How is it off topic to your question? You questioned the lumen loss? I was showing that Chris got about the same lumen output with smartco engaged as Ruined reported.

Yes, the lumen loss as compared to normal mode where he said is supposed to be 20-25% less in SmartEco Mode!, which was NOT the case.

Nobody was questioning his SmartEco number. What was in question was whether SmartEco was 20-25% less than the Normal Mode using just Automatic Power Control.

Normal Mode = 212.614 nits
SmartEco Mode = 213.8895 nits

Read the flow I posted above.

I am taking Friday OFF to do some extensive comparisons ....will have some more substantial feedback after then.

@woofer , appreciate your efforts ,I sort of know what to expect , looking forward to your feedback none the less . This projector is the ONLY affordable option to the VW5000 for super large screen and adequate HDR, in fact this one can do both . All of the rest available, the flagship options can barely manage 30FL on a 140" scope screen , even then it will need to run on maximum, require higher screen gain materials, anamorphic lens and mounting at the shortest end of the range .



I was told that Robert Silva, the THX standards guru, has a setup that yields 400nits(116FL) , that says everything right there, after all, this is the guy that stated contrast was number one years ago. HDR has changed everything, more brightness is required , for most manufactures it now the weak link in this chain . For HDR the current minimum of 30FL is just not enough , 50FL is where HDR starts to come to life, better from there on . This projector has many characteristics equal or better than many of the current flagship projectors , brightness is in a different league however ,at the price point there really is no rival .



This projector really needs a high contrast grey screen IMHO, it certainly has the additional lumens to allow this without sacrificing too much .

But what affordable projector has 5000+lumens, 4k , excellent lens with excellent clarity and sharpness and being a Laser! I can personally live with not the best black level in very low APL scenes.
If i was paying 20-30k+ i would want it to have everything, heck the 300-400k barco thor has around 6000:1 contrast after modding and is considered probably the best in the world ( until christie releasss their new PJ ) yet some people would say its unwatchable to them because of that.
I bought mine without seeing it cause i trust Dave and he was right, but people should try and see it like Woofer's friend who liked its performance and not just read the specs and dismiss it.

Exactly... In fact i like watching SDR in far higher than 16fL... and HDR in as high as possible until it reaches a point where i can no longer tolerate it..
I m only using ecomode when using MadVR excellent dynamic tone mapping which is very bright indeed, with normal mode some bright scenes are very very bright but boy what a sight.
In eco mode i m getting around 160-170nits and with some settings in Madvr u can make it as bright as normal in bright scenes and as dark as eco in dark scenes, so kind of like smareco lol.

Going by Chris's numbers above, the normal mode brightness and smartco, both are around 1,250 lumens. Chris was close to minimum throw for his 92" screen so that is very close to max calibrated brightness. 1,250 is a lot of loss for a 2,200 lumen manufacturer spec. I agree with you that it does not look like smartco costs you any lumens. The projector is not as bright as I thought it was.

Want to clarify, talking about 9060, not LK970. Don't want a potential LK970 owner reading this as LK970 numbers.

Roxiedog, this unit thrives with HDR material. The low apl performance is not great, (below 1%)but everything else is excellent. If you are not RBE sensitive it makes sense to at least take a look and see if it works for you. Also works well with a gray screen I tested some samples from Severtson that worked well with the unit.

This PJ IS interesting...

To be blunt, no ways around it...its LOW APL performance is POOR!!! BUT...... on the majority of other material i really does look stunning.

On "Black Panther" the DARK car chase/street scenes look VERY "Ordinary" , but on the scenes with the fight near the waterfall its just "Gorgeous" On this particular scene i prefer the image from the LK970 to my own Z1/ RS4500!

Having such shear brightness for HDR really does help.

Very nice... so, now we know where scenes starts to look 'normal', where it breaks down a little and where it shines...

From your review, I can already tell that the Sony 760ES will be superior to this projector with scenes like the black car chase in Korea town.. because that scene was so addictively good for me that i re-watched it a dozen times... that was one of my fav scenes so far.. i am loving all scenes like that on that projector...

Where the 760 breaks down is the initial black panther forest fight scene.. that scene seems too dark to see much of anything in many circumstances.. other than that scene the projector was really good.. I am sure any scene brighter than the Waterfall scene, the BenQ will take over...

I hope i can somehow get to see this projector.. would love to see how 'high lumens' like that with HDR content.

Roxie, very interesting to hear more and more people like higher lumens for HDR...

I hope more calibrators jump on board...

I will have to check the Black Panther scene out then. I don’t have that disc yet. The low APL scenes I’ve tried (raccoon in forrest killing pirates in GotG2) all looked amazing to me. Maybe some settings need tweaked?

You never answered. Was this with HDR, my settings, etc.?

After 4months i m still finding some tweaks to improve it.

and if u consider the price this unit can be had for, its an amazing value.
Hi Tnaik, I currently have a RS440 and I am looking to move to the LK990 I was wondering if you noticed much difference in input lag in gaming going from the RS440 to LK970? One of the things that bugs me with the JVC is the long sync times, how are these with the LK? Also which specific movies do you still use the RS440 for? I wont have the ability to keep the JVC so just wondering what I'll be missing.

Thanks in advance

Scott

Hi everyone,

I am very impressed by your posts on the Benq LK970/990 projector. I currently have a sony vw285es, which is just able to display SDR on my 150" screen. I would like to upgrade to a true HDR capable projector.

So I am wondering where you bought your Benq (I'm in the U.S.), and, if it is possible, can you please share the price you got through PM?

I tried to sent PM to some of you, but I was informed by the system that "To be able to send PMs your post count must be 15 or greater."

Thank you a lot in advance!

In HDR mode, the 285 will not be able to do a 150 inch screen any justice... I think Dave Harper can help you with the BenQ... he also have an excellent experience in calibrating it..

Yea, but this benefits the many others sick of the same rhetoric, I'd call this a win win.

Outside the VW5000 and the LK 970/990 nothing else will be sufficient on a 150" screen, I was trying to make the same thing happen , even with a lot of help it was still going to be weak for HDR. Either stick with a much smaller screen 130" or less and add a lot of gain or go with a projector with the ability to do it properly accept the areas a little weaker . The closest projector that can do it all is the new Christi , apparently it's a tad over the budget for most .

I’m not a dealer but I can help find one I guess. I got good deals going direct to BenQ actually, which is why I haven’t used a dealer for one in awhile.

I have my LK970/anamorphic lens combo available here in Dealer’s section of the Classifieds, so I can’t move onto the LK990 for testing until that’s sold.

The unit definitely struggles with low apl performance. Especially all black scenes with minimal highlights. I really wish BenQ would hire a dynamic dimming guru to program the algorithm for the low end. Then the unit would give the best performance possible given the technology limits of the single chip dlp. An manual iris and internal color filter would be on the wishlist too while I am at it. One interesting thing, that I thought I would share was while measuring 100% white pattern the unit pulled only 70% power draw. On certain scenes of infinity wars, it maxes out at 100%. So even measuring 3600 calibrated lumens on the white pattern, there is still excess brightness in reserve for actual content. The algorithm rarely ventures below 50% draw on the low side however. I wish it was more aggressive especially below 1% apl; those are essentially all black scenes anyway.

On "Black Panther" the DARK car chase/street scenes look VERY "Ordinary" , but on the scenes with the fight near the waterfall its just "Gorgeous" On this particular scene i prefer the image from the LK970 to my own Z1/ RS4500!

Having such shear brightness for HDR really does help.

Yes its not the best in very low APL scenes and thats why i kept my rs440 for those specific movies, but everything else is excellent!!

After 4months i m still finding some tweaks to improve it.

and if u consider the price this unit can be had for, its an amazing value.
Hi Tnaik, I currently have a RS440 and I am looking to move to the LK990 I was wondering if you noticed much difference in input lag in gaming going from the RS440 to LK970? One of the things that bugs me with the JVC is the long sync times, how are these with the LK? Also which specific movies do you still use the RS440 for? I wont have the ability to keep the JVC so just wondering what I'll be missing.

Thanks in advance

Scott
Lag time is identical to RS440 in low input mode, if u are a gamer, it is a no contest, the LK brightness/pop/sharpness make games look like ur playing on a huge monitor, it is that sharp and accross the screen.
Mostly dark movies, like Overlord for example which has many dark scenes, i guess the harry potter series also since i hear its pretty dark but didnt watch it yet, usually 3 out of 10 movies i watch on the RS440.
Yesterday i watched the newly released 4k HDR Mortal Engine on the Lk970 and this movie is like its made to be played on the BenQ, sharpness out of this world and image/color pop like crazy.

EDIT: sorrt forgot to answer about the sync times, its pretty fast changing from presets or from source to source, i would time it when i m home but probably around 5sec.

I had to scrap my 73" Mits crt rptv years ago when the green crt tube began leaking glycol coolant onto a high voltage circuit board.

How long was this running before it leaked? What do you think is more likely? A liquid cooling leak? Or a fan bearings wearing out and it becoming very noisy and needing replaced?

Yep, with madVR dynamic tone mapping, you could be back into the SDR range for your HDR and it still looks fantastic.

Liquid cooling has been around for a long time in projectors. My Sim2 MICO 50 had liquid cooling back in 2009, and I bet it wasn’t the first one.

I would talk to Dave Harper. He knows this machine inside-out and also does calibration.

Agreed. The things MadVR can do are amazing. It singlehandedly extended the life of my Sony 1100 at least a few more years.

I am now using a Panasonic UB820 to convert HDR to SDR, combining with some tweaks of custom color temp on the projector (which gives me ~27 FL, 92 nits) to play my UHD HDR movies, which gives me an acceptable image quality.

Before using the UB820, I mainly used an Oppo 203 to output HDR contents. I was using my own custom gamma curve (similar to the german curves, but more aggressive) combining the tweaks on the projector to get an OK image quality. I also tried some high gain and ALR screens, but didn't like them due to the hot spot issue.

With my current setup, UB820 does the tone mapping and outputs everything in SDR format, with the peak brightness being 92 nits. So I am definitely looking for more brightness, much more! I was considering VW5000, but its price makes me hesitant. RS4500 is much cheaper (still expensive though), but its brightness is still far from being adequate. I do like high contrast, I love my OLED TVs, but high contrast with low brightness (~100 nits) is like a car with good handling but only 100 horse power.

It looks like the benq could be a reasonable alternative, the only problem is I don't know from where I can get quotes. It would be great if you can help me find a dealer.
