That's very disapointing. The initial release date was february IICR.

Does Projector Central have inaccurate info on their website? They appear to list it as in stock and shipping. I didn’t call them so perhaps a problem arose and site is not updated?

The LS700-4K seems pretty enticing to me. Is the lack of buzz compared to a couple other new projectors just due to the apparent lack of review units out there?

no lack of buzz, but some of the bigger companies spam these forums with their views. Viewsonic in my opinion has not done that, hence, not much info.

I believe so. I'll call again today.

I saw they listed it as in stock and called, and they said it was a mistake. The person looked up and saw they had a few backorders that were listed to be shipping June 24th...hopefully that will be the case.

I was told early July when I asked via online chat feature. Might continue to push out further depending on number of back orders.

I've been monitoring for an online manual to be posted or early review but nothing on the LS400-4K so far. I guess they don't have early engineering/production evaluation units out for reviews like some other companies?

Yeah, it's weird. At this time we should have reviewers receiving units and talking about it, but it look like there's zero buzz around this projector. Maybe ViewSonic is not much confident about it's quality, or this is just the way they usually handle marketing.

A little bit of more info from ProjectorCentral.com

"While laser seems to be rapidly taking over the commercial projector space, its trickle down into the home theater arena has been, to date, even less than a trickle. Sporadic models have appeared at typically premium price points, but budget projectors with a laser engine have been largely absent from the landscape. That's starting to change. With the new LS700-4K, ViewSonic offers up a tidy home theater projector that doubles easily as a small business projector and delivers both 3840x2160 UHD resolution and a 20,000-hour laser light source, all for the low street price of $2,199. (A similar 1080p version, the LS700HD, is available for $1,399!) The basics are all here: a 3,300 ANSI lumen brightness spec, 3 million:1 dynamic contrast rating, HDR10 compatibility, ViewSonic's SuperColor technology (which relies on color wheel design and dynamic lamp control to optimize color brightness and gamut). There's a switchable Rec.709 filter that allows users to adjust for higher brightness for business use or wider gamut for home theater content. Motion interpolation is on board, and gamers will appreciate the fast 16ms lag time. There's a modest (but useful) 1.3x optical zoom that provides a throw range of 4.9 to 28.8 feet depending on image size; a 100-inch diagonal falls between approximately 8 and 11 feet from the screen. A pair of integrated speakers also helps out with presentations. The LS700-4K looks like a tasty little package for an unusually sweet price."

er ... Your "s" es all were replaced by "s" or "S" - Made it pretty impossible to read. Just did a quick find/replace:

As for the lag to release, wonder if viewsonic held the 4k release back to be sure the dynamic contrast issues Kraine saw in his review could be fixed? From the testing, it really comes across as likely an issue with firmware.

Just found a demo video of the x1000 UST. The picture quality looks pretty good considering the environment. The skin tone and color looks pretty impressive, not a surprise considering it’s rgb led light engine. The downside is the throw distance. With what looks like a 100” screen, the projector looks like it’s a whole foot or more from the wall.

ViewSonic LS700-4K

ViewSonic LS700-4K I am willing to purchase this to confirm input lag. The issue is if it close to it on 4k hdr I would love to keep it. However, if the numbers are far off, I just want to ensure I can return it.

ShopBLT's estimate just bumped from 7/1 to 8/12.

Don't have a problem waiting for something like this that exactly matches the feature combination I've been holding out for a while for, but sure would be nice to have an accurate estimate when

Has anyone seen any reviews of this yet? It also matches much of what I'm looking for, but would like to see some reviews first.

sooooo….. This is concerning...

https://www.viewsoniceurope.com/it/p...php?n=LS700-4K

Europe spec sheet shows "Input Lag: 50ms"

While US overview page: https://www.viewsonic.com/us/ls700-4k.html Still shows "Its ultra-low 16ms input latency provides faster frame-by-frame action."

Also in both sites the lumens output were reduced from 3500 to 3300. This, the delays and the not great reviews of the LS700HD are slowly burning my interest in this projector. I still hope it turns out good.

Looks like Viewsonic released a teaser video for it confirming 3300 lumens. Hopefully reviews are coming soon

For those need ing low lag 4k, looks like the ls700-4k is NOT the answer. My query sent to viewsonic (asking about the EU vs. US spec discrepancy) got the following response:

"Hello (me),
Thank you for bringing this issue to our attention, it does appear that LS700-4K would have an Input delay of 50ms. This was confirmed by our product management team.
We will be working diligently to fix this error on our website to ensure that the correct product specifications are displayed.
We are sorry for the inconveniences this may cause, and thank you again for bringing this up to our attention.

Sincerely,
(Support rep)
ViewSonic® Customer Support"


So.. Specs still look great at the price for a lot of use cases... But not my use case.

Some 4k DLP projectors can use 120hz source frame rates when in 1080p mode and this will reduce input lag to 25ms.

Looks like the LS700-4K is still not in stock? And no reviews yet?


I'm on the edge deciding between this and the Epson 5050ub, since they both are in the category of bright 4K(/enhanced), and the LS700-4K is significantly cheaper. But I really want someone to review it and to get some clarity about the lag.

This unit from Optoma looks like an interesting alternative to a true 4K projector:

https://www.projectorcentral.com/Optoma-ZU506-W.htm
https://www.projectorcentral.com/pdf...spec_10907.pdf

it is WUXGA (1920x1200) native but it accepts 4k HDR input and has an HDR display mode. There's no indication of input lag.

There is also the Optoma HD27HDR, which is native 1080p but accepts 4K HDR input and is optimized for gaming:

https://www.projectorcentral.com/Opt...HDR-Review.htm

with an 8ms lag with 120hz input.

I may have missed it but I don't recall anyone pointing out that the LS700-4K 1.3x zoom lens throw ratio of 1.13:1 - 1.47:1 is identical to the BenQ HT3550. So it's possible that both models might be using identical lens assemblies from a common supplier. The LS700-4K would join the HT3550 as the shortest throw 4K models <$40,000 (not counting UST models).

Any reviews out on this unit? Has anyone confirmed the input lag at all?

My LS700-4K arrived today! :)

I've been checking this thread at least a couple of times per week for months to find evidence that they didn't change their mind - that it really would eventually ship. So... now that I have mine, I can at least confirm for anyone else who has been doing the same. I'm afraid I'm not qualified to give a serious review. I know I'm thrilled with it. I've been using an Optoma HD806 for about 10 years and, naturally, there is no comparison. I'm not a gamer, so I haven't given any thought to the input lag concern some have raised. To me, it is the first projector out that is 4K with a laser lamp and a long(ish) throw and anywhere near its price point (and I am also delighted it supports 3D blu-rays), so life is good. I've been checking in with the seller every couple of weeks and he told me that I'd be the first to receive one because I had the oldest order (I paid in mid-June) and orders placed today won't be filled until January.

If I manage to get this thing set up to measure input lag, I'll report about it. For now, just know that it does in fact exist and this customer is delighted.

Amateur input lag experiment (LS700-4K)

I am a newbie, so I'll document my test, but I make no claims about the meaningfulness of my results. Hopefully, this is better than nothing...

I don't have a great way to test input lag, so I hooked up the the LS700-4K to my Dell G7 7588. I use it for work, but I believe it was advertised as a "gaming laptop" about a year ago. The display is a 1080p IPS. I've read that IPS isn't the fastest, but that's what I have for comparison right now. I wrote a script to display the time, wait a couple of ms, and then repeat. (To be precise, I did this in a terminal in a Cent OS session running in a VirtualBox.) To the eye, it seemed to usually scroll smoothly, but occasionally get stuck and "catch up". I took pictures of the laptop and projector screen in the background. For the first 5 pictures, the laptop was in 1080p mode and the projector was turning that into 4k. For the second set of 5 pictures, the laptop was in 4k mode (but the laptop screen was of course still 1080p). I took the most recent time on the laptop's screen and subtracted the most recent time on the project screen. I've attached an example picture.
Here are the results, in ms for the first set (1080p from laptop):
45
43

91 (theory below)

45
46
Here are the results, in ms, for the second set (4k from laptop):
48
45
44
44

40


My amateur view of this is that the projector is slower than my laptop screen by about 45ms and that the 91 was a case of the terminal stalling for a moment and then jumping ahead with the projector showing the frame just before the jump ahead and the laptop showing the frame just after the jump ahead. I have no idea how slow my screen is to begin with or what other factors may be going into this behind the scenes.



Within a week, I hope to be able to do similar test using a desktop PC and a Viewsonic VX2433wm. That monitor is also 1080p, but at least it is TN.


I hope this is useful to someone.
