Hey Everyone my Xiaomi 4k projector automatically updated it's system software and I went looking to play a 3d movie but I have noticed they have removed the 3D setting on my projector since updating the system can't find it in display settings, now I can't play 3d movies, does anyone have experienced this or know how to solve the issue? Thanks

Do anyone connect media box / any player to avr, and avr hdmi out to the projector?

I keep noticing a slight slowness in video and sound sync, like it's not fully synchronise. Is this also the high ms you guys talking abt for gaming?

The video just seem slowed by a 10millisec!

I'm testing with himedia q10 Pro, the problem seems to be mx player. But I never notice issue with my TV previously.

With the player native player and Sony bluray Netflix app, its working well, video and audio are sync almost perfectly.

No idea why some player works well.

This is concerning... hope it was unintentional & they resolve it.

Two questions:

1) For those using this with a TV box i.e Shield: Does the machine allow you to boot to a single HDMI? I have the original white Xiaomi that always boots to the built-in AndroidTV and does not allow you to book to a Shield behind an HDMI. When using a Harmony remote, I can't set up a boot up sequence and still have to use the original remote to select HDMI 3.


2) I see that people have changed the language from the native Chinese to English via the APK, but is this APK just change the language of the built in AndroidTV Oreo 8? I assume since Oreo 8 has full english menu, why it wouldn't just be loaded instead of loading an APK to change Oreo's language.

Thank you!

This is very disappointing, 3d features is one of the reasons I bought this projector and now they have removed it, if I restore the operating system to its manufacturing setting that could possibly a solution but I don't want to do it yet as the language itself are still in Chinese and some in English, don't know where to go from here, I wish there is an easy contact hotline for Xiaomi.

Try pressing and holding the 3 bar menu button on the remote, you'll then get a pop up menu and can set the 3D options.

Finally I got a secondhand 4k apple tv for a great price, and I disconnected my previous setup (appletv hd, kodi in raspberry pi, fire stick and Nintendo Switch, all of them connected to a HDMI switch with a toslink/spdif output. This switch was connected to my previous plasma TV (now xiaomi projector) via HDMI, and to my Sonos system through spdif. This switch allowed me to avoid passthrough problems with my old pana tv)

I supposed I could remove the HDMI switch and use the toslink output of the Xiaomi 4k projector to connect the sonos system. Error. Whenever I play a video (4k or HD) or use streaming apps with the 4k apple tv, I have a huge audio delay in sonos. But when I use the proyector as player, everything works great. Obviously I bought the appletv because xiaomi miui tv software doesn't include any streaming app.

So now I probably would have to buy a new 4k hdmi switch... 😔
You got it all installed now? I wonder if the projector starts, when you turn on your appletv?

Easy solution: When answering any questions about specific vendors and pricing simply start a new thread in the Front Projectors Great Found Deals! section and direct the person asking the question to that thread. The site owners specifically created that section of the forum for best projector pricing/sourcing discussion.

Small lag is noticeable when playing games, at least with the Nintendo Switch. It's still nice, but I don't think FPS would play well with it.

For the power adapter picked up the UMI step-up voltage converter from Amazon, and it's been running without issue for a few weeks.
So what power did you choose for the voltage converter? is 500 W sufficient for this product or should go higher like up to 1000 W? Can we use 500 W voltage converter continuously for this projector?

did you try it with Game Mode? And without all digital enchantments? Like 4k upscale or some sort of "smooth" frame filters?
i've got a TV with input lag over 85ms ) so i hope that it will be smaller on this projector

Ordered from China yesterday; hope to receive in 2-3 weeks. Will compare with Optoma UHD51A 4K & 3D quality.

Look forward to read your review.
Was considering the uhd51a before I got xiaomi 4k projector. So far I'm enjoying it. Just getting the right projection on the screen is not as easy because it's not flexible in placement if you have a screen.

Placement should be easier than any ceiling-mounted PJ like UHD51A, which only has 15% vertical lens shift capability, and zero horizontal. Tabletop is easier w/UHD51A, but few of us want a PJ sitting on a table right in front of their seating area. For Xiaomi PJ, thinking of buying a simple TV stand like this to place below screen. Took quite a bit of effort to align my UHD51A w/screen in my condo given the limited space. After set-up though, I've been very happy with the PQ... sharper 4K than the Epson 5040UB & BenQ HT2550 I tried before it, and certainly much better 3D than both those PJ's (no crosstalk/ghosting, bright).

So far, none of the DLP projectors using pixel shift to achieve 4k resolution have shown fast input lag times. I'm pretty sure that is the nature of the tech. Fastest model tested is the Benq TK800 at 44ms. If you want sub-40ms at 4k resolution, you'll have to go native, Sony or Epson. DLP, forget about it.

Aren`t the Sony pjs like 100ms @4k input lag? With an input lag reduction feature that only works for 1080p at around 30+ms?

Thank you!

Help anyone with either of those questions? Thanks! =)

High Frequency beeping

hey people,
I received my 4k video projector today. The picture is great! The projector is already relatively loud, the fan can be heard permanently.
Unfortunately, a high-frequency beeping can be heard. Is this normal or do you have it?

Ah.. Me too gonna do the same.. My small kid just won't let me watch it if I keep the PJ down, within his hand's reach.
Which ceiling mount/stand did you go for?
Am looking for one that can swivel left-right, up-down & forward-backwards (planning to view on smaller 120" during day giving higher brightness & move backwards to view 150" at night).

Throw distance will be :

Don't see anything wrong with ceiling mount. But maybe don't mount in the ceiling but the front wall. There's so many USt mount available in amazon., just mount it on the front wall above the screen.they are quite adjustable too, angle, and distance from front wall.

But if you are using the alr screen, then it wouldn't work well as it no longer cancel the ceiling light.

The ALR screen needs to be mounted upside down if the projector is being ceiling mounted, so that it reflects only the light coming from top & deflects/rejects the light coming in from other angles.

Ceiling lights need to be taken care of then. They need to kept off when you will be operating the projector.
