Okay,

1) There's no such thing as a HDMI 2.0 cable. A HDMI cable is a HDMI cable, that's all. There exists HIGH-BANDWIDTH HDMI cables, but they are NOT called HDMI 2.0 cable. To put it in very, very simple terms; the HDMI cable is simply a transport for data from point A to point B.

2) Check your TV's manual on WHICH HDMI port is designated to support HDCP 2.2. Not all TVs has equal HDMI ports, usually low-end TVs only have ONE HDMI port that supports HDCP 2.2.

3) A 4k TV does not automatically mean that it has HDCP 2.2. HDMI 1.4 can pass 4k but at 30hz, of which does not require HDCP 2.2. Many 4k TVs from 2014 and 2015 suffer from this issue.

4) You can try and buy a HDCP stripper like a HD Fury integral, but it's going to cost you, A LOT. Perhaps as much as your TV.

5) Again, a HDMI 2.0 cable does not exist and HDCP 2.2 was stated to be required for the PS4 Pro by Sony.

6) No fix will come, because there is nothing to fix. If it doesn't work, it's simply hardware incompatibility. The only remedy is that you get the correct hardware.
I cannot find your TV's manual online, so I cannot verifiy for you. But basically if point no.2 is not available on your TV, then sorry to say but you're screwed.
