LG PA70G LED 1280x800 700 Lumens. - Page 45

I am still as confused as ever! I have tried my best to follow this thread and English is my primary language.

With the AMD Radeon series of cards CCC allows forced refresh rates. When I used the forced 120hz it forced the output to 1024x768 and I confirmed the output on the display of the projector (I pressed the info button in the center of the dial).

I don't own DLP Link glasses so I could not test the 3D function.

So what is the consensus on the projector and 3D?
1. Are the owners who have video cards capable of displaying 1024x768 @120hz getting that confirmed on the projector? What about 720p @ 120, is it confirmed and how was that confirmation made?

2. Based on the user's manual there are programs that LG recommends be used to send the frame alternating images to the projector. How well did these programs work in sending 3D images to the projector? Were other programs tried?

3. For 3D the manual recommends a 40inch image and a 3m distance with the power savings set to minimum i.e. the brightest and noisiest projector setting. Has anyone reported on the results of testing the projector according to LG's recommendation? How enjoyable was watching 3D movies?

4. Finally, I wanted to buy some 3D DLP Link Ready glasses but none that I have found seem acceptable: I prefer lightweight goggles with AAA batteries instead of lightweight glasses. Glasses don't fully isolate the eyes. Further glasses have smaller batteries with shorter viewing times. Has anyone made lightweight DLP link goggles yet?

Cheers,

And Welcome to the start of another exciting solar cycle!

Yes I also have a WinXP 32 rig with a Radeon 5750 but that's in my HT and while I can try it with wireless HDMI I am not going to bother as that is not the solution that I am after, I want this to work with my gaming pc.

Plus I hear that only the 6000 & 7000 series Radeon cards do 3D gaming well (I am not all that interested in 3D media playback).

Not ready to deal with LG just yet and not even sure they'll be much help (if any).



I verfied the inf, the display name changed so it was no longer on the stock windows monitor.inf (checked in the Device Manager).

Once again thank you for all the input, you are covering all the bases, it's just that I have already rounded them.

Jason

Lol, I went to uninstall a monitor driver I was using an inadvertently uninstalled the monitor. Problem was I was eating and I suck at multitasking :P

So anyways, a quick system restore and I'm back. I tried tatinkos EDID, it worked and gave me 120Hz but there was something that was off, the text was slightly garbled and it just didn't seem right.

I double checked that I uploaded my HDMI EDID with the 1280x720@120Hz, but it's not installing for me, I think I need to removed the extension flag from the inf file. My thought is that there's a data desciption in the extension block that is taking precedent and thus blocking the custom resolution. I'll try to remove the flag and repost.

But anyways, like Obscuro stated isn't there a 1024x728@120Hz resolution option written in the LGs EDID to begin with, that you can use to enable 3D for the time being? Either on HDMI or VGA?

Yes, I can enable 1024x768, 1280x720p and 1280x768 @ 120 Hz by default (without a custom monitor.inf) yet it still does not work for 3D via VGA or HDMI.

Jason

Ok I modified my EDID by removing the extension flag, this may cause there to be no audio over the built in speakers, I'm not real sure. I also added a frame sequential format data check in it. I would have changed the color profile and will do so later after I make sure I have a correct profile to use. PLED-W500 HDMI 1280x720 120Hz native.zip 1k .zip file

So Jason, you are selecting Direct3D Stereo and using the TriDef game launcher correct?

Which game are you trying?

Are you getting a double image on the screen?

Is 3D activating, and it's just the glasses are not?

If I select any of the standard display type options for Direct3D TriDef disables 3D and says there is no 3D capable display.

I have tried many games from the TriDef game launcher (including Trine 2) and checked the options to no avail, it simply will not see the LG as being 3D capable.

3D does not 'activate' at all unless I pick the Samsung 3D ready DLP options but I think you are correct when you stated before that it is sending checkerboard (even though it looks different than iZ3D checkerboard output).

Jason

Yah, Checkerboard enables but it doesn't demux it just the two images overlapped as one. You had me excited when you first posted that, I thought it was actually working. Unfortunately, non of the projectors support that as a format, although DLP TVs do as well as some LCD TVs.

Do you have another display connected, it may be interfering with the Tridef seeing the LG.

Maybe reinstall TriDef and make sure it has adminstrative priveliges while installing?

When I set my desktop to 1024x768@120Hz using my factory default EDID, as soon as I open the TriDef control panel, the selection options all appear in 3D (such as the video controller icon)

If and when you get it working. The games must be Full Screen to work and set in game to the appropriate refresh and resolution.

If you are getting no error warnings and 3D seems enabled isn't working, try enabling and disabling the 3D option while the game is running using the hot keys (alt+shift+-) or alt tabbing out of the game, then back into it. Sometimes this will jumpstart it.

I am using Win7/64bit and nVidia GeForce GTX 460 with the modified monitor driver from Tantiniko set at 1280 x 720 120hz. This throws off 1-1 pixel mapping and I get some part of the screen cut off on all sides. I cannot fix this with overscan or other options in nVidia setup menu. However, I am able to set the PJ into 3D mode which tells me to put on the 3D glasses. I have FX-30 glasses which Tantiniko referred to in his post. When I put them on I can see the lenses of the glasses changing color looking at the screen but when I play them on Stereoscopic Player 1.9.4, no 3D images.

So it definitely seems we have a pattern here... nobody can get 3D working properly on the PA70G (the claims made from a single person do not convince me that it works).

It may be time for all PA70G owners to call LG and register this 3D issue even though it's likely we may not see a proper fix. I'm sorry to say that LG has a history of one step forward two steps back when it comes to firmware updates, if this unit is even capable at an end-user level..?

I have spent far too much time trying to get this to work and just about ready to give up on it. If anyone else in the USA has actually obtained proper 3D from the PA70G please post, there simply may be variables on the euro models that we are not aware of.

Big thanks to Rugrash for trying to help the rest of us even though he does not have the PA70G, your time and effort have been very much appreciated.

Jason

Try uninstalling the EDID override you did and make custom resolution profiles in the Nvidia control panel. Use CVT reduced blank if you are using a HDMI connection. CVT if Analog.

Edit: try both, use whichever responds the smoothest and fastest when you click test.

I believe that tatinko has it working, although maybe not quite as good as he can judging by the EDID he uploaded.

I switched back to my Radeon rig to give 3D VGA gaming a go, but I'm finding it to be problematic compared to my Nvidia card.

It seems that my 7970 does not want to detect my projector that's currently connected with a 20ft VGA cable using a DVI/VGA adapter.

In Catalyst Control Center it tells me that the Display Data Channel is not supported. I try to make custom 120Hz resoltions but it only shows up at 1024x768@120hHz.

Also when I use Monitor Asset Manager, it does not list an active registry for my display.

I just got home, so I've only spent a few minutes on this. I'll investigate farther to see if I can determine the problem I'm experiencing.

I was using a VGA connection and I tried both custom resolution from nVidia and Tantiniko's monitor driver to set the video in 1280 x 720 120hz. Neither has worked. I will email and contact LG regarding this as well.

It turns out there's a problem with my cable, it's either defective or a problem with the length. I suspect it's a problem with the cable, since VGA cables have a greater tolerance for longer runs compared to HDMI.

So I used my shorter cable and my Radeon 7970 easily recognized my projector with it's supported resolutions and timings. I was also able to see it in the registry now using monitor asset manager.

I easily enabled 3D using TriDef and the PLED-W500 default 120Hz resolution of 1024x768. PLED-W500 owners also have the problem of limited factory EDID support for 3D.

So using CRU Utility I created some custom resolutions, rebooted the PC and was able to enable 3D at 1280 x720/800@120Hz.

Unfortunately, AMD Radoen cards, do not have a built in custom resolution option like Nvidia. They do have one actually, but it's very limited.

The part that tells you to put on the 3D glasses, is that a menu from the PA70G or from stereoscopic player?

It's from the PA70G. As I stated before, lenses on the glasses blink when I face the screen and I can detect a change of color in the lenses but no 3D. I am also new to the PJ realm but pretty well apt in computer and electronics as DaGamePimp is. It may be a software problem from my end but I am not sure because I am also novice at setting up 3D in PCs/software.

I am not new to front projection, been doing it for 12 years, just new to the PA70G and LED based projectors.


I wish it were as easy as the cable, I tried 2 brand new 6' VGA cables direct from the pc to the PA70G and no luck even though I can send all the mentioned resolution options at 120hz.

No 3D at all no matter what I have done and I think I have tried just about every possible variable.

Thanks again Rugrash for all your effort.

Jason

Sorry, DaGamePimp, did not know that. Yeah, I have almost given up on this thing.

Thanks to all of you for info and assistance.

Oh no reason to be sorry at all as we are all learning this pj together and even seasoned enthusiasts can come across a bit noobish. I admit I feel really silly that I cannot figure this unit out since I am usually very capable with anything A\V related.

To be honest I am not even sure why I am so hell bent to get it working in 3D since I know the end result will not satisfy on the screens that I currently have (100" & 133"). I also have a 72" perm wall Da-Lite but that's not enough of a difference from my 60" HDtv to justify using the PA70G.

Jason

Did anyone try this Fix for 3d on this thread?

http://www.avsforum.com/t/1446254/lg-pa70g-3d-problem

peace

Butch

The reason I asked is because on the PLED-W500 and my friends Qumi, there was no such prompt.

On mine when I go into the menu and enable 3D, it stays on until I turn it off. There is no prompt to put on my glasses at all.

It's a shame that you're having trouble making it work, I would imagine that as well as it works on my PJ, it'd be much better on the LG.

Yes tried it, no go for me.

Jason

I am ignorant about this, but want to throw it out there, my laptop intel vid card shows the LG PA70G as "Digital Television LG PJTR" does anyone else have that and if so, could it be a communication problem getting 3D to work ? Maybe need a monitor driver ? Sorry noob here trying to help

There you go, that link explains it.

Just be careful about finding a good H5360 EDID/.inf file. I remember trying a few that were messed up with corrupted checksums and timings.

When you find a good one, upload it here for others. You'll need to zip it, since you can't upload an .inf file here.

Also using that EDID, you can use 3D Vision for 3D gaming if you have an Nvidia GPU and 3D Vision emitter to plug in. Just wanted to add that again, I've mentioned it before.
Edited by Rugrash - 1/4/13 at 3:53pm

Mine does not say that.


I tried it with several different .inf files from different 3D ready DLP makes/models and none of them worked but if there is indeed a known good one out there I would certainly try it again.

Jason

Here are the two Acer inf's that I tried...

Acer5360inf.zip 2k .zip file

Jason

Come to think of it, it may have been the simple fact that I hotplugged the shorter VGA cable in, that caused my Pled-W500 to be recognized.

I have noticed that my Radeon card is more problematic recognizing EDIDs than my Nvidia card.

BTW, the way I read inf files is I use monitor asset manager to open it and then create a bin file from it.

Just use the open file icon and browse to the location.

I then use Extron EDID manager to read it, it will only read a bin file.

Here is a new .inf that I have not yet tried...

Acer_H5360.zip 1k .zip file

Jason

Ok the .inf that I just posted (post 1349) works (the first two that I posted did not work on my gpu).

I am now getting 3D video via TriDef (VGA) but I have no audio since it will not allow me to have any other display/output connected and I am using HDMI for audio.

So far I have only tried 1024x768@120Hz, will try the other resolutions soon.

Major thanks out to the AVS'er that discovered this could work and 3rd time is a charm for me once again... 3rd PA70G and 3rd Acer .inf attempt.

Thanks to all those that have contributed and especially Rugrash for his tireless effort to help the rest of us get this working.
