Wait what?

How is everything hooked up currently?

In any case to hook up a 390X to a 4k TV you'll need a display port to HDMI 2.0 adapter and an HDMI 2.0 capable cable

Just unplug the monitor for a while and cycle the power button a few times

Would be a few minute wait if anything

 

Otherwise it doesn't work even if you go back to your original cables?

Well you could always reinstall windows to attempt to fix any software related issues

or just try fully removing the drivers with DDU and reinstalling them

I could try it but dont want to spend a long time to do it then it will be the same! I ordered a DP to HDMI adapter and will try with that some say it will not work some it will work the classic on the internet
