LG PA70G LED 1280x800 700 Lumens. - Page 27

I also have the gyrating picture that Pawel addresses at the end of his post, which I'm guessing could be from the loose lense cover. I'm coming from a Viewsonic PLED 500, and while that had major focus drift issues, I always felt like I could control the focus accurately. Using the focus knob on the LG leaves me feeling like I have to try and try again to have the thing focus well. I'd like to try and get the lense cover fixed in place before I start tinkering with screws. Could the variable orientation of the lense cover (some cocked by consistently, some changing position) be the main problem that is being compensated for with the screws around the lense?

Love the lower fan noise of this one so would like to make it work.

Oscillating image is another issue who is to analyze far I have no information on how the lens is designed PA70G but it seems to me that, there is something wrong with the fastening of the lens adjusting sharpness as if instead of ring spinning move along the axis of the lens I parallel to tilt the lens this lens rotation ring with forward and backward causing lifting and dropping the image if it is not understood how can I draw a diagram I imagine the operation of this lens I think that it is associated with a white roll ring placed in a groove adjusting sharpness. Aiming the lens in my hand I could solve it but for now you need to wait smile.gif.I think it also has some effect on the same sharpness not only to shake the image, I gently tapping with your finger causes changes in Focus.

Just my two cents regarding focus, using it strictly for home theater purposes: back in the days of WSVGA we used to deliberately slightly defocus the projectors to reduce SDE. While WXGA pixels are considerably smaller, I would probably still gently defocus the PA70G with the same goal in mind. The way mine looks is just about perfect for video and movies. I watched about half of the last Star Trek BR movie last night and frequently paused it on high detail scenes to have a closer look. To me at least the picture looks more than satisfactory, with small details still easily discernible from a regular seating distance without being noticeably blurry. I ran the "Picture Wizard II" setup on the projector, which goes through a basic brightness/contrast/hue calibration similar to the THX calibration you find on many discs. While this automatically turns the projector to full brightness and makes the fan whine, even after switching back to medium the brightness was still good and the flesh tones looked nicely balanced. Full screen faces looked beautiful, with subtle skin color gradations and no aliasing or stair stepping discernible. The face contours looked perfectly smooth from temple to temple, something that always made my old Optoma H31 trip up. Whatever the shortcomings of the diagonal pixel lattice may be for data, I must say I prefer the look for video.

Does anyone make a ceiling mount for this projector? Mine arrived today.. So far I am impressed. It can not live on a tripod:(

Thanks

Erick
post #785 of 2305
Since it has both a set of four mounting holes (one inside each foot) and a tripod thread your mounting options are pretty massive. Just about any universal ceiling mount should work, as well as tripod mounts that are ceiling attachable. My old Optoma H31, much bigger than this unit, was ceiling mounted for a long time using one of these:

Considering how light the PA70G is you could just Velcro it to the ceiling biggrin.gif
post #786 of 2305
so the slightly not perfect focus could be a pro for just movie watching?

my concern is eyestrain, I figured any out of focus portion of the screen would cause eyestrain for a two hour movie session.

is this not the case?
post #787 of 2305
Funny guy!smile.gif I am going to velcro my kids next to the projector:) Thanks for the heads up.. A speaker mount will work.
post #788 of 2305
If you get the one I linked, the "cup" half of the mount that you mount to the projector has a hole through the bottom of the cup. Go to Ace Hardware and find a screw of the right size and pitch for a tripod thread (1/4", 20 threads per inch). Take the mount with you and make sure the screw sticks out just enough to engage the projector threads, about 1/4" or so. Screw should be less than $1.

Regarding the kids, I'd assumed like any jaded parent you'd already done so and had some left over Velcro, hence the cost saving suggestion.

anyone have any input on this vs the casio or other sub 1k led laser hybrid ? The lumens are much higher in the 2k+ range

Got to me this time PA70G new factory box and covered with a revelation smile.gif picture can accept as correct smile.gif 99% Focus is famous cross left top and right down slightly spicy but not in comparison with the previous projector is a revelation, the regulation does not bounce theory to suspend or using smile.gif but as soon as I find the time I need to take a look at the construction of lenses for rotating aperture. I expect the lens so you can spin to detach the front lens group inside the group remain adjusting focus and the rear lens group. Another way that could not be inserted outside a changing focus ring rotation, except that I think it is crazy front lens ring and the rest of the plastic lens is inserted from the front or inside a rear locking ring group in the front of the lens.Test Pattern is correct on the whole surface not only that they line doubling pixels in the corners are fuzzy Lightly what confirms me in that the aperture changes the depth of field.

Hi everyone!
My application requires a small projection distance between projector and projection plane. Could anybody make a quick measurement of the smallest possible distance?
According to the specification of PA70G projection distance should be 0.90-3.06 m (projection diagonal 76.2-254 cm). But in the datasheet of PA72G under ‘projection diagonal’ entry is said 50-254 cm. According to LG both projectors have the same optical unit. This would mean in order to get projection diagonal of 50 cm a smaller distance then 0.90 m is possible.
I would be very appreciated if anyone could try this out.
Thanks in advance.

Depending on your application a security camera mount might work.
If you go to Amazon you can pick up a Videosecu mount for $ 6
post #795 of 2305
I even used a microphone boom, but it's not working out to well because of the weight of the projector causes the microphone boom to slowly move down while watching anything.
Ohh well, that's $ 25 wasted.
I should got the security cam mount in the first place from Amazon for $ 6 but I was in a hurry to get things set up.

I haven't gone through the manual , but i use this link
http://www.projectorcentral.com/LG-PA70G-projection-calculator-pro.htm

I found from there, that the throwing distance is less then the image diagonal that my projector gives !!!

Miles cheaper than the 1080p Viewsonic led.

I would love to see a shoot out between the Viewsonic pro9000 and the lg pa70g, just for fun.

Is it the whole week ? I'm waiting for some money to show up on my account before I can buy. I been waiting since Black Friday.
post #800 of 2305
if you finance it over 12 months its only *drumroll* $33.25 a month!

crazy price talk. http://www.avsforum.com/t/1440601/lg-pa70g-399-at-frys

According to this calculator even throw distance of 35 cm should be possible. But is the image still in focus?

I must say I'm very tickled with mine. I'm coming from 7 years with an Optoma H31, which I liked very much at the time, but SDE was always quite pronounced. This thing by comparison is silky smooth. While the soft focus no doubt plays some role in it, the screen door grid is nevertheless much more subtle and disappears completely a few feet away. It's amazing to get such a massive picture upgrade along with a big drop in price--the H31 was $1100 in 2005 while the PA70G was $399 last week.

I was seriously torn between that and the Viewsonic PRO8200, price and maintenance-free LED versus resolution and brightness. In the end the cheap bastard in me won at the $300 savings rolleyes.gif I honestly don't feel shorted with this thing, it projects an excellent home theater picture. No buyer's remorse at all, plus I paid so little that I can easily relax and enjoy it while waiting for affordable 1080p LEDs. While the H31 was considered a very good HT projector at the time, with good colors and contrast, the PA70G is much, much better in those areas. Subtle color gradations over large areas are much smoother, with much less noticeable transitions between shades. I'm also blown away by the configurability of this thing in the Expert settings. I'm perplexed by people criticizing the PA70G for not being very configurable, I can only assume they just saw the Simple menu and nothing else. In the Expert menu you can configure minute things that many projectors only expose in service mode, such as detailed individual control over each color.

A few suggestions for new owners:

- 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 (Minimum savings--whatever were they thinking using inverse language like that?!)
- for movie modes turn off dynamic contrast, it ruins colors
- use medium brightness, max is simply too loud, regardless of audio going on
- fiddle with the Vivid settings to give you the maximum brightness and "pop" for news, sports and other incidental ambient light viewing. While it is the brightest LED pico around, it's still not bright in absolute terms, so with some lights on and people milling about you need a little extra oomph. Vivid can do that, it will make the picture look like a stock store plasma that everyone goes gaga over. Make sure to turn ON dynamic contrast, that's entirely appropriate for this mode. Incidentally, you get more perceived brightness from the right picture mode than from just turning it to max brightness.

A small gripe regarding all the focus and small text display issues talk: this is a HT forum (http://www.avsforum.com/a/about-us), people come here to talk about displaying video and movies, not data. No doubt there are much more appropriate forums for discussing business projectors. While it's true that I wouldn't buy the PA70G to display a Windows desktop because that's simply not its forte, that is NOT why I bought it and why I frequent this forum. Its very minor focus and small text display issues are all but unnoticeable while displaying video, so frankly I don't give a rat's behind about that. Again, this is NOT a business projector forum. It's ironic that TI and all the manufacturers are targeting business use with these picos, when in fact this chip's strengths lie in video and not data. But as long as I can buy it for $399 I don't really give a said rodent's posterior either.

Thinking about upgrading to this from an Optoma HD70. The HDMI port went out on the HD70 due to lightning and I was just about to install an HDMI to VGA converter when I saw the deal on the PA70G. The projector is mounted on homemade ceiling mount (acrylic plastic and ceiling fan kit) about 15' from screen with a 120" diagonal picture. Can the PA70G be installed on same mount, or would I need to reinstall everything to get same size image? Usually watch movies at night.

Advice needed...

I was able to view an 70g today. I didn't get to adjust any of the settings, it was just as it came out of the box, but the skin tones were not good. It's hard to explain but the highlights were blown out and all the skin tones seemed to wash together. Not very sharp at all (and it was in focus).

I was comparing between the Epson 3010, hoping that the LG would be close enough, but it was miles apart. The room had medium light.
  1. Does my reaction and description sound plausible based on your experience?
  2. Is there burn in time for this projector?
  3. Could the settings be that bad?
  4. Other explanations?

I really appreciate the feedback.

Thanks,
LB

Was it at a fry's store. I am hoping my fry's has it in the presentation room.

what was the source material, bluray dvd sd broadcast? was it all through hdmi?
post #808 of 2305
So this projector has no offset correct ? It just shoots the image straight out of the lens, not at an upward or downward angle ?

It was through HDMI. And I had the epson to compare it to so I know it wasn't the signal.

I bought this projector at frys on this morning, but still haven't opened it...why??? glad you asked, well, I really want the PB61U with the HD tuner, 500 lumen but bright enough for my application. just gonna keep it for the 15 days and see if the darn PB61U will go on sale, if not I will keep this one. GRRRR... anyone has one that wants to trade??? sealed unit with frys receipt, if you have one it must also come with receipt:D
