I bought this model over the weekend and found on trying to watch a 4k movie through it, that the audio couldn't keep up with the picture. Also it caused this diagram of instructions on how to use the remote to come up in the bottom corner of my screen, spent the better half of my afternoon trying to figure out how get rid of this display, after googling the problem I realized I wasn't the only person with this problem from a Panasonic machine. I ended up taking it back and getting a different brand. Haven't had any problem since. Definitely would not recommend. But I must say the friendly staff at JB HiFi were great when dealing with the return.
