Hey, I have this pretty bizarre issue right now. I have two identical monitors (Dell U2414H), both connected to my computer via DisplayPort. On one of them the output dynamic range (and also output color format) settings are missing. This is a problem because it defaults to limited color range. Currently my workaround is to jiggle the hue slider around for the monitor, which causes it to snap back to full color range. This is only a temporary fix though, because every time the monitor turns off (screensaver, putting computer to sleep, etc), the problem returns. Both monitors are set to RGB input in their firmwares. Does anyone have any ideas?
