During first drivers installation for Asrock Radeon RX570 my monitor, connected via HDMI cable, turned off (like there were no signal) for at least 10 min. After reboot my RX570 doesn't work. After that i deleted all graphics drivers, bought DVI cable, installed latest driver version. Now my monitor doesn't work via HDMI (no signal) but works via DVI.

Monitor (Acer R241Y) and HDMI cable checked - they work with my notebook. Problem remains on different motherboards: Gigabyte A320M-S2H and Asrock FM2A68M-DG3+. Driver 26.20.15029.20013 (01.04.2020) "working properly" according to windows device manager. OS Windows 10.

So what's happened during drivers installation and how can i fix HDMI connection?
