Basically the title.

I have an intel 4690 and gtx 970 system that i've been using for the last 2 years with a 144hz monitor and a 40 inch 4ktv next to it connected via hdmi 2.0 and with UHD color turned on to enable 60fps at 4k. This has worked fine with 0 problems whatsoever for the last 2 years.

This week I got a new system with Ryzen 5 2600x CPU and RX Vega 56 GPU. I just plugged the HDMI into the system thinking it would all be fine but no. The monitor is fine but the TV is constantly flickering ever few seconds with the screen going black before coming back on and resuming the flickering and black-screening.

I'm confused as to why this is happening when my system is way more powerful and able to handle this.

Anyway to fix this?
