I cannot change everything whats grey as you can see on pictures.

I'm trying to go step by step with you.
So NAME one that you can't click on that is greyed out and doesn't open. I will go to my unit and test if I can do it.
That is what I'm trying to get you to understand. If you read my post, I gave "exact" setting , that was "greyed" out but I could still click on it and it opened for me.
Do NOT speak in generalities, give exact situation, so I can test, that is what you want , right?
Now the only setting I could not change is 3D, but that is because my graphics card in PC will not work. So I did try and every setting that was greyed out I could click on. You did read my post, right? I told you MINE WAS GREYED OUT but I could still change it. Can you do that? Yes or No. And give example where you can't click on greyed out setting.

I set 1280x800 output PC resolution and then I go to the Picture Settings, then Advanced Control (Expert Control). There I can see greyed (Cannot change them):
Dynamic contrast, Noise Reduction, Digital Noise Reduction, Real Cinema, Color Gamut, Edge Enhancer, Whole Color Management System is grey.

Excellent, now we are getting somewhere. Just did it.
You are RIGHT!
BUT, if you click on the top one that is not greyed out, CLICK ON IT, and you can change all the ones under it, it OPENS up another menu, and you can scroll up and down and change all those settings from second screen, dynamic contrast, etc. Check it out.

I didn't know that , but just tried it. So we both learned. Go to first bold setting and it will open up new screen where all the greyed out ones can be changed. Does your unit do the same?

I use Expert1 picture mode. So I click on Expert control, then I see that first item which is already selected is "Black level", but when I click on it and then I list Up or Down, then I cannot select greyed options like Dynamic contrast etc. You can?

ok, it's as I first thought. If you unplug the hdmi cable, and then you are still in hdmi mode, you can adjust all those settings, try it. I noticed the same thing yesterday when I was using the my usb memory stick, If I remove it, then go into menu I can adjust all those settings.

I can adjust them, but when I plug HDMI cable back, then I see everything is OFF again.

Cool, now we are getting somewhere!
I just plugged in my xbox 360 into the hdmi port and all those settings are in black and I can adjust them.
Maybe if 70g sees a PC it uses the settings from the graphic card in PC.
Do you have anything else that you can plug into the hdmi port other than PC, maybe ps3, or blu ray player or something else.

Firmware LG PA70G inquiry
There will be new firmware if more customers will contact the LG support. This Picture mode settings behave really strange. Please contact
http://www.lg.com/de/support/kundenservice-kontaktieren if you have any problems with firmware and they will release new one.

Unterhaltungselektronik (MP): no
Unterhaltungselektronik (MP): for Germany there must be 2 more letter
Honzik1 (me): But it is correct
Honzik1 (me): on cyberport.de invoice there is Serialnummern: ( ********** )
Honzik1 (me): I can take photo of projector
Honzik1 (me): you can see this serial number there
Unterhaltungselektronik (MP): then please contact your dealer... that is a import as i can see
Honzik1 (me): but LG is LG over the all planet, so you cannot help me?
Honzik1 (me): Dealer dont know technical solution for sure...
Unterhaltungselektronik (MP): No, all products are special constructed for one country not for the world , there are many technical issues for many countrys...
Honzik1 (me): Do you have LG PA70G and try that on your model?
Unterhaltungselektronik (MP): No
Unterhaltungselektronik (MP): the problem is i cant make a escalation without a german serial...
Honzik1 (me): so you cannot help me..
Unterhaltungselektronik (MP): no but the dealer can escalate it to the right country
Honzik1 (me): its not so big problem which I would like to solve by sending projector back to Germany
Unterhaltungselektronik (MP): ...
Unterhaltungselektronik (MP): but if you want another firmware what i think could help your dealer can escalate it
Honzik1 (me): why there isnt public firmware?
Honzik1 (me): like on HW300G projector
Honzik1 (me): Can I see the actial firmware version somewhere? I didnt found it
Honzik1 (me): actual*
Unterhaltungselektronik (MP): no

Unterhaltungselektronik (MP): ... i dont know but if there are other customer that want a error done then there will be
Honzik1 (me): ok
Unterhaltungselektronik (MP): Any other questionsß
Honzik1 (me): When I press Still button, it works just for few minutes and then it stop being in freeze
Honzik1 (me): how is it possible?
Unterhaltungselektronik (MP): another Firmware problem...
Honzik1 (me): have you noticed more customers with similar problems like me? Because you said, there will be new firmware if there are problems
Unterhaltungselektronik (MP): no you are the first but this kind of beamer is only 1 month old so there can be more
Honzik1 (me): I have bought it before 5 months, so why you say 1 month old?
Honzik1 (me): I bought it from Germany (cyberport.de)
Unterhaltungselektronik (MP): its an import... in germany we sell it not so long...
Honzik1 (me): ok, really last question: So problems of this projector will solve German team? So new firmware will be made by customer support in germany? Or I have to contact Korea?
Unterhaltungselektronik (MP): You tell it your dealer and i hope they send the information to whereever they buy it
Honzik1 (me): okay
Honzik1 (me): thanks you!
Unterhaltungselektronik (MP): you are welcome
Unterhaltungselektronik (MP): bye
Honzik1: bye

I have just another notebook where is same problem for resolution 1280x800, but there is no problem for resolution 1280x720, I can change Dynamic contrast etc.
BTW even if I can change Dynamic contrast, there is a bug. In the Expert control (Advanced control) menu I see OFF at Dynamic contrast but when I click on it, its set to High, Medium or whatever I choosen before. Do you have same bug?

Do you guys know if it is possible to update firmware via usb port? I hope so, sending the unit back to LG would be a pain.

Ok, if I set my pc to 1280x720, and everything is black, and I can change the dynamic contrast to high, and it seems to stay. Do you mean if I turn off and back on the pc, it will not remember the setting?
I set the aspect ratio to "just scan" and it fixes the screen in pc mode if I set it to 1280x720, without that, I don't see everything on screen.

If they ever did a firmware update, one nice addition would be the ability to shift the picture with wider aspect ratios up or down. So if you're watching a 2.35:1 movie with some serious black bars top and bottom, it would be nice to be able to shift the picture down towards the bottom border so you don't have to look up quite so high. In the Cinema Zoom setting the up/down/left/right controls only work when you zoom in, and the overall picture never leaves the center of the display area. My old Optoma H31 could do that in order to eliminate one of the black borders.

Yes, dynamic contrast stay, but I see off in main Advanced control menu and when I click on it I see the real value. ......for example: I change Dynamic contrast settings to High then I press OK and I see OFF, but when I want change it again and I click OK, then I see High. This settings seems to stay even if I change resolution. So if I want change settings, I have to change resolution first, how stupid. Please contact LG support as I wrote above.

Hello everyone, this is my first post here.

After much reading I decided to go with the LG PA70G. I am upgrading from the Infocus 4805.

I want to buy the projector before mid January. I checked frys today and it's at 499 in store only.

Should I wait and watch Frys to see if they put it on sale for 399 again? Have you guys seen it go on sale for 399 before?

I'm just wondering if I should wait it out or not. It's 600 on amazon.

I have the money now but I am willing to wait a month or so if I could get it at 399.

What do you guys think?

Fry's had it for $399 the entire week following Xgiving, I'd wait and see if it dips down again for Xmas. I love mine but I would hesitate to pay $600 for it, you're getting into 1080p and much higher lumen territory there.

Just so we are clear, the settings work if you stay with the 1280x720 settings, and if you then switch to different graphic settings, like 1280x800, the dynamic contrast stays grey to the same setting as it was for 1280x720 setting, and if you want to change it, you have go back to the 1280x720 settings to change those advanced settings that are greyed out.
Those advanced settings are not really necessary for me with PC since I go to graphics card settings in PC , and get everything working from there. And with 360 all the advanced features work on the 70g, which is nice since the xbox doesn't have a way to change advanced graphic settings on the 360 itself. Yeah, if LG updates the firmware, that would be nice, I just hope it's done via usb, and user can do it. I could be misunderstanding what you are saying, it is a little confusing writing about this. Correct me if I misunderstood what you just wrote.

But at least , both of us can at least get all those advanced settings working on xbox, and PC (if the pc is set to 1280x720). Before we tested this, I was in 1280x800 on PC and we couldn't adjust those "advanced features", now we can in 1280x720.

You understand right, but I tested Dynamic contrast High for 1280x720 resolution, then I switched to 1280x800 and I could see that Dynamic Contrast isnt working. So these settings doesn't stay same over the all resolutions! I just tested it.

I have found probably firmware source code for LG PA70G: http://www.lg.com/global/support/opensource/opensource.jsp

Hello, I am new to this forum and I apologize for my bad English.

I read a number of comments, which claims that LG PA70G is superior to Acer K330/Optoma ML500/ViewSonic, and PA70G is in another performance league.
I want to share my impressions of the direct comparison between the K330 and PA70G. I had the opportunity to test two models for more than 24 hours put in exactly the same conditions (distance, screen, video source).

First: LG PA70G who owned briefly had a serious manufacturing defect with focus. About 40 to 50% of the screen was a decent focus, the other half of the screen had a terrible one. Achieving a satisfactory focus was not possible because the choice was simple - or half screen of focus or blurry full screen I do not know whether the removal of this problem is easy or not, but it certainly should not expect a normal user to perform this repair at home, especially when a product claims to be high quality.

Below classify personal observations of the comparison between the LG PA70G and ACER K330:

Brightness:

No difference in brightness visible with the naked eye between the two brand new PA70G and K330.
Perhaps PA70G is ten percent brighter, but it can not be detected under normal use.

Contrast:

PA70G - 15 000:1 ??? dynamic contrast (FULL ON/OFF) ???
K330 - 4000:1 dynamic contrast (FULL ON/OFF)

I can not believe that a company like LG may declare such value for contrast ratio that even with the naked eye does not seem so. Direct comparison between my PA70G and K330 showed me something I did not expect: ACER K330 is about 2-3 times better static contrast. Black level of the K330 is more than two times lower than that of PA70G, DCR (Dynamic Contrast) also works for K330 (on Video Mode) and was able to further increase the contrast without too much loss of brightness in lighter areas of the picture. Personally, I think PA70G can achieve contrast 15 000:1 if FULL OFF means removing the power cord

Compared with monitor (contrast 1000:1 static, 50000:1 dynamic)
ACER K330 is around 1000:1 static contrast, but PA70G is no more than 400-500:1.

Focus:

ACER K330 really needs 10 minutes to warm up the lens, but then the image is perfectly focused and clear on the screen.
LG PA70G after lens repair is unlikely to perform better.

Some users claim that the problem with LG's focus is not noticeable when watching movies is just ridiculous. I notice it with ease.

Colors:

It is time to say that I am a professional programmer and web designer and I have a pretty good color vision and an eye for detail.
I read a review of ACER K330 in a German magazine, and there was written that the colors are extremely saturated. I agree with this statement and use the settings SATURATION -20%.
Colors of PA70G are more saturated or ultra-saturated, which means SATURATION -30% / -40%
ACER K330 after adjusting the saturation is very natural and accurate colors, it is also factory calibrated.
PA70G having trouble recreating skin tones, green tint in yellow (which is noticeable even on folders in windows explorer), over-saturated and gaudy colors.

With proper settings both projectors do well, but out of the box Acer K330 has better performance.

Post Processing:

Personally, I could not feel the magic of the vaunted XD Engine.
PA70G has more picture settings, but most of them rather like controls combined gamma/contrast/brightness.
For example, Black Level does nothing but obscure the already dark part of the picture
Dynamic Contrast does not work in 1280x800/60Hz, and even if it worked I do not think that would help a lot in this weak static contrast.
In general, I think a good videocard with enabled video enhacements would do significantly more work than XD Engine. I use Media Player Home Cinema with shaders enabled and the result is very satisfactory.

K330 has a smaller range of settings, but the default modes are very appropriate and well balanced as video mode adds much better dynamic contrast and sharpening algorithm to the image.

Both projectors are not suitable for small text and are based on the same algorithm/chipset/DLP for scaling/control of Texas Instruments, so that differences in this respect are quite small.

My opinion is that LG have much to learn before they catch up with companies like Acer/Optoma/ViewSonic in projectors field. When I returned PA70G in store for replacement with a new Acer seller told
me: nobody can produce ovens, TVs, washing machines and projectors simultaneously

I have a few observations and pictures to share, but dropped them in another short post.
I hope this post is helpful to someone.

Hello Pawel,

If I'm not mistaken HX300t DMD has square pixels while PA70G DMD has a diamond-shape pixels, ie the light path is completely different.
The so-called "Aperture Cover" is part of the "Light Absorber", which is described below.
"Light Аbsorber" in PA70G located on the right side of the optics in the front view.
You really painted a beautiful drawing, but maybe easier to find the explanation for this rotated "aperture cover" in the following quote:

System in DMD pixels does not matter because it does not affect in any way how the lens works, is only significant for the way in which colored light will be directed to the DMD but the DMD array is the same as the standard dimensional DMD. Aperture only changes the soil Focus beam passing through the lens. Tomorrow will do sketches and descriptions of how to be properly done in PA70G optics and how it works is flawed everybody understanding what it was but I do not know yet that will put the post because I have to fix the battery charging system on my laptop battery damaged motherboard and the new battery works but does not work so the mains for some two hours my laptop dies . Gums got to me, I have to chip steroujacy charging only improve the soldering because the relaxation one pin motherboard is not soldered.To understand what it is you need to understand how aperture beam of light passes through the lens I will try to explain.LG responded to my inquiry on the present moment, unfortunately, the producer of Korea did not give no answer at this lens will wait :)As for the friend who has a problem with inactive menu functions it is not so with every resolution I noticed all four are active with plugging the DVB-T decoder is disabled RealCinema example in the 720P and 1080P is active but only in 1080i so I think that is the something is inactive depends on the source signal usually think when it is properly recognized by the PnP equipment

Vertical image does not pass through the center of the lens but it is from the middle upwards DMD displays the image upside down before passing through the lens turns to the correct position on the inside of the image enters the lens in the lower half of the lens and the lens comes out of the upper half of the above.  if it was a projector screen at a central location rather than at the height of the lower edge of the screen that is passing by through the center of the lens. Vertical image leans forward so the projector is at the bottom and the bottom edge of the image is perpendicular to the top edge of the screen and the image is under considerable angle if the depth of field was linear and simple image would be blurred towards the top so you can run in the bottom of the aperture of the lens Focus to tilt the soil. This is because the lens is uninterrupted small soil or focusing range is tiles and iris expands the range of soil and sharpening, too, is expanding resulting in a uniform vertical sharpening. horizontally from right to left, the projector is in the center of the screen so it does not require correction because it is deep in the middle of the lens aperture mistakenly lined the left which resulted in what can be seen. Someone will say okay, why do not all equal vertical sharpening is not only diagonally. Therefore, as I wrote the above picture is vertically hinged to the front lens is not flat but convex complicated because the depth of field. Tomorrow is a draw

Thanks for that link, that's a very detailed and lucid article. Just to be clear though, I think speaking in terms of square versus diamond pixels is misleading because the diamond pixels are square too, i.e. they both have 1:1 ratios. It would be more accurate to speak in terms of horizontal versus diagonal arrangements. His explanation of the resampling of a horizontal grid for display on a diagonal one and the related Nyquist frequency mismatch is very clear, but is only part of the explanation for what we see. Even if you designed a complete end-to-end display system geared towards a diagonal lattice, including appropriate fonts, and there was absolutely no resampling involved, you'd still end up with funny looking small text because a very large percentage of character features are horizontal and vertical. A one pixel thin lower case L even if pixel mapped and no sampling errors were involved would not be a straight vertical line but a zigzagging line, otherwise it would appear thinner than diagonal lines. So for very small text display of Latin fonts a horizontal lattice is preferable. For video and moving pictures I think it work just fine and dandy.

Has anyone tried fixing their uneven focus yet? I am looking at the pictures Pawel posted, and comparing them to the ones posted in that Qumi tutorial. In the Qumi tutorial the fix seemed trivial (the two screws you need to loosen are easily accessible). However in Pawels pictures it looks like a slightly different lens?

Again, I think all of the 'this projector performs poorly wahh' comment are silly. OF COURSE youre going to complain when half the picture is out of focus. Save those negative comments for AFTER this huge defect is fixed, THEN judge (and yes, I KNOW lg should be the ones fixing this, not us, but if we can get a simple straight forward tutorial, who cares?).

If someone wants to try to correct the image of the screws, my suggestion is to unscrew the two screws on the left and plant a gap in the two so that the lens was tilted to the right then it theoretically correct operation of the aperture. but I will not tell if you deflect because it would have to do experimentally. the easiest way to improvement.


But it does not eliminate the problem of waiting for wiadomsci far from the factory in Korea and LG will be repaired and consideration to my suggestions.
Edited by Pawel Dubiel - 12/7/12 at 2:51pm

Thanks for the picture. In the QUMI tutorial, it looked like he was able to access the top two screws without having to remove the lens...

http://www.avsforum.com/t/1304775/vivitek-qumi-led-1280x800/1800#post_21450953

In your picture it looks like you disconnected the lens? Is it possible to access the two top screws without taking apart the whole lens? I know you claim the lens needs to be rotated, but The ONLY problem I really see with this projector is the uneven focus, and according to the QUMI tutorial that can be fixed without rotating the lens (just need to play with the screws).

And as for a shim, I am thinking of using a thin plastic washer (Cut in C shape so I can slip it around the screw), think that will work?

I own both projectors and while I agree that the LG can be considered defective due to its focus issue, I still find it to be better than the K330. I am no videophile, and I am just going by what I see on my wall. The K330 is also way louder and drove me crazy with its fan. This is my conclusion after spending several months with both PJs.

Yes you are right, the type of DMD chip does not change the principle of operation of the optical system, but significantly altered the path of light. So the type of DMD chip directly affects the position of the commented "Aperture Cover" or "Aperture Stop".
According to Texas Instruments "Shaped Aperture Stop" is a very effective way to improve the contrast ratio and not in any way affect the other properties of the optical system. Following quote from TI patent relating to this item:

High contrast ratio projection (Texas Instruments patent)

source: http://www.google.fm/patents?id=EjENAAAAEBAJ&printsec=abstract&zoom=4#v=onepage&q&f=false

Pawel, I have two questions for you:

Why do you think LG engineers are complete idiots? Because I think the problem with the production is quite different from the serious problem in the design.

and

Why Acer K330 has good focus, since there aperture stop on the exact same position?

You can see this clearly in the last photo in this post: http://www.avsforum.com/t/1344147/acer-k330-led-1280x800/480#post_21398074

In relation Patent contrastu Texas instruments is fine and so is the aperture to limit false reflections of light reflected from the DMD is not perpendicular to the axis of the lens. Everything I agree but you have to set it to not deform the lens Depth of Field K330 has a different build and it seems that is not the prism was used in the incident light at a right angle to the DMD so, and he has a different construction of the lens and aperture there most probably will not sharpening and affects only locks the false light. In Focus PA70G Additionally the flap on the left side of the lens is still something inside with the serrated edge of a rectangular rounded and not suspect to the iris is to increase the contrast, examine the teeth is all you need one lens PA70G to strip for parts and is already the problem is that such a gain. LG Poland sent a notice to the factory in Korea LG description of the problem with focus and waiting for an answer Korea.

I do not think who and where he is wise or stupid I just got the projector displays an image that does not like it should and no matter who collapsed something important is it that this lens has some problems and especially the projector

I had HX300G was also was also LED DLP and also was LG and did not have such a defect, and sharpened on the screen up to 200 "and the scope of the Focus does not stop at 100" was less than PA70G and everything in it was located and everything needed a prism teeth in accommodate the



you want further proof that the aperture is mounted wrong, please e very zwróćc attention to the exit sign in the bottom right corner of the main menu display is not only darker than white Subtitling left! This proves that the aperture limits the amount of light in the wrong place and why the right of the screen when the aperture is on the left and so the image on the DMD is odwrucony upside down and left to right. You do not believe I've done the test Galaxy S2 via the keyboard choose * # 0 * and reboots test mode you choose SENSOR light sensor and then it acts as a Galaxy S2 Luxometer.and surprise surprise in the test about 1 meter away from the screen in the lower left corner is the result of 385 lux in the bottom right corner is 330 lux is testifies to the iris darkens the active field of the matrix and not the inactive areas. Does anyone else thinks of it has to be? because no one will convince me that this lens is properly constructed.For testing, I used a blank screen in blue color.
