HDMI output resolution limited to 1080p for Intel HD Graphics 520
Fedora 33
Linux: 5.12.8-200.fc33.x86_64
xorg-x11-server-Xorg-1.20.11-1.fc33.x86_64 (don't think it matters one bit)
Under Windows 10 I get 1440p/60Hz by default without doing/configuring anything.
Under Linux I have to meddle with xrandr or Xorg configuration files. I don't like it. I want it to work out of the box.
