HDMI second monitor issue

Hi, I've got a problem setting up second HDMI monitor.

Connecting the very monitor with VGA works perfectly fine. Arch detects HDMI connection as HDMI2 (for some reason xrandr outputs HDMI1 and HDMI2, yet just one physical HDMI on my ASUS R558UQ laptop) and xrandr pretends it works, however no image is screened and monitor says cable is not connected.

I've somehow managed to connect HDMI monitor before and I'm (vaguely) recalling it was initialized as HDMI1. My guess is HDMI1 might do the trick, but it seems I'm unable to do this. I've tried switching from nouveau to nvidia to intel without any luck; xrandr --setprovideroutputsource and --setprovideroffloadsink fails on every combination except existing one. The issue arised after an (unsuccessful) attempt to connect HDMI projector.

Any help would be greatly appreciated.
