Couple of brief questions:

Will Dell update this device to "optimize" it for screen casting in the future? I am using a Chromecast and it gave me a message this first few times I casted the screen that this device is not optimized for screen casting. Hopefully this is on Dell's to-do list?

Short of Dell updating the device capabilities, what can I do to optimize it myself? The issues that arise are that, say when I'm watching Amazon Video with the screen cast, during scenes of high action or rapid movement, the picture will become "squared out". So far when it gets really bad, I disconnect the screen cast and reconnect and it is OK for awhile, but inevitably, say 20-40 mins later, it's back at it. This brings to mind another question: how come this issue doesn't happen when I'm casting YouTube, which has built in app casting? What makes the difference between the app cast and the screen cast (Amazon Video doesn't app cast with Chromecast)? Also, the issue is less prominent the closer I set the device to the cast dongle.

I don't have service with the tablet; I use my home WiFi. Would enhancing my WiFi performance (speed, etc.) help the issue? My WiFi is in the attic, while my TV is on ground level. And it's a old style house, so thick walls, etc. There are undoubtedly ways I can speed my WiFi. They aside, would that help the screen cast?

The recently released Amazon Fire Stick cast dongle has a processor 4x faster than the Chromecast dongle. Now, using the Fire Stick would eliminate the issue when using Amazon Video as there is app cast with the Fire Stick dongle for Amazon Video, but would the better processor also aid for better screen casting?

Thanks in advance!
