Galaxy pro 10.1 not full screen while miracaating?

[khampson]

Hi why when I miracast the screen to my smart 55 inch lg TV it has a black border all the way round? It's not full screen and really annoying, I have had a play but can't see any settings to change it, any advice thanks

I believe it's because the screen resolution of the Tab Pro is not a perfect 16:9 aspect ratio. I originally purchase an older 9.7" Galaxy Tab from Costco and it had a resolution of 1024x768 and I tried the miracast to my Samsung TV and it was almost a perfect square in the center of my 55" TV with black bars around all sides that were at least 6" in width. After messing with it for a while it dawned on my to find out what aspect ratio 1024x768 is equivalent to and it is 4:3, hence the square. I then returned it and went to BestBuy and picked up the Galaxy Tab Pro 10.1" and it is much better but still some black bars.
