used hdmi cable to play a video through the tv. when finished, no matter how we tweak display settings, laptop screen will backlight, but nothing will display unless plugged into tv.

Thanks for reporting your bug.

Since reporting Krandr has since been replaced by KScreen. It is available in the Plasma 4 series, and is default in Plasma 5 onwards.

I hope this solves your issue. If you still have a problem after upgrading please reopen a new bug under kscreen.

Thanks
