No Signal on new Samsung 4k

Hi everyone, I'm a new TiVo Bolt owner. I just upgraded my television to the Samsung UN55KS8000 and can't get anything from the TiVo to it.

Here's what I've tried so far:

-Reset/Wiped the TiVo.
-Used TiVo supplied hdmi cable and certified 4K hdmi cable.
-Tried all inputs on the Samsung
-Tried auto resolution and set resolution on TiVo settings.
-Plugging and unplugging hdmi while TiVo is on.
-Confirmed that all other hdmi devices I have work fine. (PS4, HTPC, etc.)

TiVo works instantly when I plug it back into my 24" 1080p tv. I know others have had intermittent issues with hdmi on 4K televisions but I can get anything at all. Any help would be appreciated.

Thanks!
