Optoma ZH55, HD29Darbee, GT1080Darbee HD Projectors at CES 2017

The Optoma ZH55 laser-illuminated projector looks very interesting, and the HD29Darbee and GT1080Darbee keep 1080p alive for less than $1000.

Given the limitations of placement and screen size, I fail to see the point in paying for Darbee tech. What am I missing?

the Optoma ZH55 is the one that does HDR right? so one might assume that it accepts 4k signals just downscales the resolution while leaving the HDR intact?

No lens shift is a deal breaker for me as it is impossible for me to get my projector perfectly aligned lol... I lack said skills. ^^;;

That's why they make fully adjustable projector mounts that can produce the same results as vertical and horizontal lens shift.

HDR + laser + FI +3D in an affordable 1080p package would be hard to pass up, compared to spending 2-3x as much for the UHD 60.

Although supporting HDR10 in a 1080p DLP probably means having HDMI 2.0a or at least a firmware modded HDMI 1.4 with HDR enhancements (if PS4 original can output HDR10 via HDMI 1.4 chips, then to stands to reason that any HDMI 1.4 projector theoretically should be able to consume it from a hardware perspective. And EOTF support is mostly done via a lookup table AFAIK which should also be moddable by software).

******It also features frame interpolation (which, of course, most AVS Forum members would disable) - Wrong. I like the video smoothing. I mad that the industry has dropped the High Frame Rate talk and it's all about HDR.
Why can't we have High Frame Rate, 3D, HDR, DTS X - Atmos all on bluray and uhd?

Probably because they won't make money on HFR because every TV already supports it, even grampa's 200 pound boob tube.

The laser one is 3000 lumens and goes for 2500$. So, compared to the UHD60, you give up 4K and HDR for laser backlight. Basically long bulb lifespan, probably quieter, and faster dynamic adjustments and maybe even fade to full black (although that doesn't matter in practice all that much, and I say this as a sci-fi movie buff).

I guess you can make an argument for a lower TCO for the laser unit, but considering it's already obsoletem no WCG, no HDR, no 120hz (2017 and it's not even UHD compatible in any way? uhh, that's a stretch).

They could have made the sale a much more competitive choice by offering us 120hz 1080p or even 60hz frame packed mode for NVidia 3D, and possibly even WCG + HDR10.

It's going to be a very tough sell for just the lasers when the UHD60 is basically the same price. Sure, you get to buy lamps instead of never losing any brightness thanks to lasers, but seriously, I really wonder how that makes any sense. At least give gamers a reason to buy it, like 120hz and HDR. 3000 lumens HDR on a DLP should look almost as good whether it's at 4K or 1080p.

Thanks for those links Mr Chan.

On one of them it mentions 91khz max horizontal frequency which is like 80hz at 1080p, but it also mentions 85hz and in brackets (120hz), so I'm wondering if 85hz is at 1080p (reduced timings?) and 120hz at 720p (my w1070 does this already, somewhat, it actually switches into 1280x800). It also says stuff about 118% HDTV wide colour gamut and of course 20k hours.

Seems at least it has some potential. And makes me think laser phosphor for the 4K DLP versions shouldn't be too far behind.

Thats actually not how that works... at all.

The purpose of those mounts are to get the projector level and square, that has nothing to do with truing (lining up the image) to be perfectly lined up with the projection screen where as len shifting has the ability to shift the image without creating distortion to the image. Sorry hard for to properly explain but yeah needless to say mounts do not offer that.

Correction: I suppose technically Up and down alignment could be possible with different size piping to change the drop height but right and left would need to be on some kind of rail system to slide the projector left and right but thats not typically the intent so that relies more on the user to perfect calculate everything out thus thats when lens shift comes in handy for that extra fine tuning.

Looks like they have a product page on their Chinese website.

There are mounts with articulated arms that allow a fair amount of both horizontal and vertical movement to shift the image around while keeping it square with the screen, which effectively produces the same results as shifting the image around with lens shift.

In fact you will technically get better results with a fully articulated mount than lens shift because lens shift can take the image out of the sweet spot in the center of the lens and project it from closer to the edge of the lens. Most lenses are more accurate in the center than toward the edges.

There's even an image of one of those fully adjustable mounts right here on AVS Forum:

I can't read Chinese, but it appears to have HDMI 2, but does not support 4K resolution.

I'm intrigued by what exactly they listed (120hz) for, probably 3D shutter glasses support. Not too hopeful about 120hz 2D.

Do you have a recommended model / brand one to go with that offers this?

I can't personally recommend a model/brand as I've always had lens shift and never needed a fully adjustable adjustable mount. The image I previously posted above as an example is of the Vantage Point CGUPM12 which dynamically rotates, tilts, and swivels in any direction to allow up/down, left/right, forward/back projector movement. There's a thread about it right here on AVS Forum complete with images: Link

Vertical lens shift is very important to me because I don't want to bang my projector on my head or get blinded by the light as I walk to my couch. For me, I prefer to have the projector out of reach so there is 0% chance of that happening, unless I am very close to the screen.

I could get around it by using longer extension pipe but that adds weight and I'm already at 18-inches. Yes, my ceilings are that high. (13 feet).

has there been any update on the Optoma ZH55? 1080p with HDR seemed like an awesome idea but never heard anything since the announcement
