Twin hdmi out or hdmi splitter

Hello,

Hopefully a straight forward question, but cant seem to find it any where documented.

I am planning to get a 4K TV in the next couple of weeks. I also have an av receiver which is hdmi 1.4 only meaning it can not handle 4k.
If I get a say Odroid C2 or any thing similar will I be able to use a hdmi(2.0) splitter and plug one directly to TV and another to av receiver just for audio with out any issues?

I would want audio bitstreamed to my av receiver and video to TV. My source is external hdd with only 1080p movies currently but will contain 4k movies as well.
If this can really work suggest me a sample hdmi splitter that will work with hdmi 2.0 please.
