will not play the x264-encoded 720p H.264 MKVs you can "find on the internet." All you can play then is standard definition stuff (which looks crap on a big screen) and things you custom encode yourself.

Not sure what you mean by all accessories. It comes with a short VGA cable, a 3.5 mm A/V cable and a composite cable. None of these are of much value, really. The lens cover I guess is nice, but if means you have to keep readjusting the focus every time you use it since it's not that easy to get on and off without accidentally turning the lens. Not a problem if you use it in a more portable manner.

Qumi EDID is much better, because 1280x720@120hz.

I'll try it if someone tells me how, but I very much doubt it. It seems extremely unlikely that they would arbitrarily limit it if it could really do 720p. That's something they could use as a selling point.

I think h264 MKVs possible to work well, if you are re index video stream for level 4.1 or below, example with gotSent.

Thanks, that is true, because only 720p@120hz is a blurred and unwatch-able in Qumi, and I guess this resolution is a selling point only, and not true capability in HD Pico.

Probably, but having to reencode everything you want to watch sucks. At that point the convenience goes away and you might as well hook up a netbook or external player.

In normally ps3/xbox360 only support h264 level 4.1 or below, and I guess acer too. Not need re encode any mkv hd to take long time, only must re index video stream and downgrade level 4.1 or below, and it is about 10 minutes. I will try it later sure

I tried all the targets in GOTSent. None work. I'm pretty sure it's the actual video stream it can't handle, not the container. See this video for the actual problem.

Thanks. Qumi neither play nothing, so Acer is hopeful , but I have to wait only a week, thanks DHL.
post #234 of 933
Well, let me know if you find a way to play them without reencoding. I don't see one.

Wow, great! Nice discovering, thanks all.
post #237 of 933
So I'm curious if there are more service menu pages you did not post, or if it's possible to toggle the analog settings page to digital settings?

I also find it weird that the sums of both LED hours do not equal the system hours. Seems the system meter is set a little fast, I call shenanigans.

No. These are all the pages available. There are no digital adjustment settings available. I suppose this might be that the analog-to-digital converter requires calibration whereas the digital signal is always accurate. I don't think the idea is to let you adjust the projector output like you seem to want. I guess you'd have to use the LED calibration stuff for that (or the regular brightness/contrast/saturation/tint settings).

I don't know why. Maybe the system is run at the factory for testing both with the lamp off and on, or it has some intermediate mode after shutdown or it's incorrectly counting the time without an input signal (I can't remember it turning the lamp off after a while when there's no signal, but if it does then that would also explain it).
post #239 of 933
K330 has an intelligent power management, means if no source or idle time, K330 reduce power usage only for Menu at extreme low lumens (70% of Eco). That's why total Led hours and system time(boot time, shut down time, and extreme low lumens) are differing.
post #240 of 933
Still waiting on DHL to bring me my K330...god this is annoying!

Great job with the service menu guys. But...what do we get from it? I mean how can a regular user benefit from being able to access it?
