Any hope for Viewsonic LS700-4k?

Hey guys,

I've been eagerly awaiting the LS700-4k as it seemed like the only upcoming answer to the HT3550, which didn't impress. The only recent blurb I've been able to find is that it was at infocomm 2019...do we know anything about it's release? Is anyone expecting it to be a winner around here, or am I just hoping for something that isn't real.

I was super excited about it when it was announced. Since that it's just been delay after delay. My hype just died.

At this point I would not be surprised if it is cancelled.

I thought this was the one that was supposedly going to be super low lag because of it’s laser light engine?

What to do if you find yourself stuck with no hope of rescue:
Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems to be more likely, consider yourself lucky that it won't be troubling you much longer...

Someone emailed them about the projector and they said that the spec that was printed was a typo and they were fixing that the actual input lag was 100 millisecond

68ms slower than my TN

I don't have a high enough post count to link to the other thread, so I'll paste my message from there to here:

tldr: approx 68ms slower than a Viewsonic VX2433wm (TN) at 1080p60 (i.e. 4 frames)

I ran the test two ways and got the same results. I'll describe the more obviously fair way. My desktop PC is hooked up to my Onkyo receiver. There are two HDMI outputs from the receiver. One is hooked up to the LS700-4K and the other to my Viewsonic VX2433wm (TN). I displayed a webpage with a bit of javascript to constantly display the number of milliseconds since the page loaded in cells of a table. The difference in timestamps between adjacent cells was 3-4 milliseconds, so depending on the exposure timing, you could see about 5 cells transitioning simultaneously. The crisp pictures consistently showed a 68ms difference between LS700-4K and the VX2433wm. At 60fps, that's 4 frames. In pictures that included two frames (my exposures were 1/80 of a second), it looked like the difference in lag might be as little as 48ms.

LS700-4k is on it way!


I received a notice from projector people that my LS700-4K has shipped. Expected to arrive Tuesday 1/14/20. I'm super excited and honestly did not believe it would ship anytime soon. I was honestly thinking of purchasing an UST projector because this was delayed so long and there are very few 4k short throw projectors that will work for my room.

I currently have a Sony 40es so I'll be comparing the two. I have zero experience reviewing projectors but i'll give my honest opinion.

I can't wait to hear what you think. I'm shopping around and stalling buying anything because of the potential of this thing. Let us know how it looks!

Also, the passioncinema review of the 1080P version states it's out of box color accuracy was bad and it took long hours of calibration to bring out the full potential of this projector.

I was hoping this would be a viable option since I am coming from a Benq LK952 but it appears this would be a lateral move at best.

Is the light border a big deal if the screen has a black frame boarder? For me i don't think this will be a big deal, but i can see it being a problem for screens without the black frame to hide the "light border".



My big concern (and I'm just realizing this) is the LS-HD is a laser projector. I was under the impression it was a lamp based projector and that by going to the 4k model i would be getting an improvement in black level (seeing that laser projectors seem to have a natural advantage in blacks over their lamp based competitors).



I'm confident the sharpness and brightness will be an improvement over my Sony 40es, however my main concern is the black levels.

Color accuracy is another concern, however if i have to spend some time dialing in the colors, I'm ok as long as the end product is perceived to be on par or better than my sony.

I highly doubt it will reach the HW40es's black level. Only the HT5550 (DLP in this price range) gets close, and that is with an active iris.
Is the room treated for reflections?

The light border is not a problem if the screen has a black border. The black border can be enhanced with black velvet if it's really necessary, but usually the black border of a screen or of a felt tape is enough.

Looking forward to seeing some impressions. I’ve soured on the 3550 due to all of the issues folks are having with it.

So in one of my crazier moments I went ahead and ordered this AND the other projector I was eyeing. I couldn't buy the lg knowing this might be better for the same cost, nor could I buy the lg knowing this may be terrible. Both with fair return policies. May the best projector win.

The Ls4k is here! Arrived a day late but its all good


I spent about an hour tinkering once installed. The installation isn't perfect. Currently I'm using a 92'' screen but i bought this projector mainly to use with a 110 or 120 inch screen which i have yet to purchase. The image is extended beyond the screen frame by about 3 inches on all sides due to my poor initial install. I can probably readjust but i wont bother as i'll be getting a bigger screen soon.


Initial Impressions: Huge improvement in brightness, sharpness and color! 1080p content appears crystal clear and this appears to be a big improvement over my Sony with 1 or 2 glaring issues. The biggest issue is the lens uniformity is terrible. This is my 4th home theater projector (in 13 years) and i don't ever remember not being able to focus the image on previous projectors. If I focus the center of the image, the corners tend to be blurred. Sometimes it seems unnoticeable and other times it's terrible. I'm hoping this is just a manufactures defect. I also question weather this could be an issue with projector being zoomed out all the way despite the image being bigger than my screen?

Color accuracy seems off but its hard to tell where to start as sometimes blues appear to pop out of the screen and other times reds do the same. I think i would get used to the extra saturated colors but not when it comes to unnatural skin tones (work in progress). BTW color accuracy appeared much better in Movie mode however i felt it muted the colors too much and also reduced brightness more than I'd prefer. Currently I've settled on Standard mode but its a work in progress.


So far I really like the improvement in picture quality (minus the focus issue). I'll be looking to swap this out with another one if i cant get the focus issue resolved.



Btw i love how this turns on so quickly! Also, its definitely louder than my Sony, but it doesn't bother me. Its sitting right above my seat abut 4 feet over my head.


I'm looking forward to testing Sports, 3D and 4k content soon. I'll continue to share my opinion as i test it out going forward.

Mine just came in. I've only just set it up, thrown it on a wall and started tinkering with settings but my initial impressions are quite negative. I have a new LG HU80KS that is my frame of reference and I'll be doing some side by side comparisons to see which is going back. But 15 minutes into this I almost can't fathom it not being the viewsonic. Will update more later as I toy with settings and compare side by side, plus see how they look after the sun sets as there's some indirect natural light. Sadly I donated my old screen and my new screen is on the way, so full picture compares will be against a white wall and also against a plethora of 8.5x11" screen samples from everyone in every color/alr/gain, but it's hard to judge a projector at that scale.

I spent some more time with the Ls 700-4k. I did some A/B comparisons with my Sony 40ES. Screen is a 92’’ Elite screen Acoustic Pro P3. Haven’t had much free time unfortunately so no pictures at the moment.

I’m really torn about the overall picture quality. The picture in bright scenes is crystal clear, colors are vibrant and pop off the screen like nothing I’ve ever seen. The color accuracy is an issue but I made some minor changes and found the color accuracy acceptable. My biggest issue is the black level/shadow detail. There were scenes on the Sony which showed shadow details with minimal issues. The Viewsonic on the other hand is pretty bad in this regard. Shadow details in many cases look nonexistent. I tried to bump up brightness/contrast to see if I could match the Sony’s shadow details, it’s still not nearly enough. Plus with the added brightness the picture quality suffers.

My projector placement is very limited which is why I purchased the Viewsonic. At this point I’m thinking about buying a Benq Ht3550 to see how the blacks compare. My goal is to buy a 110’’ screen but at this point I either have to stick with the 92” to keep most projector options open, or go with the Ht3550 as there are very few short throw projectors that will throw a 110’’ screen in my room. Third option is an UST projector.

So i decided to return the Ls700-4k. In my opinion, It just doesn't seem to be designed for home theater use. The shadow detail is non existent. The only way to see any shadow detail is to pump the brightness to crazy levels causing the picture to be extremely washed out and even then, the shadow details are terrible. The colors are way off too. I'm so conflicted on how to review this projector. I did not try 4k content or 3d content. There wasn't a good reason to test those formats knowing that I wasn't happy with the projector.





Pros:
  • The colors are vibrant and head and shoulders more colorful than any other projector i've ever seen.
  • Picture clarity/sharpness is amazing!
Cons
  • Black level and shadow details are horrendous. The picture looks washed out in dark and even semi- dark scenes
  • color accuracy was difficult to calibrate.

Sad to hear. Still awaiting other reviews...maybe the unit was defective. Would like to upgrade my 45ES with bright laser..

AFAIK it wasn't designed for home theater use.

I'd rather focus my attention on the ViewSonic X100-4K, which supposedly should finally see a release this Spring.

Here is its data sheet: https://www.viewsonic.com/us/catalog...y/x100-4k.html

Hey guys, we just posted our review of the LS700-4K at ProjectorCentral (link below). Our conclusion was the same: not really made for home theater even though it is pitched for both HT and business. And though it was okay (if a little dim) with SDR in its best Movie color mode (post calibration), we never got it looking quite right with 4K HDR content with any settings. Could be a decent option for more casual ambient-light viewing, though, you might be better off with the LS700HD 1080p version for that.

Thanks for the review! Too bad, I was really looking forward to this pj for what? Over a year now? Anyways, this is all I needed to read to instantly drop this from my list of potential pj's: "...the projector's 3D images were very dark and afflicted with ghosting, and I found them uncomfortable to watch."

So it doesn't even seem to have the usual 3d benefit of DLP's. That being the extremely low ghosting...

womp womp. Well, thanks for the review; looking forward to hearing if the X100-4k is any good.

Yes, we're excited for the X100-4K as well, which we saw at CES. Looks like it's being targeted more directly at the home theater market, and unusual in offering an LED light source (2,900 LED lumens, 1,200 ANSI lumens) vs lamp or laser.

Viewsonic's spec sheet states 2900 ANSI lumens.

Yes, thanks for pointing that out. Not what I was quoted at the show, and I'd be surprised to find that's the case since aside from the Philips HLD technology (which is not being employed here) I'm not sure any traditional LED engine gets that bright. But for now I'll take them at their word.

Viewsonic just updated their X100-4k datasheet and it now states 2900 LED Lumens:

This implies about 900-1400 calibrated ANSI Lumens.

Thanks. I saw the ViewSonic team at ISE in Amsterdam on Wednesday and pointed out the error on their website; nice to see they corrected it quickly. Per your calculation, they told me they expect the ANSI lumen spec to be 1200 to 1300 lumens; they multiply ANSI by about 2.4 to get their LED lumen number.
