You can press Win+P to choose which screens to enable.

The RX 580 doesn't support HDMI 2.1.

Didn't think about RX 580 support of HDMI 2.1

I did all the changes, will take a look.

Noticed a weird monitor behavior - monitor darkens an output image even on th Win10 desktop but the cursor itself remains with previous brightness. Even if i increase brightness from the monitor menu it is still much darker and almost no brightness increase after that. Reboot helps to solve it. Maybe i didn't reboot PC after CRU manipulations, maybe i did some other changes, who knows .

That's a bug in AMD's driver with Polaris GPUs and not an issue with the monitor. It happens randomly when the driver loads if there's an EDID override. If it happens on boot, you can press Ctrl-Shift-Win-B to refresh the desktop.

Great! Thanks a lot. You know all answers to my questions.
Thanks for your support.

Hi, how do I straight up, Delete "Greyed Out Data Blocks" in Detailed Resolutions in Extension Block or why do i have to delete everything including hdmi audio to get the new resolution work & show up in Resolution Display Settings?
R9 290 = HDMI 1.4A = up to 3840x2160 @ 38hz I've tested it. My display 3840x2160@60 support HDMI 2.0. Hisense 43A6H 4k 43 inch tv.

I don't understand what you're asking. You shouldn't have to delete anything. Your TV doesn't support HDMI 2.0 according to what you showed me. It only supports 3840x2160 @ 60 Hz with YCbCr 4:2:0.
