Thanks man, since 0.8 gain looked too dark for me I am actually considering the below 120" options now:

1) ELITE SCREENS fixed frame projector screen 16:9 ezFrame 266 x 149 cm, 16:9 format 120 inches, 3D or 5D CineGrey cloth, 1.2 / 1.5 gain - £699 / £899

2) QualGear QG-PS-FF6-169-120-W 120-Inch 16:9 1.2 Gain 4K HD Ultra Fixed Frame Projector Screen - White - £256
https://www.qualgear.com/products/ps...-white-12-gain

3) Duronic Projector Screen FFPS120/169 | 120-Inch Fixed Frame Projection Screen | Wall Mountable | +1 Gain | HD High Definition Image | 16:9 Ratio (seen some pics on Greg's and looks good)
https://www.amazon.co.uk/gp/product/...AXPSKRV0&psc=1

Any ideas of which one could be the most cost/effective?

Thanks!

I would be suprised if any painted material performs as well as an ST100, alot of engineering went into that material and advanced manufacturing is needed to make it. They're generally 3k for typical screen sizes and there's a used market as well. The parallax at 4k provides a similarly matte and artifact free surface with the added bonus of above/below light rejection and shifting contrast for improved black levels, well worth the price. The screens invisible with these materials, I think alot of people dont realize how grainy and flat the cheaper materials make the image look, a pixel should look solid and uniform, not like a little pile of sand.

I can only imagine what the mico40 would look like on a full sized st100/parallax. It already has incredible dimensionality and removing any hotspotting/gain artifacting would make it look like actual 3D. I'm pretty sure rgb dlp + st100/parallax = perfection(aside from 0-1% apl black levels...). Upgrade path for me is still a parallax.8

Yes...maybe a lot do not know....until someone lets them know. Gosh Dude.....I was painting "Invisible" screen surfaces back in 2003, and getting them compared to Stewart 130s on all aspects....and guess what...the ST130 was NOT as smooth a surface back then. The proper painting of a screen delivered smoother, more superior images than virtually ANY Mfg screen, making 720p and 1080i & 1080p images look like they came from a CRT. Believe it! It's all of it AVS history.

All the nice things you say about the Stewart I've been helping Members achieve for over 17 years. And I betcha a bunch were even less confident that you at first.

One needs only to want it, listen to, and accept my advice and help and they WILL succeed. Otherwise...I'd'a been forgotten History long before the last Decade was out...the one before this last one. And I'm not alone. There are several others on the Forum who have stayed the course...with varied and various approaches. Some advanced...some simple.

Lemmie put it this way....I've been eating the Lunch of $3-$5K Mfg Screens for years...and showing other totally inept NOOBs how to do likewise, with such screens achieving surfaces that were "HD" and "4K Ready" long before any of the Screen Mfg took up those ideals. And it's not made me popular with the Mfg Screen advocates on here...or the Mfg. But those who go into DIY with a open mind and a willingness to try virtually always come away happier than they ever thought possible.

That has been...is...and always will be the only thing that matters.

@MississippiMan thank you for the input, that's very reassuring.

If its convenient could you provide(or direct to) close up photos like the attached to show pixel structure and how light interacts with the surface?

I've been unable to find these kinds of photos of painted screens, usually just photos from the viewing position of static video.

When I return to my office late Sunday I can check through my two Hard Drives (2 & 4 Terabyte) where I'm sure I have some older examples in 1080p and EShift 4K.

Hopefully......otherwise I might be able to beg some examples off of some current members with Native 4K units.

See ya on Sunday...I'm off to West Arkansas to do the impossible. Retro-fit in a Pre-Wire for a 7.4.2 system, install all the Speakers, Hang a Dark Energy Screen, Install a NX7...and manage to get some sleep in between it all. A 48 hour burn

Ceiling mount

Folks,

Have the LG HU70LA and have been using it on a coffee table.. am getting set to mount it on the ceiling, have the projector mount ready to attach. Question is will the projector automatically invert the image? There is not control parameter in the settings to do so, just front vs rear projection mode. Any experience/knowledge would be appreciated

This function turns the projected image upside down or flips horizontal.

My old PF1500 does it automatically, so I am sure the HU70 will flip once you put it upside down. And, as noob mentioned, there is definitely a setting for it in the menus though it's stupidly buried deep.

p.s. Two posts in 18 years? That's some serious lurking!

Hi there! Quick update on the screen:

- last week received both Vivid storm 0.8 ALR grey sample (too dark image) and XY 8 multi samples (BC way too dark, best performances were with 1.0 white matte 4k material)
- this week I will receive 4 samples of CineGrey 5D to try with the projector. If it performs great, might spend more and get this one.

Now, if CineGrey is still too dark...I will opt for a white matte cheaper option with electric pull/tab tensioned.

1) White matte electric pull down with 1.3 gain, good reviews and performances
https://www.amazon.co.uk/gp/product/...2C9C6LXS&psc=1
(good reviews but basic performances I guess)
2) White matte tab tensioned with 1.0 gain as alternative option to potential waves/wrinkles of option one
https://www.luxburgvisual.com/luxbur...ic-105-59.html

Any suggest/comment to help me out?

Thanks!

G.

The Cinegrey 5D claims 1.5 but has been rated closer to 1.0.
Maybe get samples from Hivilux ALR, claim a 1.35 gain:
https://www.hivilux.de/en/Cloth-mate...inema-5D-1-35/

All drop drown screens can potentially have wrinkles, tab tensioned or not. Better quality non tensioned are less likely to have issues then cheaper non tensioned.

Why not get a fixed frame, it's cheaper and it will not develop wrinkles.

I successfully inverted the screen... You have to make sure you have the Auto Keystone setting TURNED OFF.... once you do this, the inverted settings show up. You can turn it back on after you have things set up if desired.

Thanks for the help

@noob00224 Thanks for the link, checking that company too, cool stuff on the website indeed!

Unfortunately, my gf is killing me about the fixed screen idea...that's why roll down/up is probably the best solution

Sooo I tested Cinegrey 5D 1.5 gain but it's way too dark...in the end I have opted for a Duronic fixed 120" screen 1.0 matte white which has great reviews on Amazon and very similar to the Qualgear.

Will mount it tomorrow and will come back with pics/videos

And what about dimming, what figures for dinamic contrast you measure? Native 400:1 or 530:1?

Hi guys,

in the end I opted for an Elite 120" 4K/HDR pull down screen 1.1 gain matte white and I am quite happy with the final result (for £110 on Amazon)

Check pics below:

https://nsa40.casimages.com/img/2020/02/11/200211065141225156.jpg

https://nsa40.casimages.com/img/2020/02/11/20021106522638614.jpg

Contrast & colours improved, blacks still greyish but deeper

Cheers

Hi all,

I used to use logitech harmony to turn on and off HU70LA although the database only have HU85LA, I can still use the basic control. However, since from February, I can't control it via Harmony anymore. Anyone has this experience?

Hi Anthony,

I'm still in the set-up phase and haven't gotten around to using the Harmony with the machine, but I'll get back to you once I try. Do you have any idea what changed? Any updates?

I think all LG remote commands are the same. There is stuff missing for the 85 in the Logitech database for the 85 and I just learned the commands I needed from the Harmony in the bedroom that is set-up for my LG OLED set that is several years old(oddly enough it would not learn the commands directly from the 85’s remote).

Hi Anthony,

I set it up last night using HU70LA as the device identifier in Harmony setup, and it seemed to know that. Didn't have to go via the 85. Maybe the database received an update? Haven't done much with it as I'm away over the weekend, but it turned on and off with the Harmony. Are no commands at all working for you?

I sent email logitech asked them added HU70LA into the database, I received reply from them and said that they have do so.

Now I can found HU70LA in Harmony but the projector still not response.

I never update the LG's firmware, so I believe the problem is on Harmony's side.

Hi all,

My Harmony can control the HU70LA again.

Thank you!

I think all LG remote commands are the same. There is stuff missing for the 85 in the Logitech database for the 85 and I just learned the commands I needed from the Harmony in the bedroom that is set-up for my LG OLED set that is several years old(oddly enough it would not learn the commands directly from the 85’️s remote).

Haven't done much with it as I'm away over the weekend, but it turned on and off with the Harmony. Are no commands at all working for you?

Has anyone else with the HU70LA/LS found that sharpness varies significantly across the screen? I had to send my unit back anyway due to a large piece of debris inside the lens assembly (i mean really large, looks like a piece of string ~10% of the height and width of the image), but I also noticed that when the right half of the screen was adjusted to be sharp, the left third or so was quite blurry (and vice versa). This was immediately noticeable any time text was on screen.

I'm hoping my second copy of the unit does not have that issue, but don't want to get my hopes up. What can I reasonably expect?

Other than that my impression of the projector was quite positive so I'm keeping my fingers crossed.

I don't have any sharpness problem, the sharpness consistent on the whole screen projected from my HU70LA even better than my old HT3550 and HT1075.

Hi, same problem over here, i can't get the image to be evenly sharp across the screen. Correcting one area leads to blurring another one... it's especially noticeable in video games in 4K, but not in movies. In my case anyway the problem is not a deal breaker, just slightly annoying. I might contact LG about it but the idea of sending it back for maybe a few weeks is so depressing
Other than this it's an impressive projector, the image quality is just incredible and the LG Web OS does wonders, eg HDR is working in every video, i also have a Shield and it is just a lottery on that subject.

Glad to hear it! It's working great on my LS, too.

String in the optical path notwithstanding, have you guys made sure you're projecting straight-on? No angles? Mine is getting setup every night until I chose where to install it permanently, and I find that this happens when it's at an almost imperceptibly off angle. Do you use a screen? That'll show even minor distortion from off-angle projection on the borders.

Not saying that that's the reason, just that mine can be fine and slightly out of focus depending on how straight I'm projecting. When I get it right, it's pretty even. There's a limit to these optics, though. Even the best setup will leave a bit of focus difference across the extremes, but it shouldn't be that large.

Hi Liersi, thanks ; mine is perfectly setup - well i hope so - i've made sure that the lens is aligned with the top center of the screen, because i suspected that a misplacement could produce this problem, just like you said.

This is the key word here IMO. I moved the projecter back of forth a few centimeters and played with the zoom lever + focus, and the difference in sharpness uniformity across the screen can vary a lot. How can it be possible ? I've owned quite a few projectors and never experienced that before.
