When i got my mind set to do something, you can bet your ass i'll try every damn method i can find. Even if it's in some obsure post i only found on 1 site. Turned out to be the working one too. Just a note though, after i attached that dummy plug. My main monitor no longer showed the ROG logo upon boot (applies to accessing bios too), no screen until lock screen. Seems like the onboard hdmi takes priority over that. Plug the monitor into that one and yup, visuals. But hardware decoding/encoding at least on my end currently results in severe artifacts.
So if the potentially artifact resolving tweak above doesn't fix the glitching, i'll disable QS again in the bios. I can live with a slower encode, i can't live with video artifacts
