Connecting projector (EPSON EH-TW5900) into HDMI results in incomplete
supported modes detected:
$ grep . /sys/class/drm/card*-*/modes
/sys/class/drm/card0-DP-2/modes:720x576
/sys/class/drm/card0-DP-2/modes:720x480

/sys/class/drm/card1-eDP-1/modes:1920x1080
/sys/class/drm/card1-eDP-1/modes:1920x1080
Above is with "Hybrid Graphics" selected in BIOS.

However doing the same with "Discrete graphics" selected I get:
