Irvine, CA March 15, 2019

AAXA Technologies is excited to announce the release of the AAXA 4K1 LED Projector, a true native 4K 3840 x 2160 resolution mini projector.

The 4K1 delivers cinema level resolution by employing the latest Texas Instruments DLP technologies featuring a native 4K digital imager mated to ultra-long-life Osram quad-cast LEDs. With its powerful 1500 Lumen optical engine, the 4K1 can deliver a vibrant 200” image in crystal clear Ultra-HD.

The 4K1 features dual HDMI compatible inputs, remote-controlled focus adjustment, powerful twin 2-watt speakers, and an onboard media player.

True 4K 3840 x 2160 resolution

The AAXA 4K1 employs a state-of-the-art optical system based on Texas Instruments DLP’s very latest 4K MEMs imager. The light-source comes from premium Osram “Quad-Cast” LEDs and the image is passed through premium grade optics including a high MTF lens-set which ensures no image degradation. The result is true on-screen Ultra-HD resolution and a vibrant, clear, and sharp image.

30,000 Hour Osram Quad-Cast LEDs

The 4K1 employs premium Osram quad-cast solid-state LEDs. Quad Cast Red/Green/Blue/Blue LEDs are able to produce a rich and vibrant color gamut that cannot be found in color-wheel or white LED based projectors. Solid-state LED technology enables long life-spans, instant on/off, and is much more durable than lamp-based projectors. With a 30,000 hour LED light source the 4K1 can operate 8 hours per day for more than 10 years without needing a lamp change. And of course the LEDs are environmentally friendly and mercury free.

Remote Electric Focus (REF)

The 4K1 employs remote electric focus technology that allows the user to adjust the focus via remote control without ever touching the projector. This feature enables better control over adjustments and flexibility for ceiling mounting or frequent location changes.

Ceiling Mount Compatible

The 4K1 employs a custom 3-hole ceiling mount (mount sold separately) for secure vertical mounting applications.

Premium Dual 2 Watt Speakers

The AAXA 4K1 features twin 2-watt speakers that deliver room-filling sound for an immersive viewing experience.

Connectivity and Media Playback

The AAXA 4K1 features twin HDMI inputs, an AV 3.5mm input, as well as an onboard media player capable of decoding digital videos and pictures. Content can be stored directly on a Micro TF card or USB memory stick and played back directly from the projector. The 4K1 incorporates dual 2-watt premium speakers to deliver vibrant sound in a small form-factor.

Pricing

The AAXA 4K1 Pico Projector is available for sale at www.aaxatech.com for $999 and through our excellent retail partners.

I was going to pick up the updated XGIMI H2 (1500 lumens) for my newly-finished basement, but this 4K1 model looks pretty intriguing. I setup a few XGIMI H2's last year (the 1350-lumen model) & they were super-awesome...tried out one in a barn with a 25' diagonal & it looked surprisingly great! Curious to learn more about the new Aaxa, however...4K LED sounds pretty fantastic, especially for a grand! Of course, one of the biggest benefits of the XGIMI is that you can shoot it sideways, so it doesn't have to be mounted overhead, which is really convenient for certain room configurations.

Debating on pre-ordering or waiting for reviews to show up online...

wheelee 03-17-2019 11:27 PM

2019 will be the year of 4K projectors with competitive pricing & since all this vendors use the DMD/ chipset it all boils down on how they implement picture quality in their product. Hope someone review & compare this with other 4K pj's out there.


I was wondering with all those enhancements like HDR, HDR HLG, different implementations of color wheels & other color manipulation - would the film still come out as intended to be or are we being fed eye candy features that where not there?

The 3500-lumen Viewsonic PX747-4K is already down to a grand on Amazon, and the slightly-older Optoma UHD50 isn't far behind, so competitive pricing is definitely in the works! What makes the Aaxa stand out is the small size, lower power requirements, and LED light engine. As is typical with most picos, there doesn't seem to be much beyond that in terms of HDR or anything, or even a zoom lens. I'm curious if XGIMI will get on the ball with an H3 or something!

We'll have to wait for reviews, but then i don't see how this would work great in any of those settings with unknown brightness rating and weak contrast. The only thing it has going is 4k, but there are ton of non 4k projectors that are cheaper and brighter that would works much better in those mentioned settings. Even with built in speakers like XGIMI H2 for half the price.

I was assuming it was battery powered, after more reading it seems it’s not. If it was, you could just plug in a streaming stick and prop it up anywhere. You can usually overcome weak brightness and contrast by simply moving the projector closer to a surface and having a smaller screen size. This would be much much easier if it was battery powered.

The quad-cast LEDs may be the most interesting thing in this announcement.

No colour wheel? If there's no RBE then there goes one of the biggest issues with DLP. Extended colour gamut? Nice!

Now, if TI were to make a real 4K DLP chip, and not a shifter ....

Over the years AAXA LED projectors have gotten consistently good professional reviews and have also been highly recommended by many folks on this forum. They have a good track record of delivering above average performance at below average pricing. Try looking up reviews of the 1080p AAXA M6 for a hint of what to expect.

Dave in Green 03-19-2019 01:05 PM

The AAXA M6 was rated at 1,200 lumens but independently tested by projectorreviews.com at a maximum 835 lumens or about 70% of advertised lumens. Taking 70% of the 4K1's 1,500-lumen rating would put it at 1,050 measured lumens. But there should be some increased perceived brightness from the Helmholtz-Kohlrausch (HK) effect that has been demonstrated in RGB LED projectors like the 4K1 that display equal white and color brightness (see link below). So maybe ~1,100 perceived lumens, which is good for such a small LED projector but won't be enough for those who want to throw larger images with ambient light in the room.

Not likely. Considering how poor the real world contrast is of almost all of the current 4K DLP projectors, I'm not sure what truth in advertising matters.

Reality remains that there is almost no DLP 4K projector (or non-4K) that can garner a 2,000:1 contrast ratio in the real world. So, this is probably worlds closer to reality than anything else on the market.

I hope AAXA sends out a model to Projector Reviews and Projector Central to get some good feedback.

1,500 LED lumens.

Not ANSI. So, expect about half that much in the real world. Maybe up to 1,000 real world lumens max. That's still plenty for a 120" diagonal screen.

But, it's not a light canon. Just a solidly bright LED projector. Maybe on par with XGimi models.

Still, if they can ramp the power to the LEDs fast enough, turning them all completely off for scene transitions could yield an impressive FOFO contrast and very low black floor. Has any of the previous AAXA DLP 1080P models done that, do you know ? I've read the PC and PR reviews of the M6 and did not see any notes on full on/off contrast.



How does the Dynamic Black lamp dimming translate to separate RGB(Y) LEDs ? Lamp dimming on some Benq lamped models can drop lumens as low as 30% of full power, so I am wondering if LEDs can drop output lower than lamps can or is it purely on/off. It seems like they should, as lamps have strike issues if power drops too low. What would a deep space scene look like if the LEDs were only producing 5% power, ie deep black but still lousy contrast ?

Here's how projectorcentral.com answered a question about the AAXA M6 review of why they don't measure actual ANSI contrast:

Hi Ron. My predecessor Evan Powell discussed in an article a while ago the issues with attempting to measure true checkerboard ANSI contrast with any projector -- short of a dedicated 100% dark light cave in which to recreate a true blackout condition you can't rely on anything even remotely characteristics of consistent results. And I could argue that even ANSI fails to properly recreate meaningful results that mimic typical viewing conditions.

And as for any numbers claimed by a manufacturer for contrast ratio -- whether full on/off or native/dynamic...take it with a grain of salt. These figures are really only useful for comparing one model from another in a particular manufacturer's line-up.

Yes, I read that. I guess I am the only person on the planet who values a completely black screen when it is supposed to be completely black. FOFO is not a useless measurement if the reader understands what it means.



It does not answer my question about RGB LED light engines, either. Are they capable of adjusting brightness percentages lower than lamps (30%) and has any manufacturer including AAXA implemented such brightness control including complete shut down for intra-scene transitions, ie FOFO. It seems like reviews should mention this if it is something that LED light engines can do but lamp based engines cannot.



Even when it comes to Dynamic Black lamp dimming, a UHP lamp that is dimmed is (or maybe not) still producing the same relative proportions of Red Green and Blue along with many other colors (which then need a color wheel to filter out). There should be an advantage of RGB LEDs that are producing only specific wavelengths and can control the brightness of each color individually, but it would require some tweaking of the TI Dynamic Black algorithm, so why is there no mention of this in their M6 review ?

Dave in Green 03-20-2019 01:39 PM

I don't know the specifics about how far current projector LEDs can be dimmed using Dynamic Black lamp dimming. I know that the earliest LED house lamps I bought were not capable of being dimmed but the latest ones I bought can be dimmed to <10% of maximum brightness. I expect that projector LED technology will continue to advance as LED projectors take more significant market share from UHP lamp projectors. As that happens TI will certainly put more effort into optimizing their chips for improved LED performance. I'm pretty bullish on LEDs in general and will consider an LED projector for my next upgrade as long as the price/performance continues to improve to a level that suits my preferences.

zombie10k 03-23-2019 06:37 PM

it's interesting they are including an extra green LED. This is likely how they are claiming 1500 lumens, it probably a heavy green torch mode setting.

http://hometheaterphotos.com/projector2/aax_4k.jpg

I'd guess around 700-800 lumens @ D65. even so, this might be a nice replacement for my LG PF1500 which has been running perfect for 3+ years with a lot of use.

Likely some creative graphics person in the marketing department who knows nothing about projectors created the image with two green instead of two blue LEDs, no one in the marketing department approval process knew any better and no one in engineering was given a chance to sign off on it. :)

It looks like we have several players in the 4K pico LED arena:

1. AAXA 4K1 ($1000)

2. Optoma UHL55 ($1600)

3. JmGO X3 ($1150)

4. XGIMI RS Pro 4K LED (TBD)

I've had a pretty good experience in the past with various AAXA projectors (P300, P300 NEO, "HD Pico", etc.), but the JmGO X3 might be a good contender as well:

My first LED projector was a 500-lumen Viewsonic back in 2012, which I later upgraded to the 800-lumen model. I feel like 800 lumens is really the minimum you need to have a solid big-screen (100"+) experience with an LED projector. I've installed a ton of XGIMI H1's & H2's for family, friends, and small businesses over the last few years, ever since H1 debuted, with great results! My brother is running a 160" screen with his XGIMI & it looks absolutely phenomenal in his basement HT. They are not like the old crappy tiny LED projectors were/are; the newer pico-class LED projectors have come a long way over the last five years or so. Most are still far from perfect (lack of a zoom lens in most models, lag in some of those without game mode, etc.), but they are plenty bright & work great for home theater usage. I've been extremely happy with many of the models I've personally owned! If you haven't had a chance to check out something like the XGIMI H2-Aurora, then it's definitely worth seeing in person if you get the opportunity!

Pico = tiny, small, minute?

Yes those pico-pico burrito came a long way to what they are now & the difference to non-pico is that those are still using old age traditional casing because of the added mechanical features. Many of the so called non-pico uses the same DMD/ components as the pico's & are now also turning to LED/ Laser. Some of those pico could also be very bright like the Dangbei F1 which uses 1400 ANSI lumens.


Got a Vmai(icodis) M200, literally a Palm projector for my son's birthday & he was happy about it. I couldn't believe that something this tiny can display such.

Hah, I was just thinking the same thing when I posted my previous post...I had to google to see if projectors like the XGIMI H1 were still considered pico projectors, as they definitely aren't palm-sized, but apparently they are still pico-class for a variety of reasons (no zoom lens, no lens shift, Chinese menus, and so on). However, the H1 outclasses nearly every bulb projector I've ever owned in the past, so I would definitely consider it a viable projector for dedicate HT use (and have setup many of them that way!). Instant-on, doesn't overheat your room, doesn't need a lot of cooling space, super sharp clarity from the LED light engine, ridiculously long LED bulb life, etc.

I think right now I've got it narrowed down to either the Aaxa 4K1 or the JmGO X3. My goal is to build a micro 4K LED 5.2.4 Atmos theater in my current tiny half-finished basement. My previous micro-build was using a BenQ HT2050 with a 5.1 Bose clone in a similar space, and it was an awesome setup!

I am very familiar with XGIMI, as a matter of fact I've ordered H2 and cancelled the order after considering the trade offs. At that time I got a deal for UST projector and never looked back. Now that I have tried it I don't see myself downgrading to traditional front projectors, so the only reason I would get one is to have a cheap 4k to travel with, but will hold of until there are more options with reasonable prices.

This^^

This little guy becomes REALLY interesting for $600...

However with the fixed throw ratio, no HDR, 2W speakers, no 3D, no frame interpolation, only 1,500 lumens... it doesn't seem very compelling for $1,000.

The quad-LED light engine, however, is very compelling, from an industry perspective. I don't believe it will be enough to forgive it's shortcomings above, but I am very interested to see how the quad-LED performs. This projector will be a good case study. I'm wondering if that tech can be brightened up and be implemented more often in DLP projectors to open up target audience to those that suffer from RBE. In theory it should also allow DLP to compete more in the "more color lumens" discussion.

JackB 03-28-2019 04:51 PM

I've owned an LED mini, the LG PF1500, for close to four years. I use it in a dark HT room with a 1.0 ST screen. It is plenty bright so I expect that this AAXA would have plenty of brightness for anyone with conditions similar to mine. The concern I have is that if AAXA hasn't done a better job with controlling the dark light scene contrast than Optoma did with the UHL5500 then it wouldn't work for me. I sent the 5500 back because the 4k chip was so inferior to the 2K one in the PF1500 in the described situation.However, $999 is a long way from the $1,700 that the Optoma commanded when I bought it.

If there was a way to tweak the AAXA to get anywhere close to the 1500 in low black level contrast I would certainly try it.

Other regular-bulb projectors are already available in the $1k price range, so I'd like to see a review before pulling the trigger.

Unless AAXA has the magic formula you will find that these 4x UHD shifters have substantially poorer low black level contrast than 1080P DLPs of the past few years. I tried two of them, including the led Optoma UHD5500, and returned them both. My four years old led PF1500 had much better blacks. It has to do with the shifting technology without a dynamic iris.

K so has anyone tried the axa 4k1 led projector?
If its blacks are semi in the pf1500 range then i will buy an axa projector?

So far no projector with a 0.47" XPR chip has been able to match the native black levels of the older, larger 1080p chip. It seems to be an inherent characteristic of TI's DLP DMD that can't be corrected at the projector manufacturer level.

Any chance that 2020 brings a larger .66 chip and better black levels?

Dave in Green 04-05-2019 12:46 PM

There already is a larger 0.66" XPR chip with better black levels -- TI's DLP660TE. Unfortunately it's only available on a few older models and to the best of my knowledge no new projectors have been announced with this chip. For better or worse the DLP projector industry seems to be focusing on the 0.47" 4x shifting 1920x1080 micromirror XPR chip rather than the 0.66" 2x shifting 2716 x 1528 micromirror chip.

Kaido 04-09-2019 12:10 PM

My buddy ordered the Aaxa 4K1 - I'll have to get some hands-on time with it after it arrives. I'm currently leaning towards the BenQ HT3550, however.

Playing with the AAXA 4K1 now. Just a laundry list of initial thoughts, and unfortunately, most of them are negative so far:

1. Size is nice. Fairly compact.

2. Fan noise is awful. For this reason alone, this is immediately a no-go for my tiny HT room. It has 3 brightness settings (low/medium/high). Low (Eco) is tolerable for fan noise, but the brightness drops so much that the color literally, visibly changes on the screen. Oddly enough, the fan is not a nice purr, it sounds like an aging laptop fan, kinda janky. At Medium (Standard), it sounds like a hairdryer in the next room. At High (Bright/Boost), it sounds like a portable travel hairdryer. Ridiculous. I don't know if I've ever used a projector as noisy as this!

3. Brightness is somewhat pathetic. The 1350-lumen XGIMI H2 blows it away. My first decent LED projector as the 720p Viewsonic (500 lumens). It was adequate, but not great, and you really needed a blacked-out room for decent performance. Then the 720p Viewsonic 800-lumen came along, and I thought "ah okay, 800 lumens is what I consider to be the minimum requirement for an LED projector to look good". So for the past half-dozen years, that has pretty much held true. The AAXA, however, reminders me of those original Viewsonic models. I would say it feels like a 700-lumen model...like almost at the 800-lumen "minimum" requirement, but man, I'd sure like the 4K1 to be a LOT brighter - even in a blacked-out room, at max brightness, I still wanted just a bit more brightness out of the AAXA. I've gotten the XGIMI H2 at a 25-foot diagonal with surprisingly decent results; I'm shooting the 4K1 at 120" & I'm not super thrilled with it.

4. Sharpness is awesome. Like when iPhones went to Retina screens...text looks great! Readability is the best I've ever seen on a projector (this is my first experience with a 4K model). The clarity is really excellent. Electronic focus is nice (I miss the H2's autofocus, tho!). However...

5. I see what you mean about black levels. The 1080p XGIMI is FAR better. That 2000:1 contrast ratio hurts it, as well. Clear, but not with that vivid punch you really want. I've setup a ton of 1080p XGIMI models (H1, H2, Aurora variations, etc.) over the last couple of years & have been really, really happy with them (for what they are...Asian TV show ads on boot-up, Chinese language menus, etc.). This AAXA model needs the the mojo that XGIMI has. The 0.47" 1080p DMD in the XGIMI is noticeably superior to the AAXA's 4K chip for everything but resolution. I watched some movie clips & some reference clips on the 4K1 just as a quick test & wasn't thrilled.

That's all I had time for today. Next week, I'll see if I can borrow it & get some more hands-on time with a 4K player, an XGIMI, and a BenQ, just to compare. Primarily due to the fan noise, but also the far-less-than-expected brightness level (at which max brightness = horridly loud, not like tiny fan annoying loud like most budget pico projectors, like LOUD-loud), I will not be going with the 4K1 for my home theater. The BenQ HT3550 is at the top of the list right now. I'd really like to test another 4K LED model, such as the JmGO X3 or the Optoma UHL55, just to see how the fan noise, brightness levels, black levels, and contrast ratios compare in-person, but given what I've seen with this model, I wouldn't expect to be overly impressed with the X3 or UHL55. If you were to offer me an H2 vs. a 4K1, I'd take the H2 in a heartbeat. I'd even take the H1 over it! Bummer.

wheelee 04-18-2019 08:32 PM

With that fan speed, I can't imagine the dust blobs you'd have to clean out every now & then.
I guess marketing pushed R&D on this model.

Xgimi announced a budget 4K last year & every one was expecting it on 11-11 but it wasn't there, now in their bbs a lot are asking about it & the moderator said just to wait patiently for the surprise coz it would be worth it! now expecting it to be released on 6-18.

Don't bother with the UHL55. I sent it back. Everything was good but blacks and contrast were much worse than my four year old PF1500.

Yeah, and I didn't like the PF1500 all that much personally (or the UST model)...went with the XGIMI H1 after the LG's, loved it, and started doing those for friend's HT's. The H2-Aurora is a steal for what it is...nice built-in speaker, amazing brightness & picture, auto-focus that actually works, can shoot sideways so you don't have to mount it overhead, etc. But my previous BenQ HT2050 had just a bit of an edge over it in terms of overall warmth, so I'm thinking the HT3550 will be a really nice 4K model for my basement theater. My goal is to build a "micro" Atmos theater (5.4.1) with a 4K projector & I was really hoping to go LED with it. Ah well.

I hope they make a 4K model like the H1/H2, and I hope it's awesome! Not having a lot of confidence in the 4K chip tho, based on what I've seen with the 4K1 model so far. I'll have to make a video of the fan noise on the AAXA...it's a real turn-off. I don't know if he's going to keep his 4K1 or not...they have a 30-day return policy, so he's going to give it a couple of weeks, and I'll see if I can grab an XGIMI to compare.

IMO the key to the PF1500 was having it calibrated properly using all of the tools available. Mine was and looks just as good as my 10K SharpVision 20000 and my JVC RS40, which I ended up giving away. So pay the price and have your H2 calibrated and you may never replace it. BTW, does it have the ability to be isf calibrated?

I don't think it does (at least not back in the H1 days, I'll have to check with XGIMI or Kaya to see if that story has changed, but I doubt it!). tbh I'll probably keep my H2-Aurora forever...it's been a tank! I use it with a 135" ES Yard Master 2 when it's warm out & it's been really fantastic for super-easy outdoor movie & gaming nights (previously had a Walmart inflatable 12' screen, which was a lot of fun, but the YM2 has been a treat with how easy it is to setup & doesn't require constant air, power, and motor noise to operate!).

The 4K project is for my "click-n-go" basement theater, which is why I wanted another LED projector model...one that was fixed on a wall or ceiling mount, always plugged in & ready to be clicked on & start playing games or watching shows. It's not that there's a huge difference in accessibility between a traditional bulb projector vs. an LED projector, but there is something awfully approachable about just clicking a button & having it pretty much be "instant-on", while not heating up the room, being too noisy, or being too big for the space. Those are kind of minor things, but in my family at least, when I have the XGIMI setup indoors, it gets used a lot more often because it's so easy to use! It's almost like a rotary phone on the wall vs. an iPhone...with the iPhone, you just swipe & it's ready to go...the XGIMI models have been the same way for everyone I've installed them for, just super easy to use & great bang for the buck!

Dave in Green 04-19-2019 08:48 AM

Surprising that the 4K1 would underperform previous AAXA models. AAXA certainly has enough experience with solid performing models not to have messed up the 4K1 design. I suppose there's always hope that this was an early production unit that wasn't up to spec. I guess we'll see when more units are out in the wild and serious testing with calibrated test equipment is performed.

Dave in Green 04-19-2019 09:15 AM

Thinking a little more about the 4K1's fan noise, AAXA has always focused on the smallest possible projectors for portability. With dimensions of 8.3" x 7.2" x 2.4" the 4K1 is certainly one of the smallest 4K models on the market. Small case size is a disadvantage for fan noise because there's less room for internal baffling to muffle the sound of the fans. Also the more lumens produced the more heat generated and the more cooling air required.

Looking at an image of the 4K1 there are 3 small cooling fans <2" in diameter flush with the projector's backside. Small fans like that can tend to have a more annoying sound than larger ones and it's also likely they wouldn't all be spinning at exactly the same speed. That has the potential for setting up harmonics that can be even more annoying.

The quietest projectors on the market typically have cooling fans buried deep inside the case where their sound is more muffled. So it's probably best when shopping for a home theater projector where subdued cooling fan noise is desired to stick with projectors with larger cases.

I have several AAXA projectors & am a really big fan of the P300 NEO in particular, for what it is. My primary issue with the 4K1 is the excessive noise; I'll take a video of it next time I play with it. Second issue is the brightness; not awful, just not to the level I was expecting. Maybe it's just a dud unit, but given the quantity of fans, I doubt it! :(

You are obviously not new to projectors but what did you really expect from a compact box that needs to cool down the light source effectively and non ansi lumens rating. I still see the real cost of this is half of what they are asking otherwise it's DOA.

Prior to the 4K1 the 1080p M6 was AAXA's top projector. Projectorreviews.com gave the M6 credit for being "quite bright. Almost no competitors this size have measured brighter." However, they really dinged the M6 for fan noise:

Quote:

AAXA has not provided a measurement for fan noise, but I can tell you it ranges from barely audible in ECO Mode, to downright un-ignorable when operating at full power. The mid-range power mode, Standard, has audible noise as well, though it is less loud than when operating in Bright Mode. Standard will be your best bet for combatting that loud fan while still having a bright image.

Even so, you’ll likely need to speak up in order to overcome that fan noise, because ECO Mode isn’t likely to cut it as far as brightness goes in you’re presenting. The fan noise at maximum in a room full of people will most likely be acceptable, but it’s hardly ideal. My best guess is that the audible noise is upwards of 40db. That’s super loud.

When the volume is turned all the way up, the fan noise becomes less noticeable, which is good because the projector would be completely unusable for movies if this wasn’t so. Gaming would be difficult as well. Whether you’re using the M6 for entertainment or business, you’ll likely to be able to overcome what must be the loudest fan ever on a pocket projector.
So it seems that a version of Hoffman's Iron Law for speakers (You can only have 2 of 3 -- bass extension, efficiency, small enclosure) also applies to projectors: You can only have 2 of 3 -- high lumens, low fan noise, small case.

Well, the XGIMI H1 & H2 do a great job, with a taller frame, but in about the same footprint. The 4K chip obviously requires some heavy-duty cooling though. The 4K1 is my first experience with a 4K projector; HT3550 is currently on my radar! I still have a month or two's worth of work on the other half of my basement, so I'm in no rush, but I'm glad I've been able to narrow down the choices somewhat...

Yeah, that was actually one of the reasons I skipped the M6. I think I'll have to live with a giant HT3550. The sacrifices we make with our #firstworldproblems :D

Hi, I saw the mention of the XGIMI H2 as a "half price alternative". Not so fast.

The H2 is sort of most like a low resolution Optoma UHL55 - big speakers, etc. But the H2 is only WVGA resolution - we're talking DVD here, vs a 4K UHD. Definitely not remotely close as an alternative as you move back 20 years in resolution. - no matter what the input lag...

My bad. You are correct - 1080p. It was a different pocket projector someone was trying to get us to review but was only WVGA. I simply spaced on that. We have an H2 arriving any day now to be reviewed. (I tend to avoid projectors with things like WVGA resolution,(

It does not answer my question about RGB LED light engines, either. Are they capable of adjusting brightness percentages lower than lamps (30%) and has any manufacturer including AAXA implemented such brightness control including complete shut down for intra-scene transitions, ie FOFO. It seems like reviews should mention this if it is something that LED light engines can do but lamp based engines cannot.



Even when it comes to Dynamic Black lamp dimming, a UHP lamp that is dimmed is (or maybe not) still producing the same relative proportions of Red Green and Blue along with many other colors (which then need a color wheel to filter out). There should be an advantage of RGB LEDs that are producing only specific wavelengths and can control the brightness of each color individually, but it would require some tweaking of the TI Dynamic Black algorithm, so why is there no mention of this in their M6 review ?

Hi, A couple of things. While LEDs and lasers can be dimmed or turned off to behave like a dynamic iris, the question isn't can they do that, but why don't they. I've been calling on manufacturers to do just that. Let the laser (or LED) engine emulate a fast iris. Long ago, we had hoped Epson's LS10500 would be able to do that, but no.
Off the top of my head, the most obvious example (and the only one I'm sure of), of using a laser engine as a dynamic iris, is the Sony VPL-VW995ES. Great projector but the $40K list price is going to keep it out of most people's homes. Still, no reason why we shouldn't see more of this in the future, as lasers especially, but also LEDs start to dominate the marketplace. -art

Off the top of my head, the most obvious example (and the only one I'm sure of), of using a laser engine as a dynamic iris, is the Sony VPL-VW995ES. Great projector but the $40K list price is going to keep it out of most people's homes. Still, no reason why we shouldn't see more of this in the future, as lasers especially, but also LEDs start to dominate the marketplace. -art

Art,

It would seem that when you visit the shows and talk to the vendors you would be able to ask the question, "Why not?". They usually have an engineering manager at the show and your position and reputation in the industry should merit a detailed answer.

I'm guessing led or laser dynamic iris emulation either doesn't work well or there is product line impact that doesn't work well for them. In my former life in computer product development if we added features to our product and gave it a new number or model designation we had to measure the impact it would cause on the current line and absorb the profit loss they would encounter because our advanced features lost them sales. Of course, the competition always did that anyway and we would lose out. That company of mine no longer makes hardware of any significance.

I think you need a special dimmable LED & a dedicated circuit for those to work for dimming.


not sure if these covers LED's used in pj's

Differences among various colored LEDs could be problematic in arrays designed to mix colors to produce white light. Color appearance could shift unacceptably when dimming if the different color components change.

If the wavelength of each color LED changes with brightness or each color doesn't dim proportionate to the others, that would just mean pre-processing of the image to keep the colors balanced. If dimming cannot be controlled so precisely, then the "On" time for the DMD while in each color time slot could do the fine control, but I think that would require TI rather than the manufacturer to engineer that. Or maybe it is even simpler and dimming the LEDs is not necessary at all and simply controlling the duration of the full power or zero power to each LED could accomplish it.

anyone know the input lag on this?

There is no way the input lag is any better than any of the other 4K models. This seems to be a problem with the XPR chipset not being able to work nearly as quickly as the 1080p chip sets do. 4K and serious gaming is a huge fail with DLP this go around. I would bet TI will address this at some point.... .... .... maybe.

This projector seems like it could be such a huge win, but the fan noise just completely kills it. I can't believe they would bother to release this without rethinking the entire cooling system. Make it an inch taller and put a large 120mm fan on the top to really move air and to cut the noise level by 10dB. Put a high quality fan in there that makes almost no noise. I can't even image how exciting this model really could be if the fan noise was nearly non-existent. How many people would be stoked to get a nearly silent LED projector with 4K for about $1,000.

But, nobody wants a noise factory. NOBODY!

They really want to want this, AAXA has shot themselves in the foot with the 4K1 and the excessive noise levels.

Obviously the 'user' picture settings that don't show you what you are changing was a huge mistake as well. But, this may be a limitation of a cheaper chip set in place and may not easily be corrected. The noise level is all on AAXA and their design. Trying to go as small as possible, then engineering a cruddy design and releasing it without anyone telling them it was unacceptable and would KILL sales.

Congratulation on making a product that everyone wants, but nobody will buy because of what you did to it AAXA.
