I think for a lamp based 1080p option the PX800HD is likely the best out there.

But for 4K laser UST, there’s not a single choice out there with low input lag, at least not that I’ve seen.

I use it on Nvidia shield at [email protected] without any trouble, i will try with my Razer laptop (GTX 1080).

What you meant is this projector will be able to play in this setting right as long as I connect an external player that is set at 4k 60hz?

Yes thats it....give it a try!

Anyone using this projector in a light controlled room with an average "white screen?" I have a cheapie FAVI HD-100 16:9/100-Inch Electric Projector Screen that I purchased over six years ago. I can virtually shut off all light to the room - 98%.

If so - how does it look? Thx - Rico.

Is this the same projector that this thread is about? The specs on geekbuying that you have linked indicate the native resolution is only 1080p but the projector “supports” 4K. Is that correct?

***I believe this is the right 4K version and latest model - MJJGTYDS01FM. AVS Forum Members "Wheelee" and "Movie78" were kind enough to provide the model number. Unfortunately - the other website referenced does not show the model number - - or at least I couldn't find it.

And I do not believe it's native 4K - some pixel shifting going on here. (See previous posts in this thread). I think one poster had both models and said the newer, 4K "support" Xiaomi was much better than the other model which also is native 1920 X 1080 & supports 4K but not like the newer model.

Hopefully some other forum members can clarify?

Yeah, the issue is the 4x shift required to make the 4k image. On another thread an engineer examined a technical data sheet from Texas Instruments and supported what I already had suspected, 40ms is the very minimum lag possible. If you add any image processing on top of that it only gets worse. Considering that most people looking for a UST are expecting all the functionality of a tv (frame interpolation, smart apps, presets etc) I don’t think we will ever see anything less than 65ms from a 4k DLP UST projector.
I decided a long time ago that anything serious like FPS or Racing really is better on my computer monitor anyway. The big screen is a nice novelty for games but quickly wore off. It’s fun to play Switch with my kids on the big screen, however when I want to get sweaty I prefer my desk and some good headphones anyway.

I agree with that. I too sometimes prefer the sharpness of a pc monitor and also a wired headset over playing on my projector and wireless headset.

Regarding 3D, the brightness reduced after selecting 3d option and there is pinkish tint to the video after converting. Hope this info helps.

To clarify more everything, the right model name for the 4K version is : MIJGTYDS01FM

Hereby attached also a copy of informations from "Mi info" app on my 4K laser projector.

Also, to make it really simple between the 1080p version (White) and the 4K version (Black) i would say that when you look at 4k sources on the 4K version, it looks like real and clean 4K and all 1080p sources are also sharper than with the white version. When you look at 4k sources on the white one, it looks like 1080p :-)

So the is 3D is not automatic you have to manually enable it?

Can you try some of the 3D MVC samples from the link below. Those should auto activate 3D automatically.

Just double check that - you have put an 'I' as the second letter, if you put this model number into Google it auto corrects it to 'J' as every site I have seen lists it with a J as well.

Ok i can be wrong but it make sense that "MIJ" are the 3 first letters of "MIJIA" or to be more precise "XIAOMI MIJIA".

Where do you go in the menu to activate the 3D?

Mi 4k Laser Projector Power Voltage Alteration From 220v to 110v ?

Hi guys,

It seems that Xiaomi is the only manufacture that actually puts out two different projectors for different markets.

The Mi laser projector 150 has a different model number for the 110v version compare to the 220v version in China. However the new 4k Mijia Laser projector only comes in 220v right now.

Is there a way to retrofit a 110v power supply into the Mijia projectors? I need to move my projector everytime I turn it off so a voltage converter is really inconvenient

This is a great question. If no way to retrofit, anyone in the US that got this care to recommend a good simple voltage converter that wont damage the unit but that also doesnt break the bank?

Edit: Looks like my order is actually coming with this adapter for free - will this even be suitable for powering the unit here in the US? https://us.********.com/samsung-cabl...pp_241363.html Fill in the stars with G e a r b e s t

As I said, when I first bought it I was impressed and had no regrets at all replacing it with my LG OLED B8..but here is the twist.

I just complemented it with a Bose 600 lifestyle and now I’m blown away with the quality of the video. I’m connecting the PS4 Pro to its amplifier and on through the projector’s ARC and man what a difference in colors and refresh rate. (Netflix and Movies through USB)

This is just crazy, my wife and I are just stunned by the picture quality, nonetheless the sound now too!

Note: Now I can see minor lag while playing COD vs connecting it straight to the projector. The game looks far better tho.

Now a question to the experts, what happened here?

I guess you can wait (and hope) until Walmart makes another deal with Xiaomi .

im still considering hard to confirm on my order for this xiaomi 4k projector, as im thinking of all the other $3k projector, not UST, may has good HDR projection too.

my current concern is the hdr content, from 4k bluray. read that the older xiaomi projector dont do well in the hdr area.

I've read at least one report (I think on Reddit or a YouTube comment) saying HDR makes things worse on the black Mijia 4K, so they ended up sticking with SDR. If you look up post #291 in this thread you'll find similar experience. From what I've read online, any projector in this price range using ALPD 3.0 will suffer from the same sucky HDR because they are limited to color gamut spec Rec 709 instead of the broader Rec 2020, so when you play HDR content the software has to do color mapping in an effort to project a decent Rec 709 picture, but ends up making things worse. Reviews of the Vava 4K projector with the same ALPD 3.0 tech will tell you the same thing.

I may just be reading your post wrong, but for the sake of clarity:

These are what the three gamuts look like on a gamut graph, the full spectrum is what our eye can see:



Rec709 is the smallest, DCI-P3 which some projectors cover in full and is the spec that many 'HDR' titles are currently mastered to is the next largest. Rec.2020 is the biggest, no TV or Projector, even $40k reference monitors can display the full gamut of Rec.2020 yet. But its good to have a colour space to work toward.

The Vava team claim to support 80% of DCI-P3 (which makes their "Rec.2020 coverage" claim a load of BS), so we can assume the Xiaomi is the same. This basically means it is not a HDR product, it cannot display the colours that are being used to create the HDR master. It is likely that when you switch it to a HDR source it is clipping colours outside the spectrum it is capable of showing and therefore looks like crap.

Rec.2020 is the biggest, no TV or Projector, even $40k reference monitors can display the full gamut of Rec.2020 yet. But its good to have a colour space to work toward.



The Vava team claim to support 80% of DCI-P3 (which makes their "Rec.2020 coverage" claim a load of BS), so we can assume the Xiaomi is the same. This basically means it is not a HDR product, it cannot display the colours that are being used to create the HDR master. It is likely that when you switch it to a HDR source it is clipping colours outside the spectrum it is capable of showing and therefore looks like crap.
The point I was trying to make was that you are better off sticking to SDR with this projector.

voltage converter won't be enough if the unit doesn't accept the higher frequency. And frequency converters are cost prohibitive.

So what is the solution? Do I need to hire an electrician to wire in as 220 outlet in my living room? How are others in the US powering their unit?

I just complemented it with a Bose 600 lifestyle and now I’m blown away with the quality of the video. I’m connecting the PS4 Pro to its amplifier and on through the projector’s ARC and man what a difference in colors and refresh rate. (Netflix and Movies through USB)

This is just crazy, my wife and I are just stunned by the picture quality, nonetheless the sound now too!

Note: Now I can see minor lag while playing COD vs connecting it straight to the projector. The game looks far better tho.

Now a question to the experts, what happened here?
There's less image enhancement (processing) when the projector is being fed a 4k signal. Which is why you should always send a 4k signal, even when watching 1080p content.
Of course, this is not always possible, depending on your source. If you're passing through a modern AVR, this can be set in the Video settings.
My marantz AVR have an enhanced HDMI mode, where true 4K 60p, 4K 50p in RGB / YCbCr 4:4:4 YCbCr 4:2:2 is enabled, up to 12bits.

You will get a much smoother image with a better color range. This will eliminate the issue some users have experienced with blowouts of certain colors on HDR content and stuttering with scrolling text.

Please note, this applies to all the Xiaomi Mijia and Wemax projectors.
