It's on their page https://www.vava.com/products/4k-ult...aser-projector

Scroll down to Downloads section.
There is no firmware link just notes mentioning 1.42


Edit: turned on my projector and it prompted to download and install 1.42
phara and ra990 like this.

Looks like this firmware finally took care of an issue I was having with my Shield TV thinking it had Dolby Vision support. It no longer prompts me to enable that.

Do you have latest shield? I have 2015 version and it wasn't prompting me on 1.33

Yep, I have the new one. It's a cool little unit. Do you get the AI upscaling features on your 2015 one? If not, that would be worth upgrading for, especially with this projector. The quality of that upscaling is remarkably good.

I don't think it has AI upscaling my 2015 has been working flawlessly so I haven't had the need to upgrade it yet. Will take a look at AI upscaling reviews

Does anyone has more information about the real native contrast for the Vava?

I'v read that the 0.47 chip the Vava will max at 500 native contrast.
Some say that Vava and Xiaomi are cheating and not turning off dynamic dimming all the way resulting in higher native contrast measurements.

Most reviews put the Vava at 2500 native contrast and same reviewers put the LG Hu85la with the 0.66 chip at 2100 or so native contrast.


Hope someone with a Vava can share some accurate measurements here, and thoughts about Vava and Xiaomi "cheating" the native contrast measurements.

I think it was in the review, but I don't recall the link you will have to use search.

Visually contrast seems the same on my Xiaomi 1080p and Vava. Do I care about them cheating? Nope. I like the image on VAVA enough to keep it.

So in Xiaomi there was no physical button to turn off the unit, in Vava you can't turn off the unit from the UI, only remote or physical button on the unit. At least in the latter case they could add this in the firmware.

Modified wire shelf to protect the UST and move it around. Took 30 minutes to cut metal. Eventually will build custom shelf for it, but this will at least protect it until then

Dimensions are just right depth and height wise

Hi,

I'm looking for a full firmware for this device. Could any of you could check with a file explorer such as mixplorer if a /dev/block/backup file exists and could be accessed ?
In the meantime, I'd also be interested in firmware updates if any of you has kept the downloaded files (there is no firmware update on their website).
Thanks !

It's been pretty quiet in here. How is everyone liking their VAVA? Mine is still going strong with no issues. I tried using the the calibration settings from the projectorreviews.com site (https://www.projectorreviews.com/vav...calibration-2/) and they do give a better picture than the preset video settings, though I had to tweak them a little to my liking.

Nothing bad or new to report. I use it daily and loving it over my retired Xiaomi 1080p. Better colors, sharper image, brighter and quieter. Sure 24 Hz support would be nice, but I don't have much content. I still have until end of the months to return it if anything, but I don't see any reason.

Has anyone figured out how to track how long you have been using the projector? Other projectors usually have setting in the menu where it keeps track of lamp life, but I haven't found anything like that for the VAVA.

I think you might be forgetting that it has 25k rating and you can't change "bulb". This will last you at least decade assuming nothing else goes wrong with it

I didn't forget about the 25k hour laser engine life rating, was just wondering if there was a built in way to track projector usage. I've been a little crazy with mine and probably use my projector 50+ hours a week.

Didn't see the counter in Xiaomi or VAVA, but I wouldn't worry with high usage. Even if you do 50 hours a week that's 2600 a year, so you are right at about 10 years when you hit that mark. Personally I don't keep gadgets that long and will probably replace it in 3-4 years with something better. Pretty sure we'll have loads more options and cheaper by then anyway.

Do you mean you generally use it for something other than movies? Almost all movies are 24p.

***I've been looking at 4K UST projectors for some time now. What are some of the features/benefits that people are looking for in a UST?

Obviously, price is important. How about no coil whine? (Or very little) 3D support? 24 Hz support for movies? Lens shift (I'm not sure that's the right term for a laser UST but an easier way to align the picture to the screen?) I believe this segment can really put a dent into large screen TV sales. The ease of installation is very important. I know you have to deal with a screen and make sure it's very flat and the right material for your viewing conditions but outside of that, it sounds like "set it and forget it" for many years once it's setup properly.

Actually I haven't watched too many movies recently. I do use it with Youtube streaming a lot though. When I do watch I use Netflix.

Fair enough. Netflix movies are 24p though (assuming you're using a client that switches to 24Hz appropriately).

Honestly this is the only thing holding me back from buying this projector, can't believe they didn't add support for this. Very frustrating. I don't suppose they've ever mentioned addressing this?

I use Shield for everything. Maybe the content I watch isn't 24 hz or i just don't notice it. I hope they added it but I don't recall they ever mentioned about adding it.

To my (limited) knowledge, being fairly knew to the UST projector game, none of them have "lens shift". They are fixed wide angle lenses and picture alignment is a combination of projector and screen placement with tweaking done by what is essentially just electronic/digital keystone correction.

Installation isn't complicated. The screen needs to be plumb and the projector square to it, but the projectors are extremely sensitive to the smallest movements/adjustments. Someone should actually come up with a mechanical "pad"/"set-up plate" to set them on to "dial-in" placement with the screen in extremely fine increments, instead of just nudging it around on top of a cabinet or whatever it's sitting on. So "set it and forget it" may not be a reality, because all it takes it someone bumping it or whatever it's sitting on and the image may not be perfectly lined up on the screen anymore.

***Much thanks. I know with a regular, lens projector - - keystone corrections are discouraged. I imagine that once it's setup, you're good to go and hopefully, it's in an area where there isn't much traffic where it can be "bumped" a lot. A fixed, setup plate is an interesting idea. Maybe an entrepreneurial, AVS Forum Member will invent one. Cheers.
