Benq LK952 - 4k laser, 5000 lumens

I don't see any dedicated thread here discussing this projector - only few mentions in 970/990 threads.

https://business-display.benq.com/en...ors/lk952.html

Only difference I was able to see between LK970 and this one - is DLP chip size - it uses .47" 4k chip instead of .67" 4k
Other specs pretty much the same - 4k/5000 ANSI lumens, no 3D.

For given price (below 4k$) it looks as very attractive option and brighter alternative to optoma ohz65 - unless it have some known problems.

Anybody has any experience with it?

glad to see this one up there now. We certainly need to know more about it as it peaked my curiousity:

(ie I'd like to know if it has shares the same lens as the W5700/HT5550 as their throws and lens shift match exact.
What Colour wheel type/segments, etc)

FYI for Aussie readers, this one is apparently RRP $6999.

Isn't it because this projector is targeted for business and installation purposes rather than home theater?

But, are they good as HT projectors? Or is there a different reason why they are of interest here? Is it because they’re laser projectors?

I have this projector currently in my basement. We've had it for 3 months and will be returning it because they can't fix a 2 inch light bleed over the picture area that's pretty annoying. We have had them replace it twice with the same issue. I'm guessing because it's meant for business this isn't an issue for most. I have pictures in case your interested.

for me - because of lumens. I do use projector in large living room - and at daily time there is some ambient light present.
With current prices - 4k$, 5k and 7k (952, 970, 990) - it looks like decent value for 4k hdr + lumens + laser.

is that USD in terms of pricing? seems super good value especially the 990.

The lumens in this projector makes it very interesting to me. How is it in terms of picture quality (colors, contrast)?

Yes, please post pictures. I'm interested in the LK952 since HDR needs higher brightness projectors. Since it is personal taste, photos of the light bleed would be helpful.

Thanks,

Here are some pictures of the projector. The light bleed doesn't show up in pictures that much so that's why I had to use slower shutter speeds on a few picks so you can see it, the others are just natural.

Overall, I think the projector looks great with HDR 4K content. I haven't gotten it calibrated yet because we were having this issue so the colors aren't perfect but overall if it wasn't for this issue, we would be keeping this.

Isn't that the light border (pond of mirrors) common to the 1st gen DLP 4K 0.47" chip?

The LK952 uses the 0.47" DC3 DMD DLP

According to the LK952 manual:
https://business-display.benq.com/en...downloads.html

I'm not sure which chip is actually in the LK952, but here are the two that I could find:
http://www.ti.com/product/DLP470TE
http://www.ti.com/product/DLP470TP

The price difference between the two on the TI web page (http://www.ti.com/general/docs/lit/g...A&fileType=pdf) is $178 vs. $227; while the 0.66" chip is $495.


Interestingly, Figure 6 (attached) from here (http://www.ti.com/general/docs/lit/g...5&fileType=pdf) indicates that a high-brightness projector is indeed important. So in that case, the borders may be less of an issue since projectors such as the LK952 are specifically for bright environments while projectors such as the HT9060 are for darker environments.

Mikero, did you end pulling the trigger on the LK952? Interested in your impressions.

Also @sacwooky when you had the LK952, did you notice whether it supported HDMI CEC? It's noticeably absent from the user manual (but is in the manual for other BenQ projectors).

Thanks!

Edit: The BenQ pages are searchable again for the LK952. So I've edited my comments here...

https://www.benqb2b.com

https://www.benqdirect.com/
Although it is still listing on the info pages:
https://business-display.benq.com/en...ors/lk952.html

https://www.benqb2b.com/lk952-hdr-la...ith-5000-lumen
I was leaning towards this LK952 because of its smaller size and reasonable price. My light control isn't very good, so I wouldn't benefit from an HT9060. The LK series is more appropriate for me, and I like the smaller size of the LK952 as opposed to the much larger/heaver LK990.


On the BenQ pages, here are the two part numbers:
SKU-LK952-001 NEW https://www.benqdirect.com/lk952-hdr...ee=29&fep=1523
SKU-LK952-002 REFURBISHED https://www.benqb2b.com/lk952-hdr-la...0-lumen-refurb


Thanks,

Scott

Hello aeneas01. You've had your BenQ LK952 for a couple of months now. Any thoughts?

Thanks,

Scott

They use a 1080p DMD for the smaller XPR based machines. But the light engine is setup for the larger chip size, so there is a gap. I've talked to other vendors about this issue and they confirmed. So the light spill is because of the smaller chip size.

I find it interesting that you left out the highlight of not recommended for home theater use. Reading that review it is clear that they are talking about this in a classroom environment.

I find it interesting that you would say that. Here's what the review actually says:

Quote:
This LK953ST, though a business and education projector, could be a “cross-over” projector as well – meaning it is also suitable for home use. Though neither Art or I would choose this over a dedicated home theater projector for movie viewing, its excellent color and respectable black levels would make this projector a great one for a media room, for watching sports and TV, even with a healthy amount of ambient light present.

Yes, I just received my BenQ LK952 from Projector People. I had been considering these 0.66" units:
Optoma UHZ65
Optoma ZK507
BenQ HT9060
Acer VL7860
BenQ LK990
but decided to get the BenQ LK952 (0.47" chip) just because of price and 5000 lumens.

We've had the LK952 for a week now and are happy with it and it is a dramatic step-up from our previous Panasonic 8000 3LCD projector. I have too many windows to benefit from inky black levels, so this projector is better suited to my living room.


I ran my Spears & Munch UHD 4K disk on it, and things look OK to me with all of the default settings. I haven't made any adjustments yet (I don't have any color filters...)

I have firmware 1.0.1 and am running in sRGB mode and Normal brightness; but I do have Dynamic Dimming turned on (it isn't listed in the V 1.00 manual). I haven't A/B it yet to see if the difference is noticeable. My Passengers 4K disk arrives tomorrow so that will be a good test...


I have attached 3 photos:
  1. the projector mounted to the ceiling. This is the same universal mount that I had with my Pana8000, and the change-over was trivial. I like the LK952 center-of-mass mark. The tapestry is there to deaden the sound back-reflection and to hide the cables. Its been there for 20 years since my original Sharp Notevision7 projector.
  2. the image on the screen with 2 of 3 of my the black-out blinds down. Stewart Filmscreen GrayHawk. Sized for 4x3 from a couple of decades ago before 16:9.
  3. the image on the screen with NONE of my the black-out blinds down

My windows face west, but it is still morning so this is light through the window (not direct sunlight).

The 3rd photo is poor just because of the camera -- the image on the screen looks fine and colors are OK. This is the benefit of 5000 lumens! My former Panasonic 8000 3LCD projector was completely washed out in this case.

Thanks for the response, glad you are happy with it. I ended up going with the optoma zk507, came in a few days ago. I’ll post first impressions and some pics in the next week or so after my SI slate .8 screen gets installed.
