GNOME Shell shows brightness slider even when I don't have a monitor capable of brightness control

GNOME Shell shows brightness slider even when I don't have a monitor capable of brightness control (this is a desktop machine)
Same here with 3.12.0 .
Still an issue in the 3.13 branch
Still an issue, can this get some attention before 3.14 final? I think showing the brightness slider on a desktop PC is weird and makes the system look a bit unpolished.
We do what gnome-settings-daemon tells us to do.
What's the output of: xrandr -q --verbose and: udevadm info --export-db

DVI-0 says it supports brightness. That's a bug to file against the display driver I'm afraid.
Ah, another (special) instance of this issue is Bug 783508.
