LG PA70G LED 1280x800 700 Lumens. - Page 35

The LGPA70G info page many times can not understand properly the custom resolutions, works well only with factory EDID resolutions, so forget it.

Throw away your doubt and nightmare, we can easily achieve a real VGA and proper 1280 pixel points with 768 pixel points pictures on the screen, and the built in 3D works well on it.

I am big fan of LG now. I own LG 55inch LM7600 3D TV and then I was searching something interesting for my home theater. LG PA70G was my pick and it is awesome from day one. It plays all the formats that I own from the built in player and it is always hooked up to my ASUS Transformer Prime TF201 via HDMI for the rest of the internet stuffs. The build in speakers are great in sound quality. 720p and 1080p videos are great. No disturbing noise or heat generated from the projector and no problem with the image quality. My setup box has HDMI out and it is a perfect combination.

Anybody compare this to the other LEDs? 399 is an awesome price but a different guy said the black levels for the LG were considerably worse than the qumi q5.

how bad is the chromatic abberation ( green and magenta fringing around things like white text subtitles on a black background, etc.) from a normal viewing distance?

Could you guys test this out.

When you focus at 100 inch screen or 140 inch screen can you focus it and can you go past the focus point on both sides of the focus wheel. Or is it like on mine, when I focus the PJ for 80 inch screen the focus wheel is all the way over to furthest point, and I want to be able to adjust the focus further but can't. I would like some play in it, like at 80-100 inches it's about in the middle of the focus wheel range.

Now, we need a couple of people to tell us, how far the focus wheel goes, I don't want to be limited to 80 inch screen, I would like to know I can use 100-120 screen and adjust focus wheel accordingly.

When you get 100 inch screen size and you have it in focus, can you turn the focus wheel both ways, and have 1/2 inch turn in either way. I don't. Am I alone? If so, I would return my PJ. I like it except for the focus wheel not moving past the focus on both sides of focus, so I can find the sweet spot.

I have asked you if you work for LG or one of its subsidiaries because you APPEAR to have knowlege that is NOT AVAILABLE to the general public.

I ask again. Do you work for LG?

How did you confirm the PA70G "only works WELL with factory EDID resolutions"?

And if that is true then how did you confirm that what you are writing here is accurate?

I have tried with a laptop and 2 different PC's via both HDMI and VGA with no luck getting the unit to properly see 1280x800@60hz or 1024x768@120hz.

The laptop is actually 1280x800 native and via the VGA port in duplicate mode the PA70G see's 1280x1024@60hz, so it appears no 1:1 pixel mapping.

All of these computers are equipped with AMD/ATi Radeon video cards (4650, 5750 and 6970). The 6970 with DVI to VGA adapter would not even detect the PA70G was connected.

* I did notice that going to the input button and changing the Input Label to PC for HDMI changes things up a bit but I have not done any testing to see what all is changed, could simply be an expected level change from limited (16-235) to full (0-255).

My unit is November 2012 built.



This is exactly what happens on mine as well (although I have not projected as small as 80", closer to 100"). I had it shooting on my HT screen at 133" and now mounted in my game room at 115" and in either case there is nothing left on the focus.

It does say this unit is designed for up to 100" so it simply runs out of focal length beyond that point (or possibly sooner). Even so the focus is not too bad at 133" or 115" on mine (although as many have discovered it is not equal corner to corner).

The focus knob on mine has some slight play in it where it will shift the image just a bit.



Verge2,

The black level in my dark walled/light controlled HT is actually fairly impressive for such an inexpensive unit but in my white walled game room it is much less impressive and slightly washed out (which is to be expected).

This was projecting a roughly 133" image on a matte white screen.

Consider it likely that a lower lumen LED model would have a lower black floor.


Roger Lococco,

CA is not bad on my sample considering the cost of admission (let's be honest this is not an expensive lens). I think you are likely to have more of an issue with the focus.




* If I can get everything working as it should (1:1 and 3D) I plan to do a full pro-level calibration on it, otherwise I may not keep it (even though at $399 you'll be hard pressed to best it with any new pj).

** I can also tell there is some input/gaming lag but I have not tested as of yet with crt to verify exactly what it is.

Thanks, good to hear the CA is not too much of a problem.

Do you need anything special to view 3D besides the DLP glasses and the content ? I read some other pj's needed some sort of interface to get 3D like an Optoma device. I use pc for everything,

Thanks

You're welcome but as always YMMV as this can vary unit to unit.


If you can get the pj set properly with your pc (1024x768@120hz) then all you need is DLP link glasses and content.

Jason

Thank You for the fast reply Jason. So does mean it has 1.4 HDMI ? I cannot find anywhere in the manual, I read in the forum it is 1.4 and 1.3 and to my nub understanding, 1.3 you need a 3D device and 1.4 you don't ... is this correct ? Sorry about the noob questions.

Thanks !

You're welcome.

Well the HDMI specs have been 'name changed' but this unit would seem to classify as 1.3, it does not do direct 3D via anything other than a properly configured PC and only at specific resolutions.

The claim that it can do 1280x720p @ 120 hz has not been verified so consider 1024x768 @ 120 hz is likely the only 3D PC option at this point (I am unable to get that working at the moment however so not sure if it is 100% either).

Although I would guess that it will work better with Nvidia 3D Vision as most of the 3D Ready projectors do (of course with Nvidia that means a hardware add-on).

Jason

Jason, just saw your HT slideshow, class all the way !

Thank you, very much appreciated.

Hi all, long time lurker, first time poster. Thanks to all who contributed to this thread. After following this thread for months, I've finally bought my PA70G. This is my first projector and very happy with it. Being in South-Africa, where most technology is almost double the price than in the States, this is the only good LED projector that fitted my budget.

I've got it ceiling mounted projected onto a sheet of HI polystyrene @ 100" 16:9. My focus is pretty good, I'd say about more than 98% uniform and still got a couple of notches in focus wheel left after the picture came in focus. Manufacture date is July 2012. I've got it hooked up to a home theatre PC running XMBCbuntu.

I can set the projector to 1024x768 @ 120hz and set the projector to 16:9 and still fill up and 100" screen and it looks pretty good. I can then use the 3D button on the projector, now I just need DLP-link glasses and content to test. I can get some 3D MKV's from a friend to test, but he told me all his content is in half side by side 3D format. Will this format work with PA70G?

Penquin,

AFAIK this unit will not do side by side, top/bottom or checkerboard.

Which GPU are you using (brand/model)?

Jason

Sorry, but at 15k post over 11 years, sometimes you have to better control yourself doing many spams here, you have read back before your acknowledge tries to destroy other people's word. We are not in the army, so it is not important the ranks and how many years in active. The truth is the only important thing, nothing more. Thanks.

Scurrier achieved 720p 3D through VGA before tataniko, that's why I confirmed again, it works.

Its an AMD 5450 iirc. Then I take it Ill need software or something to convert the sbs format to frame packed/sequential format.

hahaha, it's good joke, I know tataniko, and he is not a stupid man to become a slave or boss of any company.

He tries to research and achieve planet Mars, and he is looking for a proper projector for space environment. Also, he is seriously interesting for a fusion projectors instead of Sun.

If you want to contact me and join, just drop a message with your facebook account, and I will friend you.

tataniko

Doesn't sound like you are from this planet, are you trying to get home to Mars? Is that picture in your sig how the people on your planet look?

Love you bro and your sense of humor.

Now, that the humor is out of the way, can you tell us your equipment that you used to get 3D to work, the computer, graphics card, settings, 3d glasses, etc, all in one post.

I would be interested if someone could post exactly what we need to get 3D working and if we can find "cheapest graphics card" that works, and cheapest 3d glasses. It would be nice to find a cheap 20 dollar graphics card that works, with 20 dollar 3D glasses and free 3d software.

I am looking for budget everything these days. I came across this last night while searching for a card I could afford and read about the older version of this on a HTPC forum

Sapphire Radeon HD 6450 1 GB DDR3 HDMI/DVI-D/VGA PCI-Express Graphics Card 100322L

$39.99 $29.99 after rebate

Product Description

I read on a HT forum these are pretty good for movies, some even like for gaming, and some don't. Personally I like the passive heat sink. Does this look like it will work with our projector ? It is 1.4 and the projector is 1.3 ? And I too would like to know some decent software player to use for cheap or maybe free if possible to view 3D. Either Linux or PC I use both and currently use VLC for everything, and XBMC

peace


Edit: I just found a long review on this card. The conclusion by the reviewer isn't that great for 3D, but I think it was for gaming. I guess if you drive a Ferrari, Lamborghini's then drive a dodge truck. they all work, but you sure can tell the difference between the truck and the 2 cars... personally I am a dodge truck person.

What happens with a cheaper card in 3D, does it lag, do you see less 3D effect, is it to dark, are the colors off, what ?

I personally am not concerned about the gaming aspect of this card

If the people that got it working in 3D can list everything they did to get it to work, we can then see if their are alternatives that could be cheaper, based on the same graphics type card or a better one, depending on how old their equipment is.
We need graphics of PC that has working 3D
We need exact settings.
We need 3d glasses that worked great
We need software they are using

That about sums it up, we don't have to invent the wheel, we just copy what works and these pioneers who got it working can provide links to products/software used (so we don't screw it up and get something that doesn't work). Not sure if the guy that got it working should start a thread or not, just on the 3D equipment for the LG PA70G , but the thread would be based on "working" prototype, and by someone who got it working , the people that are not interested in 3d for PA70G don't have to partake.

Love, wisdom, and humor Here are some previous post, hope helps:

I achieved the most important 3D resolutions over VGA with custom timings and good picture quality. I created a proper monitor.inf file for LG PA70G projector, and this time you can easily switch your projector into any 3D resolutions with any 120hz capable video card. Just easy.

Here are the supported 3D resolutions over VGA:
1024x768x120hz (factory timing)
1280x720x120hz (CRT custom timing) 720p@3D
1280x768x120hz (LCD custom timing)

I can confirm, 3D 1080p films work fine in
- 1280x768@120hz (or 1280x720@120hz) through VGA.

Here is my basic 3D configuration to everybody for future reference (Ultrabook 12watts), which is good for 3D 1080p films experience:

What is this? Something you picked up at a home improvement store? Looking for a cheap temporary screen.

I picked one of these up from Fry's, ordered sunday night and received today.

I went into the only room I can make semi-dark at this time of the day (3:00 PM) and projected about an 80" screen on to a white wall. Very impressed, this is my first projector, but I am going to have some major fun with this thing.

Watched a few minutes of the most recent Star Trek blu-ray and and saw no issues with focus.

Maybe I am lucky, or just don't know what I am looking for, either way, very very happy. Can't want until it gets dark!

So english is not native for you, and that's perfectly fine, but since you obviously understand how to insult in english maybe you should also read what is stated in english before attempting to flame.

I stated that 1280 x 720p @ 120 hz has not been verified, I read through the entire thread before buying this unit and you are the only person making this claim. When you have been asked to prove your claim with a screenshot of the accepted resolution you dodge it with more 'lost in translation' fodder.

When you make claims the burden is upon you to prove them versus insulting others that seek verification.

I tried your monitor .inf file via VGA and it did not work with my gear, sorry. It is possible that units can have variances across many countries and as this is mostly a North American forum I have seen no mention of anyone in the USA getting 1280 x 720p @ 120 hz working with the PA70G.

So before you consider insulting members of this board you should learn a bit about their post history, especially when calling the posts of a well established contributing member 'spam'.

Could you call LG and talk to their tech dept and ask for info on setting it up for 3D in USA, I don't have the 3D gear yet (glasses or graphics card).
Obviously if they say this is "3D ready", someone at LG tested it and can at least point us to right gear or settings.
I believe tataniko if he says he can do 3d, and I think something gets lost in the translation, and also his foreign sense of humor.
He mentioned someone else getting it to work.
Maybe NOW that a few of us have the PJ, we can focus on a few different graphics cards that work.
Did you try all this codec's and other stuff he wrote about.
Maybe LG can help us, if you don't mind, would you mind calling, I would, but , I'm not as good as a techie as you.
I just bought the fx-30 glasses tataniko said work, in 14 days I should receive them, so I have no way of telling if 3D works yet.
Edited by rgtaa - 12/19/12 at 2:18pm

rgtaa,

I'm sure the unit is '3D ready' but I am having no luck with my current unit, although not through lack of effort.

I am going to get a different DVI to VGA adapter for my gaming pc since the current one I have does not even know the PA70G is connected (have to use an adapter since my Radeon 6970 does not have direct VGA).

So I am going to experiment with it more before attempting a call to LG, as I understand it they are not very 'techie' even though they do offer excellent customer service.

I cannot test codecs if the pj will not first accept one of its 3D capable resolutions.

I am not sure how the other codecs will work however since the PA70G is claimed to require Frame Sequential / Frame Alternative 3D (and I am not aware of any mkv/avi/mp4 using that method, these codecs are usually SBS or top/bottom).

Jason

tataniko you are awesome!

could you please help me where i have to place the monitor.inf file?

i have just no idea... i have an ATI /AMD too.

best regards

I'm getting a 150" picture, and I have just a little bit of play left on the wheel. No focus issues that I can see.
