LG PA70G LED 1280x800 700 Lumens. - Page 54

OK, PA70G and PB60G, display a picture at 16:10, but it always can, switch the aspect ratio.
There is only one but if orginal is in 16:9 and you have the 4:3 aspect ratio image is stretched meringue, smile.gif if you have the opportunity away the projector to 3 meters from the wall on which we will display the image, almost 100 ".
Remember with a steel focal projectors and have no ZOOM, image size varies by changing the distance of the projector from the screen.

If you want to know more to download instruction manuals, from LG. unless it is in one of the first posts. smile.gif
There you will find tables screens sizes and distances.

Overriding of the EDID should fix the detection issues?

I'm pretty sure the problem that you are running into has more to do with how each individual game developer implemented resolution detection.

Nvidia stores it's Custum Resolution Profiles in a seperate folder in the registry, and may be part of the problem, but I highly doubt it.

I previouly posted an EDID with several 120Hz profiles, did you try it?

I also previously posted a program that allows a person to edit the EDID in their registry, did you try it?

There used to be programs like refreshlock and refreshforce, but they have not been updated in years. If you use XP, they may work.

Rivatuner used to allow a user to do this, but it also hasn't been updated. I'm pretty sure the feature was dropped when Rivatuner was turned into MSI afterburner.

Yes I'm pretty sure it is also.

Its the fragmentation of these resolution/refresh rate profiles that is causing the detection issue, Nvidia does its's own thing and windows does it own thing, but they all rely on the inf driver file if I'm not mistaken, which means if you have a driver inf file with your required setting all other things should fall into place.

Thanks alot for the previous INF upload, I'm at work now and can't check the file.
I must have tried it, I've been through all the pages in the thread, got my PA70G at around page 20-30,
this thread showing that 120Hz at above 1024x768 was possible is one of the main reasons I got the PA70g, that and it was on SALE smile.gif.

I tried a few, powerstrip being one but not all the setting sync up, powerstrip is missing 2 fields.
a couple others I tried were outdated didn't detect the setting correctly to begin with.

I'll give creating the INF myself a try again, but feel free to do your own it would be appreciated.

And have you tried to use VGA?

I was uing VGA since I got the projector at 1280x768 120Hz for games and 1280x800 60Hz for normal use, but this past weekend I tried out my DVI to HDMI converter and got more picture quality option on the projector and out of curiosity I tried out the 1280x800 120Hz in Nvidia custom resolution panel
The Black level Option in particular seemed to work wonders with the image smile.gif. but Like I posted before 3D is not my thing for now, next month I'll get a couple of 3D glasses and I'll give it a go, but for now It is all about the 120Hz and it seems to go all the way up to 1366x768 120Hz but this is above native resolution horizontally and below it vertically so I'm not sure about the pros and or cons even if it is Dimond Pixels.
post #1595 of 2305
Does the PA70G come with an installation disc that includes monitor drivers(inf files)?

If so post the one for HDMI.

There is no fragmentation of refresh rates and resolution, each Display/GPU output port/connection type (HDMI,DVI, DP, VGA) has it's own registry entry.

This is the way EDID(extended display data information) works, there are only so many bytes available in the data blocks, so anything Nvidia does above and beyond that must have it's own registry entry.

The tool I used was CRU, it puts the display into test mode so that you can edit the current registry EDID. You can use it to freely swap the native resolution profile, untick the extended data block and add/edit custom resolutions as well as edit the standard resolutions. But it does not allow custom downsampling resolutions.

In doing so, the display shows up as generic. To reset back to normal, uninstall the driver and reboot or whatever it says at the website.

I thought powerstrip allowed custom game profiles and could force refresh rates, it doesn't?
post #1596 of 2305
Unfortunately, I haven't found a real good way to edit an EDID.

You can easily overwrite the native resolution of an EDID with Monitor Asset Manager using it's edit feature.

But it only works on earlier HDMI specifications, in some of the later versions you can have multiple native resolutions.

There are several EDID Editors available, the problem that you run into is what they can open and what they can save as.

One might use hex files, another dat files, another bin files, another txt files, etc..

The only one that creates an inf is monifo, but it often does so incorrectly when converting one of the files mentioned.

I don't know anything about file types, perhaps there is another way to convert these files or use them as an override in their native file format.

But as far as I know, windows requires it to be in an .inf format, to be used as an override.

I'm not really happy with the focus of my PA70. Besides the lousy focus wheel I think this blurred image is mainly caused by the bad convergence of my device.
Look at this picture taken from a very short distance. This red and green shift is constant over the whole screen.



Does anybody know, how to fix this? I have already looked through the Service Menu and have not found anything suitable.
post #1598 of 2305
Somebody stated in this forum that the focus problem only present during reading texts but not on watching movies, can you confirm on this?

Well, it is true, some people got unfocused units, especially when the PJ first came out, now , more of us are getting focused units and good focus wheel action. So I can read the text no problems on my unit. Now, I do use bigger fonts , same as I do on my 42 inch hdtv, so I can read everything, no problems. Now some people when the PJ first came out, opened up their unit and adjusted a couple of screws to get good focus. And some people that had units that didn't have uniform focus, said it didn't bother them at all when watching tv or movies or gaming. But with my unit, I can also websurf and do PC stuff no problems.

If you do get an unfocused model, just exchange it.

I'm not sure what WirelessCabel is addressing, so I will leave it to the other guys to address his question. I thought about responding, but didn't feel I had enough info about his setup to say anything useful. So decided not to respond.
But I have excellent focus on my unit, top to bottom, left to right, and my focus wheel play is EXCELLENT. I'm happy. biggrin.gif

You are either not at optimal focus or if you are seeing well defined pixels then you have flaring/CA from the plastic lens.

Exchange it until you get a good one (better sample) but do not expect to see perfection at this price point, it simply does not exist. wink.gif

Also having your contrast too high can add to the flaring.

There was a few posts on one of the clone projector threads of either the Acer K330, Optoma ML500 , View Sonic , PLED W500 that talked about this problem with the convergence.
post #1602 of 2305
From what I remember even the clone projectors had problems with the convergence.

If I can remember that picture and the convergence is not as bad as the Optoma ML500.
post #1603 of 2305
Would having to much sharpness adjustment also effect that ?

post #1606 of 2305
The TriDef software (paid version) for owners of LG's free? or only for specific LG Monitors?
post #1607 of 2305
The blue/purple fringing is classic CA. Even projectors at double this price sometimes have this problem. It seems to be more common with plastic lenses than glass in my experience, but either can be affected.
post #1608 of 2305
smile.gif Unfortunately, nothing could be done, the first prism, the light passes through the thick glass and the 2 is not because they are plastic lenses glass, but the size of the lens, the lens is too small, and probably get a nice LG designers of multimodal a feed piece together the optics.
This defect, design trends, small, cramped enclosures.
Also to me, but I do not like watching movies does not really matter.

Plastic lenses are white, glass-reflective coating on, which is formed by vapor deposition, chemical elements at high temperatures, and that the plastic will not work. PB60G have plastic lenses but has PA70G glass.
post #1609 of 2305
Even in the benq w1080 thread, people are saying they see the same type effect, on one side green and the other red, and they seem to think in this price range, it's to be expected.
From viewing distance in movie or game or surfing the web, it's not noticable, but if it bothers you , get a 3,000 dollar plus PJ, instead of a 399 LED PJ. biggrin.gif
post #1610 of 2305
No, it is not only present due to a plastic lens but it is most definitely CA (flaring) if focused properly. This can happen even with all glass lenses and single dmd DLP's where there is no convergence error. The amount of CA can vary lens to lens as I have had three units and all three had different amounts, the first unit had almost none, second unit was similar to the one pictured above and the current one is very slight when focused as tight as possible (only the second unit could be seen from main viewing position by my better than 20/20 distance vision). I would bet that even the PB60/61 have some degree of CA present regardless of their light path design (which certainly can contribute). These are inexpensive mass produced units with questionable QC and people need to keep their expectations in check, this is not an excuse but sadly the reality of the market (I have seen a $10K pj with CA). If you want one of these units exchange until you are satisfied, some may even get lucky on their first attempt, just do not expect perfection.

post #1611 of 2305
You are right. Maybe I expect too much for this price. Or I am a little bit spoiled from the perfect screen of my notebook or my phone. It's my first PJ smile.gif
My picture setting are optimal. Contrast / Brightness 78; H/V Sharpness 70; Color 60. I got this values from Pictures Wizard, is really useful. Before all values were overdriven from me, believing higher is better. Watching Movies is fine for me, depending on the quality of the source. Text is readable, but not as perfect as on LCD screens. Most sharply is the "No Signal" below the LG cube biggrin.gif
I thought someone knows a trick or a hidden feature within the Service Menu to align the convergence a little bit.
post #1612 of 2305
A notebook screen is tiny compared to a 1280x800 image blown up 100 times to 100 inch widescreen. smile.gif
I had a 7 inch portable screen many years ago, and it was so sharp and good looking compared to 25 inch standard def tv's of OLD. You are packing pixels much closer together on smaller screens. I use bigger fonts on my 42 inch hdtv and on my PJ's so I can read everything without any straining at all.
399 for a LED like this was hard to imagine a few years ago. A 100 inch widescreen for 399 dollars is pretty amazing with 30,000 hours and good contrast ratio.
post #1613 of 2305
Speaking of $399.99 anyone know if this thing or something similar is going to be that price again anytime soon?

Nobody knows.
A not so good sign is they have on sale the LG 350T today , which is 300 lumen model on frys for 599 on sale, and in previous sale it was 399. The pa70g is the model to get , when it goes on sale for 399.
post #1615 of 2305
I know I've been looking for this thing. I found an Acer k330 factory refurbished for $399 so I might end up getting that if this never goes on sale again. What's the prognosis on this thing versus the k330?
post #1616 of 2305
As rgtaa would say "it's a no-brainer" (I think he must be a Gin Rummy player wink.gif)

Go with the PA70G

It has a better warranty, more lumens, larger housing with better cooling, better on-board speakers and wayyyy better color control via the built in menu.

Also, owners of the Acer K330, Optoma ML-500, Viewsonic PLED-W500 have problems with random annoying HDMI handshakes, that cause the screen to go blank and into a search mode for 5 seconds.

So now we wait lol
post #1618 of 2305
I couldnt wait for the frys deal to come back so I pulled the trigger on ebay for $485 shipped. The seller said it is brand new and he just opened it up because he heard about the focus issue. He says there is no such issue with this one so I'm hoping I dont have to return it once it arrives, wish me luck.

I have the Optoma ML500 and it has worse CA than shown in the pic above. I recently purchased a new pair of glasses (for my eyes) and paid a bit extra for high refractive index lenses, and they also have noticeable CA at the edges. It seems high refractive index lenses can suffer from CA quite badly. I wonder if the fact that these projectors have quite a short throw could be partly responsible, as perhaps a short throw lens needs higher RI?
post #1620 of 2305
So now we wait for FRYS to put it on sale for $399 with the latest shipment from Korea or whatever part of the world they manufacture them biggrin.gif
