I logged into the forum just to see if that is what other people are saying about it...

Is the 1500 ANSI lumens including the perceived increase in brightness from laser or LED? Forget which one. 1500 plus the perceived increase should be enough for my needs, but 1500 after would probably nix it for me.

Edit: Found it- "The brightness is based on the perceived brightness equivalent to the brightness of lamp projector". No mention of 3d anyway. I don't think LG are fans.

It says native 4k, but this is the same as all other xpr projectors, while it has all 8.3 million pixels it is not native 4k. But ya, interested in seeing this as it is not a color wheel but a nice RGB setup. Look forward to seeing more info!

I noticed this one says it's a 4 channel led setup. No color wheel to lose color. But no mention of dcp3 coverage. Still interesting as I'm currently in the market. Was also looking at the new Epson 3600/3800 and the BenQ ht3550. So far the BenQ is the only one that covers dcp3 in the literature.

I have the pf1500 and love it but I put it away for my old w1070 cause it's so much clearer. Hopefully they have a good lens on this one

I've asked this before. Manufactures love to boast lumens. Why is LG conservative with their lumens advertisement? Are they simply honest or something?

Are they? That’s good if it can actually do close to 1,500 while looking fairly natural.

Thanks for the info, WindsorTheater.
The specs are a bit weak. Only 1500 LED lumens and no HLG support.

The new JVC and BenQ laser look better.

This thing is probably using the same light engine as the LG PF1500 line uses. 1500 lumens is plenty bright on them, even on medium setting. But, you need light control or don't bother with any projector image looking really good, IMO (why do people do it?)

Nice to see that LG's 30K hour rated LED life is on HIGH, so medium and low settings should offer even longer ratings.

So according to this article it will have 92% coverage of dcp3 and ip control through crestron etc.

Would be interesting to know how close in quality and spec this is to the UST model up. Obviously MUCH less expensive.

any one knows how does this i.e HU70LA compares to the xiaomi 4k or the lg HU80KA one? do they have same dmd? i know the light source is laser vs led and lower lumen one for HU70LA. i would be upgrading from pf1500, so wanted to see if it is really worth upgrading or waiting for real 4k proj, instead of 4k XPR one?

this looks very interesting. Would it output a better picture than my JVC X550R (RS-400) in a pure black room?

If black level is important to you then I would say no....your JVC = 40,000:1 native.


No DLP have ever come close to that, regardless of lamp/light technology. No matter how clever the 'iris' is (mechanical, quick laser dimming, etc..), nothing IMO beats a good honest native black level. The fact that any projector has to "cheat" for better contrast is blah to me.


I'm sure that lumen measurement isn't in a calibrated "best mode" either. Also, ANY 1 chip DLP projector has to be based on sequential color/white rendering, which means it won't be rainbow free, no matter what the technology. I used to get so excited when I read about an LED or laser light based projector, but until you have 3 separate panels (LCOS, LCD, and very expensive 3-chip DLP projectors come to mind), there will always be the chance of the RBE (sorry I keep talking about that, but I'm one of those who are very sensitive to it).



Not trying to be a downer, just giving my honest opinion.

thanks! exactly the answer I was looking for


yes, black level is VERY important to me and I'm also sensitive to the rainbow effect.

Does this one use the small 0.47" DMD or the larger 0.66" DMD (like its UST cousin).

For those looking to this as a home theater option, I hope it's better than the HU80KA. That projector had a color wheel but advertised 2500 lumens. I found the black levels on that projector to be unacceptable for home theater, which was too bad because bright scenes looked good on it. But also, it was not true 4K and the lens itself was not up the the standards of JVC/Epson/Sony/BenQ IMO. It also did not seem as bright as I'd expect for 2500 lumens. Hopefully this projector model is better; the listed contrast is the same but the lower brightness might actually be a good thing in a home theater setting.

It's 4 Channel LED: RGB +(B/G boost). This implementation is supposed to be brighter with better contrast than traditional RGB LED according to the product page:

Unfortunately its 0.47" (XPR), which is why the price is so low...

Both the HU70LA and the HU85LA are both wheel-less single chip DLP projectors. I am extremely sensitive to RBEs and that's why I'm looking a this projector. The HU70LA uses 4 channel LEDs which is why it can achieve 95% of the DCI P3 color space with no RBEs, wider color gamut than Laser. From the LG press release:

"The HU70LA employs an innovative 4-channel LED lighting system and wheel-less technology, to deliver a stunning viewing experience with impeccable color accuracy. LG's wheel-less technology enables each model to produce an expanded color gamut with greater accuracy than traditional Digital Light Processing (DLP) projectors that use color wheels and works to eliminate distracting visual effects such as the rainbow effect, clouding and color distortion. The HU85LA also employs a wheel-less system but uses a 3-channel laser as the light source."

https://www.projectorcentral.com/news_story_2299.htm

this should theoretically result in more sharpness and contrast from the smaller
0.47" DMD as there is no alignment issues as with 3 chip LCD, no color bleed or haze associated with color wheels and phosphors.

Good example of this is the BENQ HT9060... it is a 0,66" DMD which is not native 4K, but when compared to the native Sony 695ES, it can actually be sharper in resolving 4K content because of a better lens and lack of colorbleed /misalignment associated with 3xLCD chips. Check out this comparison by TVS Pro and see what I mean:

https://www.tvspecialists.com/tag/ht9060/

A wheel-less single chip DLP could be even sharper, though only the 85LA has the 0.66" DMD . wish they'd used that DMD for the 70LA instead of the 0.47", I'd pay the premium for the sharpness and better contrast. Still, the JVC LX-UH1B uses the 0.47" DMD for home theater projector and it gets decent brightness, blacks and resolution even with a color wheel. See this comparison against the 5040UB and UHD65:

Doesn't this LG compete directly with the latest JVC entry 4K laser. The JVC is $3,700+ and the LG is $1,700. Aside from LED isn't as bright as laser what is missing from the LG compared to the JVC for more than twice the price?

I didn't know that JVC has a sub 4k entry level laser, that's awesome! Which model JVC projector are you referring to?

Without knowing any of the details, I can guess that the JVC will probably have a dynamic Iris like the JVC LX-UH1m and much better lens/placement flexibility, which could account for the cost difference. LED light engine might also be cheaper than Laser.

The LX-NZ3 seems to use the same lens assembly as the LX-UH1 but according to JVC uses dynamic laser dimming rather than an iris.

I need an upgrade from my PF85u - which has lasted quite a few years now, hopefully better than the laser projector version

- input lag in the 30ms range or less at least at some resolution if not at faux 4k
- 120hz at 1080p
- Black level at least as good as the pf85u, hopefully better
- Quiet fan
- low wattage like the pf85u
- better lens with corner to corner sharpness

Looks like it the JVC has better placement flexibility than the LG HU70LA, but I’d say the color will be better on the LG because it’s wheel-less, 4RGB LED and less bright.

LX-NZ3 doesnt claim any DCI P3 coverage, and the body is identical to the LX-UH1 so my assumption, it’s identical except for the light source - and that laser dimmer tech, which they imply is faster than a mechanical iris. Can’t find anything about a color wheel, but if it didn’t have one, they probably be bragging about it... At that brightness they are probably going for entertainment segment anyway.

JVC doesn’t want to actually encroach on their own higher models with sharpness and contrast, so they stay away from 0.66” DMD for their low end segment.

how does HU70LA compares to the xiaomi 4k or the lg HU80KA? also the avsforums page says price is 1599, while the first post here says 1799? which one is it, do we know?

LED projectors do not have color wheels.

Yes, that's what I said above... but I tried to find information on the laser based JVC LX-NZ 3color wheel, as laser light engines can use them, but couldn't find it. please post if you can!
