LG PA70G LED 1280x800 700 Lumens. - Page 71

post #2101 of 2305
Well the problem is my room IS whisper silent (I use it for listening to music as well as movies), so the fans really stand out. I am seriously considering trying to mount 4x 120mm fanse (two intake 2 exhaust) on the sides of the case.

But FIRST I want to try and up the focus a tad. After getting my projector back from LG (for the UNEVEN focus issue), I now have the issue where the wheel wont focus beyond a certain point. It still looks 'ok' but I know it would look sharper if it could just focus a tad more. Does anyone have detailed instructions for how to adjust the wheel so it has more range of focus? It has been kinda mentioned a few times before, but not in much detail.

If i remember correct you would have to dremel down the screw holders of the lens to get beyond your current focus Maximum.
Since the lens would be more near to the mirror there is more room for the wheel then.

In my case i had to loosen the screws a bit and reposition the lens for nearly perfect even focus. But that didnt expand it ofc. I can focus my Image up to about 120" from beginning. But only after the focusfix and using the inf file for native 16:9 i got a sharp Image at all.

Look for "(edit:) DaGamePimp" posts he was the one who did the most detailed explanations about the focus expand here.

(sorry i corrected my assumption^^)

Actually...

I was the one that made the simple focus wheel adjustment and explained it (regarding the lack of focus range for larger screens due to the filled section on the focus wheel teeth not being placed optimal by LG).

The other suggestions made in this thread are more involved and will likely void the warranty, if one is careful my fix can be done with no trace.

I explained it in this thread a couple times and as I said each time it will make sense once you have the cover off and see it for yourself.

Best of luck,
Jason

I have Windows 8 on my PC. The .inf files that are released here are not usable on Windows 8.
pls help

@DaGamePimp

Well I just cracked open mine, and I DID see the little block in the teeth, which DOES indeed prevent the wheel from spinning in one direction. However, that seems to be the direction I don't care about (rotating the wheel that way would only allow me to make my picture MORE blurry)! What actually seems to be blocking the focus wheel is a little screw surrounded by a white plastic tube, sitting in a groove/channel on the top of the lens itself. It will only rotate so far, then it hits that screw.

I looked back through the thread for your 'tutorial' but I couldn't find it. What am I missing here? I know multiple people have said they were able to get some improvement by simply repositioning the teeth on the focus wheel, and I assume it was to fix large screen focus issues, not tiny up close focus issues (my screen is 128" btw).

I hope this isn't as good as the focus is going to get... frown.gif

*And while digging through the last 60 pages I came across a post by thomask (page 61) who posted some nice screens. So it seems like 1280x720 @120hz is the optimal resolution to be running with this projector? But he did not explain how he created his inf, or how you install it.

http://www.avsforum.com/t/1405666/lg-pa70g-led-1280x800-700-lumens/1920

Also on on page 41 Rugrash posted a inf as well, but again, I am a little fuzzy on what to do with it.

http://www.avsforum.com/t/1405666/lg-pa70g-led-1280x800-700-lumens/1200

I am running Windows 7 with a ATI Radeon HD 6900.

Well if you are at max range already (for longer throw / larger screen) then obviously adjusting the focus wheel will not improve things (just make sure what you are seeing is accurate, I had it backwards upon my initial inspection regarding the lens direction wink.gif).

Beyond that... you are projecting an image that the PA70G is not designed to do (up to 100"), so you are outside of proper operation parameters, and as such you just might have to accept the cons that go along with it.

I never wrote a full tutorial but I explained it as simply as possible a couple times in this thread and as you said you do see what I am talking about once inside (so now it makes sense). wink.gif

Honestly with all of your personal cons it sounds like this simply is a bad choice for you and you can likely find a better fit.

Best of luck,
Jason

I never meant to make it sound like it's 'blurry' currently, it just stops focusing after a certain point, which seems strange. Before I sent it in for repairs (for uneven focus) I was able to get clear focus on my 128" screen (on one corner at least). I still think something is wrong, but short of removing that one screw I'm not sure what to do.

Maybe the custom monitor inf will help improve the sharpness a tad. Can anyone please explain how to use those custom inf files? I have one that rugrash posted awhile back, and it looks to be setup for 1280x720 120hz, which is (according to a few people in this thread) the best quality? I'm just not sure what to do with the inf file itself...
post #2108 of 2305
@avsforumun all Infos, guides and tutorials are provided within this thread and it took me 2 min to find what you couldnt find or not tried to. Page 63..

Anyway here are the posts where i explain the EDID override and the following instructions how to make the custom 1280x720p@120hz res work.

I take all back my PA70G is good now. No more sharpness issues anymore its only about the correct setup which is not that easy but its worth it. Im very happy now. The picture is crystal clear and fast action in movies is perfect and not eyestraining or something. 24hz/24p didnt work anyway so 120hz is way better for me.

It was a bit tricky but here is what ive done:

1. overinstall the HDMI inf file for 1280x720p@120hz as described in this thread.
2. restart pc, plug in plug out projector.
3. create custom resolution settings in nvidia advanced settings. right click desktop - resolution - advanced - select intel graphics control panel - propertys - advanced mode - create custom resolution (use here 1280x720p@120hz and add it)
4. now close all windows or even unplug / restart if needed. then select 1280x720p@120hz in the nvidia system control - voila!

Have fun and i hope this helps someone. If you have a question feel free to ask. Im one happy PA70G user now smile.gif

Also, what DLP 3D glasses do you guys use with the PA70G? Looks like I'll have to import some, DLP glasses seems to be very rare in South-Africa.

When you got the file go to your device manager and overinstall the standard monitor driver which stands for the PA70G when it is connected. Select the inf file by selecting the correct driver manually.
I only have Win 7 64bit dont know if it works with Win 8...

Then restart the Notebook / PC / HTPC and follow my previous instructions. Sorry that i cant upload the file here but it is called "PLED-W500 HDMI 1280x720 120Hz native".

I couldnt get 3d to work with this EDID override it still lets me only use 1024x768@120hz for 3d but its not really worth it anyway since its too dark to enjoy with this projector.
If you still want try you need DLP glasses with white flash sensors and 120hz support (which they all should). Its the right one when it has a white but black sensor in the glasses.
Then you need stereoscopic player and set it to software pageflipping mode in options and dlp link glasses as the control codec for glasses. The effect is awesome if it would be alot brighter but as it is its not very recommend for longer sessions cause its soo dark. The glasses take about 70% brightness away which doesnt let much left to even see anything on about 100".

And about 128"... I highly doubt it will ever work even with the inf file. My unit can Focus till about 120" which is obviously the Maximum. Currently im projecting on a 110" Screen and got little room till 120" but if i would go past this and set it to infinite there would be a slight blurry effect that cant be compensated.

This little newtech Mainstream projector is not designed nor has it the light output for such big Screens and we can be happy that it works beyond its given speccs of 100" but we shouldnt go too far beyond that.

Even with 110" the lightoutput of the PA70G is so low at day that i have to use blackout cloth to make it work. My old SP-F10M was feeling wise 50% more bright compared on the same screen let away blackout cloth.

Gah well I finally figured out that the .inf is considered a driver, and the 'update driver' button from device manager is how it is applied. However, the whole point of this was to get a sharper nondistorted picture for 3d, and come to find out you cant do 3d when in 1280x720 mode... Gah! And now every time I try and go back to 1024x768 120hz, it will stay in that mode for about 15 seconds, then flips back to 1280x720 frown.gif so I cant even get my old distorted 3d to work.

Does anyone have a working inf that will allow for non stretched/distorted 120hz 3d mode? Or at least the original inf so I can get things back to the way they were (the 'roll back driver' button is now greyed out after reboot).

What version of Windows do you have? As is customary, when you change resolutions, Windows will ask if you want to keep the new resolution or else it will revert back in about 15 seconds. Are you not confirming the change?
post #2111 of 2305
Win7 64 bit w/ ATI Radeon HD 6900. The only place I have the option to change to 1024x768 120hz is in the ATI catalyst control center. It never gave me a 'do you accept this new resolution' pop up. Before switching to the new inf the change to 1024x768 would stick just fine. Now (after applying the new inf) the change reverts back after about 15 seconds...

I really dont even want to go back to 1024x768, ideally I would like to get 1280x720 working with 3d.. I thought for sure somebody in this thread said they got it working... I mean wasnt the whole point of these custom infs to get 3D working in a non distorted resolution?

*and just incase it matters - I am using a hdmi cable (straight from my pc to the projector).
post #2112 of 2305
I ordered the pa70 now after the pb60 had a very annoying focus bug and the fact the focus on it wasnt ajustable anymore since it was screwed on tripod mad.gif

Still hoping i'll get one of the January 2013 cuz the reading here made sure that they got better in that time.
post #2113 of 2305
Posted this on the PA75G thread. . . figured I would add it here. . . as I know some of you will have the answers to my chromatic distortion question. Thanks.
Quote:
Just received our PA75U from newegg yesterday afternoon.

Will most likely do a "review" after we've had a little more time with it.

Questions to other owners, and will post same question on PA70G thread. . . (double posted)
I'm seeing a good amount of chromatic distortion/aberration when using a grid pattern to focus this thing. Blue on top of the line with green below (each about one pixel). Don't notice it far away or when watching video, at least I don't think so. Are others seeing this same thing because of the horizontal pixels?

current findings
Our focus stops just after it is in focus (@ ~90"), not a lot of room afterwards. Might have to do the adjustment people speak of later. Have not noticed any focus issues across the screen, though.

The TV tuner seems to be pretty good even with the external antenna they supplied.
Fan turns off immediately after turning the projector off — currently using max eco which is very very quiet compared to our BenQ W1070.
Haven't used the WiFi a lot, not sure about it yet — will try to get the wireless options going later.
Many settings are absent using HDMI.
Plays MKV with DTS audio no problem via usb, struggles with large remux MKV bluray and plays all available audio tracks, apparently — tested my Hancock and was getting the discussion track as well as the regular.
However, with all these nice inbuilt features they forgot to give us a decent audio out — only the headphone jack which is two channel only! If I had a decent audio out I would be running this without any cables to it! Bummer!
Notice much less image noise with this thing over the BenQ W1070.

Finally, I swear the pixels on this are smaller than the Dell M110 — don't have it around now to compare the two. Thus, the image on this does appear very sharp.



Maybe we should merge this thread (the PA75G thread) with the PA70G thread???

Hope some of you PA70G owners are still following this thread. . .

After playing with our new PA75U a little I've found a couple issue.

1. focus ring stops right about when it comes in focus but may need a little more adjustment for perfect focus — considering doing the fix, haven't found specific directions yet.
2. focus is off from top to bottom. Can't have both optimally focused — it's not horrid but noticeable with text.
3. chromatic aberration/distortion (CA) is obvious when using a grid pattern to focus if the lines are small — blue on one side, green on the other.

The question for you all is, is this a keeper (and attempt focus fix) or try for another one? Not sure if the focus ring issue is consistent in these models or if some are OK with plenty of room for adjustment even at 100" screen size.

Also, not sure what others are seeing with CA. . . if what we are getting is common then no point in trying again.

Still testing, not sure if focus is going out during use or not, it might be — anyone see this issue on these models? I've heard about it on other brands but not the LG LED projectors.

However, the image can look very good when sending a full blu-ray — re-watched part of "Avengers" and it looked pretty darn good at ~100" as did "Hancock."

thx

Well, to check focus on the LG, do you have screen? Make sure you are straight back from screen, and about center height of screen with PJ. If one side of screen is closer to PJ , just make sure everything is lined up right. If you don't get pretty good focus top to bottom, left to right, with PJ and screen perfectly aligned, you might want to replace it. If PJ is tilted, or placed too low or high, or 1 foot to the left or right of center of screen, the stretching makes for slight unfocus in area closer to PJ.

10 feet back from screen is 100 inch screen, 12 feet back is 120 inch screen. Probably the sweet spot is about 100 inches, does the focus wheel have someplay in it at 100 inch screen . Instructions have been given the last week or so for adjusting the focus wheel opening up the case.

Now if you get good focus when your LG is aligned perfectly, then you shouldn't be upset if in some room setups, if you are not aligned perfectly, and it's a little blurry, your PJ is working perfect, but you might have to readjust placement a little. Maybe tripod? or accept slight unfocus in one corner just for the placement in that room. Since you just got it, you are testing to make sure you got good unit, before the exchange policy runs out. So experiment and keep asking questions.

Some of us did have to do exchange on the LG, so, think about whether you need to do it or not, and maybe others can give their perspective on it.

Using the same screen right now that our BenQ W1070 uses. Maybe this projector has a slight upward angle? I'll check that tonight.

Our LG is currently ~9' from screen and has very little play in the focus ring. will have to find out how to take this thing apart.

Certainly, if it isn't aligned it will be out of focus wink.gif

thanks

Oh, do you notice any chromatic issues? I've seen others talking about it here but nothing too specific or close up pics, but haven't read every thread yet.

I have the PA75U.
1. I have a 100 inch screen and I have just enough play on the focus wheel for it to go out of focus, then I dial it back just a bit to get it focused. I don't have problems with it going out of focus after it is in use. I haven't adjusted focus in quite while since I got it all mounted on ceiling, aligned, etc.
2. My focus is fine is uniform, but I did have to make 2 exchanges at Best Buy because the first 2 had corner focus issues as detailed with the PA70G in this thread. (1 corner would be out of focus, adjust wheel to focus that corner and the opposite corner would go out of focus)
3. I'd have to take a closer look for CA but I haven't noticed any issues as of yet.
post #2119 of 2305
Got the top off and the lens shift stops because of the plastic stopper screwed into the lens, not the focus ring teeth. Don't see how I can possible adjust that — didn't really see this part being altered in the videos. However, I think part of the issue might be that the lens is at a slight angle. So, I put a peace of cardboard under the back and that seems to help however, it needs to go to the maximum the focus will go to, and possibly more but don't see how I can accomplish that.
post #2120 of 2305
Also, how am I supposed to do a color adjustment on this thing when I don't get the color management option when using HDMi?

Jason (dagamepimp) stated that he was able to get this thing pretty spot one. . . I don't see how. Could someone clarify this, please?
post #2121 of 2305
did you go to one of the expert picture settings ?? there are 2 of them. I have both of my set up one is for movies and the expert 2 is for sports and general HD. I was able to use the Digital Video Essentials: HD Basics blu ray to set the colors with the color filters. blue was a little low and red was a bit high. after adjusting in the expert settings I got it dialed in pretty good for blu ray movies and HD programs and sports. for the best pic try one of the expert modes good luck.

I'm using expert1 & expert2. Did the wizard and went form there. However, setting expert1 & expert2 identical and they are different?!?!?! One's lighter than the other.

Furthermore, the "color management" is NOT available in the expert1/2 modes. It only has "white balance" with red, green, blue they don't seem to do anything — think that's just for adjusting the white, not colors.

FYI, this is via HDMI. The only color settings I have in expert1/2 is "color" (total saturation of all color) and "tint" (shifts red-green) — "color management" is NOT available in any of the "picture modes" when using HDMI — settings are actually pretty bare.

So, thebigdaddye, do you have access to the "color management" in expert1 when using HDMI?

Thanks for the reply!
post #2123 of 2305
I guess I thought the adjustments in expert picture mode for cyan, magenta ect.. color adjustments along with the blue, red, yellow ect.. tint, contrast and color adjustments was the color management and yes i'm using hdmi.

That sounds like the "color management" — red, green, blu, cyan, magenta, yellow each with saturation, hue, etc. . .

I don't get those settings when using HDMI on the PA75U?!?!?!!? mad.gif
post #2125 of 2305
what do you have hooked up to yours ?/ directv ps3 or pc? if it's pc it won't let you try unplugging the hdmi from the projector and plugging it back in if you have it connected to your pc and it might let you adjust them then. if your hooked up to directv or ps3 then the color management should be available. hope this helps oh and I have the pa70 version

I posted on the other thread before your reply here, I think. Just wanted to ask those with the 75U if they were seeing the same thing.

I am using a PC and I did your test. Yes, if I unhook the HDMI I get the multitude of settings. Now to find out if making those changes will actually be applied to the HDMI input when I hook up the PC. Really don't understand why they don't just leave it working with HDMI, their TV we had allowed for color management changes. . . oh well!

Thanks you very much for the info!!!
post #2127 of 2305
no problem I saw it.
post #2128 of 2305
The settings that are available to adjust can vary when sending YCbCr or RGB.

Jason
post #2129 of 2305
To use the colour management from a PC you would probably need to set the 'pixel format' in your graphics card driver to YCrCb instead of RGB.
