After my research, I was unfortunately unable to find the original power cable, but the Alpha Elettronica KD7032/19 desktop power supply should work. The power data matches the projector. However, I cannot guarantee 100% that a suitable plug is included in the scope of delivery. Otherwise you would have to contact Xiaomi directly.
I have had the projector for some time now. But I have no problems with the Internet connection. Is the WLAN router possibly too far away from the projector?
The same problem is also the case with my device. However, the connection only breaks off in the first 15 minutes. But then it finds it again. Unfortunately, I haven't found a solution yet. But I'll get back to you when I know something.
I don't know the Sonos Arc, but I can tell you how it works for me: Wireless audio works (Bluetooth). However, an ad-on may be necessary to use certain protocols. I can use the appropriate interfaces and protocols via Kodi 19.2 to control my audio devices.
The best thing to do is to check what interfaces this Sonos Arc has and compare them with the beamer.
Hoi - if nothing works there: https://helpcenter.digitec.ch/hc/de or directly: in the user portal (orders) enter return (RMA case) - Yes, too bad, ...ithappens...good luck
The size of the picture depends on the distance to the wall. At 1.5-2m, you will have an image equivalent to a 75-85 inch TV. As far as I know, you cannot adjust the size of the picture.
I also have mine in my bedroom, but not facing a wall but the ceiling so I can lie on my back and watch films :)
The connections are really at the back, so you can't put the projector on its back to project onto the ceiling.
However, you can mount it on a tripod thanks to the thread at the bottom. Depending on the tripod, you should be able to project onto the ceiling.
A possible workaround.
Hello Tobias
I only use the beamer as a standalone device. The Smart Home System on it can be used well. There is also a screen-mirroring function, but I haven't tested it yet.
I don't really see any problems. In our holiday flat, we only watch TV via mobile phone. The mobile phone is connected to the TV, but with 4G it works without problems.
Accessories:
Adapter to iPhone - HDMI
Unfortunately, this will not work, the beamer is operated with an external power supply and according to the manufacturer it consumes less than 65 watts.
Power consumption: <65W Max. (in highlight mode)
Input voltage: 19V DC
Standby power consumption: <0.5W
We don't have a screen and direct the projector against the ceiling or wall (painted white) and that is tiptop.
The main thing is a white flat surface without structure.
The projector has a normal HDMI connection like any television. It doesn't matter what you connect to the HDMI. Whether a laptop, a console or your Apple TV. It works without any problems. Image and sound are simply transmitted via HDMI.
I don't remember which apps are preinstalled. But it is the Google Store (equivalent to Apple's Appstore) where you can download all possible apps that are also available for AndroidTV. For example, I have Netflix, Disney+ and Youtube installed. These are the apps I need.
