Odroid boot question

Hi all- I have OpenPHT on a couple of devices, and am happy to ssh into my new box, if need be:

I have a brand new Odroid C2 - grabbed the plex player via github (OpenPHT-Embedded-1.6.2.123-e23a7eef-Odroid_C2.aarch64.img.gz) and wrote to card using ApplePi-Baker. Upon boot, I get a scrambly screen (my TV is a bit older, but like less than 10 years old, so I think all things should be fine), which makes me want to add a line of code from this discussion, but it hasn’t worked:

Am I dumb, and just can’t figure out where to put the code?

Help please!

Solved: I had to comment out 1080p60Hz and uncomment 1080i60Hz in the boot.ini file. Whew!
