Although I am excited about 4K, and the HK2288 in particular, based on this I'll want to see it at my proportional distance before upgrading from my existing Panasonic PT-AE8000U (1080p; LCD, 3-chip).
By that chart I'm halfway into the "4K would be a benefit" range. I'm at 138 inches diagonal from 13 feet. Good reference.

I'm excited to see reviews by both pros and end users come out, especially with regards to being able to disable XPR and/or enable 120hz at lower res somehow. Chances are, if one company offers 120hz, and it's just a matter of enabling it in the firmware, others might be pressured to follow due to competition.

projector people posted a video on the vivitek hk2288

Vivitek HK2288 Ultra HD 4K HDR Home Theater Projector

HDR looks great! 2000 lumens

Production/sale end of June.

A white version, HK2488 or something; will be 4000 lumens? not much else detail.

Expected pricing under 4000.
I'm curious between this and the Optoma UHD60 @ 2799

I'm curious whether this new Vivitek and the new Optoma will have 10.2gbps or 18gbps HDMI inputs on their hdmi 2.0 or hdmi 2.0a inputs.
Yes, if you haven't already found this out; just because a device has hdmi 2.0 or 2.0a; it doesn't mean you have the full 18gbps input.
(example: epson 5040ub; only has 10.2gbps HDMI but is listed hdmi 2.0a)

The specs on this looks more comparable to the Optoma Uhd65 rather than the 60 (I'm guessing price to also be comparable)

Yeah, best selling projector technology by far, R.I.P. OOOOkkay. The only sector DLP *doesn't* dominate is the low volume/low margin $4000-$15000 range. And that is not as lucrative as the high volume budget sector, the high margin pro installation sector, or the high margin theatrical sector - all of which DLP sells by far the most.

Take a look at Amazon and you will see DLP dominates the best seller list of home theater projectors. Or visualapex: http://www.visualapex.com/projectors...projectors.asp (LCD is there, you just need to keep scrolling down ) - Or check out all of the major commercial theaters around you and see what percentage of screens *don't* use DLP.

DLP ain't going anywhere, because its virtually everywhere

The Optoma UHD65 is the home theater version of the UHD60, so yes the Vivitek HK2288 will be competing with the UHD65 primarily. The UHD60 has a white segment in the color wheel to boost brightness, mainly for use with moderate ambient light/business use.

I'm a big fan of DLP, but that's just not true.

I own one and haven't been able to be convinced to upgrade by something for something far more expensive with better contrast, but to say it's an unqualified "the best", period, is just not true.

It's the best in 3D, absolutely.
It's amongst the best in ANSI contrast, (depending on the model), but the question about how much that matters vs on/off is debatable.

It's the best in motion resolution, yes, that too. (this is what makes it the best for 3D as well, because of triple flash, so 3x repeats per frame per eye, with no cross talk).

But without FI the added sharpness conferred by having zero pixel transition times only makes judder more obvious, not less.

Is it the best in terms of lumens? No, Epson beats it, easily.

Also it's hardly appropriate to compare movie theater DCI projectors, which are 3-chip designs so no rainbow effect.

Rainbows don't bother me, but they do bother a number of people so to say DLP is the best is just wrong. And that's not even getting to the contrast. It's flat out the worst in terms of on/off, or close to (maybe some dirt cheap LCDs have worse contrast).

Most popular != "the best".

So, what is the difference, if any really, between the 2288 and 2299 models besides chassis color and price?

EDIT

I guess the 2288 was replaced with the 2299.

I just had to show my cousin that this is not a true 'native' 8.3 million pixel projector (as the marketing claims) but just so that nobody else is confused (or mislead) here is the factual information from TI on their .66 DMD.


http://newscenter.ti.com/2016-01-06-...-and-education


Pay attention to this line "The DLP 4K UHD solution uses the fast speed of the chip with advanced image processing to deliver more than 8 million pixels to the screen with just 4 million mirrors. Each mirror is capable of switching over 9,000 times per second, creating two distinct and unique pixels on the screen during every frame to deliver full 4K UHD resolution."


This is similar to the wobulation methods that have existed for many years (subpixels), they used similar techniques on many rear projection TV's.


I am not knocking the tech or the brand (I own a 1080p Vivitek that is used for gaming) so please do not take my post out of context, I figured that if my cousin can be mislead by the marketing then others could as well.

If you dig deep enough the HK2288 and HK2299 are both listed on the U.S. Vivitek site but the HK2299 doesn't show up on the Taiwan Vivitek site while the HK 2288 does. Very confusing. The only difference that shows up when you run a spec comparison between the HK2288 and HK2299 on the U.S. Vivitek site is contrast, but since both models are said to have RGBRGB color wheels that wouldn't account for the contrast difference. Very confusing.

I am demoing the 2299, not too impressed. I have an Epson 5040 for comparison. The vivitek is too loud for my taste and will be going back.

I am also little bit disappointed with this projector. I have some issues, first there is no keystone on the menu, very weird, second there only two options for the lamb mode ( normal, and boost ). I wrote an email on vivitek nobody answered, that’s make me to worry, also there not manual on the web site and of course no download firmware for future upgrades. I hooked up my Apple TV 4K connected with onkyo Tx-nr656 and when I play 4K from iTunes the sound switch to airplay, I don’t know why. With the amazon fire tv the sound come alright like suppose to be ( Dolby Digital + ). I didn’t hooked up yet on the ceiling ( this thing is huge and have 30 pounds I don’t know what have inside and other 4K pj that weight less doesn’t have ). The image is better from benq 2050 but not wow. I have 30 days for return, I am gonna keep it for a while I am gonna hook it on the ceiling and I am gonna do more testing before to return it. The only problem is that I am gonna have to pay the shipping since I am living in south Florida and there no frys near to me.

That’s disappointing. What kind of 4k material were you feeding it... UHD, gaming, or streaming?

I have the Optoma uhd60, uses the same DLP XPR chip.

while it might not be as sharp/good as sony true 4k projectors, for the price its DLP 4K XPR is quite impressive.
I am feeding it all kinds of 4k signals from blu rays, UHDs, and pc games 2160p. its got 18gbps inputs
They all look pretty incredible to me, and price it was amazing.

I'll have fun with this until a better/true 4K projector comes along.
It was perfect because my older 1080p projector needed repair and instead, got this for 4k fun playtoy until something more substantial comes along.

the wobulation effect is improved from before. I have an old 1080p samsung RPTV DLP set that wobulated 960x1080 to 1080p. That thing was decent back in 2005; but it wasn't as sharp. the 4K XPR chip is impressive, sharp, and improved.

i demoed the epson 5040ub, and that pixel shifted 2mill to 4mill pixels and accepted 4k. i sent that back, it wasn't sharp enough for me.
the optoma uhd60, pixel shifts 4mill to 8mill pixels and it was noticeably sharper and impressed me enough to keep it, hands down no contest.
it looked as sharp as my 4K UHDTV and that was enough for me.

One known difference is that the UHD60 has a non-RGBRGB color wheel while the Vivitek has an RGBRGB color wheel like the UHD65.
