LG PA70G LED 1280x800 700 Lumens. - Page 72

1. Tried the "unhook hdmi" and change settings. This does NOT apply when you then attach the PC via HDMI.

YCbCr or RGB

Well, I don't have such an option on my limited Intel graphics laptop. . . So, then I'm SOL?

Oddly enough I don't/didn't have such problems with the BenQ W1070 or the previous LG LED HDTV we tried.

Not going to be happy if I cannot adjust colors when hooked up to a PC, especially since they didn't bother with a decent audio out on the 75U.

Well this custom monitor inf has been a total pain in the butt (the one rugrash posted several pages back). Not only does it not do 3d at 1280x720, but now it has 1280x720 as the 'recommended' resolution, so it switches to that when I swap my displays (annoying, I would rather have 1280x800 as default for non 3d viewing). I tried updating the driver and selecting the 'generic plug and play' monitor (I assume that's what it was using before, because I never installed anything from LG, but it STILL shows up as "Viewsonic EDID Override" in my display dropdown (and still suggests 1280x720 as the recommended resolution).

Has anyone been able to get 3D working in a non distorted resolution (something besides 1024x768)? Yes I know there are probably some people in the past 71 pages, but if you could just explain the steps real quick that would be much appreciated.

Thanks

*been digging a little, and on Page 36 tataniko said - "I have no problem with 3D at VGA 1280*768 resolutio", he also implied there is a limitation on hdmi and thats why it cant do more than 1024x768, but then another user claimed that is not true...

I really don't want to run a vga cable up to this thing just to get a little better resolution.. there must be away to enable other 3d capable resolutions via hdmi...

I got 3d to work just fine( just an FYI i find 3d on this projector is not that great compared to my 3d plasma but it does work on the pa70g) anyway I have a nvidia geforce 610 graphics card and you have to go into the resolution setting on the graphics card and do the custom setting. I was able to set my to 1280 x 720 @ 120 hz via HDMI and it worked just fine actually it was better then the one recommended in the lg manual of 1024 x 768 @ 120. here are the step I used open the graphics card control panel and go to display and then change resolution, next I went into customize, then towards the bottom of that screen is a create custom resolution button (above that is an area to enable custom resolution not exposed by the display and you have to check it. now go into the create custom resolution and create the resolution you want and test it and it should put it in your list of resolutions on the main resolution screen , select the resolution your just created and it should work just fine. if you don't have an NVidia graphics card then i'm not sure ,but it should be pretty much the same. good luck and hope this helped.
post #2134 of 2305
Last night we watched a few shows on our 75U. . . after I readjusted brightness, contrast, gamma, etc. . . — realized that the brightness on this thing doesn't really calibrate to best viewing. When I run my white/black clipping video, adjusting brightness to make it accurate results in brightness being much higher than needed. If I pick a dark scene in a movie and then readjust it, I find I'm about 10 points lower with the same amount of shadow detail. The LG picture wizard had me at ~63 (a bit lower than the clipping video) on brightness and I've found that 54 (can even go less) is actually fine for video via HDMI. Also noticed the picture looked much better turning brightness down from the wizard's recommended — so, all in all seems better to readjust via a good video, for me at least.

Focus is clearly off from top to bottom and seems to either change or need a significant amount of warmup.

Now for color adjustment via the PC since HDMI gets no love!
post #2135 of 2305
Has anyone else noticed if, while focusing, the lens/image shifts — the image will move about 1/2" during focus. It will move when you approach the end of the focus ring's movement in one direction and then move back when you focus in the other direction, but only after you've moved the ring a good amount backward.

@thebigdadye

Thats great news! Are you sure you were able to actually enable 3d mode while in 1280x720 120hz hdmi? I can get mine to go 1280x720 120hz via hdmi when using that custom monitor inf, but it will NOT allow me to enter 3d mode.

Now we just need to figure out how to do similar 'custom' resolutions in the ATI catalyst control center. I dont see any options though (its just a pre defined list of resolutions...).
post #2137 of 2305
yep i'm sure I even hit the 3d button on the projector remote and it turned it off and then I turned it back on and it said something like put 3d glasses on. i'm just not that impressed with the 3d effect by the projector compared to my plasma, but it does work.
post #2138 of 2305
Well thats great news! I thought the 3d effect was great in a pitch black room. So now all I have to do is figure out whats wrong with ATI. It cant be a limitation on the card... can it? Im using a fairly modern HD 6900...

The really strange thing is, since installing that custom inf, I can select 1280x720 from the windows screen resolution menu. And if I go into advanced settings, it CLAIMS its running at 120hz. However when I hit the 3d button it says 'mode not supported' or something like that.

Anyone had any luck getting 1280x720 3d over hdmi with a ATI card?

I got a GT 650M NVIDIA Card + HD4000 internal GPU unit. So i doubt it has something to do with ATI / NVIDIA. When i use the 1280x720@120hz custom res 3D is not available for me. Only when i switch to 1024x768@120hz it is possible to turn 3D on. This Limitation is even stated in the manual.
post #2140 of 2305
Hmm.. thebigdaddye, are you running straight from your pc to the projector? Maybe you're running through a avr that is affecting things? What could be the difference between your setup and thomask's?...
post #2141 of 2305
I have mine hooked straight up to the projector via hdmi. if I get a chance today I will try and make a short video to show that I am getting 1280 x 720 @ 120hz to work in 3d.and how I did it. if I don't get to it today I will for sure tomorrow. with your NVidia card you should have the same custom resolution settings as I do on my GeForce 610
post #2142 of 2305
here is a link to a video I made showing the custom 1280 x 720p @ 120hz and 3d on my PA70G projector. to show that It does work. http://www.youtube.com/watch?v=bKBd3JluKok&feature=share&list=UUtp7k1KKCj6s3duaj-u1gnQ
post #2143 of 2305
Cool thanks for the vid! So did you have to download any special drivers, install any custom monitor infs, or do anything funky to get the option to select 1280x720 120hz in the nvidia control panel?

Seems so strange that there has been SO much back and forth (like 70+ pages) of people trying to figure out how to get this to work... Whats going on?...
post #2144 of 2305
It's been discussed here many times and many of us had it working, all of the info is here in the thread if you are searching for it.

I had 1280x720p @ 120Hz working as well (via VGA) but it was not in proper aspect/1:1 pixels (just as the above video shows) and as such it was not truly 1280x720. wink.gif

Interesting i wonder what youve done to make it work. I dont see a difference in the Panel compared to mine. I got even the better GPU. But i guess the Problem is not the GPU. Do you use a HDM 1.4 or 1.3 cable? Any other mod or different inf file you used? Please help us to make it work like it does for you.

@DaGamePimp what do you mean by not 1:1 ? Does it has the same unsharp look cause it gets scaled anyhow? I couldnt see that on the vid cause of the low cam quality.

I tried 2 different HDMI 1.3 cables and no difference.
post #2146 of 2305
What I mean is it is not running at 1280x720p @ 120hz, the scaling is wrong and thus the aspect ratio is wrong, it's not proper 16:9.

1280x720p @ 60hz has proper 16:9 aspect ratio.

I'm not doing anything special, I have the latest update for my gpu, a regular HDMI cable. the only thing I do is go into the custom resolution settings and make a custom resolution and save it, then select it to display. it says on the gpu screen if your display can display it it will otherwise it will not display an image. I am not sure if it is 16x 9 but I do know the picture shape looks the same and it's seems sharper/clearer when in 1280x720 @ 120hz. maybe your ati card is interfering with the NVidia graphics card , maybe you will have to disable the ati card. good luck.

how is it not running 1280 x 720 @ 120 ?? I checked it and versified it in the graphics display settings it is 1280 x720 or the display image would not show up according to my graphics card. it would reverts back and I know this because I have tried on other displays

Which ati card are you talking about? I posted that i got a NVIDIA GPU + Intel HD4000.
post #2150 of 2305
Yeah I'm the one with the Radeon HD 6900.

@dagamepimp

Were you using a custom monitor inf? If so could you post it again please? I tried installing one that rugrash posted and while it allows me to do 1280x720 120hz, it will not allow me to enable 3d mode.

Short of trying a vga cable, I have no idea what else I can do frown.gif

Even though you are sending 1280x720p @ 120hz and the projector picks it up as such it is not scaling that resolution properly at 120hz, look at the video that was posted and you can see it is not a proper 16:9 aspect ratio (even though 1280x720p is 16:9).

As I said I was using VGA, I could not use HDMI as my AVR would not allow me to pass 120hz.

The monitor .inf that I used for VGA is posted in this thread, I posted it. It was for the Acer 5360 but it works with the PA70G via the VGA connection.

The monitor INF files are either digital or analog meaning the digital version works on HDMI / DVI-D or the analog version works on VGA / DVI-A.

I'll look for it and post a link here if I find it... Acer_H5360.zip 1k .zip file

post #2153 of 2305
I am wondering if anyone knows that the LG PA72G (EU version) got the same 3D function as LG PA75U (US version). I have checked the spec here http://www.lg.com/de/service-produkt/lg-PA72G but it doesn't mention about supporting 3D signal with side by side via HDMI. However, it does mention about WiDi and DLNA wireless function with PA72G. I am wondering if PA72G is the same version as PA70G but only supporting Wirless connection additionally. I have checked different LG web sites and there are only 3 models (PA75U US version, PA75C China version and PA75K Korea version) supporting 3D signal with side by side via HDMI. I am living in UK but those models didn't release at all. Also, I would like to like to know if any PA70G user here who can update their device's firmware to support this function?

Thats not easy to answer for me since im more an IT guy but a projector geek. Here are some others around like Pawel, rgtaa, DLPProjectorfan, DaGamePimp etc who are more into this than iam.
But as far as i know you have to know about the following points:

- Sharpness (which shouldnt be an issue with proper glass lens focus + lcd panel technology)
- Real Brightness Output (not the theoretical brightness of the inbuilt technology) needs to be measured by someone
(for example the Acer K750 which is listed as 1500 Lumen only has 600-700 after testings when i remember correct, so the same as the PA70G)
- Resolution: is it really 1280x800 natively or does it only support this resolution?
- Convergence/CA: most of these cheap no name projectors are having hardcore convergences ive seen. Even the PA70G has this but not as extreme in my opinion.
- Colours: is it possible to get near to D65K colour temperature best seen when compared to a TV or anything else which has the correct adjustment.
- Cooling / Loudness: does it have a closed cooling path where no dust can get inside the lightpath? How loud is it at which brightness setting?
- Contrast/Black: LCD panels have lower contrast and blacks naturally than dlp and you have to ask what solution they use for the dynamic contrast. Pulsing didnt work too good on the SP-F10M and i dont know how an iris would work combined with LED/LCD lightpath. But still if it is near to 4000:1 it should be enough considering the negative aspects of dlp such as rainbow effects and other possible eyestraining issues.

Id say if you can send it back try this Egate 512 and compare it to another known projector and post your subjective experience. But for you being sensitive as you say when it comes to quality i doubt this Egate can compare to even the PA70G which is probably the best all around LED HD Projector if sharpness is not too important for you and the price is around 400-500$. Im only not happy with it cause i payed alot more. For 399$ or even 499$ i would be very happy with the PA70G even with its flaws.

My HT dream still is a LED Full HD Epson LCD Panel 1500 Ansilumen projector with working dynamic contrast by the pulsing of the LEDs but controlled by better chips (each for every LED).
My 2nd HT dream would be LED Full HD DC3 DLP 1000 Ansilumen projector without a colourwheel for green and proper cooling"

Your prompt Answers encouraged me a lot a few Months back and I was hell bent on getting the LG PA70G.However that didnt prove to be easy and I had to finally buy the Egate P515 for the simple reason that after so much Research I got only A few sellers selling the product and I could not even find it in the Capital.Poor Network of the LG Company for the Product here in India and the fact You all guys said about some focus problem,The purchase in my opinion was definitely going to be a nightmare If I were even 10-15 percent unlucky.
It has been around 20 days since I bought this Pj and I am Reserving my verdict on this One,for till now I haven't got my Screen.May be i will Post something if you guys would like.By the way,On Your parameters,I have till now been able to get that Contrast is Good of this PJ and Loudness is not that much.My walls painted with Lime didn't produce great image quality,A thin piece of Cotton cloth produced much better image.But I m yet to get the quality i was talking about.Let us see after I get the Screen today.
post #2155 of 2305
Hey folks, since it's almost the same projector feel free to try these on you PA70Gs and tell me your thoughts:

Brightness: 83
Color: 51
H and V Sharpness: 38
Color Temperature, found under "Expert Control/White Balance": Purity
Black Level, found under "Picture Option": Low


Also I suggest a bright grey screen instead of a pure white one, this is after I compared the results with both and to give you an idea of how it looks:



BUT this is a bad example and one I found on the web so on the PA75U the whites are perfectly maintained.

And as I mentioned it has to be a very bright grey screen but noticeably not white.

Feel free to leave feedback on my posted settings but please try them first and then tell us.

Anyways, enjoy!

Now for my question, I have the HDMI cable running from my pc to the PJ but "TruMotion" is still disabled, can anyone help me understand why?

Those settings will not follow over onto the PA70G, there are variances between the two models. wink.gif

post #2157 of 2305
Well I just ordered a long vga cable, so hopefully that will allow me to do 3D at 1280x720.

Still curious if anyone knows what needs to be done to get it to work over hdmi....
post #2158 of 2305
I ordered a PA70G too, after the PB60 was really sucking with his lense i hoped I had luck to get an actual built of the PA70.
While I unpacked it, I looked atr the back and I was happe cuz there was written Jan 2013, but after testing I wanst anymore.
I got a bad uneven focused unit with a focus limit on 90". That was really annoying.
If it was an earlier built, I would have tried that thing with the screws, but I took the fact that the people here were reporting better focus on 2013 units warned me like a wink of fate.
I'm looking now for a K330.

I wish you better luck with the k330. Let us know how it works for you. It's good to hear the comparisions on the LED's and you would be getting a new build date.
Yeah, it's still hit or miss with the PA70g/PA75u if you get a focused unit or not.
I don't want to repeat myself, but, newbies when addressing the focus issue on buying it, on first time setup and for testing purposes, place the PJ 4 feet from ground (on tripod or table) and about 8 feet back (80inch screen) , directly centered with the middle screen, not to the left or right, dead center and turn off auto correction. Check the uniform focus in that mode ONLY!
Once you figure out you have "focused unit", then if you place it in ceiling mount or other less optimal placements you realize it's just placement that is causing the slight unfocused upper corner or lower corner unfocus. Some people overlook the basic's and think they can mount it anywhere and it should be in focus top to bottom, left to right, not so.
If you got a focused unit after correct testing, than maybe look at opening up the unit and doing the dagamepimp's guide on adjusting focus wheel.
post #2160 of 2305
Hi All,

Could you please write one by one custom settings for pa70g for best resolution. And settings version info vs.. for steoroscopic player. I tried a lot of thing to solve jittering problem but I could not.
Thanks,
