Stream from Linux to your devices without a dummy HDMI plug
I wanted to share this tip for people struggling with the lack of a virtual display when hosting on a Linux machine without having to use a dummy hdmi/dp plug. My main rig uses an ultrawide (3440x1440) and the TV in my living room is 4K. As of now I haven't been able to pass through HDR content so I disable/enable it when streaming. The following settings allow me to use Sunshine/Moonlight without issues.
The kscreen-doctor commands allow me to change my display settings so they match what I want it to look like on my TV. There's plenty of documentation for kscreen-doctor so I recommend checking it out to finetune your settings to your own likings.
