It does seem to be easier on my eyes. I still get some strain if I watch a lot or watch it several days in a row, but not as bad as before. Still, I'm a little worried that I'm hurting my eyes so I'm not sure what I'm going to do. Other than that, I still love this PJ and don't want to give it up.

I remember when I was a kid and older, I would go to the movie theater and sit in first few rows, and I remember getting that overwhelming or eye strain type effect. Usually if movie theater was full, only a few seats were left in front rows. But if I sat mid way back, I was fine. So maybe experiment with how far back you are, or make smaller screen size if you can't move back and turn brightness down. It could be 120hz helps too, experiment with it.
I can get the same eyestrain if I'm too close to any PJ screen, maybe as experiment sit further back. I get that eyestrain on either my pro8200 or pa70g if I'm 5-6 feet back from screen, but if I'm 9-12 feet back, I'm ok.
How big a screen are you using, how far back are you sitting. Maybe also turn down the brightness. I notice on my LCD hdtv, I get eyestrain if it's too bright, like LOOKING into a light blub gives me eyestrain. smile.gif

Hey guys I use my pa70g with a htpc that uses nvidia ion. I made a custom resolution of 1280 x 800 and 120hz refresh rate. whenever I turn the projector on and it shows hdmi 1280 x 800 60hz eventhough its set to 120hz on my htpc. How can I make it show 120hz in the pa70g? Thanks in advance for your help.

I'm about to buy one of those android mini pc's, I'll probably be using Ubuntu on it. It supports 120hz 3D so I'm wondering if anyone has any experience with that and what I need to run it I'm a total noob when it comes to 3D.

Best screen gain for this PJ? and White or gray?
post #1925 of 2305
Here is a comparison of a 1280x720@120hz (16:9 aspect Ratio) vs 1024x768@120hz (4:3 aspect Ratio scaled to 16:9 via VLC Player) Image of the same movie in 1080p on my PA70G.

I post this to see the sharpness difference when projected with proper aspect Ratio vs f.e. 4:3 or even 16:10 (1280x800) which it comes natively with. I found it also doesnt make a difference if you scale it to 16:9 after source.

vs

Left is 1280x720@120hz 16:9 Just Scan vs Right is 1024x768@120hz 4:3 scaled on PA70G to 16:9 via VLC Player.

As you can see when you look at the details the left one is more sharp. In real the difference is more noticeable.

BTW i found the best way to change the picture settings when on 120hz. Normally it doesnt allow you to and all settings are greyed out.

Just unplug the HDMI cable and you can use all picture settings. When you have them set up as you like it plug the HDMI cable back in and they are saved and working for 120hz.

Decent ideas... though may be hard to play with in my situation. I sit about 12 feet back from a 70" (actually I think it's a little less right now) image, and my small room doesn't allow me to move back any further. I have brightness on medium, I guess the one real change I could try is putting it on low. But honestly, the eyestrain from this PJ doesn't feel the same as other times I've experienced it. Normally it would manifest as a headache with tired eyes. WIth this PJ, my actual eyeballs hurt, like I am damaging them. Never felt that before. Still not sure what to do, but thanks for the input. I did watch about an hour last night with zero pain, but I hadn't watched the PJ for days... it does seem to be less of a problem if I watch it sparingly.

Sounds like you are sitting far enough back, have you owned other PJ's in the past , or just seen them at other people's houses/movie theater's? I'm just trying to get a feel for comparisons. Because if you were at other people's homes , just like you watched 1 hour last night, and it didn't bother you, maybe other PJ's would do the same if watched for many hours. If you have owned other PJ's with no problems then eye strain could be from this PJ. I guess experiment with ways to avoid it or eliminate it and pass on the info.

What type screen are you using? Are you watching anything in 3D? Maybe experiment with a little light placed behind the screen, maybe the room is too dark? I'm just brain storming, and you can think of ways, settings, that don't produce that eye strain for you.
post #1928 of 2305
DaGamePimp, do you have a link to the settings you used for your calibration of the PA70G? I went through and did a search but was unable to find them.

Thanks.

I had an Optoma H27 (also a DLP, but bulb-based) before this one and never had any eye issues with it... and I watched that PJ a ton. I still have it and have thought of switching back for a while, but I really like the big image the PA70G gives me from the same distance (and higher resolution, the H27 is 480p... doesn't run xbmc very well). FWIW, I watched another hour last night and did notice some mild strain again (sigh). Never used 3D. I don't use a screen (projecting on a white wall, same as my previous PJ). I mostly watch with a light on unless I'm watching movie (weekends only). Thanks for the ideas... it just does seem to be this particular PJ. Weird.
post #1930 of 2305
As experiment, set up the optima h27 and see the brightness level of it and watch tv shows on it for a few days , maybe same series 2 hours a night, then set up pa70g and set the pa70g to exact same brightness level and everything else being the same, and watch a few more different eposides of same show. We want to see under same lighting conditions, same lumens, same everything, do you get eye strain only with the pa70g.

The only other person that had a problem with the pa70g that I can remember is the guy who had LG 300 lumen LED and he had said that on high level the 300 lumen PJ fan was very loud, so he used eco setting, if so, he would have been using maybe 100 lumens on screen? And then he jumped to pa70g which is 700 lumen PJ, and the medium setting doesn't have fan noise, so it could be just brightness issue, not sure.

Others have said that PJ's that give more lumens output can put more strain on eyes, any bright PJ bulb or LED.

Your optima h27 when I read review said in eco mode it was very low lumens of around 200 lumens. Is the pa70g brighter than your optima h27 in your room?
post #1931 of 2305
Hey it'll be a sacrifice, but I can always trade you for my Optoma PT100....with a rating of 50 lumens in Bright mode, I can guarantee you'll never get eyestrain from brightness. However, the 858x480 resolution may give you a headache lol!

I have a mid 2011 macbook pro with a Radeon HD 6750M card, can I get that to run 1280x720@120hz 16:9? I just switched to a mac and am so lost.

I would also like to hear what people are thinking when it comes to buying an Android TV. I 've been thinking of picking up this one
http://liliputing.com/2013/03/first-android-tv-sticks-with-rockchip-rk3188-quad-core-processors-arrive.html but I don't want it to look as crappy as my Xbox does.


Also want to agree with the guy that says there needs to be a wiki or something for this projector. I have been reading this thread for two hours and most of what I have learned is that there isn't a good translator and some guy posts too much so I should block him. I am hoping I can figure out what you guys have because I am about to sell this projector and buy something that works out of the box but I love the benefits of the LED!

I have been suggesting a wiki SECOND post for this site for a while. This second post in each pj thread would give all of us useful current info for the PJ, calibration settings, screen suggestions, accessories what work (like ceiling mount, ND filters, etc).

Any member could add to or edit that post , so best info is given.

This would be very useful for everybody that owns that PJ and others that are thinking of buying it.

Having to look through 50-100 pages of info on PJ is time wasting.

Other sites do this, and if you are MOD or are friends with mod, can you discuss it with them. I don't see a downside to having second post wiki for all this stuff. Because it could also contain, lastest firmware, and other very useful info .

p.s. As to your comment about Android on a stick being as good as xbox? Do you mean xbox 360 or first gen xbox. Some people still use first gen xbox for xbmc. If you mean 360, I think 360 looks good with this PJ. I do have android on a stick but not quad core, but uhost a1 that I wrote about in thread. It does work with this PJ too, and it has wifi built in and plenty of apps to use and plays 720p videos no problems and simple games like angry birds. What is nice about it is that it gets powered by the usb port on the pa70g. So easy to carry with you for portable use. Maybe do research on the quad core version.
Remember the pa70g is a 720p PJ, so, any of these sticks should not have problems with 720p videos. I do not use it as much as I thought I would because I'm mostly in room where I have 360 and full PC in room. But it does work and it is very cool for travel. smile.gif

only had this projector (LG PA70G for a couple of hours and it's awesome. I have only tried a ps3 game and wow I was blown away. need to get it all set up and I will post back
post #1935 of 2305
ok I have a small problem and maybe one of you can help. I can't seem to get my ps3 games to play on this projector PA70G (it worked at first and then my one ps3 died). it will play all my blu-rays ect fine.. but it will show the beginning of the game and then you go to play a game and it will not load / freeze and I have to power off my ps3 (on my sons ps3) I let the ps3 auto select the display setting ect.. also could using an 1.4 hdmi connect cause this??. any thoughts thanks

post #1936 of 2305
Maybe try setting display output to 720p (and disable 1080i and 1080p)? The projector would be scaling anyways, and it does not support 1080p, so you might try that and see if it helps. My ps3->PA70G experience over both component and HDMI have both worked great, and that is how I have my PS3 output configured.

The one time I did have an HDMI sync problem, replugging in the HDMI cable at the projector seemed to get it synced back up.
post #1937 of 2305
ok thanks, I think it has to do with the last ps3 firmware update. I had to get my ps3 fixed today so I barrowed one that had an old firmware version and it work fine weird. anyway thanks
post #1938 of 2305
ok so I am pretty sure that it was the firmware that was keeping me from playing my ps3 on my lg pa70g projector I updated the ps3 and everything is good. I watched march madness from 12 to around 1am on this projector along with my buddy from out of town and he was blown away, said this was much better then bw3's ect.. that have projectors . in the morning before the basketball games he watched the dark night rises on blu ray and he said it was like he was back at the movie theater watching it.i got the picture dialed in pretty good will use a calibration disk to do some touch up on the overall pic. some have stated these have focus problems, mine does not seem to have any, the build date on mine is January 2013 so it's a very new. I purchase my pa70g from fry's.com overall for a 720p projector I am blown away by the picture. I have a 57inch crt rear projection tv as my main tv and a 51 plasma to compare and this is right with them as far as picture goes. very happy and will post some pic in the next few days. smile.gif

That would be so helpful!

Sorry, Yes I forgot the popularity of the old xbox with the XBMC group. I have a 360 slim and apple TV and I would really like to use my Macbook pro that I mentioned earlier with my external bluray but I still don't understand macs and don't know the best configuration. Also wondering if it was possible to do the 1280x720@120hz 16:9 on my Macbook!

Thanks for the input on the Google TV stick.

Hello, has anyone seen the pa75u at best buy for 799.95? Is this a new model? Or is it the same with a best buy #? I have the hx350t and it's perfect. Just looking for a brighter image and better contrast, using on a 106" screen. Thanks.

DANG!!! I thought I'd be the first to spot this in the wild, but guess you beat me to it haha, it's 749 now, it's the same projector but the PA75U includes an HDTV tuner, excellent price for a unit with a built-in tuner...but taxes puts it over the 800 mark:D
post #1942 of 2305
bestbuy PA75U




photo 8589114_bajpgcanvasHeight500canvasWidth500.png



now the only bad news is that if this projector is carried exclusively by bestbuy, there won't be any price drops anytime soon, I hope that's not the case

the good news..bestbuy doesn't charge a re-stocking fee, so if you get a unit with bad focus, you can take it back no questions asked

Well that kinda sucks. I was hoping for a new model that might had the focus problem fixed. And I'm nervous about plunging into a big purchase from best buy.
post #1944 of 2305
IMAG1389.jpg 279k .jpg file

i returned my pa70g to frys and was able to get a full refund, ended up purcasing a 47" lg lcd , but i do really miss the projector for movie watching lol

i would defiently buy another one if i had a dedicated dark movie room, the fact that it didnt look super awesome playing xbox 360 and the fact i dont like darkening my basement living room for daily tv watching because i prefer watching tv there, eventually made me return it. not bad at all for a $500 projector, i think if it was 400 i wouldnt not have been able to get myself to return it. watching "the gaurdians" on it made it very difficult to return lol

Im not saying it has focusing issues, some are saying that the 11/12 and later PA70 units have pretty good focus, so it's possible that they (LG) has fixed the issue, but it's good to know that bestbuy will give you a full refund in case you're not happy with it.
post #1946 of 2305
I found a better example for native 16:9 resolution via inf file vs 16:10 or 4:3 scaled to 16:9. Here you can clearly see why i was raging about this projector a few pages ago.

Differences of the Settings of both Pictures are: Left is 1280x720@120hz Black High vs Right is 1024x768@120hz ->scaled to 16:9, Black Deep.

See yourself and understand why i changed my mind smile.gif

vs
1280x720@120hz Just Scan - Black High *************1024x768@120hz 16:9 - Black Deep

Both pics are closeups cause the focus issue is not too good viewable from a proper distance. For me the focus issue was not a lens problem but a firmware that wasnt able to scale it correctly from any source format. So i had to use the correct source format to negate the firmware scaling for having perfect focus now.

Note it was impossible for me to get any source to display 16:9 higher than 50hz on this projector without the inf file and a custom resolution. My tv Picture from my tuner is still unsharp cause it can only send 4:3 which has to be scaled to 16:9 on the PA70G resulting in a slightly unsharp picture. But since i dont watch much tv its ok for me.

here are a few pictures from my LG pa70g. all pictures were taken with a 5mp camera with flash off no other settings changed (any blur is from me/camera not the screen the focus seems to be spot on for the whole screen with projector build date of JAN. 2013). I am very please with the overall picture of this projector for under $500 the images are projected onto an 106" screen.

Hi all,

There is a very professional review of the LG PA70/72g on cine4home (in german).

Can't post direct link but u'll find it on the homepage.

http://www.cine4home.de/index2.htm

Neither direct link and google translate worked on their site, sorry.

Just read the review and think i'll order one ! Seems very promising.

Definitely not a toy smile.gif

Hi,

Could you please post a link for right glasses . There are a lot of type glasses.
Thank you.
post #1950 of 2305
From reading through most of this thread, it sounds like many of you are running a HTPC directly connected to the PA70G as the primary source. Is anyone running this through an AVR? I'd like to know how this projector preforms without the added image adjustments of a PC video card. I'm envisioning a single HDMI out from my AVR into the PA70G and all of my sources (blu-ray, PS3, cable box, etc.) running into the AVR. Does anyone have that setup and are you happy with it? Is the image crisp or does the AVR processing and screen ratio adjustments augment the image enough to degrade the quality of the picture? I don't want to buy this projector if I have to rely on the 3W speakers for sound.
