Chromebox displays on one TV but not the other

So I just got an ASUS Chromebox M004U and installed LibreELEC. I wanted the same setup I have with my Raspberry Pi 3 which it would replace.

I set it up on my older Samsung TV because I couldn’t get it to display on my newer JS8500. My first thought was that LibreELEC can’t output to the higher resolution of the newer TV but then I realized if it worked with the RP it should work with the Chromebox.Although I tried different HDMI cables they still make a difference. And again, if it works with the RP it should work for this too.

Anyone have any idea what it could be or what I can look at to fix this? The newer TV is our daily driver and I’d rather have it there.

Thanks in advance.
