LG PA70G LED 1280x800 700 Lumens. - Page 60

post #1771 of 2305
displaylou,

Indeed there are many factors involved so we cannot make definitive conclusions based upon those shots alone. It's likely that both of our pic sets do not show what it looks like in person.

I will say that my game room is far from ideal as it is all off-white but I have no ambient light as the only window in the room is totally blocked out by dual blinds and blackout curtains.

Also my camera is not a DSLR, just a inexpensive $250 msrp Sony compact and I am using it in Auto mode, no manual adjustments to improve the results.

Those pics are without the Darblet active. Maybe I'll take some split screen shots with it later to further entice ThomasK into making the investment. wink.gif

My PJ just came fom fry's. I got a January 2013 build! I'll post some shots of it when I get it all set up.

So far this projector is way better than I thought it would be.

That's a GOOD news!......
Maybe LG already leaned their mistakes and able to correct and fix it. I hope so, that the 2013 built will be a no more focus issues.
post #1775 of 2305
Good to hear indeed but I would say it is far more likely that he simply got lucky with a decent unit versus LG making corrections. wink.gif

Or maybe he just actually kept his expectations in check at the price point and it exceeded them (although this would be a very rare occurrence around here). eek.gif

I agree she is not so ugly face in fact very beautiful.
Also it's positive news that midnightchannel is very happy with the LGPA70G and a good focused unit.
When I do order one I will insist that they look and check to make sure it's a later build unit.

FRYS ? if you build it they will come, now build us a nice deal of the week at $ 399 biggrin.gif with later build units please.
post #1777 of 2305
Good to hear from you Pawel and hope your doing well biggrin.gif

I would guess if the later build units from LG has good focus that we won't have to bother with modding the projectors or fixing the problems.

Pawel I read in a old article about Texas Instruments DMD chip for rear projection TVs called The SmoothPicture™ Algorithm: An Overview by David C. Hutchison, Texas Instruments, for DLP TVs.

Would this DMD be the same as in these generation projectors ?

I read that in those DMD chips that the lines between the DMD mirrors are either smoothed out or the picture is soft.

The Smooth picture technology displaces the optical image by 1/2 pixel by utilizing each DMD mirror to display two pixels on the display face therefore results in a smooth film like image without pixelation while displaying all the image information from the video source.

** Oh and a suggestion would be to try some darker material above your screen temporarily and see how much your image improves since it looks like you are probably washing out partially from all that ceiling reflection (since the screen is so close to your light colored ceiling). My ceiling is light colored as well but it is the 'popcorn' style texture which is less reflective and it is also several feet above the top of my screen.


I'll let you judge that one for yourself... wink.gif

Great pics Jason! Mine really looked dull compared to yours. But consider the fact that ive taken them while daylight reflection reached the screen since i couldnt cover all windows. In the evening its not so washed out and more like your pics. But still i dont think my projected image is as good as yours now. Maybe its cause of the ceiling reflection (my wife wouldnt allow me to blacken the ceiling for sure^^) or its cause of the different quality of our PA70Gs.

Any idea how i can minimize the ceiling problem without using black cloth but anything less ugly? I cant put the screen lower since our walls are barely 2,40m and the screen is already 1,50m high + sideboard below. I will do some more pictures in the evening without daylight reflections on the screen then lets compare again maybe its more close then.

And i found a shop nearby which has alot of DIY lenses for projectors but i would need to know the throw ratio, focal lenght or something and if i need a special DLP lens or if any lens would do it.

DLPProjectorfan, do you have any idea on the specs of the inbuild lens of the PA70G?

Real Cinema: On
Colour Scale: Breit (english word maybe large)
White: 10
Colour Temperature: Middle

Playing back a 720P movie at 1024x768 resolution will only give you 1024x576 resolution.

I would rather set it at 1280x800@60Hz. Also more picture settings are available at 60Hz than 120Hz for me.

Edit: Also keep the sharpness settings close to 50 as possible + Auto keystone correction should be off and set to 0. First try to get a sharp picture with the focus wheel before considering to go above 50 on sharpness settings.

I did a web search on the specs of the LGPA70G and the lens and the only specs I could find were the ones that are on the LG's web sight for customer support.

Unfortunately there is not a whole lot of information on the actual lens of the LGPA70G out there frown.gif unless you had the actual lens in hand.

Those who have taken you projector apart and took the lens off what does the lens and the lens housing have to help us determine the specs ?
post #1782 of 2305
If you could afford it there are screens now there that work well even in ambient light called Black Diamond screens.
post #1783 of 2305
Hey DLPProjectorfan, seems to be a very good info. It will definitely be my next screen but only when i have some cash left in the future. Darbee Darblet, Black Diamond Screen and such things are exactly the kind of infos people are interested to know about cause we all are perfectionists when it comes to such detail improvements. smile.gif

Btw im using the XGA resolution after testing it to be no difference in movies compared to any other resolution + it is the only resolution that lets me select 120hz which gives me the best motion flow on the PA70G. The 24p setting is not perfect on this projector and far from 100% fluent. For the settings you just have to set it to 60hz set it up as you like it and go back to 120hz and it is saved. At 24p you can set up every detail in the settings, in 60hz most of it and in 120hz nearly nothing.

And here are my pics from evening. In my opinion when i viewed it live its exactly the same as DaGamePimp has it on his pictures only my poor cam is way more crappy than his but i think you can see what i mean. Biggest Problem on my 50$ cam is that you have to hold perfectly still to not get an unsharp pic out of it which is nearly impossible...cause your heart bumps and such lol.








This pic shows my mounted PA70G and the problem with my cam.

Posting few snapshots for my LG PA 70G. 7.5 feet by 5 feet screen.
Few test screens and few black and white movie ( Casablanca ) photographs. I did not see any BW snapshots.
The PJ is in maximum energy saving mode. The camera is held in hand.
( PJ bought on DEC 21 2012 Frys sale for 399$ )

To bad your windows are not like the electric windows on the 787 where you push a button and the electric current goes through the I think some kind of crystals that causes the window to go dark.
post #1787 of 2305
there's hope for those of you waiting for the 399 price...I was at my local frys this morning and it appears that they didn't sell any of their PA70's @ 499, the huge pile is still there. so, my guess is that they will have to cut the price to 399 if they hope to get rid of them. remember, patience is a virtue:D

I am from Bihar(India) and contemplating a Pj for my home.Narrowed it down to Acer K330 and LG PA70G.Also A cheap Egate P512 is in my mind.The problem is that I need a crystal clear picture on a Screen at least 120" diagonally and most of the posters here as well as on other forums have posted their experiences on a Screen less than 100".Here got a Quote of Rs. 53,000.00(around 950$) for LG and 39,000.00(Around 700$) for Acer.
However Egate P512 is pretty cheap around Rs. 25,000.00(450$).But there are no Resources for their detailed performance.Will You Guys plz shed some light on my problems.

Wow the speccs sound awesome. LED+LCD is my favourite tech for projectors even the contrast is by far not as good as with DLP. Its sharper, extreme bright and has perfect colours. If the LCD panels are from Epson and the true Lumens are at least 1/2 of the 2000 from the advertised speccs it should be an awesome, way better projector than the PA70G or the Acer K330.

On the other hand i remember there were some no name projectors with better speccs than the named ones in the past which were not only way off from the stated speccs but also extremely poor in QA and performance.

Anyway heres an example for a only XGA LED+LCD projector with true 1000 Lumen brightness and its performance even at daylight.

http://www.avsforum.com/t/1263464/samsung-sp-f10m

Its actually the best overall tech and if the indian model now even has a better resolution it sounds very tempting even for me. BUT I wouldnt buy no names without any serious comparison to a known product. The Samsung had alot of positive reviews, way more than the PA70G for its time so it was a good choice. Now i still wish i had waited for a better model but the PA70G and didnt sell mine... anyway one day there will be either LED DC3 DLP Full HD projectors with 1k+ Lumens or my personal favourite LED Full HD LCD Panel projectors with a proper iris for the contrast issue. Until then i wont try any of these mid age products again.

edit: My pics from the PA70G are at daylight and in darkness on a 110" screen so its close to that what youre looking for.

Here is a link for another no name product with even better marketed speccs but it was crap in the end since the speccs werent true at all.

I am not a theatre going guy and also a lazy one owing to the nature of my Job.Probably last time I saw a Movie in a Theatre was at least 3 Yrs. back.However My eyes and Ears are very sensitive.I cannt stand Inferior quality Picyure as well as Sound.On the Otherhand ,My brother having the advantage of being in a Metro(New Delhi)and also being a Moviephile frequently visits Theatres and Multiplexes.His assessment was that the Pj is a very good One though a bit bulky as compared theAcer and Lg.I am a Novice in this area and as this is going to be my first Pj,would you plz tell me what to look for especially as the brightness of the set is more than enough and it has a crystal clear picture as per my Brother.

Hello folks,

i just received my PA70G and i am very astonished about the picture quality, coming from such a small piece of electronic. Last beamer i owned, was a Electrohome CRT with the size of a stardestroyer.

Now i wanted to ask, if someone is experiencing a buzzing sound, on the side where the lens is mounted?

It seems to be dependent of colortemperature; if switched from "warm" to "natural", it changes its frequency and volume.

It can alreaxy be heared after switching on, right before the fans kick in - so i assume it has something to do with the power supply of the LEDs.

So is it "normal" and i have to live with it or shall i ask for a replacement?

best regards from Germany

Thanks for your help!

Display the image in which any, or directly from the projector, or the PC, or plugging in HDM and some player that displays image files, I am using DVB-T tuner for watching HD TV and movies from the HDD, it also displays photos and paintings.This is because it is 1080 does not matter because I just like watching a movie in Full HD then it is converted to a resolution of the projector, it is not a laboratory and proving you do not have the physical theory, only display the image and see if it is correct.This will allow you to control the image subjectively regulate the parameters and the color image, white lines on a gray and black on a gray allow you to adjust, focus, horizontal and vertical, and the gradation of black and white contrast and brightness, color bars used for the reproduction of colors so that you fit in, the grid serves to check the sharpness.

smile.gif Take it easy you do not need to do anything about it, the natural, the sound, the buzzing choke coils in the system power LED, as we all know is a switch mode power supplies, depending on the white balance changes luminous intensity of individual LEDs.It's true LED projector displays an amazing picture, which can not be obtained in a traditional projector. In time they will ever brighter.The standard picture modes are not suitable for the very reason I would recommend to set their own expert mode and the picture will be even more astonishing.

Thats not easy to answer for me since im more an IT guy but a projector geek. Here are some others around like Pawel, rgtaa, DLPProjectorfan, DaGamePimp etc who are more into this than iam.
But as far as i know you have to know about the following points:

- Sharpness (which shouldnt be an issue with proper glass lens focus + lcd panel technology)
- Real Brightness Output (not the theoretical brightness of the inbuilt technology) needs to be measured by someone
(for example the Acer K750 which is listed as 1500 Lumen only has 600-700 after testings when i remember correct, so the same as the PA70G)
- Resolution: is it really 1280x800 natively or does it only support this resolution?
- Convergence/CA: most of these cheap no name projectors are having hardcore convergences ive seen. Even the PA70G has this but not as extreme in my opinion.
- Colours: is it possible to get near to D65K colour temperature best seen when compared to a TV or anything else which has the correct adjustment.
- Cooling / Loudness: does it have a closed cooling path where no dust can get inside the lightpath? How loud is it at which brightness setting?
- Contrast/Black: LCD panels have lower contrast and blacks naturally than dlp and you have to ask what solution they use for the dynamic contrast. Pulsing didnt work too good on the SP-F10M and i dont know how an iris would work combined with LED/LCD lightpath. But still if it is near to 4000:1 it should be enough considering the negative aspects of dlp such as rainbow effects and other possible eyestraining issues.

Id say if you can send it back try this Egate 512 and compare it to another known projector and post your subjective experience. But for you being sensitive as you say when it comes to quality i doubt this Egate can compare to even the PA70G which is probably the best all around LED HD Projector if sharpness is not too important for you and the price is around 400-500$. Im only not happy with it cause i payed alot more. For 399$ or even 499$ i would be very happy with the PA70G even with its flaws.

My HT dream still is a LED Full HD Epson LCD Panel 1500 Ansilumen projector with working dynamic contrast by the pulsing of the LEDs but controlled by better chips (each for every LED).
My 2nd HT dream would be LED Full HD DC3 DLP 1000 Ansilumen projector without a colourwheel for green and proper cooling.

Hello Pawel,

thanks for your fast response and explanation. I think i can live with the buzzing - but only because i know now, that it is normal and not a problem of my PA70. I will take your advice and get on the journey through the expert mode settings, to make the picture even better.

So the buy decision is still kinda a hit or miss with this unit it seems? I want to buy my first theater projector and still struggling between this and the pro8200...

If it were ME I would go with the 8200 for home theatre use. For everyday use( like a TV) I would get the LG. I just bought the PA70 and have been putting it through its paces. It's great for what it is,,,but it is nowhere near as bright as my older sanyos in the 1500 to 2500 lumen range. The viewsonic has a zoom , The LG doesn't. I have a january 2013 build and it doesn't seem to have to off focus problems that the unit has been knows for. It also has a much more colored feel about it and is a softer picture than i am used to. On a smaller screen it is viewable during the day but on a larger screen much is lost
I might add that I am going through the VGA port. I haven't tried the component or the HDMI ports yet but so far all the images I seen from this projectors gives it a little more of a red ting than i am used to.

Just my Two cents
