To enable CEC:

Hit the ' 3 line' button on the Mijia remote to bring up the control menu. Within that setting you'll see CEC controls. Once enabled, the projector should turn on with the Shield power up. That's not the challenging part as many of the modern day turn on via CEC just fine. The challenge is to have the harmony remote work in-place of the Mijia remote and turn OFF since I couldn't CEC to turn it off.

At first I couldn't get this to work, but it turns out I was in the right place with the Mijia, but only had some bug where wouldn't pair with the Harmony. Yes it detected the Harmony just fine as a bluetooth, but wouldn't pair. I simply rebooted the Mijia and returned to the same pairing page and it eventually paired. If you see 'Harmony Keyboard' on the Mijia bluetooth device... you're on the right track. =)

I used the Xiaomi Fire TV trick which I had previously working for my last white Xiaomi 150 since the Mijia works with the Amazon FireTV remote. So add Amazon FireTV on the Harmony as you would pair a fresh FireTV to your Harmony. This may not work if you have existing FireTV as it may confict.. But know it does work.

Now I'm on a single start where my Shield, Denon and Mijia would all turn on properly and put me in the Shield home page with a shortcut. And the remote's OFF works to shut everything down gracefully.
I tried this last night and it worked perfect, thanks so much! I can now use only my harmony remote again.

Hi,

I received my Xiaomi 4k ust now I'm wondering which the best screen to order in a 100" scenario would be. Two of my candidates got also mentioned in this thread.

1. XY screen ZHK100B-PET Crystal

2. Samsav T Prism ALR screen for ust projector

I found no reviews or comments for the Samsav screen, does anyone have that screen and can share there experience with it and maybe how it compares to the XY screen?

Thanks for your help

Can't tell you about the Samsav, but I have the XY in 120" and a bright environment, so at 100" you should get very nice performance. it's funny bright at night, so if you don't need to use it in daytime lighting, you can probably get away with a much cheaper screen.

I finally received mine. Looks amazing! But with a young kid in the house I'm instantly worried that the small remote will be lost or broken. Could I buy any MiTV bluetooth remote to replace it? They seem to look identical.

No noise other than the light woosh of the fans spinning up. It's in a very quiet basement room, too, so anything abnormally loud/annoying would be instantly noticed.

Interesting observation on the fan. My unit is very quiet until the fans need to kick into higher gear to cool the projector down. I find that running mine in HIGHLIGHT mode which is brighter has the expected result of running it harder and thus hotter. This makes the fan run louder. Nothing to the point of it being distracting when I'm immersed in the movie or drowned out by the audio. However running in highlight is a must for me for the best PQ and brightness, so it's a non compromise situation personally. Since I have my projector inside a pull out drawer, I do plan to run some quiet computer fans to help me with the circulation which I'm hoping will further reduce fan effort. This would look ugly for those that have the unit sitting pretty on a table, but my projector is hidden so I'm able to add fans without making it an eye sore. One of the many small projects to get done....eventually.


Separate question. For those that upgraded from a previous Xiaomi: I found that this one projects a picture that is approx 4-5" higher than the white version. I had my screen perfectly aligned and assumed it would remain so given this new one is in the same body. not so.. I'll have to raise the screen eventually, but does project quite a bit higher. Anyone else notice this?

One more interesting thing:

I use google chrome cast 4K to watch Netflix. When I connected it through my onkyo amplifier and the to Xiaomi 4K projector and try to use hdmi 2.0 then I lose video (it appears then disappears for few seconds etc.). When I switch off hdmi 2.0 then everything is fine but I can not can 4K resolution only FullHd.

Connecting chromecast 4K Directly to Xiaomi and enabling hdmi 2.0 works (and I have 4K video in Netflix)

Any ideas?

HDCP issues, maybe? Check your receiver compatibility with 2.2.

I now got both projectors at home and I'm happy to say that the Mijia 4k really does 3840x2160. I use the projector as my PC monitor. That was the main reason I wanted to upgrade. Media programs and games, etc looks so much better with the projector matching the resolution I use on the PC.
I mentioned in my previous post that I was worried that the Mijia 4k was less bright than the Wemax One Pro, but its not. Both projectors, on the same setting (on HIGHLIGHT) and the Mijia 4K actually looks slightly brighter than the Wemax. So the 7000 vs 5000 lumens is just a marketing thing.

Another thing worth mentioning.

The Wemax had a great keystone system. (Standard 4 or 8 point adjustment) with great flexibility.

But the Mijia 4K has done away with that, instead it has some useless, very limited system where you can only set the angle. This means it's much more difficult to set the height and width of the picture. you actually have to move the unit itself around and go find more magazines to put under it etc. Super annoying, especially if you have a fixed projector screen to display onto. The Wemax was SO EASY...


Otherwise i was very happy with the Wemax, but the Mijia 4K definately has better image quality.

Cheers

Where are u located and where did u purchase the Xaiomi mijia 4k from?

Please can someone confirm if it has the same Picture Profiles? Monitor, Game, User, Picture etc.. Monitor is the most important to me though.

Also, does it has the same 3D Options, Frame Packing for 3D Blu-Rays, does it works well?

Thank you!

How long have u had the 1080p one? any deadpixels on it?

Thanks

4K, great picture quality but framerate locked at 60Hz, and bad 3d experience, for 60Hz 4K content it's great though but not for 24P

What I did is to add a device to my harmony with the cell phone app and for manufacturer put Amazon and for device type put FireTV. The next screen says please pair your Amazon FireTV with the remote and I went into settings on the projector, bluetooth and devices. Scrolled down and (This took several attempts) I finally saw Harmony keyboard. and selected it.
Once it paired, I added my activity with it. I had to go into the handheld remote settings and change all of the buttons to my shield TV that I use, but now it will power it off with the 20 second countdown when I turn off the activity.

What @BenPlace said. =) May take you a couple times and try restarting devices if they don't seem to play nice.
