Hi guys,

During the last 2 weeks my Xiaomi 4K projector shows some white vertical lines in the whole left side of the image, from top to bottom. They are a lot, and usually appear after turning it on, and dissapear after some minutes, or when I do a calibration. I'm quite worried becaused it was purchased in China by XY Screen for me, and it was sent together with a PET CRystal screen, and I live in EU. So it will be a disaster if I have to send it back to china to be repaired.

I'm going to make a video with this problem for reference.

Any ohter guy with a similar problem? Do you think it's a hardware or a software problem?

BIGBEAR2004 08-23-2019 08:39 AM

I purchased a Mijia 4K projector with an XY 120 inch PET screen, but at the last minute I decided that an acoustic transparent screen would be better for my future build as there will be no place for my speakers with a PET screen. I am probably going to put this unopened PET screen in the classified. However, if there is a work around I would prefer to keep the screen. I tested this projector on a white wall in the dark, and so far its awesome! Definitely worth it.

Sure, here you go.

My projector screen is about 46 cm away from base.

The motorized tray is adjusted to be about 9 cm tall from base.

The height of Xiaomi projector is elevated about 2 cm tall from base, and only the front, the rear is left intact hence from the side you will see that it is tilted towards the projector screen.

The reason why it is done so because I started the adjustments by having the projector laying flat completely and slowly work my way towards getting it full screen.

It took quite a bit of trial and error as you will also need to perform keystone corrections at the same time until you get the optimal setting, but eventually you will be able to get it with patience as the part for raising/lowering the is now easily tackled with the motorized stand.

Hope this helps!

Hi,

Just realised I left out the distance between the projector and the wall.

Approximately 39 cm apart.

Could you please share some information and pictures of your motorized tray? I am considering something similar, so any information would be greatly appreciated?

If you haven't already, you should ask for a counterpart sample from XY-Screen. This way you can compare it side by side to see if it's indeed the same thing. I'm very curious because if they're the same and word spreads, XY would need to lower their prices. Better for the consumers!

It doesnt resolve the problem, just tested.

There is one other guy (at least) here in Spain with the same problem...

I remember another guy who had blinking white spots all over the screen. If I remember correctly he solved the problem by turning down 12bit Colour resolution to 10bit.
I don't have a Mijia yet to tell you how to do it but maybe it helps.

what are you connecting to the projector? if its a pc and you have an NVIDIA GPU
1. Change your resolution to 3840 x 2160 (or 4096 x 2160) and apply
2. Below the resolution select 'Use Nvidia color settings'
3. For Output color format select: YCbCr422 and apply
4. For Output color depth select: 10 bpc and apply
5. For Output dynamic range select: Limited and apply

If you had the same issue as me this will resolve your issue.

Hi guys,

Im thinking of pulling the trigger on one of these baby's but need to make sure I can use my existing pull down screen with it? I currently have a 106' screen (Sapphire Manual Slow retraction Screen - 234 x 132cm (16:9) - (SWS240WSF-ASR2)


Would this still produce a good picture?

I do not think this screen will work. You need a tension screen. This one appears to only be weighted by the bar.

Hey Ben, thanks for the feedback.

That’s a shame, it’s pretty stable when it’s down, what reasons are their as to why this wouldn’t work? I can’t have a fixed screen unfortunately.

The screen has to be perfectly flat, you will see the slightest wave in it. You do not have to have a fixed screen, they make tensions screens that pull down.

Here is an example of a pull down tensions screen.

PAUL7331 08-27-2019 11:38 AM

Thanks Ben. I might hit the purchase button and see how I go with it, if I need to purchase a tab tension screen then so be it!
I must add I’ll be watching projector only at night and with blinds closed so it’ll be pretty damn dark. Dont suppose this matters???

No, what you will see is waves on the screen instead of a flat image.
If you can afford a tensioned screen, go ahead and get the projector and you can always get the tension screen if yours doesnt work.
