ACER K330 LED 1280x800 - Page 29

I'm using my K330 straight out of the box. No monitor file. Just the latest Nvidia beta drivers and a custom resolution of 1280x720 at 120Hz. Oh, and I am running DVI to hdmi to the K330.

Tataniko, thanks for the time you've spent experimenting with 120hz and 3D timings for these LED projectors. I just might hop off the fence and order an Acer K330. I'd like to connect a PS3 -> 3dxl -> edid spoofer -> Acer K330

DonBrutto, nice job
please use the monitor asset manager, and create a monitor.inf file for us.

Sisyphus, edid spoofer sounds great, can you link any url?
Also, you have to check the new generation cheap 3D converter, probably they offer more possibilities than optoma/viewsonic:

Ok, how do I post the file?

The custom resolution that you make in the Nvidia control panel will not show up in the EDID, so no sense posting your inf.

There are several users that have had success using a 3D-XL with their PS3 by just using a cheap HDMI to VGA converter.

If you were to get an EDID emulator, I'd recommend the DR. HDMI, it allows user programming of custom EDIDs.

Windows can overstep EDID information, because we can use custom monitor driver with custom resolutions, and achieve all potential resolutions for free.

We have be careful when using third party overpriced controllers, which is based only one chip solutions, because many times these companies are misleading the costumers.

3D is more than 150 years old, so there is nothing new, only entertainment company tries to make more profit time to time, now-days the selling of DVDs and HDs started to fall down that's why we have to step into the 3D age again.

Only one important invention happened 60 years ago, Hungarian Gabor Denes developed the Holography, but at the moment, our technical skills are not enough to produce any good commercial device.

So, be careful with 3D marketing, we have to go forward and must attain the Holography screens first....

He is not using an EDID override, he is using a custom resolution profile that is enabled via the Nvidia GPU driver.

Video looks really great through dvi to hdmi at 120Hz but no 3D, so i hooked up my DVI to VGA cable and it works great! I can play borderlands 2 via iZ3D and watch 3D movies with bino. I have never seen 3D before and this is wild! There is no magenta push either. Is there a loss in quality using vga vs. hdmi? Also I set a custom resolution in Nvidia software again, this time using "CVT Reduced Blank" instead of "Auto". Anyone know of a solution for 3D gaming for dlp after iZ3D expires? I would rather not reinstall windows every 30 days.

So doing a little research on this for myself as well...it turns out that for your Nvidia graphics card to output a 120hz 3d signal for gaming, blu-ray, etc, it needs the 3D vision emitter connected (or additional software like iz3d or tridef). This is purely so Nvidia forces you to buy their 3dvision emitter and glasses.

Neither the emitter nor the glasses are actually required for 3D output if you already have dlp-link glasses. The 3dvision emitter just acts like a software license, telling the Nvidia drivers it is OK to output a 3d signal.

Fortunately, you might be able to use this emulator to trick the Nvidia drivers into thinking the emitter is connected:

Good luck!

does ATI do any of that, require you to purchase their brand x equipment to get 3d working? Just wondering if purchasing a new video card to do 3d with one of these led projectors if it makes sense to go with ATI over NVIDIA .

For the price of the 3d-xl , I could just buy a new videocard. But you probably can't run a ps3 through a pc to get 3d.

The problem with the Nvidia emitter emulator is that it no longer works after the 275 drivers as far as I know, unless it been updated/revised to circumvent whatever Nvidia did to disable it.

If you buy an AMD GPU, you'll need to buy TriDef to use for 3D gaming. You can get it at half price though with a Radeon card, but it will not work if you remove the Radeon and install a Nvidia card.
http://www.tridef.com/cart/product.php?productid=46 (has all the features as the full priced version, but only works with your Radeon card)

I recently went back to my DVI to HDMI cable and set the custom resolution to CVT reduced blank as well and it works too! I can watch 3D movies and play iZ3D games.

You also need to use a .inf EDID file from a Nvidia 3D Vision Ready projector.
Otherwise, Nvidia graphic card driver will not allow you to do 720p 3D with a non 3D Vision Ready Acer K330 even if you managed to create a 120Hz custom resolution.

You will also be limited to the 3D resolution of the Nvidia 3D Vision Ready projector the EDID file come from.
It seems that most of the 3D ready projectors do no more than 1280x720x120Hz in 3D.
That is lower than the native resolution of the K330 (1280x800).
Only one projector, the NEC V300X, seems to be able to do 1280x800x120Hz in 3D but I did not find any EDID file from this projector.

If someone has access to a NEC V300X, please make an EDID file from it and post it here .

Hi guys. How do you think is it worth to buy K330 right now? Need inexpensive LED projector and my choice is not great. Optoma ML500, Vivitek qumi 5.

I will choose the latest model of 500 ansi lumens LED instead of K330. Have HDMI signal drop issue been resolved?

BenQ GP10 or Toshiba SDW30 might be another alternative choices.

No reply :rolleyes. Well anyway i'm focused on K330. The final decision i took after reading review here - http://www.projectorreviews.com/acer/k330/index.php.

hey guys someone in my area is selling a used acer k330, he wants $460, what do you guys think. He does not have the receipt so i dont know if the warranty is still valid he said the he never registered it. He has had it for a short while and says it is fully working.
- are these units reliable?
- if something happens will acer still cover it?
- what if i make a receipt and use that to register, does that receipt need to be from a authorized dealer?

Dangur, I have owned and used an Acer K330 for a year now (since November 2011), and so far, the projector has performed impressively well. I (and my friends) have watched a great many hours of HDTV, blu-ray, and DVDs on the Acer and enjoyed the experience.
I project a 120" image (16:9 diagonal) in a light-controlled room and the experience is, in my opinion, cinematic. I would check amazon and other retailers (both brick-and-mortar and online) to verify if a new Acer K330 is available for close to the asking price of the used one you refer to, in which case, I'd just get a new one. If you could meet the person selling the Acer K330, and he or she could demonstrate that the projector being sold is, in fact, working, then you could make an offer for less than the asking price because that's just the normal process of negotiation! (For example, I'd offer $360 IF the Acer demonstrably works, then after some back-and-forth settling, actually pay $400, that is IF it works.) No, I do not think that Acer, nor any manufacturer, would honor any receipt that is not from an authorized dealer, so I would think that making your own "receipt" would not have any validity, warranty-wise. BTW (by the way), I like your icon "SWAG", an acronym for "Stuff We All Get".

Thanks RonKnox for the quick reply.
I do not know how the seller will react to me offering an lower price as he originally wanted $500 for the unit. I live in canada an i cant seem to find the k330 anywhere at a close price. most places in canada want about $560 plus tax. I can order form the states but i would have to pay costumes on fees which seem to be $60-80. I was also looking at the acer k130 which it seem i can get either from eBay or from a site called HBphototovideo for about 500 with taxes and shipping thought this is a lower lumen projector. Also there is a store in canada sell the Ssus P1 for 450 after tax and shipping though this projector does not have an hdmi input which might be a little annoying in the future.

I have read through this thread and it seems that some people have had issues with the projector having signal drop and one user had an led blow. does anyone know if these were only issues with the older original makes ? Are allot of people experiencing failure?

PS. Im glad the you like my icon, i didn't know that swag stud for that

Why option Dynamic black is not active? How to make it work?

Hi DonBrutto, how did you manage to activate 3D on your Nvidia GT440 card? Did you have Nvidia 3D kit (IR transmitter and shutter glasses) or just used IR transmitter emulator?
And something interesting, this week I had frame drops via HDMI for the first time since I bought the K330 in December last year. Guess what, there is no problems with the projector's HDMI port, frame drops happened after pulling out the cable from the projector a few times because of some dangerous thunderstorms. By cleaning the connector on the cable with contact cleaner spray, the problem was fixed, no more frame drops.
After reading Tataniko's coment about the LG PA70G, only because I trust him, I decided to buy one yesterday and all I can say is: wow. I am blown away, the LG is in another class.

I have an Acer K330, and I asked myself the same question as karma, about how to turn on Dynamic Black.
Since the feature is stated in Acer's product description, and I can find no setting for it on any menu option, I am reasoning that Dynamic Black is a built-in feature that is always "ON", though manufacturers (not just Acer) have been known to make mistakes in their own product information. I believe that I would have Dynamic Black turned on all the time anyway, because I want deep blacks, though I normally would want to have the option to select a feature or not, even if it's just to see (and appreciate) the difference.
So, karma, I think that you are seeing the Dynamic Black active already, it just doesn't appear on any settings as an option to turn it on or off. Does anyone know anything more for certain about the feature?
I have already enjoyed many hours of HDTV (via external tuner) and dozens of blu-ray and DVDs on my Acer K330, Dynamic Black or not !

Black is not black at all. That's a problem - very distracting. Pj shine like a hell and i just can do nothing with it. But i got an idea. May be a good point to use Neutral density filter (ND2 or ND4)?

Hello Tehen. I purchased an Nvidia emitter and 3D Vision would not see my display so I tried the H5360 inf file and it gives me "Input not supported" and shows me the acer red screen over hdmi. I am able to enable 3DVision over VGA though. Any idea why this is?

Update: I figured it out. Now I have 3D over hdmi!
Edited by DonBrutto - 11/30/12 at 10:47am

Yes I just received a refurbished emitter and after reading colmania and Tehen's posts I have it working over hdmi!

Thank you for your feedback.
I am glad my comments helped .

well shucks, I came over here looking at the k330 because over in the lgpa70g every other post is b#ing about focus issues. Think ill wait for Ces and see what 2013 has to offer.

I absolutley love mine i use it for home cinema and on the go ive made two videos of it for ppl to look it might help you decide what you want

Could someone please tell me how i get to the k330´s factory meny? Thanx
