4K output on AML-S905X-CC, or overscan
I tried to connect my Le Potato to an LG 4K TV. I thought that the specifications of the AML-S905X-CC included 4K output over HDMI. After attempting to connect it to a 4K TV, and then re-reading the specs, I really don't know what I bought. Does it support "VP9 P2 4K60 Hardware Decoding" or "4K UHD with HDR over HDMI 2.0"? Both of those are quoted from the Kickstarter page.
Can anyone help me get 4K output from my device? I believe I'm running the most recent Love R Pi system I can get via "apt-get upgrade". Here is my "uname -a" output:
Linux libre 4.14.7-gaaa79797e37-dirty #4 SMP PREEMPT Tue Dec 26 03:19:50 EST 2017 aarch64 aarch64 aarch64 GNU/Linux
On my 4K TV, the 1080P output of my Le Potato extends beyond the boundary of the screen. Is there any way to turn on underscan/overscan to bring my 1080P output into the bounds of my screen?
I'm fine with 1080P output, as long as I can see it. Thanks,
