Why when i play video from my LG G2 smartphone and mirror it to the Xbox One it isn't ...

No, the video in downloaded in 1080p. I realized that when I'm watching a movie or video from my phone, the picture is better when the phone is close to the Xbox. Thanks for your reply though.

Its probably the quility of the video.

Thank you for your answer. In this case, I'm not trying to use a pc, but a smartphone. I don't have a pc, that's why I mirror the smartphone display in to the xbox. Both mouse and keyboard are connected to the xbox console via usb. The keyboard works, I can type and use directions to control what happens in the smartphone, so I can both write and open apps by using the keyboard. But the mouse doesn't, there isn't something I can control to "click" in the smartphone as I would if it was a pc. I wish it was a way that I could control the smartphone through the mouse connected to the xbox usb port, the same way I can do it with the keyboard. The keyboard works fine, the mouse doesn't.

I have an Xbox One X connected to an LG soubbar that supports pass through and that is connected to a LG tv. I an getting video issues that also makes the atmos go out of control on my soundbar. I am also in the lasted preview program. Why is this happening?

The xbox 360 had optional media updates that allowed secure streaming from iPod devices to the xbox 360. Starting with the iPhone and iPod touch, these weren't able to be detected due the nature of how sophisticated an iPhones lightning cable is compared
to the 30-pin iPod nano, shuffle, classic connector.

My phone (LG G2) isn't detected by my xbox 360 no matter what I set the connection type to on my phone. Microsoft tried to push the zune and it obviously didn't take off so while that happened, they weren't caring much for Apple device support and I still
don't think they do by your experiences using it with an xbox one.
