If it's 0.47, it's competitor will be Benq and JVC which is less expensive and lighter than HU80KA. Hope it's 0.66 too, otherwise will have to turn around and look for something else.
I've been following those other projectors too. The problem seems to be that many other faux-K projectors don't support user firmware updates. Neither the Acer nor the Optoma that I cited do. Since 4K is still in flux, there appear to be a myriad of patches from the various (DLP) companies. A year from now it won't be an issue, but it appears to be an issue right now.

Since the manual mentions that the HU80KA supports "software updates", I'm guessing that means the same thing as "firmware updates".

If the HU80KA is truely a 0.47 projector, then the decision for me, it is "0.47 + user updates" vs. "0.66 + ship somewhere for a service updates". That is why I listed the 3 projectors that I am considering.


I've been a DLP user since 1999. My present Panansonic 8000 is my only diversion into 3-panel LCDs. I'm eager to go back to DLP.

Thanks,

Scott

Just heard from a reliable source the LG HU80KA is using the 0.47 chip.

Right now the Optoma UHZ65 has my attention. I’ve been out of the projector game for a long time and don’t know if I should wait for the next best thing in this price range.

Based on other threads, a 0.66 chip is noticeably better than a 0.47 chip. But you have decide if your viewing distance is close enough to see the difference.



See 3DBob's post # 438 on this thread:

https://www.avsforum.com/forum/68-dig...l#post55936722



For me, I'm deciding between the LG HU80KA, the Acer VL7860, and the Optoma UHZ65. Of the 3, I want the HU80KA and really want it to have 0.66 chips. I'll have to wait for someone to definitely say 0.66, but so far the HU80KS (European) manual says 0.47. After that, I have to decide if my 124" screen at 15 feet is enough to see the added detail or not.



The graph in post # 5772 on this thread say "maybe":

https://www.avsforum.com/forum/24-dig...l#post56106768







I'm in the market for a new projector anyway since my Panasonic 8000 is misbehaving and I'm eager to return to DLP technology and replace bulbs with a laser.



Hope this helps...



Scott


You mention the Acer VL7860 as one of your options. I see it as restricted distribution (at least in the states)

The Acer VL7860 and the Optoma UHZ65 use the 0.66 chips and are laser-based.

At least the HU80K* is laser based, but things seem to be pointing to it using a 0.47 chip But we'll have to wait for a confirmation. So far, I've only seen it quoted as 0.47 in the European version of the manual (HU80KS), and that entry is missing from the HU80KA manual.

For all of you thinking about the VL7860,make sure you get it with the latest firmware.If not, you're looking at your first service call off the bat. I came close to pulling the trigger on this a month ago but nobody could confirm the current firmware on the VL7860.

from the youtube comparison video , the native 4k is much better than xpr. so 0.66 should be much better than 0.47 since it's double the pixels.
I have PF1500 which is also firmware upgradable. But i never see an upgrade since purchase.

It is not double the "pixels", they both put all 8.3M pixels on the screen, unlike the Epson and JVC LCoS models that only put 4.15M pixels on screen. The 0.47 DMD only uses 2.1M mirrors to produce the 8.3M pixels compared to the 0.66 DMD which uses 4.15M mirrors to produce 8.3M pixels. It may sound like semantics, but it really isn't. The resolution of all the DLP 4k projectors thus far is the same -- the full 8.3M -- while the non-DLP "fauxK" projectors are only producing 4.3M.

I would not expect great contrast from this LG, but I would expect it to be better than the lamp-based 0.47 projectors have shown. If LG has done a good job with its lasers -- on/off contrast could theoretically be infinite, right ? Based on how far below their ratings LG LED projector brightness have fallen, it is the brightness for HDR I would worry more about.

sorry. i mean mirrors. Of course they are all 4k pixels. but 0.66 is double mirrors compare with 0.47.

Post # 29 has the link to 3DBob's comparison of 0.66 vs. 0.47

The close-up view shows a definite difference. The question is if folks will see that at their viewing distance and screen size.

I think this ticks all the boxes. Shame its 2.8K euro but I can't blame them if it performs similarly to other projectors in that price range. Hopefully it's quite silent!

"XPR pixel-shift technology combines image processing with the ability of the DMD's four million mirrors to shift at the microsecond level to allow each mirror to create two pixels per frame, creating a UHD 4K image from an otherwise native 1080p chip."
does this means hu80ka using 0.66 chip?

It’s using the 0.47 chip. (U.S.). Reliable source has a demo unit.

Who has this demo unit, and why haven't they reviewed it?

Projector Central has a nice commentary on 4K vs. faux-K. Like us, they recognized that actually seeing 4K or faux-K pixels from a normal viewing distance is difficult. They then observed that the contrast becomes the dominant feature (black level, HDR, etc.)
http://www.projectorcentral.com/4k-p...rs-defined.htm
For me, this points towards a laser system with HDR like the HU80KA as opposed to a lamp.

I was at Fry's in Fremont (California) a few days ago and saw the large LG OLED 4K flat panels back in the darkened back corner. The pictures were stunning. Even inches away from the screen I had trouble seeing the pixels. But what made the picture stunning was the contrast. The blacks were black and the colors were bright.

So let's hope that the HU80KA HDR works better (trouble free) than other new faux-K projectors'

Need make a decision. Now the uhz65 is $300 cheaper than hu80ka in Canada, since have to pay duty and tax. Which one to get? I really like hu80ka for the mobility. But don't know how much better 0.66 than 0.47.

There is a previous discussion here about 0.47 vs. 0.66 (see the last several posts). There is also more details in this other thread:

https://www.avsforum.com/forum/68-dig...l#post56212334

The 0.66 chips do produce better/smaller/sharper pixels than the 0.47. The issue is if users will see this at typical viewing distances.

The conclusion from this:

http://www.projectorcentral.com/4k-p...htm?page=Intro

is that black level becomes a more dominant feature.

It is unclear why there aren't any USA reviews yet. I've been watching Projector Central waiting for theirs. Their previous comment indicated that they should have had an HU80KA for several weeks now.

I'm looking at the UHZ65 also. There are 3 issues I'm tracking before I make a decision about which projector to buy:
  • black level
  • 0.47 vs 0.66
  • user firmware updates (instead of shipping it back)

Since 4K HDR is still in-flux, this last point seems to be very important; and certainly is to me. I'm not willing to ship a projector back (risk of damage in shipment) for something as simple as a firmware update. The various other faux-K threads are filled with firmware issues (Viewsonic px727, Acer VL7860, Vivitek HK2288, BenQ HT2550, Optoma UHZ65).

The HU80KA appears to be one projector that has user-upgradable firmware. Due to the laser, black level should be "good". And 0.47 vs. 0.66 may or may not be an issue depending on my screen size and viewing distance (see previous posts and graph in this thread).

same boat. I don't think i can notice the difference of pixels. but contrast and brightness is more concern.
hope there is a side by side comparison. BTW, i doubt lg will upgrade the firmware even it's online upgradable since i didn't see any update on my pf1500.
