Question How am I getting 4k 60Hz on my 1080p TV when it only has HDMI 1.4a ports using Nvidia Custom resolution?

It's a trap!
You're not. Whatever is telling you you're running at 4k/60 is incorrect. Or maybe your device is attempting to output at 4k/60 but 100% chance thats not what the TV is running at. If you have Nvidia custom set then its maybe rendering at 4k/60 but its downscaling before output to the HDMI port.
