Screen mirroring problem, Tablet Z

[vaiosan1]

I am screen mirroring from my Tablet Z to my new Sony KDL-50R550R 50" LCD TV. I am trying to screen mirror a variety of 720p .mov files using the Movies app or MX Player, which play perfectly on my tablet, but playback on my TV is very choppy and repeatedly freezes for up to a second or so.

My other problem is that I will not upgrade to the latest firmware (Android 4.2) because of the unsatisfactory "phone style" UI (I found it so inferior to the original Sony skinned Android 4.1 version that I downgraded back). So, I don't know how I can upgrade with any improvements to the mirror cast firmware, at least until Sony decides to tweak the 4.2 (4.3?) firmware upgrade to include a UI appropriate for a 10.1" landscape mode tablet.

Thanks.

You can not update to 4.2 and keep the 4.1 UI 

as far as mirroring

Screen mirroring

Use Screen mirroring to show the screen of your device on a TV or other large display without using a cable connection. Wi-Fi Direct™ technology creates a wireless connection between the two devices, so you can sit back and enjoy your favourite photos from the comfort of your couch. You can also use this feature to listen to music from your device via the TV's speakers.

Your TV must support screen mirroring based on Wi-Fi CERTIFIED Miracast™ for the functionality described above to work. If your TV does not support screen mirroring, you need to purchase a wireless display adapter separately.

When using screen mirroring, the image quality may sometimes be negatively impacted if there is interference from other Wi-Fi® networks.

To mirror the screen of your device on a TV screen

1. Follow the instructions in the User guide for your TV to turn on the screen mirroring function.
2. If you are using a device with multiple users, make sure you are logged in as the owner, that is, the primary user of the device.
3. Drag the status bar downwards, then tap .
4. Find and tap Display > Screen mirroring.
5. Tap Turn on Screen mirroring and select a device.

When using screen mirroring, do not cover the Wi-Fi antenna area of your device.

Thanks. I know how to use screen mirroring, and yes, I realize I can't have the 4.1 UI with the 4.2 upgrade - that's why I downgraded back to 4.1.

Intereferenec with other WiFi networks was something I considered, although I've had no real trouble with my Samsung AllShare Cast direct WiFi connection to the TV, using similar technology, I presume.

As for covering the WiFi antennna - that would be where, on the Tablet Z?

I wonder if anyone can help. I have new Z1 phone and new z tablet. I cannot get them to mirror screen to each other. Just says no device found. I think I've switched everythingbon correct
