TV Only work duplicated

[Kriggs]

I just bought a new 4k TV to use as a monitor, everything fine on first plug but adjusting the hertz settings from 59 to 60hz made it go crazy, now only shows "background noise" when set display only on it and the info shows 2400x1080@60hz, I have another monitor and when set to duplicate it, it works fine, how can I set the standard resolution/refresh rate of this TV without seeing anything it in?

 

I tried:

- Safe mode, changed the resolution there but came back to normal

- Switching all cables

- Reinstalling AMD drivers

- Blindly change the resolution/refresh rate, but it always end up in some other screen, I've practiced how to do it in the working screen, but cannot manage it

 

What else can I try?

Plug in both screens at the same time and set to Extended desktop, then use the working monitor to change settings.

 

TV/film standard is 59.94 Hz instead of 60 Hz, don't worry about changing that, for practical purposes "59 Hz" (rounded in the menu, but it's 59.94) and 60 Hz are the same thing.

The settings window stays on the non working screen, cannot change the working to primary without it, tried moving but no way I could find it, any keyboard shortcuts to move the window between monitors?

Awesome, now I have it working with extended desktop as well, but when showing only the TV still bugs out

Don't have any other computer but have an Android, installed Chrome Remote Desktop and solved it, now I can try overclocking to 1080@120hz without fears, thanks!
