After lots of reading, i have managed to put the following together, please note that all this information has been taken from other posts on this thread and all credits go to the original poster.
I have not yet tested any of these so all suggestions, verification and constructive criticism is welcome Tips and tweaks for the LG PA70G
- Draft version 1

1. Do not use keystone correction if its not necessary because keystone correction recalculate pixels so you loose image quality
2. Set 1280x800 resolution on your PC, if you set for example 1920x1080, then projector will recalculate it to 1280x800 anyway, so you loose image quality too.
3. "just scan" option is disabled
*Right click on desktop and select "screen resolutions" from the menu.
*Click on the "Advanced Options" text link.
*Click on the "List All Modes" button on the popup window.
*If your current selection is 60 Hertz, select from the list the same resolution but at 59 Hertz.
*Apply/save the 59 Hertz resolution setting.
*The "just scan" option should now be enabled in the PA70G menu (along with all the other options that may have been disabled).
4. run the Picture Wizard II in the Expert menu, it will result in a big improvement over any stock picture modes. Make sure to dial the brightness back afterwards, it always switches to Max brightness
5. For movie modes turn off dynamic contrast (it ruins the colors)
6. Fix Focus (Might Break Guarantee)

* Tools: one long nose philips driver with large enough handle to open the case, and to adjust screws inside the projector: one flash light to look into the projector; a knife or driver to pill off a black tape (I will explain it later)
* Turn over the projector. On the bottom of the projector, there are 4 screws. Unscrew them, and put them on the side.
* Turn it over while holding the case nice and tight. Set it up on a table. The case is divided into "the cover" and "the bottom cover".
* Take the "top cover" of the case. Carefully and slowly. You will notice that the "bottom cover" holds all projector parts.
* Connect the cables to the projector with a video source. I just connected it to my computer.
* Turn the projector on. I played a video file with the media player visible on the projector screen, so that I can see the focus on the left and right corners .
* Adjust the dial on the left side of the projector and make one (either left or right) corner sharp and focused. At this point, you will wish both side are THAT focused.
* There are three screws (there might be more, but I could only see three). I know Honzik1 stated that he played with two screws. I guess you can fix the focus issue by manipulating just two screws. Anyway, one screw is located under the black tape. One is located (if you look at the lens) on the left side of the lens, and the last one is located on the right side of the lens. They are located around the lens at almost triangular locations. The ones on the sides are hard to reach. This is why you need a long philips driver with large handle. 2 screws on the sides are a bit difficult to reach if you don't have a long driver.
* Carefully, take off the black tape with a knife (or something sharp). Your fingers wont work. I know, I tried.
* Slightly unscrew top screw (the one located under the black tape that you just removed) slightly by turning it counter clockwise.
* Slightly unscrew screws on both side.
* Don't unscrew too much, just a little at a time. Like Honzik1 suggested, half or 1 full circle should be enough.
* You will notice that the sharpness and focus changes as you unscrew them.
* Screw, and unscrew one screw at a time until you achieve the most sharpness and focus. There was no magic trick. It took me about 5 minutes to find the best focus.
* I actually stopped adjusting screws when I got a focus that I could read AVSforum posts and small texts on both side of the screen, and see video play sharp and focused.
* Put the black tape back on.
* Turn the projector over and screw the 4 screws to the bottom of the projector.
* Check the speakers if they do not block the opening. And check the focus wheel if it do not block it also.3D General
1. Change your resolution to 1024x768 @ 120Hz and enable 3D on your projector
2. Install one of the attached monitor drivers if necessary3D Movies
1. Install and configure Windows 7/8 Codecs with LAV decoder (http://www.windows7codecs.com
) ( LAV decoder is included in the pack)
LAV decoder configured:
* decode Xvid/Divx/Mp4v/Avi/Mkv/H.264/AVC
* use hardware decoder DXVA2 Copy Back method (Radeon) or other (it's GPU depending)
) - Player works great with movies
2. Steroscopic Player ( www.3dtv.at
* settings -> Advanced Settings -> Troubleshooting -> Hardware decoding (ticket or unticked ?)
* playback option -> Glass control setting -> none (Fixes white line issue?)
* use LAV decoder for Mpeg4/AVC/MVC videos
* viewing method by Software page flipping3D Games
) - Tested and works great on most games:
Ensure sure you have an ATI 5000 series or higher graphics card (would someone like to give feedback on Nvidia).
Disabling the power 3d function on the in game tridef menu (Key pad 0) improves the 3d quality drastically on certain games.Monitor Drivers
