Dual display strange behavior, no signal over HDMI, but recognized by PC

Thanks in advance.

Short and sweet, I have an Acer monitor and Toshiba TV connected to a single GTX970. The monitor is connect over DP, and the tv HDMI.

The system recognizes the TV but I do not get any signal. If I reboot the PC, I get the imagine on the TV (which is display#2) until I login, then it switches back to DP and I no longer have signal again.

On top of that, the image quality is...funky. Looks like scanlines and colors are not correct.

This is not the first time I have had this PC and TV connected over HDMI, but it IS a new cable and a new GPU.

All settings look correct to me, I can't figure this one out.

Thanks.
